1POWER
Main switch with LED indicator.
2MASTER
Main level control.
3BASS AND TREBLE TONE CONTROLS
The BASS control is used to adjust the low frequency band, the TREBLE control is used to adjust the high
frequency band. The control’s range is -10 dB to +10 dB for each band. Turning the knob to the right boosts
the corresponding frequency band, while turning to the left attenuates the band. Adjust the controls to
obtain the best intelligibility and equalization for your audio system.
4INPUT 1 – 4 LEVEL
Level controls of the corresponding rear input, which can be either a microphone or a line level device
(see point 17).
5LED INDICATOR
SIG: indicates the presence of an output signal.
-10dB: indicates a normal output level.
CLIP: indicates that the input signal is too high and the amplifier is starting to limit the signal.
PROT: indicates that the amplifier is in protection and no signal will be reproduced from the outputs. The
amplifier may have a shorted output or has overheated due to incorrect use.
ON: indicates that the device is turned on.
For a correct operation, the -10dB LED should light up often and CLIP LED should light up rarely. If the CLIP
LED stays always on, turn down the MASTER level or the corresponding INPUT level control.
6ZONE 1-4 LEVEL CONTROLS
These LEVEL controls set the output volume for each corresponding zone with 6 steps. These controls
operate as attenuators starting from the MASTER LEVEL, so position 5 corresponds to full output while
position 0 corresponds to the zone muted. The attenuation steps are the following:

NOTE: each ZONE LEVEL control acts exclusively on the corresponding 100V ZONE OUTPUT (9).
NOTE: when a paging call is made using the dedicated PA RM4 base, the zone volume controls will be by-
passed and the message will be played at the volume set by the PA RM4 base and by the MASTER control.
7ZONE 1-4 SELECTOR
Using these keys, you can select the zone output where you want to direct audio program.
NOTE: these controls act both on the Zone outputs at 100V (9) and on the zone outputs at line level (11).
NOTE: when a paging call is made using the dedicated PA RM4 base, the zone selectors will be by-passed
and the message will still reach the zone or group of zones selected on the base, temporarily silencing any
background music.

10
8ALL ZONE SELECTOR
Press the ALL button to activate all zones at the same time.
NOTE: this control acts both on the Zone outputs at 100V (9) and on the zone outputs at line level (11).
NOTE: when a paging call is made via the dedicated PA RM4 base, the zone selectors will be by-passed and
the message will still reach the zone or group of zones selected on the base, temporarily silencing any
background music.
9AUX LEVEL
AUX A / B or Media Player (12) input level control.
10 AUX SELECTOR
With the A, B and PLAYER buttons you can choose between the rear auxiliary inputs AUX A or AUX B (4)
or the internal Media Player (12). The corresponding LED indicates the selected input.
Note: only one input at a time can be selected.
11 RACK mounting
The equipment is supplied with 2 adapters for mounting in a 19" RACK cabinet.
12 MEDIA PLAYER
The Media Player allows to play music or other audio contents choosing between FM radio, USB pendrive,

REAR PANEL OPERATIONS

11
13 CHIME ROUTING AND LEVEL
The Chime Routing switches enable the Chime function on the respective INPUT 1 ÷ INPUT 4 (17) inputs:
Examples:
ON – ON – ON – ON - CHIME enabled on all inputs
ON – OFF – ON – OFF - CHIME enabled on inputs 1 - 3 and disabled on inputs 2 - 4
OFF – OFF – OFF – OFF - CHIME disabled on all inputs
With the Chime function enabled on an input, when the respective dry contact closes (17 - C), the
amplifier will reproduce an attention tone from all the loudspeaker lines.
The Chime Level potentiometer set the level of the attention tone.
14 VOX MIC PRIORITY
The VOX PRIORITY ENABLING switches enable the VOX function on the respective INPUT 1 ÷ INPUT 4 (17)
inputs:
Examples:
ON – ON – ON – ON – Vox Priority enabled on all inputs
ON – OFF – ON – OFF - Vox Priority enabled on inputs 1 - 3 and disabled on inputs 2 - 4
OFF – OFF – OFF – OFF - Vox Priority disabled on all inputs
When the VOX circuit of one of the channels with VOX enabled (ON) detects the presence of an audio
signal on the respective input (17), the AUX channels (A, B, media player) and the other channels having
VOX disabled (OFF) are silenced, while all channels with VOX enabled (ON) remain active at the output.
The MIC PRIORITY knob sets the level of the signal that activates the VOX function. Turn it clockwise with
lower input signals, if turned fully counterclockwise the VOX function will be bypassed.
15 REMOTE MIC
RJ45 connector for dedicated PA RM4 microphone base for selected zones, groups of zones and general
calls.
The amplifier accepts up to a maximum of 4 PA RM4 bases connected in daisy chain configuration, with a
maximum full length of 200m of CAT5 or CAT6 net cable. See further for detailed instructions.

12
16 ANT
This is a 9.5mm male antenna connector that accepts the FM antenna supplied with the unit or a 9.5mm
female TV connector wired to an external FM antenna wired with a typical coaxial 75 ohm cable.
Note: the antenna supplied is a simple wire of 140 cm length and to avoid interference it must be placed
distant from other cables and metal objects. If you experience problems with FM radio reception, we
suggest using a 75ohm coaxial cable to place the antenna in a more suitable location.
17 INPUT 1-4
These inputs can be used to connect low impedance dynamic microphones (30-600 ohm), condenser
microphones with phantom power supply and audio sources with line level signal output (e.g. radio
tuners, television receivers, media players, etc.).
a) Use a shielded cable terminated with a 3.5mm pitch Euroblock connector to make a balanced or
unbalanced connection as follows:
Connection of a Balanced line to the INPUT.
Connection of an Unbalanced line to the INPUT.
b) Use the correspondent upper switch to select the type of source connected to the input:
MIC for a dynamic microphone.
PH for a condenser microphone with phantom power.
LINE for a line level source.
c) Each input has two Euroblock terminals with 3.5mm pitch to which a "clean contact" can be connected
(clean means that it is not connected to other elements of the circuit such as GND). This contact is
usually connected to the TALK button present in the microphone bases, which also serves to activate
the microphone. When the contact is closed, two functions are activated:

13
CHIME
When the contact is closed, if the CHIME dipswitch (13) of the channel is in the ON position, an
attention tone will be played by the loudspeaker system.
SILENCING THE INPUTS
When the contact is closed, the AUX input and the other inputs 1-4 that have the respective VOX
PRIORITY dipswitch (14) in the OFF position are silenced. The inputs will remain muted as long as the
clean contact remains closed.
Note: it is advisable to always use microphone bases with TALK button and clean contact, for better
management of the silencing of inputs.
Note: the clean contact will not silence the inputs that have the VOX function activated (ON). For
details on the VOX function, see point 14
WARNING
It is recommended that you set the input level to the minimum before changing the position of the input
selector, to avoid unwanted noises.
Some line level devices do not support "PH" phantom power, which could therefore cause permanent
damage to them, so it is not recommended to activate it when a line device is connected to the input.
18 AUX IN A / B
These are two RCA female connectors that accept two RCA plug from LEFT and RIGHT channels of a line
level stereo source (e.g. radio tuners, television receivers, media players, etc.). Each RCA input is wired
as follows:
Tip = + positive or "hot"
Sleeve = shield or ground
By means of these inputs is possible to use an external source instead the media player inside the
amplifier, selecting it with the front panel switches (10) and adjusting the volume with the AUX LEVEL
potentiometer (9).
19 PRE OUT – AMP IN
These are two RCA female connectors that accept two RCA plug. As standard, the AMP IN input is
connected to the PRE OUT output with a jumper.
It is possible to optimize the signal to be amplified by inserting between the two terminals an external
processing unit, typically a graphic equalizer, to optimize the spoken words intelligibility. For the
connection refer to the figure.

14
20 REC OUT
These are two RCA female connectors that accept two RCA plug This is an unbalanced output that can be
used for recording or to connect other amplifiers. Please note that both left and right connectors have the
same audio content, so each one can be used also as mono output.
21 ZONE LINE OUTPUTS
The device has 4 line-level zone outputs for connecting additional zone amplifiers.
Use the balanced connection with booster amplifiers equipped with balanced input:
Use the unbalanced connection with booster amplifiers with an unbalanced input:
22 GENERAL LOUDSPEAKER OUTPUT
This is a 5.08 mm pitch Euroblock connector. This connector can accept 0.5÷2.5 mm2/ 20÷14 AWG size
cables, a Class 2 wiring is needed for fixed installation.
