CONFIGURATION OF CONNECTING CLAMPS
REMOTE
IN
Turn on control for
the amplifier
coming from radio-
cassette player (or
from any sources
provided with re-
mote control for
amplifiers).
Applied voltage
must be between
7
and 15 VDC.
POWER
Input clamps for
the amplifier
power supply.
Connect the batte-
ry positive and ne-
gative according
to indicated pola-
rities.
Applied voltage
must be between
11 and 15 VDC.
CH A / CH B
LO-PASS power
outputs (Ch A and
Ch B).
Clamps are
connected in parallel
to allow the
connection of two or
more acoustic repro-
duction units, for
example a pair of
SUBWOOFERS.
Available power
signal is MONO and
is subjected to the ac-
tion of the internal
BOOST filter and to
the intervention of
LO-PASS filter.
LO-PASS filter cut-
off frequency can
be selected through
the X-OVER switch
on the front panel of
the amplifier.
