Gain Control

Adjusting the gain controls A and B will help match the output of the car stereo to the Pioneer amplifier.

Normally, set the gain controls to the NORMAL position. If the output is low, even when the volume of the car stereo is turned up, turn these controls clockwise. If there is distortion when the volume of the car stereo is turned up, turn these controls counter-clock-

BFC (Beat Frequency

Control) Switch

If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.

CAUTION

•Disconnect the negative (–) terminal of the battery to avoid the risk of short-circuit and damage to the unit.

•Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around it where they lie against metal parts.

•Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body.

• Make sure that wires will not interfere with mov-

ing parts of the vehicle, such as the gearshift,

handbrake or seat sliding mechanism.

• Do not shorten any wires. Otherwise the protec-

tion circuit may fail to work when it should.

• Never feed power to other equipment by cutting

the insulation of the power supply wire to tap

from the wire. The current capacity of the wire

will be exceeded, causing overheating.

• Never replace the fuse with one of greater value

or rating than the original fuse. Use of an improp-

er fuse could result in overheating and smoke and

Connecting the Power Terminal

•Always use the special red battery and ground wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body.

1. Pass the battery wire from the

engine compartment to the interior

of the vehicle.

• After making all other connections to the

amplifier, connect the battery wire terminal of

the amplifier to the positive (+) terminal of

WARNING

Failure to securely fasten the battery wire to the ter- minal using the terminal screws could cause the ter- minal area to overheat and could result in damage and injury including minor burns.

Connecting the Speaker Output Terminals

• When using with an RCA equipped car

stereo (standard output of 500 mV), set

to the NORMAL position. When using

with an RCA equipped Pioneer car

adjust level to match the car stereo out-

put level.

CAUTION:

To prevent damage and/or injury

• Do not ground the speaker wire directly or con-

nect a negative (–) lead wire for several speakers.

• This unit is for vehicles with a 12-volt battery and

negative grounding. Before installing it in a recre-

ational vehicle, truck or bus, check the battery

voltage.

• Speakers to be connected to the amplifier should

conform with the standards listed below. If they

do not conform, they may catch fire, emit smoke

or become damaged. The speaker impedance must

be 2 Ω to 8 Ω. But in case of two-channel and

other bridge connections, the speaker impedance

Input Select Switch

For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right.

• If the car stereo is kept on for a long time while

the engine is at rest or idling, the battery may go

dead. Turn the car stereo off when the engine is at

rest or idling.

• If the system remote control wire of the amplifier

is connected to the power terminal through the

ignition switch (12 V DC), the amplifier will

always be on when the ignition is on— regardless

of whether the car stereo is on or off. Because of

this, the battery could go dead if the engine is at
