When the unit does not operate properly, contact your dealer or the nearest autho- rized PIONEER Service Station.

or use a single 4 Ω speaker per channel. If you have any questions or concerns, please contact your local authorized Pioneer dealer or call Pioneer customer service.

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.

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.

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.

4 Ohm Bridged Mode 2 Ohm Bridged Mode

Do NOT install or use your Pioneer ampli- fier by wiring speakers rated at 4 Ohm (or lower) in parallel to achieve a 2 Ohm (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result.

To properly install or use a bridged mode for a two-channel amplifier and achieve a 4

Ωload, wire two 8 Ω speakers in parallel

with Left + and Right - (Diagram A) or use a single 4 Ω speaker. For a four-channel amplifier, follow the speaker output con- nection diagram for bridging as shown on the back of your amplifier, and wire two 8

Ωspeakers in parallel to achieve a 4 Ω load

• 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.
