CHAPTER 1: Introduction  
Product overview  
Congratulations on purchasing the XAP 800, a highly advanced twelve-by-twelve  
digital matrix mixer with Gentner® Distributed Echo Cancellation®, noise  
cancellation, and audio processing. It uses an internal macro language and 32 user-  
definable presets to quickly adapt to a variety of teleconferencing and sound  
reinforcement applications such as distance learning, teletraining, telemedicine,  
courtrooms, conference rooms, boardrooms, hotels, and houses of worship.  
In its most simple form, the XAP 800 is a mic mixing matrix. As such, all mic  
mixing parameters can be customized and any input or combination of inputs can  
be routed to any output or combination of outputs, with attenuation adjustments at  
each cross point.This allows great flexibility in accommodating a variety of  
applications and requirements.  
The XAP 800 features numerous functions which greatly enhance its  
performance and flexibility. For example, it can gate mics on and off when the  
sound within a mic’s acceptance pattern reaches a certain level.  
The XAP 800 monitors each mic independently, observing ambient levels and  
making decisions based on each mic’s environment.Thus, the input for a mic  
located in a highly reverberant part of a conference room is gated, mixed, and  
processed to compensate for the changes in that area and reduce echo and noise.  
This improves audio quality and decreases the possibility of feedback.  
The XAP 800 facilitates local and remote PC setup and diagnostics, logic  
outputs, and automatic gated mic operation. Mic inputs can be individually  
customized to gate on and off as you want, while automatic gain control keeps the  
overall sound level consistent. Eight of the 12 channels can be configured as an  
automatic microphone mixer.  
Adjustments in routing, level, and other functions can be made through presets  
activated through a closure on the rear panel, an RS-232 serial interface, or a  
control panel on the expansion bus data channel.  
The XAP 800 features eight audio processing blocks, each with 15 filters.  
Each filter can be configured as a parametric equalizer, high pass, low pass, CD  
horn, high shelving, low shelving, all pass, or crossover.This allows you to tailor the  
XAP 800’s audio response to optimize the audio quality and fidelity characteristics  
of a wide variety of sound reinforcement systems.

Introduction ~ New Features  
2
The GPIO (general purpose input/output) allows switching among any of 32  
user-stored presets.This gives you real-time flexibility to meet a variety of  
reinforcement requirements.  
Network-based interconnectivity allows up to eight XAP 800s and XAP 400s  
to be connected and controlled as a single unit, allowing microphone coverage in  
applications requiring up to 64 mics.  
The XAP 800’s Macro Pro™ scripting language allows the unit to function  
without the need for an external controller. However, it can be easily interfaced to  
an external controller via either of the two RS-485 ports.The unit can also  
interface with a PC through the RS-232 port.  
New Features  
Virtual references. The XAP 800 now supports echo cancellation summing.  
Four user-definable virtual references are provided which can use multiple  
signals as the echo cancellation reference point without sacrificing an analog  
output.This added flexibility further enhances echo cancellation performance.  
Improved noise cancellation. Our industry-leading noise cancellation keeps  
background noise to a minimum while retaining top-level voice quality, echo  
cancellation performance, and full-duplex capability.  
Front panel gain and mute control. Now gain and mute adjustments can  
be made from the front panel. Using these controls allows you to make quick  
volume and mute changes without connecting through G-Ware.  
Safety Mute. The new Safety Mute button on the main G-Ware toolbar  
allows you to mute all outputs with one simple click if feedback or audio  
problems occur during the configuration process.  
Preset and Macro Passwords. You can now password protect your presets  
and macros to prevent unauthorized changes.  
Clear Matrix. This new button on the Matrix Screen makes it easy to clear all  
cross point cells in the matrix. Simply click the button and confirm the action.  
RAMP serial command. The new RAMP serial command (see page 123)  
gives you greater control over gain adjustments.You can specify the rate at  
which the gain increases and decreases as well as the target level.

Power is supplied through the RS-485 ports to the remote Control Panels  
from the XAP 800.This power is limited to a total of 300mA at 15 volts for  
each connector. Over-current protection is provided on the +15V pins to  
prevent damage in the event of shorting. External power can be provided to  
control devices when more current is required. See page 92 for maximum  
cable run distances when using ClearOne Control Panels.  
D. Control/Status Ports A and B.These two female DB25 connector are used  
to connect control devices to the XAP 800.The control devices have access  
to the command set for the XAP 800 and can be used for common functions  
such as volume control, muting, preset change, room combining, etc. Devices  
can be connected to either port.  
For instructions on how to program the control and status pins, see the  
GPIO section on page 77.The default settings allow control and status of  
inputs, outputs, volume, and presets.These pins are active low.The 32 presets  
can also be activated via these connectors. For pinout and default  
information, see Appendix B.  
E. Outputs 1–12. These three-pin Phoenix connectors are for connection of  
twelve line-level balanced outputs with three-pin Phoenix connectors.These  
outputs are typically used for connection to VCRs, tape recorders, amplifiers,  
codecs, phone hybrids, and other audio devices.These outputs may be  
configured to contain any combination of gated and non-gated inputs.The  
nominal output level is 0dBm.  
F. Inputs 9–12. These Phoenix connectors are for connection of up to four  
line-level inputs.These are typically used for connection of VCRs, tape  
players, CD players, and other audio sources.They can be routed to any  
output or multiple outputs. Nominal level is 0dBu.  
G. Expansion Bus In/Out. This RJ-45 connector is part of the expansion bus  
(E-bus), which allows up to eight XAP 800 or XAP 400 units and up to 16  
XAP TH2 units to be networked together.The E-bus consists of two buses:  
one for control, the other for passing audio and mic information (see Control  
bus, page 7). Using Cat 5 twisted-pair cable, you can separate adjoining units  
up to 80 feet (24 meters). See the diagram on page 11.  
I. RS-232. This female DB9 serial port is for interconnection between the XAP  
800 and a PC, modem, or other custom remote controller. For serial  
protocol, see Appendix B: Connector Pinouts.

Networking  
Expansion bus  
The latency or propagation  
delay is <1ms.  
The digital mix-minus expansion bus (RJ-45 LAN) is used to connect up to eight  
XAP 800/400s and 16 XAP TH2 units, where the total number of microphone inputs  
does not exceed 64.The maximum distance between interconnected XAP 800/400 or  
PSR1212 units is 80 feet (24 meters). Connecting a XAP TH2 must not increase the  
cable length between two PSR1212s, XAP 800s and/or XAP 400s beyond 80 feet.  
ClearOne recommends that category five twisted-pair (10BaseT LAN) cable be used.  
The expansion bus (E-bus) allows audio routing between destinations on the  
E-bus network.The E-bus contains 12 independent digital audio buses labeled O–Z  
which can route mic or line level inputs in any combination across the E-bus  
network.The O–Z buses are divided into two groups (O–R and S–Z) based on their  
capabilities and default settings.The E-bus also contains four PA adapt/acoustic  
echo cancellation reference buses, four global gating buses, and one control bus.  
O–R buses. These four audio buses are defaulted as the mic mix buses; they  
can communicate the NOM count and mic mixing parameters across the  
network to other XAP 800s. All gated mics are routed to the 0 bus by default.  
S–Z buses. These eight buses are defaulted as auxiliary mix buses.They are  
used to route auxiliary audio, such as from a CD player or VCR, to and from  
other units on the network.These buses are also used as mic mix buses when  
NOM count is not required.  
PA Adapt/Acoustic Echo Cancellation Reference buses. These buses  
allow an input from a XAP 800 to reference an output on another linked  
XAP 400/800. See PA Adapt and AEC Reference on page 33 for more  
information.  
Global Gating Groups A–D buses. These mix-minus buses are defined as  
microphone gating groups which support first-mic priority, maximum number  
of mics, etc. and work across all linked XAP 400/800s. Unlike the audio  
buses, they contain only mic status and gate parameters. See page 41 for  
more information about gating groups.  
Control bus. The control bus is an independent channel from the E-bus’s  
audio channel; it uses a different pair of wires on the same E-bus cable.This  
allows control information to pass even if the units are not using the audio  
link.The XAP 800 supports the full set of commands through the control bus.

CHAPTER 2: Installation  
The XAP 800 is designed for easy installation and setup. All connections are made  
through rear-panel connectors.This chapter provides instructions on making  
hardware connections, creating an expansion bus (E-bus) network, assigning device  
ID numbers, selecting the mixer mode, and using the front panel LCD menu.  
Hardware Setup  
The diagram below illustrates the typical connections that are made for a single-unit

To connect the unit  
1. Place the unit in a standard 19-inch rack and attach it securely.  
2. If you are using a custom controller for control and status, plug it into the  
DB25 Control/Status A or B port [D].  
If you are using an external RS-232 controller, connect it to the  
RS-232 port [I].  
3. Wire the inputs and outputs to the XAP 800 using the provided three-  
terminal Phoenix push-on connectors.These connectors are designed for easy  
wiring; simply insert the desired wire into the appropriate connector opening  
and tighten down the top screw.  
The three terminals in  
the Phoenix connector  
correspond with the rear-  
panel audio contacts (from left to  
right): + (positive), – (negative),  
and (ground).  
Inputs 1–8 [B] Mic or line level inputs  
Inputs 9–12 [F] Line level inputs only  
Outputs 1–12 [E] Line level outputs  
4. If you are using a ClearOne Remote Panel, wire it to the RS-485 port [C]  
using the provided four-terminal Phoenix push-on connectors.  
5. Plug in the XAP 800 to complete the installation.The power output [A] will  
operate at any level between 100–240VAC and 50–60Hz.  
If you are installing only one XAP 800 and are not connecting it to any other XAP  
or PSR1212 units, you have completed the hardware installation.

Expansion bus connections  
Using the Expansion Bus ports (RJ-45), you can connect up to eight XAP 800/400s  
and 16 XAP TH2 units, where the total number of microphone inputs does not  
exceed 64. Make connections between units in daisy-chain fashion using the short  
RJ-45 jumper. If your units are further apart, use category five twisted-pair cable.  
The maximum distance between interconnected XAP 800/400 or PSR1212  
units is 80 feet (24 meters). Expansion bus cable length is calculated between  
XAP 800s/400s and PSR1212s.The cable connecting a XAP TH2 to the network  
is included in the cable length between the XAP 800 or XAP 400. For example, if  
the cable from the XAP 800 to the XAP TH2 is 50 feet and the cable from the  
XAP TH2 to the second XAP 800 is 50 feet, then the total length between the two  
XAP 800s is 100 feet which is beyond the maximum 80-foot limit.

that the first unit in your E-  
bus network be a XAP 400  
or XAP 800 rather than a XAPTH2.  
2. Connect the RJ-45 jumper cable (or Cat 5 twisted pair cable) to the  
Expansion Bus Out connector of the first unit in the network and  
Expansion Bus In connector of the second unit. Continue connecting units  
in the same fashion.

trol can be provided by  
any unit in the network.  
If the E-bus network is not connected properly, the front panel LEDs will  
flash on the units that are physically connected to the network.To correct  
the problem, check for broken connections and reconnect the expansion bus  
cables.

If the same device ID is  
assigned to more than one  
unit on the E-bus network,  
Device IDs  
Once your expansion bus connections are made (and if you have more than one  
XAP 800 at a site), you need to set up a unique expansion bus device ID number—a  
network address—for each XAP 800 on the network. As shipped from the factory, all  
XAP 800s are set to device ID 0.  
the Meter LED “+12” will flash  
red, the Mic LEDs “1,2,4,”  
and “8” will flash green on the  
affected units. To correct the  
problem, change the device ID on  
one of the conflicting units.  
To assign device IDs  
1. Press the front-panel Enter button, then scroll through the menu until the  
System menu is visible.  
2. Press Enter, then scroll through the menu until Device ID is visible.  
3. Press Enter, then scroll through the eight (0–7) options. When the desired  
device ID is visible, press Enter to select it. (You can also set the device ID in  
the Unit Properties window of G-Ware software see page 25.)  
4. Repeat this process for each XAP 800 on the expansion bus network.  
You can also use G-Ware  
to select a mixer mode.  
See page 25.  
Mixer mode  
There are two mixer mode settings: slave (default) and master. A master unit is not  
required in a networked system and in most installations, all units will be slaves.  
Master units ignore audio from upstream units.This prevents audio from being  
received from units above the master unit in the network. However, global control of  
the system is still maintained by whichever XAP 400/800 or PSR1212 unit is  
connected to a control device through its RS-232 or RS-485 ports. Control is not  
affected by master/slave designations.  
In Figure 2.5, the third unit in the network is a master. It prevents the audio  
from the first and second units from being passed down the network chain.  
Likewise the second master unit in the network will not pass on the audio from the  
unit before it.The third unit provides system-wide control through a connection to  
its RS-232 port.  
To select a mixer mode  
1. Press the front panel Enter button and scroll through the menu until System  
menu is visible. Press Enter to select the menu.  
2. Scroll through the System menu and select Mixer Mode.  
3. Select the mixer setting you want to use.  
Repeat for additional units.

ClearOne  
recommends  
Flow Control (hardware)  
that you leave Flow  
Control enabled.  
The XAP 800 uses the RTS and CTS pins on the RS-232 port to regulate the  
transmission and reception of data.You can enable or disable flow control on the  
front panel of unit and select the flow control type in the Site Properties window of  
G-Ware (see page 23). If you select On (default) from the front panel menu, select  
Hardware as the flow control type in the Site Properties window. If you disable flow  
control on the front panel, select None in the Site Properties window.When None is  
selected, the XAP 800 ignores flow control, making the connected external control  
device ensure that data is not lost. Software flow control (Xon/Xoff) is supported by  
the XAP/PSR units and is only used with a pass-through device, such as a modem.  
To avoid communication errors, ClearOne strongly recommends that you  
connect all DB9 pins and enable flow control when connecting to a PC.  
Enable Modem  
The modem initialization  
string can only be set via  
This parameter configures the RS-232 port for connection of a modem.When On is  
selected, the XAP 800 will send an initialization string to the modem on power-up

Expansion bus O–Z routing  
Audio on any XAP unit in the E-bus network can be placed on the bus or taken off  
the bus and routed to any destination within the unit.The XAP 800 has 12 digital  
mix-minus buses:  
O–R buses are defaulted as the mic mix buses and can communicate the  
NOM count. Gated mics are default routed to the O bus.  
S–Z buses are defaulted as the auxiliary mix buses.They are used to carry  
auxiliary audio such as that from codecs and XAP TH2s.These buses are  
used as mic mix buses when NOM count is not required.  
Process A–H routing  
There are eight processing blocks on the XAP 800 (Processing A–H).With these  
processing channels, you can apply filters, EQ, or other processing settings to an input  
or a group of inputs which can then be routed to a single output or group of outputs.

The Speech Leveler is a compander that is optimized for speech audio. It  
quickly equalizes the difference in speech levels in the room without bringing up noise.  
If you use AGC with the Speech Leveler, set the AGC Response Time to >2 seconds.  
AGC adjusts softer and louder input audio to a consistent level that you select  
(the target level).The target level range is from -30 to 20dB in 1dB steps.The  
default target level is 0dB.  
Set the Target Level first, then apply the amount of maximum gain that you  
want the AGC to apply to the signal. Maximum gain range is 0 to 18dB in 1dB  
steps.The default value is 18dB. AGC occurs after the gain and filter settings in  
the audio signal path.

toolbar button  
Figure 3.30.Virtual Reference window.  
Use this window to select which signals will be used by the four Virtual  
Reference points.The routing matrix portion of this window cannot be edited.Virtual  
references are used when you need to reference multiple outputs. For example, if  
you have stereo outputs (L, R) near a block of mics, you would want the mics’ echo  
canceller to reference both the left and right outputs. By using a virtual reference,  
the echo canceller will be able to reference both signals.This means you don’t need  
to use a dedicated output to combine signals.  
Or, you may have mics routed to the PA output but you don’t want the echo  
canceller to reference this audio. By using a virtual reference, the echo canceller  
can sample all signals routed to the PA output, minus the mic signals.  
To create a virtual reference  
1. Select the input signals you want included in each virtual reference by  
clicking the cross points.  
2. Because AEC requires a physical output reference to track output gain  
changes, you need to select an output reference for AEC to function properly  
with a virtual reference. Use the lists at the bottom of the window to select  
which output you want AEC to use to track gain changes.

Non-linear Processing (NLP)  
The Non-linear Processing (NLP) feature increases the power of echo cancellation  
for difficult acoustical environments. NLP features four settings: Soft (6dB),  
Medium (12dB), Aggressive (18dB), and Off. Use NLP with care; corresponding  
trade-offs can include suppression and half-duplex operation. Default is Soft.  
Meters  
The Echo Return Loss (ERL) meter on the Acoustic Echo Canceller window shows  
the coupling between the reference signal and the input to the echo canceller—the  
ratio of the two levels. It is an average meter that updates only when a signal is  
present.  
The Echo Return Loss Enhancement (ERLE) meter shows the loss through  
the echo cancellation and non-linear processing chain—the ratio of the two levels.  
It is an average meter that updates only when a signal is present.  
The Total Echo Reduction meter shows the total ERL and ERLE reduction, in  
decibels. It is an average meter that updates only when a signal is present.  
NC  
The NC button on the selected input in the Inputs 1–8 window opens the Noise  
Canceller window.The noise canceller reduces ambient noise in the signal with no  
noticeable degradation in signal quality.  
To use noise cancellation, click Enable Noise Canceller, then adjust the  
Cancellation Depth to the setting which provides the best combination of low noise  
and maximum speech clarity.The attenuation depth can be set in 1dB increments  
from 6dB to 15dB. Default is 6dB.

four places (whichever is larger). Bandwidth is from .05 to 5 octaves in .01  
octave increments. Level is fixed at -80dB.  
PEQ (parametric equalizer). Center frequency range is 20Hz to 20kHz  
with resolution to 1Hz or 4 places (whichever is larger). Bandwidth is .05 to  
5 octaves in .01 octave increments. Level range is -15 to +15dB in 0.5dB  
increments.  
Frequency. Use Frequency to select the center frequency (in Hertz) for the filter you  
are configuring. Range is from 20Hz to 20kHz. Default is 1kHz.  
Gain. Gain adjusts the gain value from -18 to 18dB, in .5dB steps. Default is 0dB.  
Q, or Quality factor. Q, or Quality factor, selects the ratio of the center frequency  
divided by the bandwidth. Q reflects an inverse relationship to the bandwidth, and  
adjusts from .02:1 to 40:1 on the XAP 800.

Gate  
The XAP 800 has unique gating parameters which control microphone activation.  
The Gate button on the selected input in Inputs 1–8 window opens the Gate  
configuration window where you can establish the gating parameters for the input.  
Activation  
There are three mic activation settings: Auto Gate, Manual On, and Manual Off.  
Auto Gate determines mic gating based on the input level and gating settings  
for the gating group the input is assigned to. It contributes to and is affected  
by all gating group settings such as NOM, chairman override, etc.  
Manual On activates a mic, provided it does not exceed max NOM  
requirements of the gating group that the input is assigned to. It is included in  
the NOM count.  
Figure 3.34. Gate window  
Manual Off deactivates a mic.  
Chairman Override  
Chairman Override provides gating priority for this mic input over any other mic input  
within the same gating control (mixer) groups.When a mic with Chairman Override  
enabled gates on, all mics which don’t have Chairman Override enabled will gate off.  
Default is off.  
Adaptive Ambient  
Adaptive Ambient adjusts the ambient reference level as noise and room conditions  
change.When adaptive ambient is on, the mic channel monitors the ambient noise  
level on the input and adjusts the ambient level reference automatically.This means  
that the gate threshold level automatically increases or decreases based on back-  
ground noise. If Adaptive Ambient is turned off, the input will use the fixed ambient  
level specified in the Ambient Level box as its gating reference. Default is on.  
PA Adaptive Mode  
PA Adaptive Mode uses loudspeaker audio level on a specified output as the new  
ambient level when audio is present at the power amplifier.This prevents loudspeaker  
audio from gating on the mic, while still allowing people in the room to gate on  
microphones as they speak—provided that their voices are louder than the  
loudspeaker audio. For example, you might decide to play background music from a  
CD player during a presentation. PA Adapt Mode allows you to use the output routed  
from the CD player as the ambient reference to prevent the CD player’s audio from  
gating on microphones. An output must be specified as the PA Adaptive Reference  
(this is the same as the AEC reference) for each mic in the system. Default is on.

level before the channel gates on.The gate ratio range is from 0 to 50dB. Default is  
15dB.  
Hold Time  
Hold Time determines how long the channel stays gated on after the audio is below  
the threshold.The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.  
Off Attenuation  
Off Attenuation sets the amount of level reduction applied to a channel when it is  
gated off.The range is from 0 to 50dB. Default is 12dB.  
Ambient Level  
Ambient Level is available only if the Adaptive Ambient feature isn’t enabled. Use  
Ambient Level if you want to specify a fixed reference point rather than one that  
adjusts for background noise.The range is from -80 to 0dB. Default is Off.  
Decay Rate  
Decay Rate determines how fast a channel gates off after the hold time expires.  
Default is Medium.

PA Adapt and AEC Reference  
The PA Adapt Reference  
and AEC Reference are  
the same for each channel.  
When using either the PA Adaptive mode (see page 38) or Acoustic Echo  
Cancellation (see page 33), the output that carries this information, i.e. the reference  
output, must be defined. Select the PA Adapt and AEC Reference from the drop-  
down list. Any one of the 12 outputs, four expansion bus references, or four virtual  
references can be selected.  
If you change the PA Adapt  
Reference for a channel, you will  
also make the same change to that  
channel’s AEC Reference.  
If you select an expansion bus reference, the Define PA Adapt/AEC  
Expansion Bus Ref window opens so you can identify which expansion bus output you  
want to use as the PA reference.You can also open this window from the toolbar.

If you select a virtual echo cancellation reference point, the Virtual  
Reference window will open.This window allows you to select which signals will be  
used by the four virtual reference points. Virtual references are used when you need  
to reference multiple outputs.The routing matrix portion of this window can not be  
edited.You can also open this window from the G-Ware toolbar.

Gating Group Select  
In addition to specifying gating characteristics for each mic input, you can assign the  
inputs to a gating group for greater flexibility and control.When inputs are assigned  
to a gating group, the gating information from the inputs is used to control how the  
entire mixer behaves.  
Figure 3.39. Gating  
Group Select pane  
The XAP 800 features four internal gating groups (Internal 1–4) and four  
global gating groups across the expansion bus (Global A–D). Microphones can only  
be used in one gating group at a time. If an input is not assigned to a gating group,  
that mic’s gate properties are independent and have no effect on any other gating  
group. When gating groups span two or more units (global gating groups), the  
settings must be the same for each unit attached to the global gating group. Mic  
inputs are routed to Global Group A by default.  
To assign a gating group  
Select the Internal or Global group the mic input will belong to or select  
None.  
To configure gating group settings  
1. Click the Gating Control button on the toolbar.This opens the Gating  
Controls window.  
Figure 3.40. Gating Control button  
Figure 3.41. Gating Controls window  
2. Select the Max # of Mics (default is 4).  
This sets the maximum number of microphones that can be gated on at any  
one time within a gating group. For internal groups, the maximum number of  
mics can be from 1 to 8. For global groups the maximum number of mics  
will vary depending on how many mic inputs are assigned to the gating group  
(up to 64).You can also select All for the global groups—which means all  
mics could gate on.

3. Leave 1st Mic Priority selected (default) to enable this feature; otherwise,  
clear the selection to disable it. ClearOne recommends leaving this setting on.  
This setting helps maintain maximum audio intelligibility by allowing only  
one mic to gate on to a participant’s voice. 1st Mic Priority allows more  
than one microphone to be activated at the same time—it simply restricts  
mics from gating on to the same audio source. It does this by determining  
the audio level received by all mics when the first mic is gated on.This audio  
level is then used as the ambient level for the gating group. If this feature is  
disabled, usually two or more microphones gate on when only one person  
speaks.  
4. Select last-mic operation from the Last Mic Mode list.There are two  
options for Internal groups: Last On and Off. If you are configuring Global  
groups, you can select from the mic inputs assigned to the Global group in  
addition to Last On and Off.  
Last On leaves the mic that was activated last full on until another mic input  
is gated on.The Input setting allows you to select which mic input the  
XAP 800 leaves on when all mics gate off. If Off is selected, all mics will  
gate off when no audio is present. It is preferable in most applications to  
leave a mic on so the remote participants don’t think they have lost their  
audio connection. Off is typically only used when you are conferencing  
multiple sites and need to reduce background noise.  
5. Click the Gating Group label to change the group names.  
Gain  
The Coarse and Fine sliders on the selected input on the Inputs 1–8 window are used  
to match the level settings for microphone inputs and to adjust input volume level.  
Set the Coarse gain to 55dB for a mic input, 25dB for active equipment that  
requires an input between mic and line level, or 0dB for a line level input.  
Use the Fine gain slider to adjust input volume level. You can also enter the  
level directly in the 0.0dB box.

Optimizing input gain structure  
How you adjust an input’s gain directly affects sound quality.The optimal input gain  
setting is one which is adjusted as high as possible above the noise floor without  
introducing clipping. Clipping can cause distortion which can damage amplifiers and  
loudspeakers.  
To adjust the input level properly, place a signal on the input at the maximum  
level it will generate. Adjust the input gain until the peak level of the input, as  
shown on the Input meter, just begins to enter the red (clipping) zone, then reduce  
the gain slightly until peaks no longer climb into the red zone.This setting will  
ensure that the XAP 800 maximizes the signal-to-noise ratio without clipping the  
signal.  
Meters

CHAPTER 4: Advanced  
Configuration  
Presets  
Overview  
For many audio conferencing applications, a great deal of system flexibility is needed  
to meet the challenges presented by changing meeting or conference room  
requirements.These requirements may include changes in muting, audio sources,  
room orientation, or room combining. And ideally, these changes are made  
instantaneously—without interrupting or affecting any meetings in progress.  
Using presets enables you to accommodate these changing room requirements  
quickly and efficiently. When you create a preset, you are essentially creating a  
single room configuration option. Presets can be programmed with a variety of  
routing, level, gating, delay, filter, and EC reference settings to meet specific  
application requirements.You can change every unit parameter or a select few  
depending on your room needs. XAP 800 presets are unique in the sense that they  
operate independently of other presets in the unit. When a preset is run, only the  
selected inputs/outputs are changed—all other settings in other presets remain  
unchanged and are not reset.This means you can change audio routing and  
configuration settings in a room without affecting settings in other rooms (such as  
gain).You can create up to 32 presets for the XAP 800.  
Presets are used only  
within the local  
XAP 800 unit. However, if  
a preset is part of a macro, it can be  
activated on a networked XAP 800  
unit.  
Presets can be executed in a variety of different ways including the Execute  
Preset utility in G-Ware, the front panel controls of the XAP 800, RS-232 external  
control devices, RS-485 control devices (ClearOne Control Panel and XAP IR  
Remote), logic in/out, and contact closure.You can also create macros which can  
run multiple presets.These options give you tremendous flexibility when designing  
your installations and will be described in more detail in this chapter.  
Creating Presets  
Presets are created in G-Ware using the Preset mode.To switch to Preset Mode,  
click the Preset Mode button on the toolbar or the Preset Mode button on the Flow  
Screen.The Preset Mode window (see Figure 4.2) consists of the Preset  
Configuration Pane (left side of the window), the G-Ware menus and toolbar  
(although most options are not available because they do not apply to presets), and  
the Preset Matrix Screen.There is no Flow Screen in Preset Mode since all  
configurable settings can be accessed from the Matrix Screen.

Control/Status B  
A typical use for Preset Mask Control Status B is a room combining  
application which uses automatic partitions with sensors or triggers which set the  
pin to high (H) when the partition is closed and to low (L) when the partition is  
open. For example, if pin 1 is connected to the first partition and Pin 3 is  
connected to the second partition, then the Preset Mask Control Status B settings  
shown in Figure 4.4 will activate the preset when the first partition is open and the  
second partition is closed.

space, G-Ware will alert you when you try to save the preset.You will be asked to  
reduce the number of cross point changes or the number of macros in the preset. As  
a general rule, if you make cross point changes to three-fourths of the matrix, you  
can establish a maximum of 128 nested macros for a given preset.

Running presets  
Presets can be run from G-Ware or the front panel controls on the XAP 800.You  
can also program external control devices (such as AMX or Crestron, ClearOne  
Control Panels, XAP IR Remote, and GPIO devices) or use macros to run presets.  
See Chapter 6: Control for more information on creating custom control.  
To run a preset using G-Ware  
1. Select the Execute Preset button on the G-Ware toolbar.  
2. Select the preset you want to execute from the Preset list.

Running multiple presets simultaneously  
To run multiple presets at the same time, you need to create macros (see page 63). A  
macro is a series of commands which can be executed from G-Ware or by using any  
external control device.Typically you will create a macro for each configuration or  
group of presets you want to run at the same time.This ability to run multiple presets  
is critical in applications such as room combining. However, not only do you need to  
be able to run multiple presets simultaneously, you also need to be able to change  
presets without affecting other presets.  
It is also possible to assign  
states to presets when  
creating Remote Panel,  
In order for this to happen, the system needs to know which presets have been  
run and shouldn’t be rerun and which ones are ready to run.You supply the system  
with this information by setting the state (or flag) of the preset when creating the  
command line in the macro.The three options are:  
serial, or GPIO control. However,  
unless you create macros, you will  
only be able to run one preset at a  
time.  
0 = to set the state to off  
1 = to execute the preset and set the state to on  
2 = to execute the preset and set the state to off

Advanced Configuration ~ Presets  
61  
Figure 4.9. Assigning a state to a preset command in the Macro Editor  
If a preset is flagged as “On,” nothing will happen when the preset is executed  
again because the system knows it has already been run.This prevents any manual  
adjustments that are made during the course of the meeting (gain, muting, etc.)  
from being lost.  
Room combining example  
In the room combining scenario depicted in Figure 4.10, there are four possible room  
configurations using six presets (P1–P6). In order to change configurations without  
disturbing meetings in progress, a macro must be created for each configuration that  
tells the system what to do with each of the six presets.  
You can also create a  
macro to set all preset  
flags to 0 which ensures  
all presets are ready to run again.

When the room is in Configuration 1, running the Configuration 2 macro will change  
the presets to the following states:  
P1 does not change because the flag is already set (1)  
P2 and P3 clear their states (0) so they can be run  
P4 runs and sets its state to on (1) which prevents other presets from  
reruning it  
P5 and P6 clear their states (0) so they can be run  
When the room is in Configuration 3, running the Configuration 1 macro will change  
the presets to the following states:  
P1 and P2 run and set their state to on (1) which prevents other presets  
from reruning them  
P3 does not change because the flag is already set (1)  
P4, P5, and P6 clear their states (0) so they can be run

Macros  
A macro is a series of commands which can be run from G-Ware, the front panel  
controls, or by using any external control device. Macros streamline the operation of  
the XAP 800, allowing you to make quick configuration changes and, as previously  
discussed, making it possible to execute multiple presets simultaneously (see pages  
60–62). Macros can also contain commands that are executed on other XAP units.  
See pages 97–98 for a list of commands which can be used in macros.  
The XAP 800 is designed to support up to 255 macros, with an average of  
150 command lines each. In the unlikely event that you exceed G-Ware’s capacity,  
you will be notified with a warning that indicates the command line at which  
memory is exceeded.  
Creating macros  
There are two ways to create macros in G-Ware: the Macro Recorder, which  
records your onscreen selections, and the Macro Editor, which allows you to  
directly create command lines.The Macro Editor is also used to edit macros  
created using the Macro Recorder.  
To create a macro using Macro Recorder  
1. Click the Macro Recorder button on the G-Ware toolbar.The Macro Record  
Figure 4.11. Macro  
window opens and the mode is changed to Macro on the status bar.  
Recorder toolbar button  
When you select an  
existing macro as the  
macro to record, the new  
recording is appended to the end of  
the existing macro.  
Figure 4.13. Macro Record stop window  
Figure 4.12. Macro Record start window  
2. Select the macro number from the Macro to Record list, then click Start.  
3. Make any routing and input/output configuration changes (such as gain  
adjustments, mute, etc.) to be included in the macro. Make these changes the  
same way you made changes in Configuration mode (see Chapter 3: System  
Configuration for more information).  
4. Click Stop in the Macro Record window in the upper right-hand corner of  
the screen.This stops the macro recording and opens the Macro Editor  
window. See page 65 for editing instructions.

CHAPTER 6: Control  
There are many ways to control your XAP 800 and other networked units.This  
chapter explains how to set up control for Control/Status A port using GPIO Builder,  
XAP IR Remote and ClearOne Control Panel using Remote Builder and RS-232 port.  
GPIO Builder  
Control/Status A  
GPIO stands for general-purpose input/output.The GPIO Builder is used to establish  
the pin assignments for the 16 user definable pins on Control/Status Port A.These  
pins provide control via contact closure and status via open collector functions in the  
unit. Note that the pins numbered in blue are command pins; the pins numbered in  
green are status pins.The default pin assignments are listed on page 88.You can  
open GPIO Builder from the Flow Screen or the G-Ware toolbar.  
To program control/status pins  
If you want to create pin  
assignments specific to a  
preset, you will need to  
open the GPIO Builder from the  
Preset Configuration pane (see  
page 57) and select Use in Preset.  
1. Select the Control/Status A pin you want to configure.  
The current (default) pin assignment is displayed in the Active  
(Low)/Inactive (High) Command box.  
GPIO commands can be  
configured only for the  
local XAP 800 unit.

RS-232 Port  
Remote Modem Access  
You can access the unit remotely through a modem connected to the serial port.To  
enable this feature, configure the port for modem mode.  
When in modem mode, the serial port will send an initialization string to the  
modem upon entering the mode or upon power-up of the unit.You program the  
initialization string in Site Properties window in G-Ware.Typical configurations you  
set with the initialization string include setting a fixed baud rate for the unit and  
setting up auto-answer parameters.  
The modem password is  
created in the Unit  
Properties window (see  
You must enter a password before you can control the system this way.The  
default password is blank (a carriage return).You can change it to any  
combination of letters and/or numbers up to 12 characters. It is not case-sensitive.  
page 26) or by using the MPASS  
serial command (see page 117).  
When you establish a valid serial connection with the unit in modem mode, the  
unit will wait for a carriage return. When you have entered a carriage return, the  
system will prompt you to enter the password. If there is no activity for five  
minutes on the serial port while in modem mode, the unit will re-prompt for the  
password.  
Serial commands  
Serial commands can be passed through the XAP 800 RS-232 port using Hyper  
Terminal, touch panels, or other compatible remote control devices.To learn more  
about serial commands, see Appendix E.

Control/Status connectors  
The Control/Status connections are provided on two DB-25 connectors.These  
connectors are labeled Control/Status A and Control/Status B and contain different  
types of pins.The inputs on these connectors are internally pulled high and are  
activated by connecting the pin to ground.The outputs are open collectors, which are  
open when inactive and grounded when active.This allows the XAP 800 to control  
and be controlled by a wide variety of external devices, including relays, lamps,  
switches, and other equipment. Control pins on Control/Status A are momentary  
while control pins on Control/Status B are latching.

applicable local electrical  
The Volume Control Panel and Select Control Panel connect to either the Remote  
Panel A or B connector of the PSR1212, XAP 800, or XAP 400 and works by  
triggering the execution of programmed commands from the XAP/PSR unit. Each  
button on the control panel is programmable to execute a single command or a  
series of commands. Button function is programmed using G-Ware software (see the  
XAP or PSR user manual). Each Control Panel fits inside a standard electrical wall  
box and must be installed according to local electrical codes.

2. Using DIP switches 1–4, assign a unique ID to the Control Panel. Refer to  
Figure C.2 for proper DIP switch settings. If you set an invalid address, all LEDs  
on the Control Panel will illuminate.  
3. Set DIP switch 8 to the on position if you are using just one Control Panel. If you  
have more than one Control Panel daisy-chained to the same Remote Panel  
connector, set only the last Control Panel’s DIP switch 8 to on. Switches 5-7 are  
nonfunctional.  
4. Turn off the XAP/PSR unit (unplug the unit).

Appendix E: Serial Commands  
The XAP 800 accepts serial commands through the serial port or the expansion bus.The commands in this manual  
pertain only to the XAP 800. RS-232 serial port protocol is 9,600, 19,200, 38,400 (default), or 57,600 baud; 8  
bits, 1 stop bit, no parity.  
Conventions  
The following typographic conventions are used in this document to describe the different serial commands. Use the  
Command structure section and the examples as a guide when creating your serial commands.  
Convention  
Description  
<X>  
Parameters enclosed in < > indicate a mandatory parameter.  
[X]  
Parameters enclosed in [ ] indicate an optional parameter.  
1-8  
Parameters separated by a - indicate a range between the values.  
Parameters separated by a , indicate a list of available values.  
4,7,9  
EREF  
DEVICE  
Words in uppercase bold indicate command text.  
Indicates the device type and device number on the expansion bus network. It is composed of a  
device type character and a device number.The device type for the XAP 800 is always 5 and the  
device ID will always be 0–7, or * (to select all 800 units).  
Command structure  
Commands can be either UPPER CASE or lower case. Also, extra spaces or tabs between arguments in text commands  
are allowed. Return values are always in upper case. In order for a command to be recognized by the serial port, the  
command must be terminated by a carriage return.  
The structure of serial commands is as follows: #DEVICE COMMAND [X] [X]  
#
indicates the start of a command line  
DEVICE  
COMMAND  
[X] [X]  
represents the device type and device number  
is the command text  
represents any additional options in the order that they appear in the command descriptions that  
follow  
Example  
A command to disable automatic gain control for Mic 2 on a XAP 800 device “0” will have the command line:  
#50 AGC 2 M 0. In this command line, 5=XAP 800, 0=unit 0, AGC=command, 2=channel, M=Mic Input group, 0=off  
state. If a command calls for a “null” value, leave a blank in the command line. For example,#50 AGC 2 M” will  
return the current AGC state of Mic 2 on device 50.  
Command responses will have a carriage return line feed. Example: #50 AGC 2 M O carriage return line feed.

Groups and channels  
If a channel has an alpha value of “*”, the command is to be applied to all channels. For example, a group value  
of M and a channel value of * would mean that the command is to be applied to all channels of group M (mic  
inputs).The following table shows the alpha representations for the different groups and the channels that are  
available for each product.

Acoustic Echo Cancellation (AEC) A process in which acoustical echo is  
removed from a signal. AEC can be used to remove unwanted signals from mic audio  
if the unwanted acoustic signal is available separately as an electronic signal.  
Adaptive Ambient This portion of the mixer monitors the varying ambient noise  
level in the room and changes the threshold level at which a microphone gates on.  
Ambient Level The manually-set background noise level upon which the XAP 800  
bases gating protocols. Used only if the Adaptive Ambient feature isn’t used.  
Ambient Noise The existing room-level noise, such as that caused by ventilation  
systems, paper shuffling, and background chatter.  
Amplitude Plot A plot of amplitude (-18 to 18dB) vs. frequency (20Hz to 20kHz)  
on a logarithmic scale.  
Attack Time This signal parameter determines how quickly compression is enabled.  
It is calibrated in milliseconds.  
Attenuation A reduction of signal amplitude.  
Audio Processor A device that modifies an audio signal in response to certain  
requirements.  
Audio routing The process of routing input signals (Mics 1–8, Inputs 9-12, From  
E-bus, From Processing) to output destinations (Output 1–12,To E-bus,To  
Processing) in the Matrix screen.  
Automatic Gain Control (AGC) Automatically increases or decreases audio gain  
to maintain a consistent audio level.  
Automatic Gating Automatically gates microphones on or off based on input levels  
and other parameters programmed into the XAP 800.

band. Also, the range or differences between the limiting frequencies of a continuous  
frequency band.  
Baud Rate The number of signal transitions per second, or the clock rate of the  
serial bit stream in hertz. Given 7 or 8 bits for data plus start and stop, the  
approximate ASCII character transmission rate is one-tenth the baud rate.

Chairman Override Provides gating priority for chairman override enabled  
microphones within the same gating group.When a mic with chairman override gates  
on, all mics which don’t have chairman override enabled and are in the same gating  
group will gate off.  
Clipping A condition in which a signal level exceeds the maximum level a circuit can  
handle.This is usually caused by improper gating parameters and gain settings. It  
causes distortion and typically leads to listener fatigue and accelerated failure of  
loudspeaker drivers.  
Compression An induced reduction in the dynamic range of part or all of an audio  
signal. Compression is usually used to protect individual loudspeaker components  
from the damaging effects of transients.  
Compressor The compressor is part of the processing settings and allows you to  
change the gain transfer characteristics of the signal path and to control the  
dynamics of the signal.

to the units. Control is not affected by master/slave settings and will continue to  
function even if the units are not using the audio channels.  
Constant Directivity Horn Equalizer (CD Horn EQ) Horn drivers commonly  
used in arrays in arenas and auditoriums have an inherent 6dB/octave high frequency  
rolloff.The XAP 800’s CD Horn EQ compensates for this characteristic.  
Crossover A device that passes designated frequency segments of an audio signal to  
various loudspeaker elements in a sound system.  
Bessel A crossover using a low-pass filter design characterized by a linear  
phase response.This results in a constant time delay throughout the passband.  
Butterworth A crossover using a low-pass filter design characterized by a  
maximally flat magnitude response.This results in no amplitude ripple in the  
passband.  
Linkwitz-Riley A fourth-order crossover consisting of a cascaded second-  
order Butterworth low-pass filter. Offers a vast improvement over the  
Butterworth crossover and is the de facto standard for professional audio  
active crossovers.
