4.3 - Functions and additional information

PRIORITY connectors

Allow you to connect a dry contact switch.

When these two borns are connected, all the other

sources (AUX and CD inputs) will be dimmed. The

default parameter is -30dB.

MUSIC ON HOLD connectors

Allow you to connect an amplifier to your

telephone switchboard in order to send a musical

signal during the music on hold.

Your switchboard must feature this function. The

wiring must be operated by a qualified technician.

Wiring: the signal must be sent to pins C and H.

TELE PAGING connectors

The TEL IN 1-3 connectors allow you to connect a

public-adress system to your amplifier. Any

incoming signal will be a priority. The settings will

go back to normal after the announcement.

Wiring: The PA system must be connected to pins

1 and 3.

Pin 1 is the negative (-Ve) Pin 2 is the mass, Pin

3 is the positive (+Ve) while Pin 4 is used for the

Mute.

Any signal detected via Pin 4 is a priority signal.

4.4 - Output terminal

The output terminal is located at the rear and can be used to plug Banana connectors or bare wires. The

black socket is the com while the red sockets are the positive (the choice depends on the voltage).

Please only use loudspeakers whose transformers have a total power lower than the power of the amplifier.

If using a loudspeaker system between 4 and 16 Ohms, use the corresponding 4-16 Ohms output. In this

case, the total power of the speakers must be closed to the total power of the amplifier (+/-10%).

The impedance must not be lower than 4 Ohms or high than 16 Ohms in order to prevent any damage to

the amplifier.
