* The built-in 2/3 way switchable crossover
network enables you to enjoy the multi-way
speaker system with easy installation.
© Powerful output of 90 W x4+150 Wx 2 max.
(90 W'x4 +350 W max. with 5 channel
connection).
* Low boost (40 Hz) for heavy and powerful
bass sound which is usually insufficient in a
car audio sysiem.
* Built-in Bessel function filters* for creating a
smooth sound fink between bass and treble.
© Pulse power supply** for stable and
regulated output power.
SECTION 1
GENERAL
*Bessei function type fitters
Most of the currently available crossover networks
use the flat response fitters {Butterworth type). The
group delay characteristics of these filters are
considerably inferior to those of the linear phase
filters (Bessel function type) used in this unit. While
the conventional flat response filters are
susceptible to transit distortion in the audio signais
ai each filter's crossover irequency, the Bessei type
filters in this unit will raduce the distortion and
contribute in obtaining the optimum hi-fi sound.
**Pulse power supply
This unit has a built-in convertor which converts
the power supply from the DC 12 V car battery
into high speed pulse signais by the use of the
semiconductor switch. These signais will be
stepped up by the buiit-in pulse transformer and
separated into both positive and negative power
supplies before converted into the direct current
again. This is to regulate the othewise variable
voltage of the car battery. This light weight power
supply system provides the highly efficient power
supply with low impedance output.
Precautions
This section is extracted from
instruction manual.
* This unit is designed for negative ground 12
V DC operation only.
¢ The nameplate indicating the operating
voltage, etc. is located on the botiom exterior
of the unit.
« Use speakers with impedance of 2 to 8
ohms.
¢ Avoid installing the unit where it would be
subjected to:
—high temperatures caused by direct
sunlight or hot air from the heater.
—rain or moisture.
—dust or dirt.
° When installing the unit vertically, make sure
that the fins of the heat sink are vertical to
the floor.
x Not this way O This way
@ When installing the unit horizontally, make
sure that the fins are not covered by the
floor carpet etc..
° If the unit is installed too close to a car
tadio, it may cause interference in radio
reception. In such a case, place the unit
away from the radio.
© If your car is parked in direct sunlight and
there is a considerable rise in temperature
inside the car, allow the unit to cool off
before operating.
© This unit has a built-in protection circuit* to
protect the transistors and speakers if the
amplifier malfunctions. However do not
attempt to test this protection circuit by
covering the heat sink or overloading the
connections.
° For the road safety reasons, keep the volume
of the head unit moderate so that you will be
able to hear the sound outside your car.
If you have any questions or problems
concerning this unit that are not covered in
this manual, please consult your nearest Sony
dealer.
*Protection circuit
This unit has a built-in protection circuit which
operates in the following cases when:
~—the unit is overheated.
—a DC current is generated.
—the speaker terminals are short circuited.
When the protection circuit is activated, the red
indicator will light up and there will be an
abrupt loss of the sound from the speakers. If
this happens, turn off the connected
equipment and take out the cassette tape or
CD from deck and determine the cause of the
maltunction. If the unit becomes overheated,
wait until it cools down.

Fuse Replacement |
{f the fuse blows, check the power connection
and replace the fuse. If the fuse blows again
after replacement, there may be an internal
malfunction. in such a case, consult your
nearest Sony deater.
Warning
Use the specified fuse with correct amperage.
Use of a fuse with higher amperage may
cause serious damage to the unit.
