Before Using This Product

This product complies with the EMC Directives (89/336/EEC, 92/31/EEC) and CE Marking Directive (93/68/EEC).

Thank you for purchasing this PIONEER product. Before attempting operation, be sure to read this manual.

In case of trouble

When the unit does not operate properly, contact your dealer or the nearest authorized 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-circuitduring 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.

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” 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.

If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise.

Input Select Switch

For two-channelinput, slide this switch to the left. Forfour-channelinput, slide this switch to the right.

Power Indicator

The power indicator lights when the power is switched on.

ENGLISH

BFC (Beat Frequency Control) Switch

If you hear a beat while listening to an MW/LW broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.

LPF (Low-PassFilter)/HPF(High-PassFilter) Select Switch

Set the LPF/HPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system:

Connecting the Unit

CAUTION

Disconnect the negative (–)terminal of the battery to avoid the risk ofshort-circuitand 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-circuitthrough the vehicle body.

To prevent damage

Do not ground the speaker wire directly or connect a negative (–)lead wire for several speakers.

This unit is for vehicles with a 12-voltbattery and negative grounding. Before installing it in a recreational 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 idling.

Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism.

Do not shorten any wires. Otherwise the protection 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.

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-channeland 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.

Cords for this product and those for other products 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.
