132:
Two-channel
amplifiers
with
compact
dimensions
and
excellent musical performances. The
outstanding
features
of
their
sophisticated
circuitry
are:
"FRONT
END"
stages
realized
by
two
complementary
differential
stages,
final
stages
made
of
transistors
in
Darlington
connection,
final
transistors
with
current
capacity
of
15
A and MOSFET PWM power supply with a high energy reserve. Their
design
allows
their
easy
functioning
on
2
Ohms
nominal
loads
in
stereo
configuration and 4 Ohms nominal loads in bridge mono configuration. These
features
allow
a
great
use
versatility
both
in
driving
multiway
systems
and
in SUBWOOFER mono connection in TRI-MODE configuration.
PRECAUTIONS ·
In
order
for
this
device
to
function
properly
it's
important
that
it
is
installed
in
a
spot
where
temperature
doesn't
fall
below
0
°
C
(
3
2
°
F)
or
rise
above
55
°
C
(131
°
F).
·
It must be installed in a dry and well ventilated spot.
·
Power
supply
voltage
is
12
VCC
with
negative
to
ground.
Make
sure
that
the
characteristics of the vehicle electrical system are compatible with this device.
·
For
safe
driving
we
advise
to
listen
to
music
at
a
volume
level
that
won't
drown
external traffic sounds.
INSTALLATION
For
mounting
use
4
self-threading
screws
and
protective
plastic
rings
provided.
For
a
very
good
result
we
suggest
to
use
audison cable
products
to
complete
your
installation.
These
include:
power
cables,
signal
cables,
speaker
wires,
RCA
connectors and all accessories needed to complete the wiring.
WARNINGS ·
INPUTS:
If
the
radio-cassette
player
doesn't
share
the
output
GND
with
the
chassis,
the
braided
shield
of
the
shielded
cable
must
be
connected
to
the
radio-
cassette player chassis.
·
OUTPUTS:
Never
connect
-R
and
-L
outputs
to
ground
or
to
each
other.
If
a
crossover filter is used, be sure its two channels don't have a common ground.
·
REGULATIONS:
If
you
hear
saturation
phenomena
at
moderate
volume
levels,
it means that a distorted signal is coming from the radio-cassette player. Turn radio-cassette player volume down until there's no longer any distortion. Then
adjust
the
amplifier
calibration
levels
until
you
hear
slight
saturation
phenomena.
