Setting the Unit

Gain Control

If the sound level is too low, even when

the volume of the car stereo used along

with this power amplifier is turned up,

turn gain control on the front of the

power amplifier clockwise. If the sound

distorts when the volume is turned up,

turn the gain control counter-clockwise.

• 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.

• If you hear too much noise when using the

speaker input terminals, turn the gain

control counter-clockwise.

Power Indicator

The power indicator lights when the

power is switched on.

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.

Thank you for purchasing this PIONEER

product. Before attempting operation, be

sure to read this manual.

Composition of Manual

This manual applies to the GM-X972,

GM-X572 and GM-X372. However, the

illustrations show the GM-X972.

In case of trouble

When the unit does not operate properly,

contact your dealer or the nearest autho-

rized PIONEER Service Station.

WARNING

• 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.

• Do not touch the amplifier with wet hands.

Otherwise you may get an electric shock. Also, do

not touch the amplifier when it is wet.

• For traffic safety and to maintain safe driving

conditions, keep the volume low enough so that

you can still hear normal traffic sound.

• Check the connections of the power supply and

speakers if the fuse of the separately sold battery

wire or the amplifier fuse blows. Detect the cause

and solve the problem, then replace the fuse with

another one of the same size and rating.

• To prevent malfunction of the amplifier and

speakers, the protective circuit will cut the power

supply to the amplifier (sound will stop) when an

abnormal condition occurs. In such a case, switch

the power to the system OFF and check the

connection of the power supply and speakers.

Detect the cause and solve the problem.

• Contact the dealer if you cannot detect the cause.

• To prevent an electric shock or short-circuit

during connection and installation, be sure to

disconnect the negative (–) terminal of the battery

beforehand.

• Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier. Be

sure to protect all cables and important equipment

such as fuel lines, brake lines and the electrical

wiring from damage.
