9. Power Supply
The unit is expected to work with 230 VCA –
50/60 Hz distribution system.
In case of power dysfunction, check the outside
protection fuses and eventually replace them with
others of same calibration; if one of them burns
out immediately, do not go on and have check the
unit by qualified personnel.
Take away plug from 230 VCA electric power
socket always, before removing fuses and, in any
case, open the unit framing.
10. Connections
10.1. General criteria
In order to allow the equipment to work correctly,
it is advisable to comply with a number of general
criteria when making the connections:
•Avoid positioning cables or microphones on
the cabinet of the equipment.
•Avoid laying the signal lines parallel to the
power-supply lines. Keep a minimum distance
of 30/40 cm.
•Position the input lines and the output lines at
a distance from one another.
•In order to avoid acoustic feedback (the
Larsen effect), position the microphones out
of the angle of coverage of the loudspeakers.
10.2. Balanced Mic / Line Inputs
The 5 female XLR input sockets (22) for the mic /
line level signals are located on the rear panel of
the equipment. The figure Fig2. shows the
connections to these sockets. These inputs are
electronically balanced.
The mic / line sensitivity could be selected through
the multi-micro switch (21) placed on the left of
the socket.
48Vdc “phantom” supply could be joint to each
socket (on the same balanced phonic line),
through the multi-micro switch (21) placed on the
left of the socket; therefore, before connecting a
microphone it should pay attention to the model (if
dynamic or electret). In case of dynamic
microphone do not insert 48 VCC; insert it with
electret microphone only.
10.3. Direct Out
The male XLR direct output socket (31) for the
preamplified signal not DSP processed are
located on the rear panel of the equipment. The
figure Fig2. shows the connections to this socket.
This output is electronically balanced.
The output signal level could be adjusted through
the potentiometer (32) placed on the right of the
socket.
10.4. Pre Out 1 / Pre Out 2
The 2 male XLR output sockets (24-25) for the
preamplified signal DSP processed are located on
the rear panel of the equipment. The figure Fig2.
shows the connections to these sockets. These
outputs are electronically balanced.

10.5. CD / AUX
The 2 couple of mono female RCA input sockets
(29-30) for the CD and AUX sources are located
on the rear panel of the equipment. These inputs
are unbalanced.
These 2 inputs are alternatively selected by a
switch (3) located on the front panel.
When the CD input is selected by the switch
located on the front panel, the AUX input is
directly mixed with the other inputs for allows the
connection in cascade of an external mixer’s Pre
Out in the way to expand the system input
capability. This feature could be deactivate
following the indications described in the Fig6.
10.6. REC
The couple of mono female RCA output socket
(28) for the REC preamplified signal not DSP and
3 band EQ of each channel processed is located
on the rear panel of the equipment. This output is
unbalanced.
10.7. Remote / Priority
The female RJ45 socket (26) for the remote
control are located on the rear panel of the
equipment.
The Priority function is also available on the 2 pole
phoenix-type (27) connector located on the right
of the socket. The Priority function could active
the chime if C714 Din Don optional card is used.
The remote master volume level control for each
output channel is available if the C656-RJ Remote
control optional cards is used.
The remote control and priority functions are
deeply described in the chapter 12 advanced
functions.
User’s Manual 8 17
10.8. Power Output
The device is provided with a multi-way power
output terminal strip for constant-voltage
distribution (50, 70, 100 V) and low impedance (4
Ohms ) systems (20-23).
Constant voltage lines
50, 70, 100 V terminals should be used with each
loudspeaker equipped with impedance-matching
transformers and parallel connected. This fact
makes the system easy to create and, if any of the
loudspeakers should be disconnected from the
line for any reason, the rest of the system would
continue to function properly. The figure Fig3.
shows the connections of the line to these
sockets.
In order to achieve the maximum efficiency of the
system and to take precautions from amplifier bad
working, it is necessary to check the effective total
power handling of the loudspeakers that has to be
equal or lower than the RMS power value of used
amplifier. It’s a good rule arranging a 10-20%
safety margin on the amplifier power capability.
Constant impedance lines
4 Ohms terminal should be used.
In order to achieve the maximum efficiency of the
system and to take precautions from amplifier bad
working, it is necessary to check the effective
loading impedance of the lines. The total speakers
impedance should be equal or higher than pre-
selected value for connection.
To get that, each loudspeaker should be without
impedance-matching transformer and should be
connected in series or in series-parallel groups; In
any case loudspeakers should also have the
same power handling. The figure Fig4. shows the
connections of the line to these sockets.

11. Protection Systems
In addition to the usual protection consisting of
fuses, these products are complete of different
protection devices in order to safeguard them
from possible risks of damage. Protection
conditions are signalled by the fact that the PROT
(6) signalling lamp located on the front panel of
the equipment will light (Short Circuit excluded),
the unit will stop working and only the fan will
continue to run.
11.1. Power Output Short Circuit
Applying a lower loading impedance than the
rated value means requiring the equipment to
supply a power higher than it can do on a
continuous basis.
In order to avoid this problem, the units are
equipped with a circuit protecting them against
overloads that protects automatically.
The protection circuit will be tripped immediately
on the amplifier if any of the following cases
occurs:
•Short circuit on one of the loudspeaker
outputs.
•Loading impedance less than 50% of the
rated value.
•power required of the loudspeaker system
connected to the constant-voltage lines higher
than the power that the amplifier is able to
deliver.
Overload conditions are signalled by the fact that
the unit doesn’t supply any amplified signal at the
power output.
The equipment will resume normal operation after
a power cycle as soon as the cause of the
overload has been eliminated.
11.2. Turn On / Turn Off Delay
A mute circuit with relay, with a delayed starting
up and immediate power turning off, has been
inserted in order to avoid the switch-on/turn-off
transients that may cause damage to the
loudspeakers.
11.3. Power Unit Over Temperature
The thermal protection is of the self-resetting type,
and is tripped when the equipment reaches an
excessively high temperature.
This may be due, for example, to the fact that the
ambient temperature is too high or to the
insufficient ventilation of the rack cabinet.
The equipment will resume normal operation as
soon as the cause of the temperature overload
has been eliminated.
11.4. Power Supply Over Voltage
The A.C. voltage is monitored; if its value does not
fall within the correct running range (over voltage)
the supply will be automatically blocked. The
amplifier will restart when the main supply voltage
is under the maximum running voltage.
11.5. Power Supply Soft Start
The units are provided with a soft-start system to
reduce the inrush current when switched on. This
feature is particularly useful in multiple devices
installations.
12. Advanced Functions
12.1. Noise Gate
A Noise Gate circuit has been inserted for each
input channel in order to minimize the background
noise on the output when no signal is applied at
the input. The channel opening threshold could be
adjusted through the controls (1) located on the
front panel of the equipment. The Fig6 shows
available internal setting for the noise gate circuit.
12.2. Remote
The remote master volume level control for each
output channel is available if the C656-RJ Remote
control optional cards is used. The figure Fig6.
shows the C656-RJ insertion operation.
Connection with the female RJ45 socket (26)
must be via shielded cable without section
limitations for distances up to 150 mt. The figure
Fig5. shows the connections to these sockets. An
external pot (10K) can be connected for remote
master volume level control for each output
channel or a switch for the mute control. The
external pot is governed by the master level of the
amplifier allowing the installer to set the volume,
then lock the amplifier in a rack, leaving the user
with just a master volume control that cannot go
beyond the level set on the master control.

12.3. Priority
A priority circuit has been inserted in order to
softening one or more setted input channels by
the priority control in accord with the system
requirements.
Internal jumpers are provided to assign muting of
the channels independently. From the factory,
muting is assigned to all input channels.
The figure Fig6. shows the instructions to assign
the muting of the channels.
A Normally Open input is available on the Remote
RJ45 socket (26) and also on the Priority 2 pole
phoenix-type connector (27) for the connection of
paging microphone with priority control or to be
controlled from external devices.

13. Advanced Functions - DSP Section
13.1. Programmable settings („Presets“)
The DSP combines numerous integrated
functions with very simple operation. Even in
acoustically difficult environments, best results are
achieved. So-called „Presets“ can easily be
programmed. No less than 20 of these preset
slots enable programming for any application and
make them available to the user at the touch of
one’s fingertips.
For each preset, the following 3 parameters are
programmed:
•master volume
•which of the 2 outputs are to be active
•preset name.
This way the different settings are immediately
distinguishable.
13.2. Changing between presets
•Turn the unit on with the main on/off switch
located on the front panel.
•The welcome message will appear in the
display. After a few seconds, it will disappear
again and the settings of the current preset
will show up. Below, an example is given.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•Here one can see the current preset name (in
this case „Preset 1“) as well as the value of
the master volume in percent (total output
volume, here 70%). The bar above the preset
name is an analogue representation of the
master volume.
•On the right-hand side of the display the two
little squares represent the 2 outputs (the
numbers 1 through 2 are written above and
below the display). A dot within a square
indicates, that this particular output is active.
•Please note: The preset settings can be
guarded against accidental changes. In this
„Vol/Preset protect“, changes can only be
undertaken by pushing and turning a knob at
the same time.
•In order to switch from one preset to another,
push the preset knob while turning it until the
desired preset shows up in the display; then
let go. Now, all is set for the next application.
13.3. Temporarily changing on existing
preset
•Should it become necessary to change the
volume of a given preset, turning the volume
knob to set the desired value. This change is
only temporary, i.e. once the unit is turned off
and back on again, the original preset is
active again. Push the volume knob while
turning it to set the desired value if the
„Vol/Preset protect“ is activated.
•Should it become necessary to temporarily
change the active outputs. By pushing the
preset knob, the display will successively
show each output. The respective name of the
output will appear (in the example given below
„Output1“) as well as a little square next to the
corresponding number of the output. „On“ or
„off“ indicate whether the output is active or
not. This is also reflected in the little squares,
where a dot in the middle indicates an active
output.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•Turning the volume knob by one click, you
can change the output to „on“ (active) or „off“
(deactivated). Briefly pushing the volume knob
will take you one level back, and in the display
you will see the preset name again with its
current settings. These changes are also
temporary, i.e. will only be effective until the
unit is turned off and back on again.

14. Extended Functions - DSP Section
14.1. Programming a new preset
(or reprogramming an existing one)
•This section describes how to programme one
of the 20 preset slots, i.e. give a preset name
and select the desired master volume and
outputs. In the same fashion, existing presets
can be reprogrammed (as opposed to the
temporary changes described in section
13.3.).
•First, turn the unit off with the main on/off
switch in the back.
•Then, turn the unit back on, while pushing
both the volume und preset knobs at the
same time. Keep the knobs pushed until the
parameter menu appears (see below). The
four items „preset“, „parameters“, „config“, and
„service“ appear.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•Briefly push the preset knob. The Edit Preset
windows will appear.
•Briefly push the preset knob. The first preset
will appear („Preset 1“ in case no preset name
has been given so far).
•In case you wish to choose a different preset
slot, briefly push the volume knob. That way
you move back to the Edit Preset menu and
can choose a different preset by turning the
volume knob.
•A yet unused preset slot can be identified by
the fact that it does not yet have given preset
name, but merely „preset“ and a number (e. g.
„preset 12“).
•Briefly push both knobs at the same time.
Again the parameter menu shows up.
•Push the preset knob. Now you can determine
the preset name. The cursor will blink under
the first character.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•By turning the volume knob, the following
letters, numbers, and special characters will
appear in this order: A-Z, Ä, Ö, Ü, a-z, ä, ö, ü,
0-9, space, ! „ # $ % & ’ ( ) * + , - . /
•Pushing the preset knob will confirm the
current character und move the cursor one
position to the right. Now you can set the next
character.
•When you’ve filled in the preset name, turn
the preset knob one click to the right to now
determine the master volume for this preset.
Set the value by turning the volume knob. The
values range from 0 to 100%. The
corresponing value in dB is given in brackets.
•Now turn the preset knob again one click to
the right in order to determine the outputs for
this preset.
•When pushing the preset knob, the 2 outputs
will appear one after the other with their
respective names. „On“, as well as a dot in
the little square, indicate that this output is
active. By turning the volume knob one click,
the shown output can bei either activated or
deactivated.
•Now the programming for this preset is
complete. By pushing the volume knob, you
will exit the programming mode. You will be
asked whether you would like to „Save
changes?“. Pushing the volume button
indicates „yes“ and your changes will be
saved (→„Saving … do not interrupt!“).
Pushing the preset knob indicates „no“ and
the display will show „Changes discarded!“.
14.2. Programming the Mixer
(The parameters menu)
•Functions and settings in the parameter
domain should be changed by qualified
personnel only. The only exception is the
programming of a new preset as described in
section 14.1. .
•The digital control boasts the great advantage
of the programmability of various functions. In
this parameters menu, not only the presets
are programmed, but among others, the
equalizers and the parameters for feedback
elimination are set. In fact, the entire
programming of the DSP is done here with
menu-driven user guidance and merely two
knobs. No PC or Laptop are required.
•In order to enter the parameters menu (and
therefore the programming mode), first turn
the unit off.
The following modifications are to
be performed by qualified audio
technicians only.
Preset 1 Name
[Preset 1 ]
Presets Parameters
Config Utility
User’s Manual 13 17
•Then, turn it back on again while pushing both
knobs (volume and preset) until the parameter
menu with its four items preset, parameters,
config, and utility appear.
•By turning the preset knob, you can change
from one menu item to the next which is
indicated by a small arrow.
•By pushing the preset knob, you choose the
respective item from the menu.
14.3. General comments on programming
the DSP
•Turning the preset knob one click to the right
will always bring you to the next item of a
menu, i. e. to the next parameter to be
programmed. This knob is therefore also
marked „parameter“. For simplicity, we will
continue to name this knob the preset knob.
•Changing a value or character is always done
by turning the volume knob. This knob is
therefore also marked „value“. However, here
too for simplicity, we will stay with the name of
volume knob.
•These knobs are so-called dynamic rotary
encoders, meaning that when slowly turning
one of them, the value will change in small
increments whereas turning a knob by the
same amount more quickly will change the
value superproportionally faster. This enables
a fast but precise setting of the desired
values.
•By pushing the volume knob, you will go up
one level in the menu hierarchy. Whenever
you have changed any parameter, you will be
asked whether you would like to „Save
changes?“. Pushing the volume button
indicates „yes“ and your changes will be
saved (→„Saving … do not interrupt“).
Pushing the preset knob indicates „no“ and
the display will show „Changes discarded!“.
•The following 4 sections will describe the
programming possiblities of the 4 menu items.
For quick reference, there is a table of all
programmable settings at the end (in section
14.8.).
14.4. Presets
•Preset name: Determine the name for a
given preset. The procedure is described in
detail in section 14.1. .
•Preset master volume: Setting the master
volume for a given preset.
•Preset output: Choose the desired outputs
for a given preset. The procedure is described
in detail in section 14.1..
14.5. Parameters
•Briefly push the preset knob. The Edit
Parameterset windows will appear.
•Briefly push the preset knob. The first
parameterset will select.
•In case you wish to choose a different
parameterset slot, briefly push the volume
knob. That way you move back to the Edit
Parameterset menu and can choose a
different preset by turning the volume knob.
•Level: Determine the level for each output.
Set the desired value by turning the volume
knob. Pushing the preset knob will bring you
to the next output. With this indivudual level
setting, you will achieve an optimal balance of
the outputs which remains even when
changing the master volume.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•Delay: It can be set in 1-meter increments
and the corresponding delay time is given in
milliseconds (calculated according to a speed
of sound of 343 m/s, corresponding to a room
temperature of 20 °C). Here, too, pushing the
preset knob will move you from one output to
the next.
•Graph EQ: Set the level of the 31 bands of
the graphic equalizer for each of the 2 outputs
(see picture below). By turning the preset
knob, you will move to the next frequency;
again by pushing it, you will move to the next
output.
VOLUME -50 -36 -30 -22 -15 -9 -3 0dB 1
PRESET 2
•Param EQ 1 Freq: Set the 1st frequency of
the fully parameteric equalizers (range: 20 Hz
to 20.45 kHz). Here, too, the value is set with
the volume knob. Pushing the preset knob will
bring you to the next output, so you can set
the first frequency for each output.

band (range: 0.2 to 100; logarithmic
increments 0.2, 0.22, 0.25, 0.28, 0.32, etc.).
The high Q-factors enable extremely narrow-
band notch-filters for ideal feedback
elimination.
•Param EQ 2-6 Freq: Proceed as described
above for bands 2, 3,4,5 and 6.
•Param EQ 2-6 Gain: Proceed as described
above for bands 2, 3,4,5 and 6.
•Param EQ 2-6 Q: Proceed as described
above for bands 2, 3,4,5 and 6.

PRESET 2
•LCD contrast: Set the contrast of the LCD
display from 0 to 50 for an optimal readability.
•Vol/Preset protect: The protection of the
settings is such that changes (e. g. changing
between presets or temporary volume
changes) can only be performed while
pushing and turning the knobs at the same
time. This is intended to safeguard the
settings from accidental changes. If this
protection is turned off, changes can be made
by simply turning the knobs without pushing
them. Turning the volume knob by one click
either enables or disables the protection.
•Welcome screen Line 1: Set the first line (16
characters) of the welcome text that shows up
when powering up the unit. The cursor will
blink under the first character. By turning the
volume knob, the following letters, numbers,
and special characters will appear in this
order: A-Z, Ä, Ö, Ü, a-z, ä, ö, ü, 0-9, space, ! „
# $ % & ’ ( ) * + , - . / Pushing the preset
knob will confirm the current character und
move the cursor one position to the right. Now
you can set the next character.
•Welcome screen Line 2: Set the second line

15. System SetUp (Step by Step)
The inputs of the mixer can accommodate a wide
range of sources including active paging stations,
dynamic microphones, DVD,CD and Mp3 players
and mixers.
The Direct out and Preout outputs may be used to
drive power amplifiers, mixers, or mixer amplifiers.
The Power output may be used to drive constant
voltage or constant impedance speaker lines.
Each installation will require setting the
appropriate relative mix of levels between paging,
program sources and mic/line inputs for each line
or amplified outputs.
Because of the variation in levels between the
possible sources, the mixer offers a number of
gain stage adjustments and parameter tools so
you can set the correct levels for your application.
Also consider what the outputs are driving….
Setting up correct parameter structure through the
whole system is important to achieve optimal
results.
The following step by step procedure has been
devised to assist during the setup process.
•Connect the speaker lines to the correct
power output socket.
•Select the indicated input sensitivity
(mic/Line)by the dipswitch (21) located on the
back panel, for each input in accord with the
source.
•Active the phantom supply by the dipswitch
(21) located on the back panel if electrect
microphones are used.
•Ensure that all the Gains and Volume controls
are at minimum, and that the Tone controls
are flat.
•Keep the master volume for each output
channel at about 10%÷20%
•Keep the input channels LEVEL (11) at about
5 (50%).
•Adjust each input channel GAIN (2) in order
that the SIG (12) green led lit continuously
also with low input signal and that the CLIP
(13) red led lit with strong input signal.
•Adjust each input channel GATE (1) in order
to avoid the noise gate activation cause
background noise or undesired signal but by
the speaker voice or input signal only.
•Adjust the master volume and the input
channels LEVEL in order to obtain the
required sound pressure.
•Optimize the room equalization and delays in
order to obtain the best intelligibility by the
DSP parameter tools.
•Adjust the 3 band equalizer (8,9,10) for each
channel in order to obtain the best result with
each different input source.
