Setting the Unit <ENGLISH>

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-clockwise.

•If you only use one input plug, set the gain controls for speaker outputs 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 Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level.

Connecting the Unit

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

• 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

Connection Diagram

•This diagram shows connections using external output (subwoofer output). Slide the input switch to the left.

•When you connect with speaker output, connections defers from the diagram. For details, see the “Using the Speaker Input” section. In either case, you need to set the input switch. For details, see the “Setting the Unit” section.

Fuse (30 A)

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

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.

• 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

could cause damage to the product and injury

including burns.

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.

• 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

• 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 to 8 ohms. But in case of two-channel and

other bridge connections, the speaker impedance

must be 4 to 8 ohms.

• Install and route the separately sold battery wire

as far away as possible from the speaker wires.

Install and route the separately sold battery wire,

ground wire, speaker wires and the amplifier as

far away as possible from the antenna, antenna

cable and tuner.

External Output

If only one input plug is used, do not connect anything to RCA input jack B.
