CONTROLS AND FUNCTIONS
FREQUENCY
SWITCH
INDICATORS
LIGHTS
X-OVER
Crossover sec-
tion.
Tripping
adjustment for
selecting HI-
PASS / LO-
PASS
crossover
frequency.
Filters slope is
12 dB/Oct.
(crossover at -3
dB).
Frequencies
can be chosen
among: 50-60-
80-100-120 Hz.
HI-PASS
frequencies can
be obtained in
stereo from
OUT-HI out-
puts, while LO-
PASS
frequencies are
mixed in mono
and amplified
on the output
connectors
(SPEAKERS).
ON
Lit when the
amplifier is on.
PHASE
Configuration switch
for LO-PASS output.
It allows to invert the
signal phase on the
SPEAKERS terminals.
Position 0: LO-PASS
and HI-PASS phases
(OUT-HI outputs) are
aligned.
Position -ϕ: LO-PASS
phase is inverted (-180°)
in relation to HI-PASS
phase.
It is useful in situations
where, acoustically,
linearity is lacking in the
crossover zone of HI-
PASS/LO-PASS
frequencies.
GENERAL
INPUT
PRE IN
Left and Right
inputs of the am-
plifier.
They can be used
to amplify the
PRE output of a
signal source
(radio, CD-
DAT), an
electronic cross-
over output or an
output of any
kind of signal
processor at pre-
amplified level.
HI-PASS
OUTPUT
OUT HI
FRONT
REAR
Preamplified
HI-PASS
outputs. Cut-off
frequency is
determined by
the X-OVER
switch on 50-
60-80-100-120
Hz. They are for
a stereo
amplifier, for
the reproduction
of HI-PASS
FRONT fre-
quencies and
HI-PASS
REAR if
provided.
PHASE SWITCH
LEVEL CONTROLS
BOOST
Level adjustment for the band-pass filter in
the LO-PASS section.
It allows to highlight a limited frequencies
range centered at 45 Hz.
Adjustment range is between 0 and +6 dB.
It is useful when dealing with weak
SUBWOOFERS systems.
LO-PASS
Level control for
the amplifier LO-
PASS output.
Sensitivity varies
from a maximum
of 300 mV to a
minimum of 4 V.
SAFE
When lit, it indi-
cates the inter-
vention of pro-
tection circuits:
in case of over-
heating (tempe-
rature exceeding
80° C /176° F)
or output ano-
malies (presen-
ce of continuous
current, short
circuit, or
dangerously low
load impedan-
ce).
When protection
circuits
intervene, the
amplifier shuts
down.
Turn the ampli-
fier off.
When the pro-
blem is
corrected, turn
the amplifier
back on.
