DN9340E & DN9344E Key Features
2. INTRODUCING THE DN9340E/DN9344E
The Klark Teknik DN9340E Helix digital equaliser is a two-channel audio digital equaliser packaged in
a 2RU, 19” rack-mounting format. The two channels can be controlled independently as two separate
mono equalisers or linked for stereo operation. The unit has been designed to build on Klark Teknik's
unrivalled reputation for high quality equalisation, while addressing a number of limitations in more
conventional products.
The Klark Teknik DN9344E Helix Slave digital equaliser is a 1U slave version of the DN9340E unit. By
packaging FOUR channels of Helix processing into a 1U case, it offers unrivalled space efficiency, with
a cost per channel lower than many less flexible products. The DN9344E can be controlled from a
master DN9340E unit or by an external computer, and also has provision for contact closure
operation.
2.1. Host Software Versions
This Operator Manual applies to Klark Teknik DN9340E and DN9344E Helix units that are running host
software versions 4.01 and later. To check whether this manual covers the host software version that
your unit is running, visit our website shown at the front of the manual.
2.2. Key Features
Key features of each unit are:
ꢀ
Simultaneous availability of graphic and parametric equalisation
In addition to the obvious advantages of a dual-purpose unit, this allows the engineer to separate out
different sections of equalisation. For example, during setup and any sound check, the parametric
mode can be used to set a basic EQ for the venue, with maximum flexibility. Once the show starts,
however, the engineer can flip to graphic mode, which now starts off from a ‘flat’ baseline. Any
problems that need fast attention during the show can now be addressed using the speed of
operation of graphic EQ, and without confusion between the ‘showtime’ EQ and the original venue
setup. At any time, a quick look at the home page will show the true overall response of the unit.
ꢀ
Threshold Dependent Dynamic EQ (
)
Over the years a number of dynamic EQ products have been introduced. These typically resemble a
combination of a dynamics processor and an equaliser. This approach has the disadvantage that,
while it is usually fairly easy to determine the level at which the dynamic EQ will start to operate, it is
much harder to visualise the likely effect as the system is pushed harder or to set a maximum
amount of EQ. The unique
system developed by Klark Teknik with its dual thresholds
provides unrivalled clarity of operation making this a very practical tool.
ꢀ
Speed of operation
Since the advent of digital signal processors, it has been possible to pack ever more functions into
smaller boxes. However, if a function is buried in a hard-to-find sub-menu, which is only accessible
after navigating a complex series of button presses, it may as well not be included. In live
production, the operation of the unit is as crucial as the sound quality and this is a key part of the
Helix design. The 2RU format permits a large graphic LCD display, while a second alphanumeric
display provides clear value readouts above the control knobs without using up space on the main
LCD. Dedicated selection buttons for the main functions, clear LED indicators, and no less than eight
separate bargraph meters ensure that the unit is fast and accurate in operation. The unique
two-section touchstrip provides instant access to filters and faders, so that Helix provides the same
feeling of being “in control”, which is familiar to users of Klark Teknik analogue graphic equalisers.

DN9340E & DN9344E Key Features
ꢀ
Space efficiency
The Helix system allows exceptionally compact EQ systems to be assembled. For example, one
DN9340E and six DN9344E units would provide 26 channels of EQ, each with graphic, parametric,
and dynamic EQ, plus flexible filters, all in 8U of rack space.
ꢀ
Interface to Midas consoles
To further enhance the speed of operation of the Helix system, an interface is provided that connects
to Midas Heritage and Legend series consoles. This allows the EQ system to be controlled
automatically from the solo system of the console, ensuring that the correct EQ device is always
ready for instant access.
ꢀ
Remote control operation
A slave network comprising DN9340E/DN9344E units linked together can be remotely controlled from
a PC running the associated Elgar software application via the real panel Ethernet comms connectors
(or RS-232 PC port on the front panel). This network can provide up to 32 channels, each with A and
B inputs.
Alternatively, a DN9340E master unit can control a network comprising up to 32 channels provided by
DN9340E and/or DN9344E units acting as slaves. The master unit also acts as a single slave.
ꢀ
Store and Recall Parameters
The DN9340E includes two types of memory location, to provide maximum flexibility in a range of
applications. There are 32 user memories in battery-backed-up SRAM and 32 preset memories in
non-volatile FLASH memory. Recalling settings from either memory type uses the same procedure,
and the user memories can be stored directly from the front panel of the unit. However, the FLASH
memories can only be programmed directly from an external computer. This provides an absolute
safeguard for valuable system settings, particularly in fixed installations.
Klark Teknik has a policy of continuous development and may produce updates to the DN9340E or
DN9344E host code. These can be downloaded to the unit via the front panel PC Port. To keep up

Access buttons to control each type of equalisation: GRAPHIC,
PARAMETRIC, DYNAMIC, and FILTERS. Pressing one of these
buttons selects the type of EQ to be controlled. These
buttons do not affect the actual sound at all - they just
activate the controls. The large display will change to show
the display for the selected EQ type, and the TYPE bypass
LED will indicate whether this section is bypassed or not.
The buttons illuminate to show which type of EQ is currently
being controlled. Press the HOME (SETUP) button to return to
the home page, which will show the overall system
response.

EQ active LEDs
These show if a particular type of EQ is currently affecting
the overall response. Note that this is not just an indication
of the bypass state. For example, if all the faders on the
graphic EQ are flat, then the LED will not illuminate. If the
graphic is not bypassed, and then a fader is moved away
from zero, the LED will now illuminate to indicate that the
response is now being affected by the graphic. This is
particularly useful on the home page where it can be quickly
seen what is contributing to the overall response.

options for that type of EQ. Additional functions include
adding new filters (parametric and filter modes only) and
selecting an individual fader or filter to be in or out. On the
home page these buttons access the gain, delay, naming
and A/B Link functions.

Two part touch strip
The touchstrip is used to select individual faders or filters
and can also be used to adjust gain settings. Press either
part briefly to select a particular filter or fader. Press and
hold or tap repeatedly to increase the level (upper strip) or
reduce it (lower strip). Note that the lower strip is deeper
than the upper one to reflect that it is generally more urgent
to reduce gain. Pressing the upper and lower strips
simultaneously allows the creation of fader groups.

6.1. Home Page
The home page is accessed from any of the EQ pages by pressing the HOME (SETUP) button. In the
setup menu the HOME (SETUP) button is pressed repeatedly to move through the menus. After the last
menu entry the display returns to the home page.
On the home page, the large display shows the overall system response. Along the top edge, on the
right, is the Memory number for the currently selected User or Preset Memory settings (storing and
recalling settings are described later).
The alphanumeric display shows the unit name and the name of the current working memory. On the
home page, the bypass button will bypass all processing for the selected channel (A, B or both if
linked for stereo in the setup menu).
6.1.1
Home page sub-menus
This menu provides controls for the overall delay of the system and the input gain trim.
The delay may be adjusted in coarse increments of 2.08ms (one sample at 48kHz sample rate) using
the left encoder or in fine increments of 0.02 ms with the centre encoder. It is displayed in time units
by default. Alternatively, the display can be selected to show distance in either Metric or Imperial
units. Details of changing the units are found in the Setup menu section on page 32.
The input gain control is adjusted by the right hand encoder between -40dB to +12dB in 0.1dB steps.
Below -40dB the gain is set to “Off” and this mutes the input signal.
Press HOME (SETUP) to return to home page.
6.1.2
A/B Link
This menu allows the unit to be linked for stereo operation.
Turn the right-hand encoder to select linked or non-linked (mono) mode. Note that when linking, the
currently displayed channel will be copied to the other channel, so that both channels are then
identical. In other words, if the “A” lamp (adjacent to SELECT button) is illuminated the settings for
Channel A will be copied to Channel B. If the “B” lamp is illuminated, the settings for Channel B will
be copied to Channel A.

Select graphic equalisation by pressing the GRAPHIC button.
The default display for the graphic EQ is 31 faders indicating the gain of the 31 bands of the 1/3
octave equaliser. The left encoder can be used to select a fader and then the right encoder can be
used to set the gain for that fader. Alternatively, the fader can be selected using the upper or lower
section of the touch strip. If the touch strip is pressed for longer than half a second then the selected
fader will move up (upper strip) or down (lower strip) until the touchstrip is released.

ꢀ Automatic features page
•
Auto Gain - this feature, originally introduced on the Klark Teknik DN3600 equaliser,
automatically adjusts the system gain so that the overall program level remains constant
despite changes in equalisation. The left encoder enables or disables this feature. If set to
“No” then the graphic EQ gain trim (operated by the centre encoder) is entirely manual in
operation. If set to “Yes”, then as the graphic EQ faders are moved, the gain trim will
automatically be adjusted to compensate for the overall (average) level change. At any
time, the display over the centre encoder will show the actual gain trim being applied, and
this can always be adjusted manually (even when Auto EQ is active).
•
Auto-EQ - Available only if the optional DN6000 interface is fitted, and a Klark Teknik
DN6000 Real Time Analyser is connected to the DN9340E master. Use the 16-way ribbon
cable (supplied) to interconnect the units, linking the DN9340E Expansion Slot 2 to the
DN6000 Data Output connector.
This function enables automatic room equalisation based on an audio spectrum from a DN6000.
Note that the DN9340E auto equalises on the basis of a captured DN6000 ‘snapshot’; it does
not auto-equalise in real-time. The Helix unit generates a reciprocal response curve that
compensates for peaks and troughs in the snapshot audio spectrum, so creating a overall flat
response.
Auto Eq defaults to ‘No’. To select Auto Eq, turn the right encoder clockwise. An AutoEq soft
key is added below ‘Menu’ and you are prompted to set the graphic EQ response to a 1/3
octave symmetrical response (Q = 7.8), unless this is already set, as this is the only response
that matches the filtering in the DN6000. Turn the centre encoder clockwise to confirm, or the
left encoder clockwise to cancel Auto EQ. To capture the ‘snapshot’ audio spectrum, press the
AutoEq soft key.
In remote control applications, any slave unit can have the audio spectrum snapshots captured
by the master unit. A slave DN9340E cannot capture snapshots from a DN6000 connected
directly to it.
ꢀ EQ - Flat page
This page allows the graphic EQ faders to be quickly reset to their unity gain position. To
flatten the response, turn the centre encoder clockwise, then turn the right encoder clockwise
to confirm. Pressing any other button will abort the sequence.

6.2.2
Touchstrip operation with Graphic equalisation
On the Graphic EQ page, the touchstrip provides an alternative to using the encoder knobs for
selecting and operating the faders on the display. If you are not currently using the Freq/Level
menu, the unit automatically switches to it when you press the touchstrip. Touch either the upper or
lower part of the touchstrip below the fader frequency that you want to select. The fader will
highlight to indicate the selection. Tapping repeatedly at the same position will result in the fader
level moving up (upper strip) or down (lower strip) in 0.5dB increments. Pressing the strip
continuously in the same place will result in the fader ramping up or down over its full range. As an
aid to resetting faders to exactly 0dB, this ramping motion will stop as the fader passes over the 0dB
position. Release the touchstrip and then press again to continue moving past this point.
6.2.3
Grouping
Groups of faders can be created and moved together. This is achieved by pressing below one fader
on the upper strip, and below a different fader on the lower strip. A group will be created that
includes all faders between those two selected ones. This can now be moved up and down using the
encoder knob or by using the touchstrip in the area below the group. Pressing the touchstrip outside
the range of the group or moving the “frequency” encoder knob will disband the group.

6.6. Metering
Comprehensive audio metering is provided by eight LED bargraph meters:
There are a pair of input meters (labelled “A” and “B” for audio channels A and B,
respectively) that show the input level immediately following the input gain
control. These can therefore be used as a guide for setting the input gain to
match the signal level being sent to the unit. With the input gain control set to
0dB (unity gain) then full-scale on the meter will occur at a signal level of +21dBu,
which is the maximum permissible signal level. The input meters incorporate a
red ‘clip’ LED that indicates signal clipping both on the actual input to the unit and
also after the gain control. This ensures that all possible clip conditions are
monitored irrespective of the setting of the gain control.
There are a pair of output meters (labelled “A” and “B” for audio channels A and
B, respectively) that show the output level from the unit. Full-scale on the meter
indicates maximum output from the unit, which corresponds to +21dBu. The
output meters also incorporate a red ‘clip’ LED. This indicates signal clipping
within the unit, and is monitored at all internal points where gain can be applied.
Thus, if a large amount of gain is added with one section of a parametric EQ,
resulting in a clipped signal, but the level is then reduced by a subsequent EQ
section, the clip LED will still illuminate to indicate the internal clip condition
despite the apparently safe output level. In this situation the input gain should be
reduced to provide sufficient headroom for the desired EQ characteristic. Note
that because these meters are on the output of the unit, they will show the effect
of any delay that has been selected.
There are four meters which show the action of the
dual-threshold
dynamic EQ system, one meter for each EQ section on each of the two audio
channels A and B. The dynamic EQ meters are calibrated in percentage terms,
from 0 to 100. If no dynamic EQ is selected or if the signal is below the ‘low’
threshold, then the meters will show 0% (that is, no LEDs illuminated). Under this
condition the dynamic EQ will be using the ‘low’ frequency response settings. If
the signal level is above the ‘high’ threshold, the relevant meter will indicate 100%
(fully illuminated) showing that the ‘high’ EQ settings are now being applied. If
the signal is between the two thresholds, then the EQ will be morphing between
the two EQ settings, and the meter indicates the signal level relative to the two
thresholds. Note that the effect of the attack and release controls is also indicated
on these meters - the height of the bar indicates the actual EQ being applied, so if
a slow release is set, for example, you will see the meter drop back slowly
following a peak.

6.7. Clear Down Sequence
Because of the comprehensive facilities available on the DN9340E, it may be important to ensure that
the unit is ‘cleared down’ before use. Remember to clear down both channels A and B if the unit is
not linked for stereo operation. There are a number of possible strategies for this:
ꢀ A. Recall a memory that contains a suitable set of default values
See Section 8 for further details on storing and recalling memories.
ꢀ B. Select each type of EQ, and bypass them in turn as follows:
1
2
3
Press GRAPHIC, then BYPASS (the TYPE bypass LED illuminates), PARAMETRIC, then BYPASS, and
so on for DYNAMIC and FILTERS.
Finally, press HOME (SETUP), press the soft key labelled Delay/Gain and set the delay and gain to
zero values.
Press HOME (SETUP) again, and the unit is ready to use and set to provide a flat response.
This method is fast, but has the disadvantage that when the BYPASS function is deselected for a given
type of EQ, the previous settings will be restored, which may not be what is required.
ꢀ C. To ensure that each type of EQ is zeroed-out and can be introduced seamlessly into
circuit, follow this sequence:
1
2
Press HOME (SETUP), then select the soft key labelled Delay/Gain. Set delay and gain to zero.
Press GRAPHIC. Press the soft key labelled Menu three times to display the EQ FLAT menu page.
Turn the centre encoder clockwise, then the right encoder clockwise to confirm.
3
Press PARAMETRIC. If parametric EQ sections exist, then press the soft key labelled Menu twice
to display the Remove menu page. Turn the centre encoder clockwise, then the right encoder
clockwise to confirm deletion of the selected parametric section. Repeat these encoder
moves until no sections of EQ remain.

Using the DN9340E Memories
8. STORING AND RECALLING SETTINGS: DN9340E
The DN9340E includes two types of memory location, to provide maximum flexibility in a range of
applications. There are 32 user memories in battery-backed-up SRAM and 32 preset memories in
non-volatile FLASH memory. Recalling settings from either memory type uses the same procedure,
and the user memories can be stored directly from the front panel of the unit. However, the FLASH
memories can only be programmed directly from an external computer. This provides an absolute
safeguard for valuable system settings, particularly in fixed installations.
ꢀ To store settings:
1
Press STORE.
2
Turn left encoder knob to select the destination (U01 to
U32), for example, “U02”.

9. DN9340E AND DN9344E MASTER/SLAVE REMOTE CONTROL
A DN9340E master unit can control multiple DN9340E and DN9344E units as slaves.
For more details on linking units together and remotely control from a
PC, see Section 10.
Note
9.1. Connections
In order to set up a master/slave network Helix system, first connect the units together using the
Ethercon connectors on the rear panel, as shown in Section 10.2.
9.2. Addresses
The network uses a system of addresses to identify which unit is being controlled. The Helix system
supports addresses from 1 to 32. A DN9340E unit has one address and a DN9344E has two
addresses, corresponding to the left-hand pair of channels (Section 1) and the right-hand pair of
channels (Section 2), respectively. The reason for having two addresses to communicate with each
DN9344E is to allow systems to be built up from either DN9340E (two audio channels) or DN9344E
(four audio channels) in any combination. At any time, two DN9340Es can be replaced by a single
DN9344E (or vice versa) without any need to change the addressing of the system.
9.3. Data model
Each Helix unit has a working memory which is the current state of the unit as seen on the front
panel - this also corresponds to the sound that is currently being heard. In addition, there are 32
user and 32 preset memories in each DN9340E and in each pair of channels in a DN9344E.
•
Issuing a store command to a unit will copy the working memory into the selected user
memory on that unit.
•
Issuing a recall command will copy the selected user or preset memory into the
working memory on that unit.
When using remote control, the Master unit holds a local copy of the working memory for each slave
that is connected. This allows fast switching between units being controlled. When the system is set
on-line, the user can choose whether to “Get all” data from the slaves or to “Set all” data from the
master. This allows the settings for up to 64 channels of audio to be stored in a single DN9340E or,
conversely, an “empty” master DN9340E can be connected to a system that is already running and
upload the system data.

Remote Control
9.4. Getting started
Connect the units using the Ethernet ports as described above. Set the comms address for each
slave unit - ignore the master unit for now. It doesn't matter what addresses you use, but each unit
MUST have a unique address (two unique addresses for a DN9344E).
ꢀ On a DN9340E:
1
2
3
Press and hold HOME (SETUP). The left encoder illuminates, to show that it is active.
Turn left encoder to select the SLAVE channel number.
Press HOME (SETUP) to confirm.
ꢀ On a DN9344E:

6
Press SETUP.
Press and hold SETUP.
Use the UP and DOWN buttons to select the channel number for Section 1.
Repeat for Section 2.
Press SETUP to confirm (unit will display password menu).
Exit by pressing SETUP to step through the menu.
ꢀ Setting the master unit on-line:
Once all the slaves have been set up, the master unit can be set on-line. Again, it must have a
communication channel allocated, which must not be the same as any of the slaves.
1
2
Press and hold HOME (SETUP). The left encoder illuminates, to show that it is active.
Turn left encoder to select the channel number for the master unit. Turn the centre encoder
to select MASTER mode. Turn the right encoder to select the maximum number of audio
channels in the system.
3
Press HOME (SETUP) to confirm.
The reason for setting the maximum number of audio channels is to prevent the master unit from
wasting time looking for units that are not present and trying to set them on-line, while allowing the
user to choose any channel addresses that are convenient. For example, a system including two
DN9340Es and two DN9344Es will have 12 audio channels, so set the “Max” value to 12. When the
master unit goes on-line it will search for units starting from address 1. Once it finds the correct
number of audio channels, it will stop searching.
4
5
The unit will now ask you to choose either to “Set All” slaves to the data contained in the
master unit (from the master unit's local copy of the slave data for each address) or to “Get
All” data from the slaves themselves. Use the centre encoder to select which one you want.
Press HOME (SETUP) to confirm. The unit will show a “DETECTING UNITS” page as it searches
and initialises the slaves. The system is now on-line.

selected using the upper touchstrip and units below the line using the lower touchstrip.
The A/B SELECT button can also be used to move between slave channels in the same way as
for normal DN9340E operation.
Note
Pressing and holding the A/B SELECT button provides a fast shortcut to the Comms page from
any of the EQ pages (graphic, parametric etc). If this method is used to access the Comms
page, then the master unit will remember which EQ page was in use when that slave is next
selected for use.
9.6. System naming
To ensure clarity of operation, each slave can be assigned a meaningful name in addition to its
channel name (1A, 3B etc.).
ꢀ To set up the names

At any time, the copy can be aborted by pressing the HOME button.
9.8. Solo Tracking operation
Instead of selecting slaves manually from the master unit, the Helix system can be controlled from
the solo system of Midas Heritage and Legend consoles. The console RS-232 port is connected to the
RS-232 connector (D9) on the rear of the master DN9340E unit using a straight-wired cable (no
crossovers). Once the channel assignments have been configured (see below), pressing a solo button
on the console will automatically select the channel of EQ that corresponds to that console function
onto the master unit, ready to be controlled.
ꢀ To set up the assignment

10. DN9340E AND DN9344E REMOTE CONTROL SETUP
A slave network of up to 32 DN9340E/DN9344E units can be linked together and remotely controlled
from a PC running the Elgar Library Manager and HELIX DN9340E or DN9344E RCS add-in software.
Further details on these commercially available software applications can be found on the Klark
10.1.Overview
To control an equaliser network, the laptop/PC running HELIX RCS is connected to the network in
place of a Master DN9340E HELIX, assuming control of the daisy-chained HELIX units under pre-set
slave addresses. The following options for connecting the laptop/PC to the HELIX unit(s) are
available:
Ethernet:
Covers direct Ethernet, Local Area Network (LAN) or wireless connection,
converting to an RS-232 front panel input via a Lantronix UDS 100 Converter.
Wireless offers increased flexibility during the event set-up, as the engineer can
move around freely with a laptop and adjust the equalisation while listening to the
end effect at any place in the venue.
Serial (option): The optional RS-232 serial connection is via the “PC PORT” on the front panel of
the first HELIX unit. It is possible to connect other HELIX DN9340E/DN9344E units
via the rear Ethernet port(s) when using a serial connection, but note that this will
be slower that using Ethernet.
The following sections describe how to connect the master HELIX RCS laptop/PC to the system for
each option, and the interconnectivity of the HELIX DN9340E/DN9344E units.
Note If Solo Tracking input is required, the first slave HELIX must be a DN9340 and the front panel
RS-232 PC Port must be used, see Page 44.
10.2.HELIX DN9340E/DN9344E unit interconnections
The HELIX DN9340E/DN9344E units in your system can be connected together in a daisy chain, or
each one can be connected to an Ethernet switch or hub.
Note When connecting the Ethernet cable to the rear panel of a HELIX DN9340E or DN9344E unit,
either of the Ethernet sockets can be used.

10.3.Ethernet Connection
For familiarisation purposes, a basic Ethernet connection may be made to a single unit by connecting
the Ethernet cable to either of the unit’s rear panel Ethernet sockets and to the network socket on the
laptop PC or wireless access point (wireless option).
Note For Ethernet connectivity, the HELIX DN9340E/DN9344E units must be operating V4.00 (or
later) host code.
10.3.1 Ethernet connection – standard
Alternatively, you can set up a system involving multiple units. One end of the Ethernet cable is
connected to the network socket of the laptop/PC. The other end is either connected to an Ethernet
socket on one of the HELIX DN9340E/DN9344E units (daisy chain), or an Ethernet switch or hub,
depending on system configuration.
Note If Solo Tracking input is required, the first HELIX must be a DN9340E.
10.3.2
Ethernet connection – wireless option
The system set up for the wireless option Ethernet connection is via an Ethernet cable connected to
the network socket of the wireless access point. From there it can be connected to an Ethernet
socket on one of the HELIX DN9340E/DN9344E units (daisy chain), or an Ethernet switch or hub,
depending on system configuration. The system is then operated remotely from a tablet or laptop
PC.
Note If Solo Tracking input is required, the first HELIX must be a DN9340E.

Configuring the DN9340E for Network Communication
Before you can control the DN9340E from your remote software, there are number of configuration
settings to check on the DN9340E unit(s):
•
First, you must configure the system devices (the laptop/PC and HELIX DN9340E units) to

Operation: DN9344E
14. OPERATION: DN9344E
The DN9344E is designed to be remotely controlled using one of the following methods:
•
•
Remote control from a master DN9340E unit. For details, see Section 9.
Remote control from a PC running the Elgar Library Manager and HELIX DN9344E RCS
add-in software. For details, see Section 10.
•
Relay operation – where DN9344E memories may be recalled using a simple contact
closure mechanism. For details, see Section 15.2.
15. SET UP MENU: DN9344E
15.1.General
The DN9344E provides various set up options for adapting the operation of the unit to best suit your
operational requirements and preferences, as follows:
•
•
•
•
•
Comms channel setting for remote control operation (Page 1)
Password Page (Page 2)
Analogue/Digital input source and clock reference options (Pages 3 and 4)
Digital output clock reference options (Pages 5 and 6)
Ethernet settings for remote control operation (Pages 7 and 8)
These options are programmed in the Set Up menu and are described below in menu order.
ꢀ To access the Set Up menu pages
ꢀ
ꢀ
At the Home page press and hold the SET UP button to open the menu.
Press the SET UP button repeatedly to step through the pages in turn.
Note that this menu does not ‘cycle’. On completing the set up, the menu returns to the Home page.
15.2.Remote Comms channels (Page 1)
The Comms page lets you select the communications channel on which the unit will send/receive data
to/from a controlling PC or master DN9340E unit. Note that each DN9344 has TWO independent
communications channels (one for Section 1 and one for Section 2) as it contains the equivalent of
TWO DN9340 master units.
Note that when using Ethernet communication, you will need to set up the unit’s IP address and
Subnet mask before selecting the comms channel, see Section 15.6 for further details.
In addition, this menu provides the option to enable the DN9344E for relay operation. This allows
memories to be recalled using a simple contact closure mechanism.

Operation: DN9344E
ꢀ To select a remote communications channel
1
2
Press and hold the SET UP button to open the Comms menu. Note that the red alphanumeric
displays are now showing Last Recalled Memory and Communication (COMMS) mode. The
blue display mode indicator illuminates to emphasise this fact. The UP and DOWN buttons
illuminate to show that they are now active.
Press UP and DOWN on the left-hand half of the unit (Section 1) to select the desired
communications channel. There are 32 possible channels available. Each unit (including the
master) MUST have a unique channel number or the system will not work correctly.
3
Now press the UP and DOWN buttons on the right-hand half of the unit to select its own,
independent communications channel. The reason for having two separate channel numbers
within one unit is that the DN9344E is seen by the system management software as
representing two individual DN9340E units, each with two channels. This allows DN9340E
and DN9344E units to be freely swapped in and out of the system without changing the
mapping between audio channels and communications channels. In other words, every
stereo pair of audio channels has a communications address, irrespective of whether it is a
DN9340E or half a DN9344E.

5
Press SETUP to confirm (unit will display password menu).
Press SETUP to exit.
The red alphanumeric displays are now showing the three-character name for each audio channel.
These are set from the master unit. If no names have been entered, the display will show “---”
