The EtherCon Connector
Pro64 Series products feature locking connectors for all network I/O. The
Neutrik® EtherCon connector is a dual RJ45‑type connector that can receive
a standard Category 5e cable or a cable fitted with the special locking
EtherCon connector.
When using a standard Cat‑5e cable, plug the cable into the center of the
EtherCon jack; release the cable by pressing on the small plastic tab built into
the cable connector.
The locking EtherCon connector is similar to an XLR plug, the kind commonly
used on microphone cables. Insert an EtherCon‑equipped cable into the
jack until it clicks and locks in place. To remove the cable, press on the metal
release tab at the top of the panel‑mounted EtherCon jack and pull the
connector outward.

AC Power
Always plug the unit into a properly grounded (earthed) outlet. Always use
the AC line cord that was shipped with the unit. Grasp the power cable by the
connector and never by the cord itself when connecting and disconnecting
it from the power source.
Do not expose the Pro64 device to moisture, rain, or excessively damp
environments.
AC Line Conditioning
Aviom products are digital devices and as such are sensitive to sudden spikes
and drops in the AC line voltage. Changes in the line voltage from lightning,
power outages, etc., can sometimes damage electronic equipment.
To minimize the chance of damage to your equipment from sudden changes
in the AC line voltage, you may want to plug your equipment into a power
source that has surge and spike protection. Power outlet strips are available
with built‑in surge protection circuits that may help protect your equipment.
Other options for protection of your equipment include the use of an AC
line conditioner or a battery backup system (sometimes referred to as an
uninterruptible power supply, or UPS).
Rack Mounting
Pro64 products are designed to be mounted in a 19‑inch equipment rack.
The rack ears on each side of the device are designed to support the weight
of the product without additional hardware. Each rack ear contains holes for
two screws per side. Always support the unit with all four screws to avoid
damage to the unit.
To rack mount the Pro64 product, position it in the equipment rack at the
desired location. Use standard rack‑mounting screws (10‑32 size) to attach
the unit to your rack hardware. Tighten all four screws firmly, but avoid
overtightening.
Aviom suggests the use of non‑metallic washers between the rack‑mounting
screws and the device’s finished surface to avoid marring the finish on your
Aviom products.

Transporting the 6416m in a Rack
The 6416m Mic Input Module has attachment points for rear support
hardware built into the product’s sides. If the 6416m is to be rack mounted
and transported frequently, be sure to support the rear of the unit with
appropriate mounting hardware that matches the size of the rack used to
avoid damage to the product.
Ventilation
The 6416m is convection cooled and does not require a built‑in fan. Always
allow adequate ventilation for devices mounted in equipment racks. Avoid
placing your Pro64 product directly above or below other rack‑mounted
devices that produce high levels of heat, such as power amplifiers.
Do not block the side and back vented openings in the product’s case. The
openings in the top may be blocked as long as the temperature immediately
around the unit remains below 50°C. Although use in ambient temperatures
exceeding 50°C isn’t recommended, leaving an open rack space above the
unit will provide additional margin in extreme temperature conditions.
Cleaning
Before cleaning a Pro64 product, turn off the power switch and unplug the
unit from the AC power source.
To clean the surface of the Pro64 product use a clean, soft lint‑free cloth that
has been slightly moistened with water only. For tougher dirt, use a cloth
slightly dampened with water or with a mild detergent. Always be sure to dry
the surface of the unit before proceeding with use.
When cleaning your Aviom products, never spray cleaners directly onto the
product surfaces. Instead, spray a small amount of the cleaning solution onto
a clean cloth first. Then use the dampened cloth to clean the product.
Never use solvents or abrasive cleaners on the finished surfaces of your
Aviom products.

About A-Net
Aviom’s A‑Net® is the only networking technology conceived, designed, and
optimized for managing and distributing audio using ordinary Cat‑5e cables
(or fiber by adding the MH10f Merger Hub). As implemented in the Pro64®
Series products, A‑Net can transmit up to 128 channels of uncompressed
24‑bit audio with the reliability and fidelity of analog, and the power and
flexibility of a true digital network.
Pro64 A‑Net allows variable sample rates in three ranges, from 44.1kHz
to 192kHz , with ultra‑low latency, jitter, and wander. Pro64 devices can
be connected in any combination of serial (daisy‑chain) or parallel (star)
topologies. Cable runs between Pro64 devices can be up to 400 feet (120
meters) on Cat‑5e1, and miles on fiber optics (with Aviom fiber‑capable
equipment).
Because A‑Net is designed specifically for audio, the technological limitations
of Ethernet and Ethernet‑based products are removed, while audio
performance and system flexibility are increased. A‑Net incorporates Aviom’s
unique patented and patent‑pending algorithms for controlling clock jitter
and wander, as well as system‑wide latency—regardless of an installation’s
size, design, or clocking setup. A‑Net offers significant advantages in fidelity,
performance, and flexibility over Ethernet‑based products.
A‑Net uses the “physical” layer of Ethernet, but it eliminates all the protocol
elements that are designed for computers and IT‑style networking. In
audio applications, these other layers reduce efficiency, impose system
restrictions, and introduce latency and timing instability. By eliminating
Ethernet data structures, A‑Net creates a superior network with enhanced
audio performance. With A‑Net and the Pro64 Series, Aviom continues to
break new ground in the design and development of innovative digital audio
networking technologies and solutions.

rates, from 44.1/48kHz to 192kHz . Because no sample rate converters are
used, audio transmission is kept fast and clean, eliminating the audio artifacts
and signal degradation inherent to sample rate conversion—even when
syncing to an external clock source.
Any Pro64 I/O module can be designated the Clock Master for the network,
generating and distributing its internal clock. Digital I/O modules are capable
of syncing to and distributing an external clock from a Word Clock or AES3
source to the network.
Control Data
The Pro64 Series has built‑in, dedicated bandwidth for 14 channels of
non‑audio control data through the use of Aviom’s innovative Virtual Data
Cables™. These data streams are always available to carry MIDI, RS‑232, RS‑
422, or GPIO (General Purpose I/O), and they never compete with the audio
channels for network resources, regardless of the system configuration. (Not
all VDC™ data types are supported on every Pro64 module.)
Because VDC inputs are simply incorporated into the A‑Net stream, these
control signals can be transmitted over very long cable runs and even across
an entire Pro64 network, significantly expanding the applications possible
with MIDI, RS‑232/422, and GPIO. And as with audio signals, VDC control data
can be input anywhere and output anywhere else in the network.
A-Net Ports
Pro64 I/O modules have dual A‑Net ports, labeled A and B. Both ports carry
a bidirectional A‑Net stream at all times. (That is, both ports are always
transmitting and receiving A‑Net data.) Pro64 networks can be configured in
one of two operational modes, Auto Mode or Manual Mode, depending on
the requirements of a particular system.
In Auto Mode, there are no connection rules; connect a Cat‑5e cable to either
the A or B port and the system does the rest. Auto Mode provides a true
audio network with 64 available “Slots” for transporting audio (at 44.1/48kHz).
Every audio Slot is available everywhere in the system, with no upstream/
downstream restrictions.
In Manual Mode, the Pro64 network becomes a 64x64 system (at 48kHz),
similar to a traditional stage‑to‑FOH snake. At every point in the Manual
Mode network, two 64‑channel streams are available on the cable and in
each module. The configuration of the cables and ports has an impact on
the makeup of the network and the distribution of audio signals. The user
can direct A‑Net data from an input module to a specific port (A, B, or both).
Output modules can be configured to output audio signals received from a
specific A‑Net port (A or B).

Support For Pro16 Series Products
Pro64 Series products can be combined with Pro16™ Series output products
such as the Pro16 Monitor Mixing System by adding the Pro64 ASI A‑Net
Systems Interface. This 1U module converts Pro64 data to Pro16 data,
providing up to four streams of 16‑channel data (depending on the Pro64
sample rate) that can be used with A‑16II and A‑16R Personal Mixers, A‑Net
Distributors, and AN‑16/o Output Modules.
The ASI is not compatible with the A‑Net output of Pro16 input modules such
as the AN‑16/i, AN‑16/i‑M, the Y1 console interface card (for Yamaha® digital
products), and A‑Net console cards built by third‑party manufacturers for
their digital console products.

Firmware Notice
All Pro64 devices in a network should be updated to use the most recent
firmware version to ensure trouble-free operation.
As new Pro64 modules are released, older Pro64 products need to be
updated so that they recognize the features and functions of the newer
modules—something that is especially important if one of the older devices
will be used as the network’s Control Master. (If for some reason you cannot
update the firmware on older Pro64 devices before using them, set the
newest module to be the network Control Master.)
Pro64 Update Tool is a free Windows software application for updating the
operating firmware in Pro64 Series products.
The Pro64 Update Tool requires a direct RS‑232 (serial) connection between
the computer and the Control Master device on the Pro64 network. Normally
this is accomplished by connecting a null modem DB9 cable between the
RS‑232 jack on the computer and the Pro64 device. Complete information on
using RS‑232 (and USB‑to‑RS‑232 adapters) is available on the Aviom website.
Updates take just a few minutes per module.
Pro64 Update Tool is designed to run on a PC under Microsoft® Windows® XP.
It has also been tested and found to be compatible with Microsoft Windows
Vista®. Mac users can run Pro64 Update Tool using Windows XP running
under Apple’s Boot Camp program on Intel‑based Macs.

Pro64 Interface Conventions
Many Pro64 Series products have similar user interface components,
including buttons, LEDs, and switches. When describing the features and
functions of Pro64 Series products, the following conventions will be used.
Cat-5e
All Cat‑5e connections between A‑Net devices should use Unshielded
Twisted Pair (UTP) cable. The cable can be of the stranded or solid type; solid
wire performs better over long distances, while stranded wire is more flexible
and easier to manipulate and therefore easier to work with in a performance
situation where short cables are required.
Cables designated as Cat‑5e in Pro64 documentation can be interchanged
with any Cat‑6 (or better) cable. Cables will be referred to simply as “Cat‑5e.”
Connectors on Cat‑5e cables can be of the standard RJ45 variety or locking
Neutrik EtherCon type.
Button Presses
When referring to specific front‑panel labels, LEDs, and buttons, or when
describing a Pro64 function that requires the press of a button on the front
panel of a device, a special typeface will be used. For example, “Press the
En t E r button to confirm the sample rate change.”
Buttons that work in combination, giving the user a choice when performing
an operation, will be referred to as one unit. For example, “Changing the
sample rate requires the user to confirm the change using the Enter/Cancel
buttons.“
Changing Values
When editing values on the front panel of a Pro64 device, some operations
will require the use of the inc/dec buttons (short for increment/decrement) .
These buttons scroll up and down through a list of available values. Holding
the button down does not accelerate scrolling. The front panel of a Pro64
module is marked only with indicator arrows.
Pr o 64 in t e r F A c e co n v e n t io n s
9
Download from Www.Somanuals.com. All Manuals Search And Download.
The buttons with up/down indicator
arrows are used for the inc/dec
functions.
Buttons of this type will be referred to as “inc/dec” buttons.
Selecting Values
Some settings, including Sample Rate, Network Mode (Auto or Manual), and
Virtual Data Cable type, require the user to select from a range of values.
The button that controls the selection of a value is referred to generically as
the “selection button” for that function. For example, “Use the Sample Rate
selection button to scroll through the available rates.”
Pressing a selection button repeatedly will scroll through the available
settings and will wrap around when the end of the list is reached.
Pressing the selection button will cycle
through the available values.
DIP Switches
Illustrations of Pro64 DIP switch components indicate the switch handles in
black, as seen below.

Pro64 User Interface
This section outlines some basic concepts of operation for Pro64 products.
Pro64 I/O devices have some common user interface elements that make
setting up an audio network easy to understand.
Common elements include:
• A‑Net Slot selection
• Network Mode (Auto/Manual)
• Sample Rate display
• Managed button
• Edit Lock button
• Enter button
• Cancel button
• Virtual Data Cable (VDC) configuration
In addition, each I/O module has the ability to be set as the Control Master
and/or Clock Master (depending on the actual makeup of the analog/digital
modules in the audio network). Only one device can have control of these
functions at a time in a properly configured Pro64 network.
Basic Actions
Most system‑level operations in the Pro64 user interface require the use of
the Enter button to confirm an action. For example, assigning a Virtual Data
Cable port to a VDC Slot or choosing a new sample rate (on the Clock Master
device only) will require the user to press the En t E r button to confirm the
request. If no press of the Enter button is detected within a predetermined
time frame, the system will automatically cancel the request and return the
device (or entire network) to the previous state.
Operations that do not require the use of the Enter/Cancel buttons include:
• Stereo channel link (input modules)
• Channel activation (input modules)
• Channel on/off (output modules)
• Gain settings (input modules)
• Output level settings (output modules)

is required to complete the action. To confirm an operation, press En t E r . To
exit an operation without completing it, press the Ca n C E l button.
A-Net Slot
Pro64 I/O devices come in a variety of configurations. To allow a large
number of hardware audio input devices to be available to the Pro64 audio
network, Aviom has implemented the concept of the A‑Net Slot to simplify
the configuration of potentially complex audio networks.
A Pro64 audio network will always have a finite number of A‑Net Slots
available that can be addressed by an unlimited number of hardware
channels. The actual number of available Slots is determined by the current
sample rate.
Slots versus Channels
You might be wondering why Aviom chose to refer to the audio I/O resources
in the Pro64 Series products as ‘’Slots.” Why not just call them “channels”?
We did this to avoid confusion between references to hardware audio
resources and network audio resources. The word ‘’channel’’ is ambiguous
and may cause confusion when configuring an audio network. “Channel”
appears in many contexts, including audio mixing consoles, mic preamps,
DSP processors, and DAW software.
We use the word ‘’channel’’ when referring to the physical audio inputs—
Pr o 64 us e r in t e r F A c e

analog or digital—on a piece of hardware (such as the 16 mic/line XLR input
jacks on the 6416m Mic Input Module). Each of these audio inputs can be
made active and added to the network individually, and it is only when
activated that they use any network resources (the A‑Net Slots). To enable this
powerful feature, Pro64 products separate the hardware resources from the
available network resources with a button that allows each hardware input
channel it to be added to the network as needed.
It is these activated hardware resources that are being referred to as “Slots.”
Pro64 audio networks can potentially have a greater number of audio
channels and hardware I/O devices connected than the network can make
use of at one time. This provides flexibility without requiring constant re‑
patching or complicated computer programming.
Keep in mind that a Pro64 A‑Net network can only manage a specific number
of Slots at a time, and this number varies with the sample rate being used.
The maximums are 64 Slots in Auto Mode at the 48kHz sampling rate and
64x64 Slots in Manual Mode at 48kHz.
In summary, think of “channels” as hardware resources that can be added
to the network as needed and “Slots” as locations within the digital audio
network pipeline that A‑Net uses to move data throughout the network.
Slots and Sample Rate
The current system‑wide sample rate will determine the number of A‑Net
Slots that are available. Auto Mode and Manual Mode have the same number
of Slots at each sample rate; only the direction of the data is different.

Even though the network sample rate may change the available number of
A‑Net Slots, the capacity of a hardware device does not change. That is, a
16‑channel input module in a 192kHz network can still have all of its channels
activated; all of its physical inputs can operate at 192kHz.
The current sample rate will also affect the display of available A‑Net Slot
ranges. Slot ranges will always have the same maximum number as seen in
the sample rate chart. At 96kHz, for example, only Slots numbered 1 through
32 are available; the Slot range from 33 to 64 is inactive and unavailable at
that sample rate. Slot ranges outside the maximum for the current sample
rate can be selected, but attempting to activate a channel in an unavailable

range will result in an error message (the selected channel button, A‑Net Slot
range, and sample rate LEDs will all flash).
A-Net Slot Display
Since the capacity of the Pro64 network could be as high as 64 A‑Net Slots,
Pro64 hardware I/O devices need a way of routing a selected hardware
channel to a selected network Slot. In the upper left corner of the front panel
of a Pro64 I/O device, the A‑Net Slot display and its associated inc/dec buttons
are used to select a range of Slots that the hardware device will address.

Network Modes
A Pro64 audio network can be set to operate in one of two modes, Auto or
Manual. The network mode can be selected on the front panel of the device
designated as the system’s Control Master.
Both modes are fully bidirectional at all times, regardless of the system layout
or design.
Auto Mode
Pro64’s Auto Mode takes most of the work out of managing resources in an
audio network. This is the “everything everywhere” mode. Channels are sent
into the network and can be shared by all devices in the network, regardless
of how the modules are connected and regardless of the physical location
of any module. Output modules do not need to follow input modules as in a
traditional analog system. In Auto Mode, both A‑Net ports (A and B) function
identically.
Once configured for Auto Mode, the system ensures that only one hardware
input channel is activated into a given A‑Net Slot. There is no limit to the
number of hardware output channels that can use a given A‑Net Slot. The
actual number of available Slots is determined by the current sample rate.
The maximum number is 64 active channels at the 44.1/48kHz sample rate.
Sample Rate

88.2/96kHz
176.4/192kHz

Manual Mode
When more than 64 channels are needed in a network, Manual Mode can
be used to provide configurations of up to 64x64 channels. Two unique
64‑channel streams are available at each module. In Manual Mode, the A and
B A‑Net port connections can be used to direct and route A‑Net data.
Pro64 input modules can send their audio inputs to either or both A‑Net
ports, while output modules can listen to data from either port. For a
traditional stage‑to‑FOH snake system, this allows the user to configure a
system with up to 64 sends from the stage and another unique stream of up
to 64 returns to the stage.
Manual Mode operation removes the restrictions of unique channel‑to‑Slot‑
range relationships found in Auto Mode. Slots can be overwritten, allowing
the user to replace channels from one part of the network with new data.
This means that, while no more than 128 channels can be in the network at
a particular location, there is no practical limit to the total number of audio

Pro64 Network Concepts
Configuring a Pro64 network involves a few simple steps. This section details
some of the global settings and network concepts that you should be familiar
with when setting up a Pro64 system.
Control Master
In every Pro64 network, one device will always be designated as the Control
Master, the device that manages all A‑Net resources for the network. The
Control Master can be any I/O module in the network, and can be assigned or
changed by the user as needed. Only one device can be assigned as Control
Master in an audio network at a time; an A‑Net network cannot function
without a Control Master.
The functions of the Control Master include:
• System resource and information management
• Setting network mode (Auto or Manual)
• Management of active channels in Auto Mode
• System‑level command and control functions
• Keeping track of all Pro64 devices in the network (by type
and quantity)
• Control of the current system‑wide sample rate
• Clock Master (analog modules only)
• System lock via password on/off
• Management of Virtual Data Cable (VDC) resources
• Management of stereo link status
• Requests to enter Managed Mode
The Control Master status is identified with a red LED on the front panel
of the device currently assigned as the Control Master.

Setting Control Master Status
Setting the 6416m to be the Control Master is done using the DIP switches
found on the rear panel. The Control Master switch is part of the Virtual Data
Cable port section of the interface.

In the VDC section, locate the 10‑position DIP switch in the RS‑232 area of
the rear panel. Switch #10 will set the 6416m to be the Control Master for the
Pro64 network when the switch is in the on (up) position (the up position is
shown in black in the diagram above).
Control Master Functions
This section describes the individual functions that the designated Control
Master device in a Pro64 network controls.
Enumeration
When the Control Master is powered on, its first job is to identify and count
all connected A‑Net modules in the network in a process called enumeration,
similar to a PC booting up and loading its operating system. The time for this
process will vary based upon the number of modules in a system.
Enumeration is an automated process performed by the command and
control portion of the A‑Net software. There are no user‑controllable
functions or settings.
co n t r o l MA s t e r

During the enumeration process, all connected A‑Net modules will flash their
A‑Net LEDs, indicating that a request to be added to the network is being
made. Once granted entry by the Control Master, the individual module’s
blue A‑Net LED will light solid to indicate that it is now receiving valid A‑Net
packets and is part of the network.
6 416
m
The blue LED in the A-Net icon is used to indicate network status.
If valid A‑Net packets are not received, the module will reset and wait until a
valid A‑Net stream is detected.
During enumeration, any conflicts will also be resolved. For example, consider
a new Auto Mode installation using eight input modules set to the same
A‑Net Slot range with all channels activated during a bench configuration.
When all these input modules are connected and then powered up, only
one of them will be allowed to have all 16 channels activated. The remaining
seven modules will have their audio channels deactivated.
Adding Pro64 Modules to a Network
When a new device is added to an existing network, the new device makes a
request to the Control Master for inclusion in the network. During this time,
the new module’s blue A‑Net LED will flash. When the new module has been
enumerated by the Control Master, its blue A‑Net LED will then light solidly
to indicate that the Control Master has granted the module access to the
network. Adding a new module will interrupt network operation briefly.
Changing Settings
Most operations on Pro64 modules that make system‑wide changes require
the use of the Enter and Cancel buttons. For any operation that requires
confirmation, the LED between the Enter and Cancel buttons will flash
to indicate that the user needs to press one of these buttons in order to
continue.
Press En t E r to complete the operation or press Ca n C E l to exit without making
a change. This rule applies to all functions that can be changed by only the
Control Master.

designated as the master clock device.

When an analog I/O module such as the 6416m is the Control Master, there is
no other analog module that can be used as a clock source. When a digital I/O
module such as the 6416dio is part of an audio network, the digital I/O device
can be used as a Clock Master for the network, even if this digital device is
not the network’s Control Master.

External clock sources on the 6416dio Digital I/O Module can include:
• Word Clock ‑ via the dedicated BNC Word Clock jack
• AES3 (AES/EBU) ‑ from AES3 digital stream 1/2
When the 6416m is set to be the Clock Master, only its internal clock source is
available; there is no external clock input on analog Pro64 modules.
Clock Errors
If a clock error occurs, the Clock Master LED will blink indicating that an error
has occurred. Common causes for a clock error include:
• Attempting to change the sample rate on an analog device
other than the Clock Master in an all‑analog network
• Attempting to change the clock source when the network
is password protected
• Removing or changing external clock sources on a digital
I/O module
• Incorrect configuration of an external clock source on a
digital I/O module
Network Sample Rate
When the 6416m is the Control Master in an all‑analog network, it is
automatically designated as the Clock Master. It will remain the Clock Master
until a different analog module is made the Control Master or until a digital
module such as the 6416dio Digital I/O Module is added to the network and
is set to be the Clock Master.
The Clock Master LED will light automatically on the Control Master when
that module is powered on. (Only a digital I/O module can be the source of
the network’s master clock without being the Control Master.)
The system’s internal master clock is derived from the sample rate currently
in use. The sample rate also affects the total number of available A‑Net Slots
available for use in the network.
The Sample Rate section of the 6416m front‑panel interface includes a group
of LED indicators for displaying the current network sample rate. One LED
will be lit at all times.

Press the selection button to cycle through the available sample rates.
The current sample rate for the network will be displayed on all I/O modules

Changing the Sample Rate
To set or change a network‑wide sample rate from the Clock Master, use the
button below the Sample Rate LEDs to select a new rate. Pressing the Sample
Rate selector button will cycle through all available sample rates, flashing
the value for the new rate. At the same time, the LED between the Enter and
Cancel buttons will flash, indicating that pressing one of these buttons is
required to confirm and complete (or cancel) the operation.
Changing the sample rate will affect the number of available A‑Net Slots
when the sample rate changes from the 1x range (44.1/48kHz), to the 2x
range (88.2/96kHz), to the 4x range (176.4/192kHz) or vice versa.
Note that Yamaha devices are not compatible with sample rates above 96kHz
when a 6416Y2 card is included in a Pro64 network.
Auto/Manual Mode Selection
The Control Master can be used to set the current network mode for the
system to Auto or Manual. As with the system‑wide sample rate, the network
mode is also a global setting.
The network mode selection controls are in the same part of the user

Managed Mode requires the use of a computer with the Pro64 network for
tasks such as firmware updates, system monitoring, control, and editing.
The Control Master is the only module that can allow the network to enter
Managed Mode.

To manage a Pro64 network with a PC, the PC needs to be connected to the
Control Master using a DB9 null modem cable connected to the RS‑232 port.
The RS‑232 baud rate DIP switches must also be set to the same rate as the
PC application.
Exiting Managed Mode is also done from the Control Master. Pressing the
lit Ma n a g E d button followed by the En t E r button will return the network to
local control. Attempting to enter or exit Managed Mode from any module
other than the Control Master will cause the Managed button LED to blink to
indicate the error.
Password Protection
All Pro64 devices ship with a default password. However, a Pro64 network
can be password protected from the Control Master only. Once protected,
the front‑panel interface on all modules is locked, preventing changes to
A‑Net Slots, sample rate, clock source, channel activation, stereo links, and
Virtual Data Cable assignments. Hardware switches, such as gain settings
on input and output modules, and rear‑panel DIP switches are in the analog
domain and are not affected.
Password protection remains in force even when a system is power cycled.
When a network is password protected, the front panel interface can be used
to get information on channel Slot assignments and VDC routings. Pressing
a channel button will display its Slot assignment in the A‑Net Slot display.
Pressing the VDC inc/dec buttons will cycle through the fourteen VDC Slots,
displaying any port assignments on the current module, as well as the In Use
LED for all active VDC Slots in the network. This query behavior is similar to

6416m Network Settings
There are a few basic concepts that need to be understood when setting
up a Pro64 network. Some of the functions described below do not need to
be set on every Pro64 device in the network as they only need to be set up
on the network’s Control Master, the module in charge of network resource
management.
Control Master
One Pro64 module in every network must be designated as the Control
Master. To set the 6416m as the Control Master, DIP switch #10 in the Virtual
Data Cables™ section is used. Set this DIP switch to the up position with the
power off to avoid conflicts with network resources.
When the 6416m module is then powered up, the network will be enumerated
and the blue A‑Net LEDs on all connected Pro64 devices will be lit. On the
Control Master device, its red Control Master LED will also be lit. The Control
Master LED will be off on all remote/slave modules in the network.
Control Master Errors
The following rules apply to the Control Master and active Pro64 networks.
If a slave module in an active network is incorrectly switched to be a Control
Master (in addition to the network’s already functioning Control Master), that
module’s Control Master LED will light and the blue A‑Net LED will go out to
indicate the error. The Control Master LED will remain lit until the module is
returned to slave status, at which point the A‑Net LED will light to indicate
that the module is now part of the network.
If a new module set to be the Control Master is added to an active running

Control Master LED will light but its A‑Net LED will not. Its audio I/O resources
will remain unavailable until the module is returned to slave status. All audio
on this module will be muted until the module is set to be a slave.
If the Control Master is removed from a functioning network (by being
disconnected, power failure, etc.), all slave units will reset and audio will be
muted. Slave units will wait for a new Control Master to be designated and at
that point will begin the enumeration process. Once the network has valid
A‑Net communication, audio resources will become available.

A-Net Slot Range Configuration
The A‑Net Slot section of the interface is used to set the range of A‑Net Slots
that the 6416m will use to send its active audio channels into the network.
There are two components: the A‑Net Slot display and the inc/dec buttons
used to select a value.
A-NET SLOT
Press the up/down buttons to select an A-Net Slot range.
The A‑Net Slot display will move in increments of sixteen Slots and the A‑Net
Slot range display will wrap as it reaches the end of the list of available values.
The number shown in the display corresponds to the base Slot in a group of
sixteen sequential Slots, one per channel button. The available base Slots are
1, 17, 33, and 49.

Keep in mind that the number of available Slots is determined by the current
network sample rate as set by the Clock Master.
Setting the A-Net Slot Range
To set a base range for the 6416m, use the inc/dec selection buttons found
below the A‑Net Slot display to select the desired range. When the selection
button is pressed, the new base Slot number will start to blink in the display,
as will the Enter/Cancel button’s LED. This indicates that confirmation is
required to complete the change. Press En t E r to set a new base Slot or press
Ca n C E l to exit without changing the base Slot and return to the previous
setting. If no press of the Enter/Cancel button is detected within a brief
period of time, the interface will automatically cancel the change request,
returning to the previous state.
Setting a new base Slot range on the 6416m will deactivate any currently
active channels.

Network Mode
The LEDs in the A‑Net Transmit section show information about the current
network mode, which can be set to Auto Mode or Manual Mode only at the
network’s Control Master. When the Pro64 network is operating in Auto
Mode, the red Auto LED will be lit on all modules, and no user settings are
available on a per‑module basis. When using Auto Mode, it does not matter
which rear‑panel A‑Net port (A or B) is used when connecting I/O devices to
the network.
A-Net Transmit
The A‑Net Transmit section of the 6416m interface is used when the network
is in Manual Mode. In Manual Mode, the red Manual LED will be lit and user

Clock Master
One device in a Pro64 network will always be set as the network’s Clock
Master. In a network with only analog I/O modules, the module set as the
Control Master is also set to be the Clock Master by default. The Module set
as the Clock Master will have its Clock Master LED lit.
When digital I/O modules are used in a network, incoming Word Clock or
AES3 (also referred to as AES/EBU) digital data streams can also be used as
clock sources. It is only when a digital module is part of the network that the
Control Master and Clock Master can be separate devices.
Set the 6416m to be the network Control Master using DIP switch #10, found
on the rear panel.
Sample Rate
Pro64 networks can operate at sample rates in three ranges without the use
of sample rate converters. The current network sample rate also determines
the number of available A‑Net Slots.

the error.
Sample Rates and A-Net Slots
Changing the network sample rate has a direct effect on the availability of
A‑Net Slots. For example, setting the sample rate to 96kHz makes only 32
Slots available, numbers 1 through 32. Slot numbers above 32 are no longer
available.
If at the 48kHz sample rate an input module such as the 6416m is set to the
Slot range starting at 33 or 49 and has active channels, these channels will be
deactivated when the sample rate changes to 96kHz. These Slot assignments
no longer exist in the network.
P No t e : When using 6416Y2 A‑Net cards in Yamaha® devices as part of your
Pro64 network, only sample rates up to 96kHz are valid; Yamaha
devices cannot utilize the 176.4/‑192kHz rate.

6416m Front Panel Features
This section describes the features and functions of all front‑panel
components of the 6416m Mic Input Module. Many of the network‑wide
settings are common to other Pro64 modules and will be familiar to users of
other Pro64 devices.
A-Net Slot Configuration
Each I/O module in a Pro64 network can be set to operate within a specific
part of the network, referred to as its Slot range. The actual number of Slots
available in a network is determined by the current sample rate; at 48kHz,
there are 64 Slots available, for example.

A-Net Transmit
Each input module in a Pro64 network has the capability of transmitting
its input channels into the network. When using Auto Mode, the network
manages the access of these channels to the available Slots. Auto Mode is
indicated with a red LED in this section. No user options are available in this
part of the interface.
In Manual Mode, the user decides how input channels will be distributed to the
network. Inputs can be sent to the A port, B port, or to both ports at the same time.
Assigning the 6416m to send active inputs to the A‑Net ports is done with the
A‑Net Transmit selection button. Press the button to cycle through the various
choices.

designated as Control Master. Once a module is enumerated and is part of
the network, the blue A‑Net LED will light solid. The LED will remain lit as
long as valid A‑Net network data is received.
The A‑Net LED will flash during a firmware update when the module being
updated is part of an active network. When a module is being bench configured
(it is not part of an active network), the A‑Net LED will be off during the firmware
update. (Check the Aviom website for current firmware updates.)

engaged from the network’s Control Master.
When using a PC for firmware updates, etc., a Pro64 module cannot have
its RS‑232/422 or MIDI port assigned to a VDC when the PC is connected.
Deactivate these VDC assignments before entering Managed Mode.
Connecting a PC to the Control Master requires the use of the RS‑232 port for
communication. The RS‑232 baud rate DIP switches also need to be set to the
same rate as the computer application for data transfers.
To enter Managed Mode, press the Ma n a g E d button; its LED will flash. The
Enter/Cancel LED will also flash. Press En t E r to confirm the mode change or

In Auto Mode, each A‑Net Slot is unique. The Control Master manages the
availability of A‑Net Slots and will grant or deny a channel activation request
from an input module based on the current makeup of the network, the
sample rate, and the Slots already in use.
To activate a 6416m input channel within a given A‑Net Slot range, press
its numbered aC t i v E button. (Note that the word “Active” does not appear
on the front panel user interface.) If the Slot is available, the Control Master
will enable the Slot and the channel’s green LED will light. If the Slot is not
available, the LED will flash briefly, indicating that the requested Slot is in use
elsewhere in the network.
In Manual Mode, a channel can be activated at any time. Depending on how
the network is set up and configured, activating a channel can replace a
same‑numbered Slot that was added to the network elsewhere.

Channel Activation Rules
It is not necessary to press the En t E r button to activate or deactivate a
channel.
Each Pro64 module remembers a unique set of active channels for Auto and
Manual Modes. For example, an input module could have channels 1‑8 active
for an Auto Mode application and channels 5‑6 and 12‑16 active for a Manual
Mode application. Changing network modes will restore the active channel
status for each connected module.
P No t e : The active state for the channels on a 6416m is not saved as part of
a mic pre Preset.
Changing the A‑Net Slot range will clear the currently active channels on
an input module automatically to protect against channel/Slot conflicts or
unintentional overwriting in Manual Mode.
Level Meter LEDs
Each input channel on the 6416m Mic Input Module has its own set of six
level LEDs—green, yellow, and red. Green LEDs are used for all levels up to
‑6dB. The yellow LED lights when the signal level reaches ‑6dB. Clipping is
indicated with the red LED, which lights when the level reaches 0dB. High
resolution metering with finer resolution and more LEDs is available when
using the MCS.

The 6416m is set to be part of Control Group 1.
A mic preamp must be set to one of the four Control Groups in order to be
remote controlled using an RCI and MCS.
Use the selection button to cycle through the selections, Groups 1‑4 and
Off. Only active mic channels in the currently selected Control Group can be
edited with an MCS connected to an RCI.
When operating a Pro64 network that contains 6416m Mic Input Modules
but no RCI or MCS units, the Control Group setting has no effect.
Control Group settings are not saved as part of a Preset.
Refer to the information in the following section regarding how Presets and
Control Groups interact with and without the RCI/MCS in the network.

Mic Preamp Presets
Each 6416m Mic Input Module has the ability to save 16 mic preamp Presets.
Parameters that can be saved per channel include:
• Channel Mute status, on/off
• Phase on/off
• Low Cut Filter on/off
• Pad on/off
• +48V Phantom Power on/off
• Channel gain
Note that each channel’s network activation status cannot be saved within
a mic preamp Preset. The network Control Master manages active channels.
Furthermore, an individual 6416m Mic Input Module cannot save information
about the makeup of the Pro64 network that it was connected to at the time
the preset was stored.
Save a Preset
To save the current state of the parameters described above for all channels
of the 6416m from the front panel, press the sa v E button. The red LED in the
Save button and the one between the Enter/Cancel buttons will flash. Also,
the Edit button associated with the memory location last accessed for preset
save or recall will flash.
Select a memory location to store the Preset in by pressing one of the 16
Edit buttons on the front panel of the 6416m. Press En t E r to complete the
operation or press Ca n C E l to exit without storing a Preset.

P No t e : To save a mic preamp Preset from the MCS, remember that the
6416m needs to be set to the same Control Group as is currently
selected on the RCI that the MCS is connected to.
Recall a Preset
To recall a mic preamp Preset from the front panel of the 6416m, press the
rE C a l l button. The Recall button’s red LED, the Enter/Cancel LED, and the
Edit button corresponding to the last Preset saved/recalled will flash. Choose
the memory location that contains the desired Preset by pressing the
corresponding channel Active button. Press En t E r to complete the operation
and load the Preset, or press the Ca n C E l button to exit without recalling a
Preset.
Recalling a preset will overwrite all channel parameters as described above;
save a mic preamp Preset first if you want to recall the current settings at a
later time. When a Preset is recalled, audio is muted briefly (a few milliseconds)
while the settings are changed. This is desirable, especially when large gain
changes or changes to pad and phantom power settings are included in a
Preset.
Remember that when using the MCS Mic Control Surface to recall a mic
preamp Preset, the 6416m needs to be set to the same Control Group as
the RCI/MCS combination. Using the MCS to recall a Preset causes all 6416m
preamps in the same Control Group to recall the same‑numbered Preset
simultaneously.
Preset Rules
When saving or recalling a mic preamp Preset from the front panel of
an individual 6416m Mic Input Module, only that module is affected. For
example, to save the channel strip settings for a 64‑input system that includes
four 6416m mic modules in a network without an RCI/MCS combination, you
need to perform the save/recall operation on each module separately.
The Control Group has no bearing on the preset save/recall function when a
preset is saved or recalled from the 6416m front panel.
When an RCI Remote Control Interface and MCS Mic Control Surface are part
of a Pro64 network, the setting of the Control Group will affect the behavior
of the save/recall functions. Only modules set to the same Control Group can
be addressed from the RCI/MCS combination.
When a Preset is saved (or recalled) from the RCI/MCS combination, all
6416m modules set to the same Control Group will save or recall the same
numbered Preset simultaneously.

6416m Rear Panel Features
All 6416m rear‑panel features and functions are described in this section.
AC Power
Pro64 modules use switching power supplies that can operate at 100‑240V
and from 50‑60Hz, meaning that they can be used with most of the world’s
AC power systems by simply changing the line cord. The 6416m is equipped
with a standard grounded IEC power inlet (with fuse), which can accept the
interchangeable IEC power cord.
Fuse
The fuse holder is spring‑loaded and has space for two fuses, one main and
one spare (optional). Press the fuse holder cover to access the fuse. When
checking or replacing a fuse, always power off the Pro64 unit and remove the
line cord from the AC power source.
Always replace the fuse with one with the same rating as that being
changed.
Backup DC Power
For applications where a backup power source is required, the 6416m is
equipped with a DC power inlet using a locking 4‑pin XLR jack. A DC power
supply capable of outputting 24VDC 5% at 1.75 amps is required. In the
locking XLR plug, connect pin 1 to ground and pin 4 to the 24VDC source.
Nothing should be connected to pins 2 and 3.
1.75 AMP
PIN 1 = GND
PIN 4 = 24VDC
AC POWER
FUSE: 250VAC-F4AL
BACKUP POWER
The 6416m can be powered via its internal power supply or an optional
external 24 volt supply.
6416m DC Requirements
Like most electronic devices, the 6416m will draw more than its rated current
6416M re A r PA n e l Fe A t u r e s
56
Download from Www.Somanuals.com. All Manuals Search And Download.
for a very brief period of time at power up. This is called in‑rush current. This
also happens when powering the unit through its DC Backup power input.
A power supply connected to this input should be capable of sourcing 5A of
in‑rush current for 5ms (0.1ms rise time).
Alternately, some power supply manufacturers indicate in‑rush current
sourcing capability by specifying a maximum capacitive load. In the 6416m’s
case, a supply should be chosen that can handle a 2500μf load.
However, many power supplies have no specification concerning transient
current capability. In this case, a 100 watt (24V @ 4A) or greater, power supply
should be utilized. Although a 65 watt power supply is adequate to power
the 6416m, a 100 watt or greater power supply should be capable of meeting
the 6416m’s in‑rush current requirements.
Both internal AC and external DC power sources can be connected
simultaneously. The AC power switch controls the AC power source only.
A-Net Ports
Two EtherCon jacks are provided for A‑Net connections, labeled A and B.
Connections can use standard RJ45‑style cables or cables outfitted with
the locking EtherCon connector. Refer to the section on network modes for
Balanced Mic/Line Inputs
The sixteen female XLR mic/line input jacks on the 6416m can accept
balanced mic or line‑level audio signals. (Using line‑level sources may require
the use of the channel pad to avoid clipping.)

DB25 Audio Thru/Alternate In
Two female DB25 multipin connectors are provided for audio throughput on
the 6416m, creating a passive split of the source signals. Channels 1‑8 appear
on one DB25 jack and channels 9‑16 on the other. The DB25s are wired to the
industry accepted Tascam® compatible analog wiring standard. Do not use
DB25 cables wired for AES3 digital connections.
The DB25 Audio Thru connection allows audio signals connected to the
6416m XLR input jacks to be connected to another input device such as
a mixing console or Digital Audio Workstation (DAW) interface without
interrupting the signals connected to the Pro64 network.
Alternate Input
The DB25 Audio Thru connections can also be used as an optional main input
path. Signals connected to the DB25 connections will be metered and can be
made active on the network in the same manner as the XLR inputs.
When used in this manner, the XLR connectors would have no signals
connected to them, but could be used as a passive split output if appropriately
wired cables are provided.
For input connections, always use DB25 cables wired to analog audio
standards; never connect multipin cables wired for AES3 digital connections.
P No t e : Do not use the XLR jacks and DB25 Alternate In connections for
inputs to the same set of channels on the 6416m simultaneously.
DB25 Pinout
Breakout cables for DB25‑to‑TRS, DB25‑to‑XLR connections, etc., are readily
available. To create a custom cable for the Audio Thru/Alternate In function,
use the following table and diagram.
Note that there are several DB25 pinouts commonly in use, including two
used for AES3 digital connections. The digital pinouts are not compatible
with the analog outputs of the 6416m Audio Thru connectors. Use only those
cables wired for the Tascam analog audio pinout.

Virtual Data Cables
Three types of Virtual Data Cable (VDC) ports are available on the rear panel
of the 6416m Input Module. Fourteen VDC Slots are available system‑wide,
regardless of the current network mode (Auto or Manual). Virtual Data Cables
are not affected by the network sample rate, channel activation settings, or
gain settings.
When a module requests to activate a Virtual Data Cable, the Control Master
checks the entire network to ensure that the requested VDC is available.
Depending on the type of VDC requested, one or more VDC Slots must be
available before the request can be granted.
When a VDC Slot has a valid input assignment, the Control Master broadcasts
this information to the entire network. Each module in the network will
display the In Use LED for any valid Virtual Data Cable input.
See the VDC info elsewhere in this User Guide for help configuring and using
the fourteen available Virtual Data Cables.
Configuring a VDC
To assign a Virtual Data Cable Slot to one of the VDC ports on the 6416m rear
panel, first select an available VDC Slot using the inc/dec buttons below the
VDC Slot readout. (VDC Slots with inputs that are currently in use somewhere
in the network will have the In Use dot lit.) Use the selector button to scroll
through the choices in the Assign Port list. The control data type LED and the
Enter/Cancel LED will flash. Press the En t E r button to assign the port, or press
Ca n C E l to exit.

VDC Slot 14 on the 6416m is set to input GPIO
data from the rear-panel jack to the network.
A remote Pro64 device is set to
output GPIO data.
To output control data that originates at the 6416m from another Pro64
module elsewhere in the network, select the same numbered VDC Slot on
the remote Pro64 device that contains the data from the 6416m. Set the
remote device’s VDC type by pressing the selection button to highlight the
data type and light its LED. Press En t E r to complete the VDC assignment.
To deactivate a VDC Slot, use the selection button to scroll through the data
types until none of the LEDs is lit, and then press the En t E r button.
GPIO
GPIO (General Purpose Input/Output) can be used to send contact closure
or voltage‑type control signals through the network. Four input and four
output blocks are provided. Each terminal block can be individually wired.
GPIO inputs can be individually configured to be either Isolated or TTL.
GPIO Configuration DIP Switches
Each of the four GPIO Input blocks can be set to either Isolated or TTL
operation using the configuration switches to the left of the terminal blocks.

With the switch in the down position, the input is set to TTL. Use this setting
for voltage‑type signals. GPIO inputs set for TTL operation can handle signal
voltages up to 5 Volts.
The up position (Isolated) sets the input to accept on/off switch signals.
Do not use the Isolated setting with voltage-based signals. See the
GPIO Specifications later in this document for additional configuration
information.
GPIO Terminal Blocks
Each GPIO input or output has a positive and negative contact that can
be wired as needed. Four of each are provided. Only a small screwdriver is
required.
MIDI In, MIDI Out
Two MIDI (Musical Instrument Digital Interface) ports, In and Out, are provided
on the 6416m. Each is capable of transferring any type of MIDI‑compatible
data. Pro64 devices do not process or filter MIDI data in any way.
VIRTUAL DATA CABLE PORTS

Both MIDI ports in the VDC section can be used simultaneously.
One MIDI In per Pro64 device can be assigned to a VDC Slot. An unlimited
number of Pro64 modules can make use of the MIDI data by assigning MIDI
Out to the VDC Slot with the same number as the input source.
RS-232 Port
The Pro64 RS‑232 VDC ports allow a pair of devices to transfer control data
at rates up to 57.6k baud across the Pro64 network. Using Virtual Data Cables
for RS‑232 always requires two VDCs because RS‑232 data transfers require
communicating devices to be set up in a handshaking pair. Note that RS‑232
communication is point‑to‑point, meaning that a maximum of seven RS‑232
sessions (14 total devices) are possible when using Pro64 Virtual Data Cables.

RCI Front Panel Features
The RCI provides a network access point for remote control of the 6416m.
Any number of RCI Remote Control Interfaces can be installed anywhere in
a Pro64 network, providing multiple control access and monitor points. The
Control Group function on the 6416m and RCI allows control of active mic
channels to be divided among up to four different simultaneous users and
control points. The RCI can also be used simultaneously with m‑control for
Yamaha digital console to provide multiple points of control.
The RCI can also be used as a stand‑alone monitor station; any Pro64 network
audio resource can be selected (from the RCI or MCS) and monitored using
the built‑in headphone and/or line‑level XLR mono outputs. MCS Mic Control
Surfaces can be connected and disconnected from the RCI without affecting
network behavior.
This section describes the features and functions of all front‑panel
components of the RCI Remote Control Interface.
Headphone Input Jack
The 1/4‑inch TRS headphone input jack accepts any stereo headphone or
earphone. The mono audio signal monitored here is determined by the
currently selected A‑Net Slot as shown on the RCI front panel. The selected
A‑Net Slot being monitored is always available at both the headphone jack
and the rear‑panel XLR line‑level output. Only one Slot can be monitored at a
time; the headphone jack always monitors a mono signal.
Monitor Volume Control
This knob controls the volume for the headphone jack and has no effect on
the fixed level of the rear‑panel line‑level monitor output.
Network Mode Selection
The Network Mode section of the interface has a set of LEDs that indicate
the current network mode being used: Auto or Manual Mode. The current
network mode is set at the Control Master. In Auto Mode, no network settings
are available, the Pro64 network manages all channel allocation and VDC
resources. It does not matter which rear‑panel A‑Net port is used to connect
the RCI to the network.
In Manual Mode, the user can select a specific A‑Net port from which to draw
channel information.

A-Net Slot
The A‑Net Slot display shows the network Slot that is currently available to
be monitored by the headphone and rear‑panel XLR outputs. Any active
network Slot can be monitored, even if its content is not coming from a
microphone input module.
The display will scroll sequentially through all available Slots (as determined
by the current network sample rate) with two variations: double dashes with
and without the Sync dot on.
The display will show a double dash (––) when no Slot is selected. No audio is
monitored at the headphone and XLR outputs in this case.
The display will show a double dash with a dot (––.) to indicate that the RCI
Slot to be monitored is selected remotely from the MCS Mic Control Surface.
The display will reflect the Slot being monitored plus the dot when Slots are
selected from the MCS. The RCI and MCS will remain in sync until the user
selects a channel directly from the RCI front panel.
Inc/Dec Slot Selection
Use the inc/dec button below the numeric Slot display to select an active
Slot to be monitored.
Selecting a Slot directly from the front panel of the RCI while the RCI and
MCS are in sync causes the synced operation to stop.

The dot in the Slot Selection display is used to indicate that Slot selection is
being controlled from the MCS Mic Control Surface. Slot selection will remain
in sync until the user selects a Slot directly from the RCI front panel.
To activate the sync function and allow Slot selection to be controlled from
the MCS Mic Control Surface, use the inc/dec buttons on the RCI to scroll
until “‑‑.” (double dash with a dot) is shown in the display. At this point, sync
is activated and the MCS has control of Slot selections. Slot numbers recalled
from the MCS will be reflected on the RCI display and that Slot’s audio will be
output to both the headphone and XLR connectors for monitoring.
Control Group Selection
Each 6416m Mic Input Module in a Pro64 network can be set to one of four
Control Groups. This allows multiple zones of mic modules to be controlled
by different users if desired.
CONTROL
Group 2
Group 3
Group 4
Control Group selection
A mic preamp must be set to one of the four Control Groups in order to be
controlled by an MCS. An RCI must also be set to the same Control Group as
the mic preamp you wish to control.
Use the selection button to cycle through the selections, Groups 1‑4 and Off.
Setting an RCI or 6416m Control Group to the Off state will stop it from being
accidentally changed or edited by any remote device. (Its front panel still can
be edited locally, however.)
Only mic channels in the currently selected Control Group can be edited with
an MCS Mic Control Surface connected to an RCI.
A-Net LED
The blue LED found within the A‑Net logo of the RCI functions as the network
activity indicator. When a module is powered up, its A‑Net LED will flash
while a request to enter the network is sent to and then processed by the
rci Fr o n t PA n e l Fe A t u r e s

device designated as Control Master. Once a module is enumerated and is
part of the Pro64 network, the blue A‑Net LED will light solid. The LED will
remain lit as long as valid A‑Net network data is received.
The A‑Net LED will flash during a firmware update when the module being
updated is part of an active network. When a module is being bench
configured (it is not part of an active network), the A‑Net LED will be off
during the firmware update. (Check the Aviom website for current firmware
updates.)
Controller Input for MCS
Plug the optional MCS Mic Control Interface into the Controller port on any
RCI in the network to monitor and edit active channels on mic modules set to
the currently selected Control Group.
The Controller input sends bidirectional data plus power to the connected
MCS Mic Control Surface.
Do not plug Pro64 A-Net signals into the Controller Input port.

and from 50‑60Hz, meaning that they can be used with most of the world’s
AC power systems by simply changing the line cord. The RCI is equipped
with a standard grounded IEC power inlet (with fuse), which can accept the
interchangeable IEC power cord.
Fuse
The fuse holder is spring‑loaded and has space for two fuses, one main and
one spare (optional). Press the fuse holder cover to access the fuse. When
checking or replacing a fuse, always power off the Pro64 unit and remove the
line cord from the AC power source.
Always replace the fuse with one of the same rating as that being changed.
Backup DC Power
For applications where a backup power source is required, the RCI is
equipped with a backup DC power inlet using a locking 4‑pin XLR jack. A DC
power supply capable of outputting 24VDC 5% at 0.75 amp is required. In
the locking XLR plug, connect pin 1 to ground and pin 4 to the 24VDC supply.
Nothing should be connected to pins 2 and 3.
BACKUP POWER
AC POWER
0.75 AMP
PIN 1 = GND
PIN 4 = 24VDC
FUSE: 250VAC-F4AL
The RCI can be powered via its internal power supply or an optional external
24 volt supply.
Both internal AC and external DC power sources can be connected
simultaneously. The AC Power switch only controls the AC inlet.

MCS Features
The MCS is used to edit 6416m mic preamp settings and save/recall presets
remotely. A single MCS connected to an RCI can be used to control up to 64
channels of 6416m input channels, regardless of their location in the Pro64
network. Multiple control points can be provided by installing more than one
RCI Remote Control Interface in a Pro64 network.
All changes made from the MCS are immediately reflected on the front panel of
all 6416m modules in the same Control Group. The MCS can be disconnected
from the network as needed without affecting network behavior. Its features
are described in detail below.
Channel Level Meters
The MCS has 64 channel level meters that use bicolored LEDs. Green LEDs are
used for normal signal levels and red is used to indicate channel clipping.
The MCS will show the current level of all active network channels regardless
of whether the channel is a microphone signal or not.
Numeric Keypad
The numeric keypad can be used to select an active Slot for monitoring or
editing and is also used to select a mic pre Preset for save/recall.
You can enter a single digit for numbers below 10 or enter a leading zero (02,
07, etc.).
If you make a mistake when entering a Slot number, you can continue to enter
numbers any time prior to pressing the En t E r button. The interface will move
digits to the left in the numeric display as they are entered. For example,
entering 4, 2, 3, 7, En t E r will recall Slot 37, the last two digits entered.
When saving or recalling a mic pre Preset, only numbers from 1 to 16 are valid.
Inc/Dec Selection Buttons
The two arrow buttons in the numeric keypad area are used for inc/dec or
up/down functions when selecting Slots and Presets.
To select a Slot, press inc or dec to scroll sequentially through the available
Slots (the exact numbers displayed will be determined by the current
network sample rate). Follow the selection rules above; press En t E r or simply
wait for the Slot to be automatically selected. Press Ca n C E l to return to the

Building a Pro64 Network
Configuring a Pro64 network involves connecting input and output modules
with Cat‑5e cables, setting A‑Net Slot ranges, and activating input channels.
Any number of 6416m Mic Input Modules and RCI remote Control Interfaces
can be connected and located anywhere in a Pro64 network.
Choosing a Network Mode
When designing a network, deciding which network mode to use—Auto
or Manual—can be made simpler by assessing the total audio channel
requirements for an application at a given sample rate first.
If you want to build a 48kHz network, for example, that requires no more than
64 total audio channels, choose Auto Mode; this is the easiest to implement.
The network takes care of most of the management tasks automatically.
If the network is larger than 64 channels at 48kHz—for example, a 56x16
digital snake for a live stage to front‑of‑house application—choose Manual
Mode. Pro64’s Manual Mode offers the most flexibility but requires more
care when connecting modules and configuring input and output routing.
Connecting Pro64 Modules
Start by setting one (and only one) device to be the network Control Master.
Because there are some operations that can only be executed at the Control
Master, be sure that the module designated as the Control Master is accessible.
Once all modules in the network are enumerated (indicated by illuminated
A‑Net LEDs), choose a network mode (Auto/Manual), set A‑Net Slot ranges
on each module, and activate audio channels and VDCs as needed.
When adding input modules to an existing audio network running in Manual
Mode, it is best to add modules that are not pre‑configured with active
channels and/or VDC Slots in use to avoid unwanted overwriting of A‑Net
Slots. Pro64 output modules’ audio settings do not cause conflicts with the
configuration of audio input resources but its VDC settings can impact the
network.
Basic Routing
To output the mic/line audio inputs connected to the 6416m, the module
must be connected to another Pro64 device somewhere in the network that
can output its data. This Pro64 device can be a standalone analog or digital
module or a console interface card such as the 6416Y2 console card for use in
Yamaha® digital products supporting the MY expansion card format.

The diagrams that follow use generic input and output module icons. Any
Pro64 I/O device can be substituted unless otherwise noted. Connect the RCI
at any convenient location in the diagrams that follow to provide a monitor
station and remote control of 6416m mic preamp parameters.
Auto Mode Connections
In Auto Mode, the 6416m’s A‑Net ports on the rear panel can be connected
to other Pro64 devices interchangeably. In the following examples, network
performance and functionality are unaffected by the changes in cabling.
Example 1: Port A connected to Port B
Input
B
A
Output
B
A
The A-Net cable can be connected to either Port A or Port B. Reversing the
A-Net connections causes the same results. Either port can be used to
expand the network.
Up to 16 inputs can be activated on the 6416m Mic Input Module. Other
Pro64 devices can be connected using either Port A or Port B to expand the
network. In both cases, the active channels will be available at the output
module.
Remember that the entire 64‑channel A‑Net stream (at 48kHz) is always
received and transmitted through every Pro64 module. The A‑Net Slot
Transmit or Receive settings simply tune a module in to a specific range of
Slots within the network.
When using remote control via the RCI and MCS, the RCI can be connected to
any open A‑Net port.

In this diagram, note that additional Pro64 modules can be connected to any
available port as indicated by the dotted line.
Here, Port B of the input module is connected to Port A of the output
module, the opposite of Example 1. The same results can be achieved by
connecting Port A on the input module to Port A on the output module and
by connecting Port B on the input module to Port B on the output module.
Since the network is operating in Auto Mode, all A‑Net ports carry the full
bandwidth of the network. There is no “input” or “output” A‑Net port on I/O
modules or hubs.
Digital Copies in Auto Mode
Any number of digital copies (also referred to as digital splits) can be created
by simply connecting additional Pro64 output devices and setting them
to the same A‑Net Slot range. In Auto Mode, the order and location of the
modules in the network does not matter; output modules can be connected
before or after any input module. Optionally, Pro64 modules can be
connected in parallel using a Pro64 merger hub such as the MH10 or MH10f.

In this example, note that the A-Net connections between devices can be
any combination of the A and B ports. Any open port can be used to connect
additional Pro64 devices.
The order of the Pro64 modules connected in series in Example 3 above can
be changed without affecting the ability of the network to distribute the
same incoming audio channels to all three output modules shown. A‑Net
ports always transmit and receive the entire network (audio and VDC data)
at all times.
The rules are the same when larger networks are created. Simply set a
different A‑Net base Slot on the I/O modules to use more A‑Net Slots as
needed. Cables can be connected to any available A‑Net port, A or B.
Remember that in Auto Mode that the maximum number of active channels
at 48kHz will be 64. I/O modules can be mic, line, digital, or console cards as
needed.
Adding a Merger Hub in Auto Mode
For more wiring options, an A‑Net Merger Hub such as the MH10 or fiber‑
capable MH10f can be added to a network. Using a merger hub enables
parallel connection of A‑Net devices. Multiple merger hubs can be used
to simplify gear rack wiring and distribution of digital signals amongst the
various subsections of a digital audio network.
P No t e : Standard Ethernet networking products are not compatible with
Pro64 products. Use only A‑Net compatible devices.

In Auto Mode, modules can be connected to any port on the MH10.
Note that in the example, it does not matter which A‑Net port (A or B) on the
I/O modules is connected to the MH10. Likewise, on the MH10, the choice of
A‑Net port (1 through 10) does not matter. Any audio channel made active
on the input module in the diagram will be available to all output modules.
Remember that the modules shown in the diagrams can be analog, digital,
or console interface cards as needed. Likewise, the RCI can be connected to
any available port to add remote control capabilities.
Manual Mode Connections
When creating bidirectional networks that require more than 64 channels
(at 48kHz), Manual Mode is the answer. Unlike Auto Mode, Manual Mode
requires that the user pay attention to which A‑Net port (A or B) is used
when connecting network cables to each module. As implemented in the
Pro64 Series of products, A‑Net is a truly bidirectional stream of up to 64x64
channels at all times.
In the examples that follow, the diagrams will indicate the specific A‑Net port
on an I/O module that is in use. Input modules such as the 6416m can send
active audio channels to Port A, Port B, or both Ports A and B.

The input module transmits its audio data via Port A (marked with a square
surrounding the port name). Only the lower Pro64 output module can make
use of those audio channels.
In the example above, showing I/O modules in the middle of a Pro64
network, the input module in the center of the diagram is set to transmit
its active audio data to Port A, using the A‑Net Slot range starting at 1. The
output module below it is set to listen to any A‑Net data that arrives on its
Port B. The output module at the top of the diagram is set to listen to data
arriving at its Port A.
Since the input module is directing its data to Port A, only the bottom
module can output the audio channels made active on the input module.
Again, the example assumes that all modules are set to the same A‑Net Slot
range. Remember that all network audio is always transmitted and received
at each A‑Net port. The module’s Slot Range selection simply tunes into a
specific range of channels.
A‑Net merger hubs can be added as need to simplify cabling, extend the
distance between Pro64 modules, and to provide split points and redundant
cable paths.
Remember that when using Manual Mode the RCI Remote Control Interface
also needs to have its A‑Net Receive ports set properly in order to edit
channel strip parameters of 6416m modules in the Pro64 network.

The next example refines this drawing by adding specific locations for the

Digital Copies in Manual Mode
Creating a digital split in Manual Mode follows most of the rules defined
for Auto Mode splits. Any output module connected in series to an existing
output module can output the same audio as long as the A‑Net Slot range
and A‑Net Receive Port settings are configured properly, and as long as no
other input modules overwrite the audio.

front of house. Unlike Auto Mode, however, this input module needs to be
set to send audio data to its A‑Net Port B in order to make the digital split
work.
The example assumes that all modules are set to the same A‑Net Slot range.
By setting the FOH input module to transmit its A‑Net data to Port A and B,
the A‑Net data flows in two directions: to the output module on stage and
to the output module in the recording area. Both output modules are set to
receive A‑Net data via Port A.
Digital audio arriving at the front of house location from the stage is replaced
with the content generated by the FOH engineer that is connected to the
Pro64 input module at FOH when those same Slots are transmitted to the
recording area via the same Slot range.
To send the stage audio to the recording system instead, set the input
module at front of house to transmit its data on Port A only. By doing this, the
audio from the stage flows through all the modules to the recording system.
Remember that A‑Net merger hubs such as the MH10/MH10f can be added
as needed to simplify cabling, extend the distance between Pro64 modules,
and to provide split points and redundant cable paths.

VDC Configuration
Pro64’s Virtual Data Cables provide an easy way to distribute control
signals throughout a network, greatly expanding the possibilities for using
and distributing MIDI, GPIO, and RS‑232/422 control signals. (Not all Pro64
modules have the same VDC complement.)
A‑Net provides the ability to send these control data over greater distances
than previously possible with traditional analog connections. And with MIDI
and GPIO connections, infinite numbers of copies of the control data are
available everywhere in the network.
Fourteen VDC Slots are available at all times; VDCs are not affected by the
current sample rate or network mode. The makeup of the VDC Slots is user
defined; no VDC Slots are reserved for specific data types.
The VDC interface includes the numeric VDC Slot display, the inc/dec buttons
used for VDC Slot selection, the Assign Port list of VDC data types, and a
selection button for choosing a VDC data type for the currently selected VDC
Slot.

VDC Slot Display
The two‑digit VDC Slot display shows the currently selected VDC Slot (1
through 14). The In Use LED within the display indicates that a selected
VDC Slot has an active input somewhere in the network. If only an output is
assigned to a particular VDC, its In Use LED will not be lit.

When a rear-panel VDC port has been assigned to a VDC Slot, its In Use
LED will be on.
Selecting a VDC Slot is done with the inc/dec buttons below the display.
Pressing the inc/dec buttons will cause the display to scroll up or down, and
will wrap at the end of the numeric list.
As the VDC Slots are displayed, any VDC Slot with an active input will light
the In Use LED. If the In Use LED is not lit for a selected VDC Slot, no input is
assigned to that VDC Slot and all of the VDC type LEDs in the Assign Port list
will be unlit when the VDC out has been assigned locally.
The available VDC data types for the 6416m are:
• RS‑232
• MIDI In
• MIDI Out
• GPIO In
• GPIO Out
VDC In Use LED
The VDC In Use LED serves to indicate that a Virtual Data Cable Slot has a
current active input assignment. Output assignments for MIDI Out or GPIO
Out will not light the In Use LED.
The In Use LED will light whenever a valid assignment (GPIO In, MIDI In, or
RS‑232) has been made anywhere in the network. The VDC Slot can only be
used for the assigned data type until it has been deactivated at the point in
the network where the input source has been assigned.

Assigning a VDC Slot
The act of assigning a VDC Slot maps one of the rear‑panel hardware VDC I/O
ports to a Virtual Data Cable. To assign a VDC port to a VDC Slot, two actions
are required. First an available VDC Slot must be selected, and second, one
of the VDC data types from the Assign Port list must be assigned to that VDC
Slot.
To select a VDC Slot to activate, scroll through the list to a numbered location
that does not have the In Use LED lit.
To assign a data type, use the selector button below the Assign Port list to
select the desired VDC data type, for example MIDI In. The LED next to the
selected type will light; the Enter/Cancel LED will also start to flash. Press
En t E r to enable the VDC Slot; press Ca n C E l to exit without assigning a VDC
port.
To output VDC data from the network to a rear‑panel VDC port, choose a VDC
Slot with the appropriate data type for the application (for example, MIDI).
Active network VDC Slots are displayed with the In Use LED on.
Once selected and configured, the rear‑panel I/O connection for the selected
VDC can be used to transfer control signals.
Deactivate an Active VDC Slot
To release an active input assigned to a VDC Slot, use the inc/dec button
to scroll to the active VDC Slot. (Its In Use LED should be on.) Press the
selector button below the Assign Port LEDs until no VDC data type LED is
lit. The Enter/Cancel LED will be flashing. Press En t E r to deactivate the VDC
Slot assignment and make that VDC Slot available to other modules in the
network.
P No t e : Only VDC inputs need to be deactivated to free Virtual Data Cable
resources. VDC outputs do not reserve any of the fourteen Virtual
Data Cable resources.

exit.
Set a New Password
Each Pro64 module can store a four‑number network password. However,
the password lock/unlock feature can only be used from the network Control
Master. Passwords can be changed only when the network is unlocked.
The password is a four‑number sequence created using the numbered
channel activation buttons 1‑16 on the front panel. Passwords can include
repeated numbers (such as the default factory‑supplied password of 1‑1‑1‑1).
When creating a password, any string of numbers can be used, but note that
only the last four button presses are stored.
To set a new password, press Fu n C t i o n and then the C h a n n E l 10 aC t i v E button.
Key in a four‑number button sequence and then press En t E r . The channel

Sample Alignment
All digital networks that allow daisy‑chained connectivity need to
compensate for sub‑millisecond latency build‑up between devices when
data is retransmitted. In the majority of cases, there is no audible effect (as
the individual delays are very small), but without compensation, these small
variations in latency can become an issue in certain applications as the
network grows in size.
On power up, each device in the network will calculate a sample alignment
value based on the current sample rate and will apply it as long as the
network is running. The next time the network sample rate is changed or the
system is power cycled, a new value will be calculated and locked in. This
sample alignment value will be referred to as the default value in the text that
follows. Using the default value will offer the simplest method of operation.
However, to guarantee repeatable latency down to the microsecond, the
user has the option of measuring the sample alignment amount for a given
sample rate and then applying that measured value every time the network
is powered up. This is referred to as a stored value in the text that follows. By
using these stored values, the Pro64’s unique software guarantees consistent
delays between each component of the network.
Sample Alignment Status
The sample alignment query, Function 11, can be performed on the Control
Master or any remote unit in the network. The network can use the default
value (created at the time of power‑up) or a stored value.

C h a n n E l 11 aC t i v E button. Press En t E r ; the A‑Net Slot display is used to
indicate the current value in use.
• The A‑Net Slot display reads “0” to indicate that the system’s
default values are being used. (This is set with Function
14.)
• The A‑Net Slot display reads “1” to indicate that stored
values are being used. (This is set with Function 13.)
Measure New Sample Alignment Value
To generate a new sample alignment value, use Function 12. This Function
can only be performed at the Control Master when the network is unlocked.
Press the Fu n C t i o n button, followed by C h a n n E l 12 aC t i v E button. The sixteen
channel meter LEDs and the Enter/Cancel LED will flash, indicating that this
operation will replace the currently stored value. Press En t E r to measure
and generate a new sample alignment value, or press Ca n C E l to exit without
updating the stored value. A forward sweep of the level LEDs indicates that
the function is complete.
Values are stored in each module’s memory but are not put into use until
Function 13 (Use Stored Sample Alignment Values) is performed, which
activates the stored sample alignment values. The module must be the
network Control Master to use its stored value. Use Function 11 to get info on
the current values in use.
When the stored sample alignment value is being used, a new sample
alignment value should be calculated each time the network sample rate is
changed, or when the system configuration changes. (Changes include the
addition/subtraction of Pro64 modules, different wiring schemes, etc.)
Use Stored Sample Alignment Value
When a new sample alignment value has been generated and stored,
Function 13 can be used to activate and lock in this value for use throughout
the network. This Function can only be performed at the Control Master
when the network is unlocked.
To use the stored value, press the Fu n C t i o n button, followed by the C h a n n E l
13 a C t i v E button. The Enter/Cancel LED and the sixteen yellow channel meter
LEDs will flash. Press En t E r to use the stored value, or press Ca n C E l to exit
without changing the sample alignment value (the system reverts to using
the default value).
The stored sample alignment value remains in force even when the network
is power cycled. When the network is reconfigured or when the sample rate
is changed, a new value should be calculated using Function 12 described
above.

default value. (Function 13 is used to instruct the system to use a stored
value. )
To set the network to use the default sample alignment value, press Fu n C t i o n ,
followed by the C h a n n E l 14 a C t i v E button. The sixteen channel meter LEDs
and the Enter/Cancel LED will flash. Press En t E r to use the default value, or
press Ca n C E l to exit without changing the current value. A forward sweep of
the level LEDs indicates that the function is complete.
Use Function 11 (Get Sample Alignment Info) to display the current value in
use—default or stored.

Firmware Update
Pro64 modules can be updated in the field using a PC and the Pro64 Update
Tool application. Modules can be updated over A‑Net, while part of an active
audio network, or in local mode where no other modules are connected at
the time the update is being performed (such as may be required for a bench
configuration when setting up modules prior to installation).
Updating a module requires the Aviom Pro64 Update Tool application, a PC
host computer with RS‑232 connection capability, a null modem DB9 cable,
and the update file for the particular Pro64 device being updated. Refer to the
Aviom website for information about the availability of the latest firmware
Update Connections
To update modules via A‑Net, a host computer is connected to the network’s
Control Master via the RS‑232 port in the Virtual Data Cable section of the
rear panel. Individual modules are then selected and updated from within
the Pro64 Update Tool. Updates can be applied to the Control Master or a
slave device.
To update via A‑Net, make sure that no RS‑232/422 or MIDI VDC resources are
configured on the Control Master. (Refer to the Virtual Data Cable information
elsewhere in this document.) Then, enter Managed Mode by pressing the
Ma n a g E d button on the Control Master.
To update modules locally, the computer is connected directly to the module
being updated, via the RS‑232 port as described above. The Pro64 Update
Tool application must also be set to its local update mode. (See the Pro64
Update Tool Help file for more information.)
Baud rates for data transfer must be set the same on the Pro64 device and PC
host running the Pro64 Update Tool. Refer to the VDC RS‑232 baud rate info
elsewhere in this document to learn how to set the baud rate parameters. On
the Pro64 module, RS‑232 must be configured for 8 data bits, no parity, and
one stop bit. Also, refer to the firmware update instructions that come with
the Pro64 update application for additional information on setting up the PC
host.
Firmware Update - Local
Function 15 enables a Pro64 module to receive new firmware from a host PC
connected to the RS‑232 port on the module’s rear panel. Updates can be
applied to a Pro64 module set to be a Control Master or slave device.
To enable firmware updates on the module, press Fu n C t i o n , followed by
the C h a n n E l 15 aC t i v E button. The Enter/Cancel LED and the channel level

LEDs will flash to indicate that this function will interrupt normal network
operation. Press En t E r to enable the module to receive new firmware from
the PC host. Send the firmware update following the instructions that came
with the Pro64 Update Tool. During the update the sixteen red, yellow and
green channel meter LEDs will flash in sequence.
When the firmware update has been sent successfully, the module will
reset and normal front panel operation will be restored. If for some reason
the firmware update fails, refer to the error recovery information below for
instructions on how to recover and complete the update.
When a module is being updated locally, the dot in the VDC Slot display will
be on, indicating that a local firmware update is in progress.
When a module is waiting for a firmware update to begin, you can exit the
firmware update state by pressing the Ca n C E l button. If the firmware update
has not yet started, the module will attempt to reset, returning it to normal
operation.
P No t e : Do not press the Ca n C E l button while a firmware update is in
progress.
Error Recovery
In case of a partial firmware download or interruption to the firmware
transfer (as would happen because of a power failure, computer crash, or by
pressing the Cancel button in the middle of a firmware update), the module
can still be updated but will need to be powered up directly into the firmware
load mode. To do this, hold the VDC Slot decrement (down arrow) button
while powering up the unit. Then send the firmware from the computer as
described previously.
Firmware Update - via A-Net
To enable a Pro64 module to receive new firmware via A‑Net on an active
network, the PC must be connected to the RS‑232 port on the Control Master.
The network must be in Managed Mode to update firmware via A‑Net. All
network audio will be muted, and front‑panel functions will be disabled on
the module being updated.
To enable firmware updates, a module must be selected from within the
Pro64 Update Tool application, at which point it will be set up to receive
new firmware. Send the firmware update following the instructions that
came with the update firmware. During the update, the module’s sixteen
red, yellow, and green channel meter LEDs will flash in sequence. When the
firmware update has been sent successfully, the module will reset and audio
will be restored.

Mounting the MCS
The underside of the MCS has two keyhole openings that allow the MCS to
be attached to another surface using only two screws (not included). The
diagram below shows the size and location of the two keyhole openings.

MIDI/GPIO Cable Lengths
To meet the EN55103‑2 (Electromagnetic Susceptibility/Immunity)
Specification, any cables connected to the MIDI and/or GPIO ports
must not exceed three meters in length. Use of cables longer than three
meters will not guarantee equipment conformance to EN55103‑2.

DB25 Audio Connections
Aviom analog input and output modules with DB25 multi‑pin connectors are
wired to the analog pinout that has become standard in the audio industry
(which is sometimes referred to as the Tascam® DA‑88 or DTRS pinout). This
wiring standard allows easy interfacing with a variety of audio equipment
using readily‑available multi‑pin breakout cables or by incorporating Aviom’s
PB28 Modular Patch Bay products. Each DB25 jack on an Aviom product
carries eight balanced audio channels.
Note that digital devices that transmit AES3 digital audio data (sometimes
referred to as AES/EBU) use a different wiring pinout; analog and digital
multi‑pin breakout cables and/or patch bays are not interchangeable.
Wiring an Analog DB25 Cable
To wire a custom cable for use with the analog DB25 jacks on an Aviom
product, use the following table:

Using DB25 Jacks
The DB25 panel‑mount connectors on Aviom products have #4‑40 UNC
threads. Be sure to get DB25 breakout cables with the correct thread type;
forcing the connectors by using the wrong thread type will strip one or more
of the mating components rendering them unusable.
Strain relief is suggested when using DB25 cable assemblies. DB25 breakout
cables should always be supported when connected to an Aviom product to
reduce the risk of damaging the product’s rear panel.
