i
The AUX INPUT A signal is always sent to the MUSIC ON HOLD output (that is not affected
by the AUX A and AUX B buttons).
4
AUX B button (with LED)
It turns on (LED is lit) / off the AUX INPUT B to the internal amplifier (and PRE OUT).
If activated, the AUX INPUT A signal will not be sent to the internal amplifier (the AUX A button
LED will turn off).
It takes 10 seconds (after pressing either the AUX A or the AUX B button) to store on its memory
the last selection.
5
Internal amplifier MASTER volume control
Note: the audio outputs having RCA connectors (MUSIC ON HOLD and PRE OUT) are not
affected by the MASTER volume control.
6
LEDs
i
0 dB = signal level that allows to get the amplifier maximum power.
i
The internal 'limiter' circuit helps to avoid the amplifier overloading, yet it is advisable to
reduce the MASTER volume (or a single channel volume where a too high signal is present)
when the SIG/PK LED is continuously indicating red.
7
Main POWER switch (0 = off; I = on)
ON green: the device is switched on
PROT red: overload protection
orange: thermal protection
PRIOR yellow: priority by either the VOX function or an universal input
or the SEQ. COMMAND.
SIG/PK green: the signal level is higher than – 15 dB
green + red: the signal level is in the 0 ÷ +2 dB range
red: the signal level is equal or higher than +3 dB
