Each system template automatically sets the operating and control mode of the channels and
their settings, including the stereo linked group they pertain to. Example: in a stereo input or
output configuration, the settings applied to the left channel are also automatically applied to the
right channel, and vice versa
User presets: 20
Editing names (labels) of inputs, outputs and user presets
Three front panel locking modes, with password protection: total, with the exception of
MUTE/VOL for inputs and outputs, or with the exception of MUTE/VOL of outputs and activation
and input levels
3. INSTALLATION
The DAM614 can be mounted in a standard 19” rack (482.6 mm) taking up one height unit
(44 mm).
For professional use it is recommended to place the processor in the same rack as the power
amplifiers.
Given the small power consumption of the unit, no ventilation is required. Nevertheless, it is
advisable not to expose the unit to extreme temperatures as well as ensure a dry and dust-free operating
environment.
It is important not to place the processor next to electrical noise sources such as transformers,
voltage dimmers, motors, etc. or their mains supply cables. The metal cover of the device should never
be removed under any circumstance for that same reason.
The DAM614 operates with alternate current (AC) between 90 and 264V at 47 to 63Hz. This
device features an oversized power supply which adapts itself to any mains voltage around the world,
without the need of manual adjustment.
Even though the noise produced by powering up is minimum, it is always advisable to follow this
power up sequence: signal sources, mixing unit, processor and, finally, power amplifiers. The power
down sequence must follow exactly a reverse order. By closely following this sequences, all peaks or
transients produced by switching on and off devices do not affect the next devices in the chain and, of
course, never reach the loudspeakers, which are extremely sensitive about this.

7
Ground Loops
Care should be taken, so that the different mechanical and electrical grounds, as well as the
chassis and ground connections arriving to the device, to be independent from each other.
Ground loops can be easily detected through a low frequency hum noise (50Hz). Depending
on the level of this noise, it can interfere on the music quality.
Audio connections
Usually, many people do not care enough about the quality of cables. Many times, because of a
bad connection or bad quality cables, there can be important problems during the music reproduction.

4. FRONT PANEL
INPUT 1 minijack connector
Stereo INPUT 1 has a duplicate input connector, for the convenience of use: dual RCA on the
back panel and stereo minijack on the front panel.
INPUT encoders and indicators
The INPUT 1 to INPUT6 knobs are digital encoders to be pressed or turned to offer various
functions. Pressing them allows you to enable/disable each input for the output zone currently displayed
on the LCD (ZA, ZB, ZC or ZD). The active inputs (LED on) are mixed and sent to the destination zones,
after a DSP processing adjusted in the unit (volumes, tone adjustment, PAGER/DUCKER type priorities,
etc.).
To enable or disable inputs for a given zone:
1. Briefly press one of the four ZONE A, B, C or D digital controls, in the OUTPUT section of
the front panel
2. The LCD will display the selected zone in its upper left corner (ZA, ZB, ZC or ZD)
3. The INPUT 1 to 6 LEDs will show the inputs that are enabled for this zone (lit = enabled
input)
4. Briefly press any of the INPUT encoders to enable/disable the corresponding input for this
zone
Note: the INPUT 3 to 6 encoders are linked if you select the stereo mode for inputs 3&4 and/or
5&6: their LED indicators simultaneously light up and off when pressing one of them, indicating
that this is a stereo pair (L-R) in which both will receive the same processing for level, EQ, etc.
Rotating one of these controls in this output display screen adjusts the mix level of the
corresponding input in the targeted output, in order to configure a custom mix of inputs for each output.
See section 6.2 for more information (MIXER mode).
The INPUT 1 to INPUT 6 encoders, in combination with the SHIFT key (press and hold encoder +
IN key)also provide access to the input setup menu (see chapter 7).

9
OUTPUT encoders and indicators
These four controls, one for each of the outputs (ZONE A, B, C or D), allow you to:
Short press: select an output zone to be displayed on the LCD. Successive presses of the
same output control alternate the display between two options:
oOutput volume: zone indication, ZA, ZB, ZC, ZD + horizontal bar graph indicating
the output volume In this screen, turning the encoder adjusts the output volume of
the displayed zone.
oMIXER Mode: displays the mix levels of all the inputs for the displayed zone. In
this screen, turning the input encoders allows to adjust the mix level of each input
for the displayed zone.
Long press (> 2 seconds): enable/disable the MUTE feature of an output. The output LED
indicator shows the status of its MUTE function (lit red = MUTE ON). You can press
multiple keys simultaneously to enable/disable their MUTE function
Additionally, when an input, output or global parameters editing/setup screen is displayed, any of
the four output encoders allow you to modify the value of the parameters currently displayed on the LCD,
increasing or decreasing the value depending on the direction of rotation.
NOTES:
The A&B and/or C&D keys are linked if you select the stereo mode for any pair of outputs:
they simultaneously light up and off when enabling/disabling their MUTE mode or setting
the VOLUME, indicating that this is a stereo pair in which both will receive the same
processing for level, EQ, etc.
The DAM614 automatically manages the routing of mono or stereo inputs to mono or
stereo outputs:
oA mono input is directly sent to a mono output, with its corresponding adjustment
of send or mixing level, which is independent of the levels for the other inputs or
outputs
oA mono input is duplicated to be sent to the left and right channels of a stereo
output, with its corresponding adjustment of send or mixing level, which is
independent of the levels for the other inputs or outputs
oA stereo input is sent to a mono output as a mono sum of its left and right channels
(stereo-to-mono conversion), with its corresponding adjustment of send or mixing
level, which is independent of the levels for the other inputs or outputs
oA stereo input is sent to a stereo output, respecting the stereo image between the
two: the left channel of the input will be sent to the left channel (odd) of the output,
while the right channel of the input will be sent to the right channel (even) of the
output, with its corresponding adjustment of send or mixing level, which is
independent of the levels for the other inputs or outputs

LCD display
Display showing digital and text data for inputs, outputs and setup menus, device settings and
information.
Setup keys
The four front panel setup keys allow you to navigate through the various menus and their pages,
and access special features thanks to certain combinations of keys pressed simultaneously:
The left and right MENU keys (5, 7) allow to scroll through the different pages of the unit's setup
menus.
The PARAMETER key allows, within a menu and a page, to select the parameter whose value
has to be modified with an encoder: the name of the targeted parameter flashes in the display while its
value can be edited.
The special combinations of the setup keys are:
Left and right MENU simultaneously for 2 seconds: access to the unit's setup menu (see
chapter 9) as well as the front panel locking/unlocking and password management (see
chapter 10)
SHIFT + left MENU (EXIT): return to the main screen, from any menu
SHIFT + right MENU (CANCEL): undo the last parameter editing and recall the value as

SP/CLIP indicator light
The front panel LEDs indicates two types of information:
Green light or SIGNAL PRESENT (SP): warn of the presence of signal at the mixer inputs.
These indicators illuminate when the input signal exceeds -40dBV.
Orange light or CLIP: light up when the signal level is close to actual clipping, +12 dBV. You
must take care that these indicators do not remain continuously lit with the musical program
you use.

5. BACK PANEL
The back panel features the following connections:
Mains, fuse and power switch
Due to the switched mode power supply, the operating voltage range is 90V – 264V AC, with a
frequency between 47Hz and 63Hz. Before powering up the unit, make sure that the DAM614 is
correctly connected to ground in a facility that complies with local regulations.
Input and output connectors
The DAM614 has the following audio input connections:
INPUT1 to INPUT2: unbalanced stereo connection, with 1/8" jack on the front panel (only
INPUT1) and dual RCA on the rear panel. They're designed for -6 dBV and 0 dBV nominal
signals, an internal jumper allowing to adjust the sensitivity (see section 12. SETUP
DIAGRAM). They can receive signals from CD players, radio tuners, mixing consoles, media
players, audio outputs of computers and tablets, etc.
INPUT 3, 4, 5 & 6 (MIC/LINE): dual (MIC/LINE) balanced Euroblock type connections on back
panel, designed for a signal level between -30 dBV and 0 dBV (LINE level), or between -20 dBV
and -50 dBV (MIC level), with an ADJ control to adjust the sensitivity. They can operate
independently (mono) or be linked as a fourth stereo input for the unit, depending on the
operating template or preset selected from the unit's preset recall menu, EclerCOMM Manager
application software, a wall panel remote control, etc.
Note: turntables CAN'T BE DIRECTLY CONNECTED to this unit because none of the inputs has
a RIAA preamplifier.
The DAM614 signal output is performed through four balanced 3-pin Euroblock connectors
(ZONE A, B, C and D).
PAGER connector
Allows the connection of a MPAGE4 console (optional) to send voice messages with zone
selection in real time (paging).
The connected console will use the INPUT6 channel, in LINE mode, for the management of the
PAGER function (see the MPAGE4 console manual for more details).
You need to correctly setup the PAGER mode for Input 6 to enable this feature, from the device
setup menu (front keys and LCD display) or from EclerCOMM Manager application software (see
chapter 7 for more information).

13
REMOTE connectors
The REMOTE connectors 1 to 4 allow you to control, from a WPm series wall panel or similar (0-
10VDC), the volume of one or several inputs, or the volume of one or several outputs simultaneously, to
select presets, sources for one or several zones and control the volume sent to these zones etc. The
inputs or outputs controlled by each REMOTE port are selected using either the device setup menu
(front keys and LCD display) or EclerCOMM Manager application software (see chapter 9 for more
information).
The WPm series wall panels must be configured with their internal jumpers in 10V / LIN position.
MUTE connector
The rear panel MUTE connector allows the connection of an external potential free contact
closure to mute one or several output zones of the device, when an external unit is activating it
(example: a central alarm system for emergencies and evacuation). The MUTE port affects the outputs
selected from the device setup menu (front keys and LCD display) or from EclerCOMM Manager
application software (see chapter 9 for more information).
RS-232 port
The RS-232 serial communication port allows remote management of DAM614 from a computer
or external control system supporting theCA-NET protocol, or from the free EclerCOMM Manager
application software.
See the manual of the CA-NET protocol for complete information about the details of the
connection and the syntax of supported commands.
The specifications of the DAM614 serial connection are
oBaud rate: 9600 (Fixed, without auto-negotiation)
oData bits: 8
oParity: None
oStop bits: 1
oFlow control: None
oCable: standard RS-232 type, DB9-DB9 (pin-to-pin)

6. MAIN SCREEN/MIXER MODE/PRESET MANAGEMENT
6.1. MAIN SCREEN
After power on, the screen of the device displays the following information for a few seconds…
D A M 6 1 4
L O A D I N G . . .
…then shows other information similar to this one:
Z A O U T P U T 1
P 0 1
The information available on this screen, or main screen, is as follows (according to the example
above:
ZA: selected output zone for volume adjustment, selection of sources, etc. The available
zones are ZA, ZB, ZC, ZD (all mono) or ZAB and ZCD if any pair of outputs is configured
as a stereo zone
OUTPUT 1: name of the output zone, by default OUTPUT n, but it is editable
P01: number of the active preset or template. An asterisk to the right of the preset number
indicates that this preset has been modified and not yet re-saved in the DAM614 memory
(your changes will be lost when you shut down the computer if they are not saved
before…)
Horizontal Volume Bar: displays the output volume of the relevant zone; it can be directly
altered by rotating its digital encoder. The LED indicator of the targeted output briefly
flashes when its level is altered by rotating the digital encoder.
When a unit's input or output has been assigned to a volume control from an external wall panel
(WPm series or similar) connected to a REMOTE port of the DAM614 back panel, any modification of
the physical remote panel position will briefly display the relevant volume setting on the LCD screen
(before returning to the previous screen):
R E M O T E 2

15
In addition, the input and output LED indicators light up on the front panel to give the following
information:
Inputs:
Input enabled for the output zone displayed on screen (LED On). A short press on the
encoder switches its status (active/inactive)
Input disabled for the output zone displayed on screen (LED Off). A short press on
the encoder switches its status (active/inactive)
Outputs:
Muted Output (MUTE = ON) (LED lit in red). A long press (> 2 seconds) on the
encoder switches its status (unmuted/muted)
Unmuted output (MUTE=OFF). A long press (> 2 seconds) on the encoder switches
its status (unmuted/muted)
Note: you can press multiple encoders simultaneously to enable/disable their MUTE
function
6.2. MIXER MODE
From the main screen of a zone (indicating its name and its output volume with a bar indicator), a
short press of this output digital encoder switches your display to the MIXER mode:
Z I1 I 2 I 3 I 4 I 5 I 6
C 9 9 5 0 5 0 6 4 9 9 7 4
In this mode, it displays the mixing level of each input for the output displayed in the main screen
(and in the upper left corner of the MIXER mode screen).
In the example above, we see the following information:
The displayed output zone is ZONE C
The mixing level of the inputs for this zone is 99 (INPUT1), 50 (INPUT2), 50 (INPUT3), 64
(INPUT4), 99 (INPUT5) and 74 (INPUT6)
This mix levels, concerning the inputs routed to the output ZONE C, are totally independent of the
mixing volume of the same inputs for the 3 other zones of the device (A, B and D).
In this screen, you can change these mixing levels by rotating each input digital encoder. The
LED indicator of the targeted input briefly flashes when its level is altered by rotating the digital encoder.

16
NOTES:
Inputs, regardless of the mixing level shown in this screen, must be enabled (LED
indicator lit in blue) for this zone mix to be effective. From this screen or from the zone volume
main screen, you can press input keys to enable or disable the corresponding inputs in the
mix
From the MIXER screen, short presses on the same digital encoder (for the displayed
output) will alternate between the MIXER screen and the main screen of the zone
From the MIXER screen of a zone, you can switch to the MIXER screen of any other
zone, briefly pressing a front panel ZONE encoder (A, B, C or D)
6.3. RECALL PRESET MENU
The DAM614 has 9 operating templates, which are used as a starting point for the configuration
of an operating mode
oT1: 4 stereo inputs x 4 mono outputs
oT2: 4 stereo inputs x 2 stereo outputs
oT3: 4 stereo inputs x 1 stereo output + 2 mono outputs
oT4: 3 stereo inputs + 2 mono inputs x 4 mono outputs
oT5: 3 stereo inputs + 2 mono inputs x 2 stereo outputs
oT6: 3 stereo inputs + 2 mono inputs x 1 stereo output + 2 mono outputs
oT7: 2 stereo inputs + 4 mono inputs x 4 mono outputs
oT8: 2 stereo inputs + 4 mono inputs x 2 stereo outputs
oT9: 2 stereo inputs + 4 mono inputs x 1 stereo output + 2 mono outputs
Each system template automatically sets the operating and control mode of the channels and
their settings, including the stereo linked group they pertain to. Example: in a stereo input or output
configuration, the settings applied to the left channel are also automatically applied to the right channel,
and vice versa
It is therefore possible to recall one of these templates, to edit its parameters and save the
resulting setup as a PRESET or user memory.
System templates are displayed on the screen with the Txx prefix, where xx is the template
number (between 01 and 09), followed by its name or LABEL. These files are not rewritable.

17
User presets are displayed on the screen with the Pxx prefix, where xx is the preset number
(between 01 and 20), followed by its name or LABEL. The default name of all the user presets is USER
PRESET, but it can be modified when you save one of them in memory.
The procedure for recalling a preset or a user template is the following one:
From the main menu, briefly press SHIFT + RECALL
The RECALL PRESET message is displayed and a preset number is flashing
R E C A L L P R E S E T
[ T 0 2 ] 2 S T + 4 M X 1 S T + 2 M
Select the preset or template using an encoder (ZONE A. B, C or D), and then select one
of the two following options:
Press SHIFT + RECALL to validate the selection and activate the new preset,
returning to the main screen, this time with data from the new active preset
Or
Press SHIFT + CANCEL to cancel the selection and display again the preset from the
selection list
Pressing SHIFT + EXIT at any point during the above process cancels the selection and returns
the main screen.
6.4. SAVE PRESET MENU
Once you have edited the active preset or template, the procedure to save the current
configuration in a user preset memory is the following one:
From the main menu, press SHIFT + SAVE for at least 2 seconds (long press)
The SAVE PRESET message is displayed and a preset number is flashing
S A V E P R E S E T
[ P 0 7 ] S T E R E O L I V E 3 W
Select the user preset using the rotary control, and then select one of the two following
options:
oPulsar SHIFT + SAVE para validar la selección
Or
oSHIFT + CANCEL para cancelar la selección y mostrar de nuevo el preset de
partida

18
Pressing SHIFT + EXIT at any point during the above process cancels the selection and returns
the main screen.
If the selection is validated (SHIFT + SAVE) the following screen is displayed, allowing you to
rename the destination preset:
R E N A M E P R E S E T
[ P 0 7 ] S T E R E O L I V E 3 W
To rename the preset:
Edit the first character with an encoder (ZA or ZB)
Press PARAMETER to select the next character to edit
Select the new character with an encoder
Etc…
Pressing SHIFT + CANCEL cancels the previous changes and the display returns to the
original state
Once all the desired characters are edited, confirm the changes by pressing SHIFT +
SAVE, displaying the PRESET SAVED message for a few seconds. The preset is stored
in memory, but is not selected as active preset by the fact of having been saved
The main screen returns, showing again the current preset at the time, and it is not
necessarily the newly saved preset
Pressing SHIFT + EXIT at any point during the above process cancels the selection and returns
the main screen.
The parameters stored in a preset are:
All the input and output settings, including their names (labels)
The setup for REMOTE ports 1, 2, 3 and 4 and the MUTE port (allowing to mute outputs
via an external contact closure)

19
7. INPUT EDIT MENU
To open the edit menu for the settings of an input, you have to press SHIFT + INPUTn, INPUTn
being the encoder corresponding to the desired input (1, 2, 3, 4, 5 or 6).
Once in the edit menu for an input, and in one of its pages, you can obtain the same page for
another input by pressing SHIFT + INPUTm, INPUTm being the encoder for the new targeted input
The new edited values are activated in real time. You can cancel an edit operation, returning the
value before editing, by pressing SHIFT + CANCEL.
To exit the Edit menu and return to the main screen:
Press SHIFT + EXIT
Press SHIFT + INPUTn (the MUTE key of the input n currently edited)
Stay 2 minutes without operating any control on the front panel
The next pages show the full structure and options of the menu for setting inputs.
NOTES:
1. INPUTs 3, 4 5 and 6 are dual (MICRO/LINE), and feature additional setup menus
compared to inputs 1 and 2 (which are only LINE inputs):
oHigh-pass filter (HP FILTER), with adjustable cut-off frequency between 50 and
150 Hz
oTALKOVER: priority function of an audio input over other audio inputs
oNOISE GATE. When this function is turned on, the input remains muted as long as
no signal exceeds the activation threshold of the NOISE GATE, rejecting the
background noise picked up by the microphone or the connected device
oFEEDBACK SUPPRESSOR. It's an efficient system to reduce the risk of feedback
loops (audio feedback or Larsen effect) when a microphone source is near the
speaker(s) producing its signal, once amplified. When activated, this function
slightly shifts the incoming signal frequency on the affected channel before
sending it to the matrix mixer and then to the selected output. The shift is so slight
that it is barely noticeable to the listener, especially when it occurs in the frequency
range of the human voice. A few cycles (Hz) displacement is enough to greatly
increase the system protection against possible feedbacks.

20
The adjustable parameters for the TALKOVER function are:
oActivation (ON/OFF)
oMODE: DUCKER/PAGER (the latter only for Input 6). It has two operating modes:
DUCKER: performing after a signal detection (when the signal exceeds the
detection threshold), it attenuates the signals that are assigned to the
affected outputs (DUCKED OUTS)
PAGER (only Input 6): allows messages to be sent in real time from a
MPAGE4 desktop paging station with a microphone
oPriority (PRIO): HIGH/LOW. An input featuring a TALKOVER function will be able
to attenuate or mute the other inputs, with lower priority or without Talkover
function, that are routed to the destination zones defined in its setup. If several
inputs have the same priority level (several inputs with Talkover LOW or HIGH),
the first input whose Talkover is engaged on a destination zone (its signal
exceeding the detection threshold) disables the Talkover of the other inputs for the
same zone, until the end of operation of the first Talkover (when its signal drops
back below the activation threshold). Then the Talkover function is available again
to be activated by an input that exceeds the threshold
oAttenuated Outputs (DUCKED OUTS): outputs affected by the TALKOVER
function when this one operates in DUCKER mode. The symbol "o" under one of
the zones on the screen indicates that this zone will be affected by DUCKER
function
oActivation threshold (TLK THRESHD): trigger threshold of the Talkover function.
The signal of the relevant input activates the Talkover function when it exceeds
this threshold. This trigger level depends on the sensitivity setting for the input on
the rear panel, but it is independent of the INPUT VOLUME adjustment made on
the device (only available in DUCKER mode, since in PAGER mode the function is
activated by pressing the PAGE button on the MPAGE4 console)
oAttenuation (DEPTH): attenuation applied by the function, when triggered, on the
rest of the signals sent to the affected zone)
oAttack Time (ATTACK): the time it takes the Talkover function to act from the
moment the signal exceeds the trigger threshold
oHold Time (HOLD): time during which the Talkover function remains active, once
triggered and once the signal falls back under the trigger threshold (only available
in mode DUCKER, since in PAGER mode the function remains active as long as
the PAGE button is pressed on the MPAGE4 console)
oRelease Time (RELEASE): time that it takes the Talkover function to stop
performing, progressively recovering previous levels of input signals for the
affected zone, after the Hold time
oChime melody or "ding-dong" + playback volume: brief melody that plays when the
Talkover function is activated, in PAGER mode only (two melodies are available)
