Connection Diagram

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

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.

System remote control wire (sold separately)

Connect the male terminal of this wire to the system remote control

terminal of the car stereo (SYSTEM REMOTE CONTROL). The

female terminal can be connected to the auto-antenna relay control

terminal. If the car stereo does not have a system remote control ter-

minal, connect the male terminal to the power terminal through the

ignition switch.

Setting the Unit

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” posi-

tion. 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.

Power Indicator

The power indicator lights when the

power is switched on.

RCA Input Select Switch

For two-channel input, slide this switch

to the left. For four-channel input, slide

this switch to the right.

Cut Off Frequency Control

Combining LPF/HPF/BPF and

LOW/HIGH select switch settings lets

you select between cut off frequencies

from 40 to 120 Hz and 3k to 9k Hz.

To prevent damage

• 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

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

rest or idle.

• 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

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

bridge connections, the speaker impedance must

be 2 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.

• Cords for this product and those for other prod-

ucts may be different colors even if they have the

same function. When connecting this product to

another product, refer to the supplied Installation

manuals of both products and connect cords that

have the same function.

LPF (Low-Pass Filter)/HPF (High-Pass Filter)/BPF (Band-Pass Filter) and

LOW/HIGH Select Switch

Set the LPF/HPF/BPF and LOW/HIGH select switch as follows according to the type of

speaker that is connected to the speaker output connector and the car stereo system:

LPF/HPF/BPF Audio frequency range Speaker Remarks

and LOW/HIGH to be output Type

Select Switch

LPF HIGH *

— 3k to 9k Hz Mid Connect a mid range speaker.

LOW *

— 40 to 120 Hz Subwoofer Connect a subwoofer.

HPF HIGH *

3k to 9k Hz — Tweeter*

Connect a tweeter.

LOW *

40 to 120 Hz — Full range Use if you want to cut the

very low frequency range*

because it is not necessary

for the speakers you are

using.

BPF (for CH A)*

40 to 120 Hz — Mid Connect a mid range speaker.

— 3k to 9k Hz

OFF Full range Full range

See the “Cut Off Frequency Control” section.

With CH A, even if the setting is HPF-HIGH, you can only select the same cut off frequency as with

HPF-LOW (40 to 120 Hz).

If you connect the tweeter directly, you must set the CH B to HPF-HIGH.

Be sure to set the LOW/HIGH select switch to HIGH.
