IV. Installation and connections
WARNING !
The device must not beexposed to falling water and splashing water.The device must imperatively be connected
to a power supply socket with earth conductor. Do not obstruct the ventilation openings.
1. Input Jack 6.35mm connection (front panel)
The use of a stereo jack allows a balanced signal to be connected to the "MIC1" input present in zone (2) on the
front panel.
With Jack 6,35mm mono : T = hot point, S = ground (in this case of unbalanced
connection, the output signal will be attenuated by 6dB).
2. Power connection
Use the mains cable supplied with the product and plug it on the plug of the zone (1).
If a 24V battery power supply is chosen, connect the battery to the 2-point input of the zone (2).
3. Speakers‘ lines outputs connection
Connection must be made on zone (2) or (3) connectors.
Each of the outputs is accessible via a 2-point screw terminal block.

To use PGM-1247-V2 dedicated console, connect its RJ45 `` COM 01 '' output (shown below in zone (2)) with an
RJ45 cable to the RJ45 input `` Paging '' at the back of the mixer amplifier in zone (7).
It is possible to connect up to 10 consoles as indicated below (maximum wiring distance between the first and
the last console = 300 meters):
The first console must be connected to the mixer amplifier as explained previously.
The 2nd console must be connected to the "COM 02" port of console n ° 1 (and on its side to its Input RJ45 "COM
01"). If it is the last console connected in BUS mode, switch 8 ‘’Terminal’’ must be ‘’ON’’ (down position).
Each console must then be configured via the zone switches (5) on the rear panel seen previously so that they
are recognized by the system.

To note: console 10 being in this example the last console in BUS, this is why switch 8 must be ‘’ON’’. Only one
console can have higher priority on the others. Switches are ‘’ON’’ when they are down.
Once connected, switch ‘’POWER’’ of zone (1) upwards on ‘’ON’’.
To adjust the console volume (potentiometer in zone (3) above), follow the instructions below:
1) Test the Console by selecting a zone (to which speakers are connected) using the zone buttons (3) on the
front panel below
2) Press the `` CALL '' button (4) on the front panel below to trigger the chime and be able to speak (this allows
you to adjust the volume of the microphone in parallel according to the sound level received in the speakers /
this level is adjustable via the potentiometer (3) on the rear panel)
To speak in one or more zones from the console, you must:
1) Select the desired zone(s) with zone buttons (3) or all zones
with the button (5)
2) The LEDs of the selected zones then blinks in green (if LEDs are
staying in green permanently , it means zone(s) are busy)
3) Press the "CALL" button, the chime will trigger and then you
can speak (the ring on the microphone head also lights up in red)
4) Press the "CALL" button again to stop the broadcast
To note: If you prefer to maintain ‘’CALL’’ button to speak and
release it to end speaking then you can activate ‘’PTT’’ = ‘’Push To
Talk’’ switch on console rear, zone (5).
A 3.5mm Jack "AUX IN" input is also available on the rear panel (4). It allows you to broadcast a pre-recorded
message, for example via an external audio device such as a Smartphone. The operation for broadcasting is the
same as the one seen previously for speaking in one or more zones.

You must :
1) Select the desired zone(s) with zone buttons (3) or all zones with button (5)
2) The LEDs of selected zones then blink in green
3) Press the "CALL" button, the chime will trigger. Then you can start your pre-recorded message
4) Press the "CALL" button again to stop the broadcast
LEDs in zone (2) on the front of the console indicate:
- Green LED "POWER" on = Console powered on
- Green LED "SEND" on = Console broadcasting
- Green LED "BUSY" on = Input "EMC" of the mixer amplifier or Input "MIC1" are broadcasting
