Description
This amplier, tted with hooking device for installation on DIN rail, is particularly suited
for non residential applications, or in more general terms, where there are no space
constraints inside distribution boards/switchboards. Directly powered by the power line
voltage, the low level of current consumption on the BUS makes multiple installations
possible (max. 40 ampliers and 80 loudspeakers). Depending on its conguration, a
stereo or a mono signal can be set on the output towards the loudspeakers. Loudspeakers
with both 8 Ω and 16 Ω impedance may be connected to the amplier. The device may be
controlled using either its own keys, the TOUCH SCREEN, or special controls.

Dissipated power: 2 W
Operating temperature: 5 - 45 °C
Power (on 8 Ω): 2 Wrms (1 Wrms+1 Wrms)
16 Wpmpo (8 Wpmpo+8 Wpmpo)
TYP channel balancing: ± 0.5 dB
MIN channel balancing: ± 1.5 dB
Frequency range @ -3 dB: 20 Hz–20 kHz (su 8 Ω)
Legend
1. clamp for connection of the power supply
2. clamps for loudspeaker connection
3. configurator socket
4. removable clamp for BUS connection
5. the LED under “ON/OFF” indicates the amplifier state: if it is off there is no BUS, if it is
green the device is in Stand-By, if it is orange the amplifier is on. The LED under “PO-
WER” indicates: when off, no power line voltage is detected, if it is RED the amplifier
is powered.
6. pushbuttons for local switching on or off of the amplifier (simple touch), and for
volume adjustment (prolonged pressure).
Conguration
A: 1-9 address of the amplier room
PF: 0-9 amplier address
M1*: - (no congurator) volume level equal to 20% and “MUTE” mode:
in this mode, when the video door entry system is being used the volume
of the sound sources will be decreased
1 volume level equal to 20% but “MUTE” mode not available”
2 volume level equal to 50% and “MUTE” mode: in this mode, when the
video door entry system is being used the volume of the sound sources will
be decreased
3 volume level equal to 50% but “MUTE” mode not available
4 volume level equal to 100% and “MUTE” mode: in this, mode, when the
video door entry system is being used the volume of the sound sources
will be decreased
5 volume level equal to 100% but “MUTE” mode not available
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.
M3 - (no congurator) working correctly
1 both the outputs reproduce the signal received on the LEFT channel
2 both the outputs reproduce the signal received on the RIGHT channel
3 the amplier reproduces a monophonic signal on both the loudspeaker
outputs
* this mode can only be activated when the Sound System is integrated with the 2-wire
audio and video door entry system. This combination allows the “pager” function and
the volume level is set via the congurators.
