Am5742 - LEGRAND 3440 Technical Sheet

Flush mounted stereo amplifier
Description
This device amplifies the stereo signal on the BUS and controls up to two loudspeakers
with impedance between 8-16 Ω. On the front the amplifier 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
configured the amplifier can have two modes:
- "FOLLOW ME" mode: function which allows the same music in another room after the
amplifier of the room previously occupied has been switched off and switching on the
amplifier on the room you are now in.
- "NO FOLLOW ME" mode: when another amplifier is switched on, on changing room,
the source configured the same as the configurator (inserted on M2) inserted on the
amplifier 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.

Configuration
A: 1-9
address of the amplifier room
PF: 0-9 amplifier address
M2: - (no configurator) when the amplifier is switched on, the last source which
was on is activated, "FOLLOW ME" mode
1-4 when the amplifier is switched on, the source with the same configuration
as that set on the device itself switches on (example amplifier with M2=2,
in this case the source with S=2 will switch on), "NO FOLLOW ME" mode.
