Description
This device amplies the stereo signal on the BUS and controls up to two loudspeakers
with impedance between 8-16 Ω. On the front the amplier has two pushbuttons which
can: switch the loudspeakers ON/OFF, adjust the volume in output, change the audio
source and cycle the saved stations (for the radio) or change the CD tracks. Correctly
congured the amplier can have two modes:
- “FOLLOW ME” mode: function which allows the same music in another room after the
amplier of the room previously occupied has been switched o and switching on the
amplier on the room you are now in.
- “NO FOLLOW ME” mode: when another amplier is switched on, on changing room,
the source congured the same as the congurator (inserted on M2) inserted on the
amplier switches ON, not necessarily the source which was being listened to before.
By using the “+” input of one channel and the “-” input of the other channel, it is possible
to install only one loudspeaker and create a monophonic system.

Conguration
A: 1-9 address of the amplier room
PF: 0-9 amplier address
M2: - (no congurator) when the amplier is switched on, the last source which
was on is activated, “FOLLOW ME” mode
1-4 when the amplier is switched on, the source with the same conguration
as that set on the device itself switches on (example amplier with M2=2,
in this case the source with S=2 will switch on), “NO FOLLOW ME” mode.
