Precaution

• This unit is designed for negative ground 12 V

DCoperationonly.

• Usespeakers with suitable impedance.

-- HI-CURRENTmode: 1 to2_.

-- HI-VOLTAGEmode: 2 to 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.

• If your car is parked in direct sunlight and there

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 a fuse with an amperage rating

exceeding the one supplied with the unit as this

could damage the unit.

*Protection circuit

This amplifieris providedwith aprotection circuit that

operatesin thefollowing cases:

-- whenthe unit is overheated

-- whena DCcurrent is generated

-- whenthe speakerterminalsareshort circuited.

Thecolorofthe POWERIPROTECTOR indicatorwill

changefrom green to red,and the unit will shut down.

If this happens,turn off theconnected equipment, take out

thecassettetapeor disc,anddetermine thecauseof the

malfimction.If the amplifierhasoverheated,wait until the

unit coolsdown beforeuse.

If you have any questions or problems concerning

your unit that are not covered in this manual,

please consult your nearest Sony dealer.

* HI-CURRENT only

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 a built-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 a highly

ef_cient power supply with a low 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'hecoiol 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.
