Max. voltage: 24 V; max. current: 0.5 A
A Amplifier output (max. 160 W) to loudspeakers
(100 / 70 V constant voltage line – 4 Ω impedance).
Use ONE output only (read the section ‘Loudspeaker connection’).
S Mains connector with fuse
Before connecting the power supply cable, verify that the apparatus voltage (230 or 115 V ac)
corresponds to the available mains supply.
Note: the fuse type is marked on the rear panel (below the mains connector).
OPERATION
L
‘VOX’ is an internal circuit that automatically activates the channel 1 priority when a signal is
detected on the audio INPUT 1.
POWER ON (OR WHEN A PRIORITY COMMAND ENDS)
If no priority command is present (including VOX and CHIME SEQUENTIAL COMMAND), all the
channels 1, 2, 3, 4 and the music source are mixed together.
The music source can be:
The internal CD/USB – MP3 player and tuner.
The AUX INPUT signal.
Disabled.
L
The music volume depends on either the CD/USB – MP3 player / tuner VOL control (if selected)
or the AUX IN volume control on the front panel (see 2). AUX INPUT level also depends on the
relevant GAIN control setting (see 16) on the rear panel.
L
The music source (internal or external) can be activated / muted through the front panel
buttons (see 3 and 4).
