Manual del Propietario

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 autho- rized PIONEER Service Station.

CAUTION

Never replace the fuse with one of greater value or rating than the original fuse. Use of an improper fuse could result in over- heating and smoke and could cause dam- age to the product and injury including burns.

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

Terminal Cover

Before setting up the unit, unfasten the screws with a 4 mm hexagonal wrench (not supplied) and remove the terminal cover.

LPF (Low-Pass Filter)/HPF (High-Pass Filter) 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:

LPF/HPF Select	Audio frequency range	Speaker	Remarks
Switch	to be output	Type
LPF (Left)	* — 40 Hz to 120 Hz	Subwoofer	Connect a subwoofer.

OFF (Center)	Full range	Full range
HPF (Right)	* 40 Hz 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.

* See the “Cut Off Frequency Control” section.

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.

Cut Off Frequency Control

If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off frequency from 40 Hz to 120 Hz.

Power Indicator

The power indicator lights when the power is switched on.

For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right.

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.

• DO NOT allow amplifier to come into contact

with liquids due to, for example, the location

where the amplifier is installed. Electrical shock

could result. Also, amplifier and speaker damage,

smoke, and overheating could result from contact

with liquids. In addition, the amplifier surface and

the surface of any attached speakers could become

hot to the touch and minor burns could result.

Input Switch

It is possible to input from a car stereo external output (subwoofer output) or a car stereo speaker output. When using an external output (subwoofer output), slide the switch to the left. For connec- tion instructions, see the “Connection Diagram” section. When using a speak- er output, slide the switch to the right. In this case, it is necessary to use the supplied speaker input wire with RCA pin cord. For details, see the “Using the Speaker Input” section.

BFC (Beat Frequency Control) Switch

BFC switch is on the bottom of the unit. 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.

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 dis- tortion 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.
