Precaution
•This unit is designed for negative ground 12 V
DCoperationonly.
• Use speakers with suitable impedance.
-- HI-CURRENTmode:1to2_.
-- HI-VOLTAGEmode:2to 4f_.
• Do not connect any active speakers (with built-in
amplifiers) to the speaker terminals of the unit.
Doingso may damagethe active speakers.
• Avoid installing the unit where:
-- it would be subject to high temperatures such
from direct sunlight or hot air from the
heater
-- it would be exposed to rain or moisture
-- it would be subject to dust or dirt.

Fuse Replacement
If the fuse blows, check the power comaection 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 dealer.
Warning
When replacing thefuse, be sureto useone
matching the amperage stated above the fuse
holder. Never use afuse with an amperage rating
exceeding the one supplied with the unit as this
could damage the unit.
*Protection circuit
Thisamplifieris provided with a protection circuit that
operatesin thefollowing cases:
-- whenthe unit is overheated
-- whena DC current isgenerated
-- whenthe speaker terminalsareshort circuited.
Thecolorofthe POWERIPROTECTOR indicator will
changefrom green to red,and theunit willshut down.
If this happens,turn off theconnected equipment, take out
thecassettetape or disc,and determine thecauseof the

Features
•Maximum power output of 230 watts per
channel (at 4£_).
•This unit can be used as a bridging amplifier
with a maximum output of 580 watts.
•Direct connection can be made with the speake_
output of your car audio if it is not equipped
with the line output (High level input
connection).
• Built in variable LPF (Low-pass filter), HPF
(High-pass filter) and low boost circuit.
• Dual mode connection possible for a multi-
speaker system.
•Possible to switch between HI-CURRENT mode
(1-2 _) and HI-VOLTAGE mode (2-4 £2).
•Protection circuit and indicator provided.
•Pulse power supply* for stable, regulated output
power.
• New circuit wilich _emoves the _ouit:_ zesistance
from the final MOS FET output stage, and drives
the speaker directly.
* Pulse power supply
This unit has abuilt-in power regulator which converts
the power supplied by the DC 12 V ear battery into high
speed pulses using a semiconductor switch. These pulses
are stepped up by the built-in pulse transformer and
separated into both positive and negative power supplies
before being converted into direct current again. This is to
regulate fluctuating voltage from the car battery. This
light weight pawer supply system provides ahighly
ef_cient power supply with alow impedance output.

Location and Function of Controls
[] MODE indicator
IndicatesHI-CURRENT mode or HI-VOLTAGE mode.
[] POWER/PROTECTOR indicator
•OVER CURRENT lights up in green during normal operation, rl'he coiol will
change from green to amber when receiving a powerful signal.
• OFF SET lights up green during normal operation. The color will change
from green to amber when the voltage going out to the Speaker terminal or
the Pin Jack is too high.
• THERMAL lights up in green during normal operation. The color will
change from green to amber when the temperature rises to an unsafe level.
The color will return to green when the temperature returns to normal.
[] LEVEL adjustment control
The input level can be adjusted with this control when using source
equipment made by other manufacturers. Turn it to MAX when the output
level of the car audio seems low.
[] LOWBOOST level control
Turn this control to boost the frequencies around 40 Hz to a maximum of 10
dB.
[] Cut-off frequency adjustment control
Sets the cut-off frequency (50-200 Hz) for the low-pass or high-pass filters.
[] FILTER selector switch
When the switch is in the LPF position, the filter is set to low-pass. When in
the HPF position, the filter is set to high-pass.
[] HI-CURRENT/HI-VOLTAGE mode switch (located on the bottom of the unit)
Remove the bottom cover to access the switch.
•In HI-CURRENT mode the speaker impedance is 1 to 2 _. This
mode sends a signal via parallel circuits for a powerful sound
•In HI-VOLTAGE mode the speaker impedance is 2 to 4 ft. In this mode
you can enjoy clear sound with the dynamic range.

Caution
•Before making any connections, discolu_ect
the ground terminal of the car battery to avoid
short circuits.
* Be sure to use speakers with an adequate
power rating. If you use small capacity
speakers, they may be damaged.
• Do not connect the 0 terminal of the speaker
system to the car chassis, and do not connect
the 0 terminal of the right speaker with that
of the left speaker.
•Install the input and output cords away from
the power supply lead as running them close
together can generate some interference noise.
IThis unit is a high powered amplifer.
Therefore, it may not perform to its full
potential if used with the speaker cords
supplied with the car.
•If your car is equipped with a computer
system for navigation or some other purpose,
do not to remove the ground wire from the
car battery. If you disconnect the wire, the
computer memory may be erased. To avoid
short circuits when making connections,
disconnect the +12 V power supply lead until
all the other leads have been connected.
Make the terminal
connections as Illustrated below.
Note
When you tighten the screw, be careful not to
apply too much torque* as doing so may damage
the screw.
*The torque value should be less than 1N•m.
Pass the leads
through the cap,
connect the leads,
then cover the
terminals with the
cap.

Notes on the power supply
•Connect the +12 V power supply lead only after all the
other leads have been connected.
•Be sure to connect the ground lead of the unit
securely to a metal polnt of the car. A loose
connection may cause a malfunction of the
amplifier.
•Be sure to connect the remote control lead of the car audio
to the remote terminal.
•When using a car audio without a remote output on the
amplifier, connect the remote input terminal (REMOTE)
to the accessory power supply.
•Use the power supply lead with afuse attached (30 A).
•Place the fuse in the power supply lead as close as possible
to the car battery.
•Make sure that the leads to be connected to the +12 Vand
GND terminals of this unit respectively must be larger
than lO-Gauge (AWG- IO) or "with the sectional area of
mare than 5mmL
•When using the optional RC-46 power amplifier
connecting cord, consult that manual for proper use.

Notes
•When using passive crossover networks in a multi-speaker
system, care must be taken as the speaker system's
;impedance should not be lower than that of the suitable
;impedancefor this unit.
•When you are installing a 12 decibels/octave system in
your car, the following points must be considered. In a 12
decibels/octave system where both a choke and capacitor
are used in series to form a circuit, agreat care must be
taken when they are connected. In such a circuit, there is
going to be an increase in the current which by-passes the
speaker with frequencies at around the crossover
frequency. If audio signals are continued to befed into the
crossover frequency area, it may cause the amplifier to
become abnormally hot or the fuse will be blown. Also if
the speaker is disconnected, a series-resonant circuit will
be formed by the choke and the capacitor. In this case, the
impedance in the resonance area will decrease
dramatically resulting in a short circuit like situation
causing a damage to the ampli_er. Therefore, make sure
that aspeaker is connected to such a circuit at all times.
