CONFIGURATION OF CONNECTING CLAMPS
POWER SUPPLY
CLAMPS
OUTPUT CLAMPS
REMOTE
IN
Turn on control for
the amplifier coming
from radio-cassette
player (or from any
sources provided
with remote control
for amplifiers).
The applied voltage
must be between 3
and 15 VDC.
OUT
Output leading to
other amplifiers of
the sound system.
It has to be connected
to the REMOTE IN
of successive
amplifiers to allow
the simultaneous
turning on of the
whole system.
The available volta-
ge on this output is
12 VDC with a cur-
rent equal to 250 mA.
IN
Input control coming from ra-
dio/cassette player (or any source
provided with output for the
amplifier mute). It is especially
made to be connected to the mute
output of a cellular telephone in
order to silence the amplifier for
incoming calls, and it allows to
reactivate musical reproduction
at the end of phone conversation.
It can be connected to the MUTE
OUT output of a preceeding am-
plifier to allow the simultaneous
silencing of all amplifiers
connected in cascade. The ap-
plied voltage must be between 3
and 15 VDC.
MUTE
OUT
Output for the other amplifiers
in the reproduction system. It
must be connected to the MUTE
IN of the successive amplifier to
allow the simultaneous silencing
of all amplifiers connected in
cascade. The available voltage
on this output is 12 VDC with
current equal to 5 mA.
L / R
Power outputs for
the Left and Right
channels of the
amplifier.
Connect the
loudspeakers ac-
cording to indica-
ted polarities.
MONO
Outputs for
bridged mono
configuration.
To be used when
the amplifier is se-
lected in MONO
IN R configuration
through the switch
on the front side
of the amplifier.
POWER
Input clamps
for the ampli-
fier power
supply.
Connect the
battery positi-
ve and negati-
ve according
to the indica-
ted polarities.
The applied
voltage must
be between
11 and 15
VDC.
