INPUTS
L / R
Left and Right
inputs of the
amplifier.
Signal to be
applied to the
input must be
both balanced
and
unbalanced.
When
connection is
unbalanced,
please use
normal PIN-
RCA. When
connection is
balanced,
please use
audison cable
PIN-ABS.

PEAK R
It shows that
maximum output
power has been
reached. The light is
on when, for any
reasons, distortion on
the Right power
outputs is higher than
1% THD.
SPEAKER R
Right power
outputs of the
amplifier. Connect
loudspeakers
according to
indicated
polarities.
MONO
Outputs for
bridge mono
configuratio.
To be used when
the amplifier is
selected in
MONO IN R
configuration
through the
switch put on the
upper part of the
device.
SPEAKER L
Left power
outputs of the
amplifier.
Connect
loudspeakers
according to
indicated
polarities.
INDICATORS
LIGHTS
ON
Lit when the
amplifier is on.
SAFE
When lit, it indicates
the intervention of
protection circuits: in
case of overheating
(temperature
exceeding 80° C /
176° F) or output
anomalies (presence
of continuous
current, short circuit,
or dangerously low
load impedance).
When protection
circuits intervene,
the amplifier shuts
down. Turn the
amplifier off. When
the problem is
corrected, turn the
amplifier back on.

A/B: Input levels.
C: Only with balanced
connection, it allows to
connect (ON) or disconnect
(OFF) the input ground.
With unbalanced
connection, the switch
must be put on ON.
D: On ON, it allows the
bridge mono connection,
by using IN R input.
On OFF, the amplifier
works as stereo.

CONNECTIONS AND FUNCTIONS
Rear Side
MUTE
IN
Mute control coming from radio-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
preceding amplifier to allow the simultaneous silencing
of all amplifiers connected in cascade.
Applied voltage must be between 3 and 15 VDC or
connect to GND.
OUT
Output for the other amplifiers in the sound 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.
POWER
Input clamps for the
amplifier power
supply.
Connect the battery
positive and negati-
ve according to
indicated polarities.
Applied voltage
mest be between 11
and 15 VDC.
POWER SUPPLY
CLAMPS
REMOTE
IN
Turn on control for the
amplifier, coming from
radio-cassette player (or
from any sources
provided with remote
control for amplifiers).
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 the successive
amplifier to allow the simultaneous
turning on of the whole system. The
available voltage on this output is 12
VDC with a current equal to 250 mA.
