Gain Control

Adjusting the gain controls A and B will help match the out- put of the car stereo to the Pioneer amplifier. Normally, set the gain controls to the NORMAL position. If the out- put is low, even when the vol- ume of the car stereo is turned up, turn these controls clock- wise. If there is distortion when the volume of the car

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

stereo is turned up, turn these controls counter-clockwise.

• If you only use one input plug, set

the gain controls for speaker out-

puts A and B to the same position.

• When using with an RCA

equipped car stereo (standard

output of 500 mV), set to the

NORMAL position. When

using with an RCA equipped

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.

could cause damage to the product and injury

including burns.

• 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
