3 AUX IN button (with LED)
It turns on (LED is lit) / off the AUX INPUT to the internal amplifier (and PRE OUT).
If activated, the CD/USB – MP3 player / tuner signal will not be sent to the internal amplifier (the
INTERNAL button LED will turn off).
L
The AUX INPUT signal is always sent to the MUSIC ON HOLD output
(that is not affected by the AUX IN button).
4 INTERNAL button (with LED)
It turns on (LED is lit) / off the CD/USB - MP3 player / tuner to the internal amplifier (and PRE OUT).
If activated, the AUX INPUT signal will not be sent to the internal amplifier (the AUX IN button
LED will turn off).
L
The CD/USB MP3 player / tuner signal is always sent to the INTERNAL PROGRAM output
(that is not affected by the INTERNAL button).
L
It takes 10 seconds (after pressing either the AUX IN or INTERNAL button) to store on its
memory the last selection.
5 CD/USB – MP3 player and tuner (read the relevant manual section at page 36).
6 Internal amplifier MASTER volume control
Note: all audio outputs via RCA connectors (INTERNAL PROGRAM, MUSIC ON HOLD, PRE
OUT) are not affected by the MASTER volume control.
7 LEDs
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
L
0 dB = signal level that allows to get the amplifier maximum power.
L
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.
