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

Thisamplifierisprovidedwith aprotection circuit that operatesin thefollowing cases:

-- whentheunit is overheated

-- whena DCcurrent is generated

-- whenthe speakerterminalsareshort circuited.

Thecolorofthe POWERIPROTECTOR indicatorwill changefrom green to red,and theunit will shut down.

If this happens,turn off theconnected equipment, take out thecassettetapeor disc, and determine 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.

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 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

LEVEL LOWBOOST LPFOFF HPF

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.
