AUX INPUT (A and B) TREBLE and BASS controls.

r
AUX INPUT A GAIN control.
t
AUX INPUT B with dual RCA connector.
y
AUX INPUT B GAIN control.

PRE OUT audio output (with RCA connector) that sends the same signal routed to the internal
amplifier (signal that can be either a single source with priority or the mix of all the channels 1,
2 and the selected AUX INPUT)..
Use PRE OUT to connect additional external amplifiers.
i
MUSIC ON HOLD audio output (with RCA connector) that sends a mono signal of the source
connected to the AUX INPUT A.
The MUSIC ON HOLD output is not affected by any volume control nor selector and (if an external
music source has been connected to the AUX INPUT A) can be used for the connection to a
telephone system (in order to have the 'music on hold' function).
