PIONEER SUGGESTS USING A PRO-

FESSIONAL INSTALLER DUE TO THE

COMPLEXITY OF THIS PRODUCT.

Please read all instructions and WARN-

INGS in this manual before attempting

operation. Should you have any questions,

contact your nearest Pioneer authorized

dealer or installation specialist.

Important

The serial number of this amplifier is writ-

ten on the bottom of the unit. For your

own security and convenience, write it

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.

Selecting fine audio equipment such as the unit you've just purchased is only the start of your

musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your

equipment offers. This manufacturer and the Electronic Industries Association's Consumer

Electronics Group want you to get the most out of your equipment by playing it at a safe level.

One that lets the sound come through loud and clear without annoying blaring or distortion--and,

most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of

sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard against

this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

· Start your volume control at a low setting.

· Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

· Set the dial and leave it there.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all,

we want you listening for a lifetime.

We Want You Listening For A Lifetime

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since

hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the

Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged

exposure to excessive noise. This list of sound levels is included for your protection.

Mode d'emploi

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 for stereo connection, and 2 to 8

ohms for monaural and other bridge connection.

· 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.

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.

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.

Connecting the Speaker wires

The speaker output mode can be two-chan-

nel (stereo), one-channel (mono), or three-

channel (stereo + mono). Connect the

speaker leads to suit the mode according to

the figures shown below.

· When either the RCA input or the speaker

input is connected, RCA output becomes

functional. Do not connect both the RCA

input and the speaker input at the same time.

Two-channel mode (stereo)

One-channel mode (mono)

Three-channel mode (stereo + mono)

The power amplifier is basically a two-

channel/one-channel bridgeable amplifier,

but three channels can be achieved by

combining the stereo and mono modes

using inductors and capacitors.

Three-channel mode, two-way system

Three-channel mode, three-way system

· Inductors (L1 and L2 in the diagrams)

act as low-pass filters. Capacitors (C1

and C2 in the diagrams) act as high-pass

filters. Inductors (L) are used for the

woofer/subwoofer, and capacitors (C)

are used for the high/mid-high.

· Remember when bridging an amplifier it

will see only half of the original speaker

impedance. Therefore, you must use

speakers that have ratings of 4 ohms or

higher. If you use speakers that have

lower impedance ratings it may cause

damage to the amplifier.

· When the inductors and capacitors are

connected to the speaker wires, secure or

solder them so they cannot be pulled

loose. Tape or use heat shrink on the

joints to prevent short circuits.

Setting the Filter Constant

Low-pass filter (for subwoofer/woofer):

6 dB/octave

High-pass filter (for mid/mid-high):

6 dB/octave

Band-pass filter (combination of low-pass

filter and high-pass filter for mid-

bass/mid): 6 dB/octave

· A multi-channel system can be set up using a

combination of filters. The inductance (L) and

capacitance (C) will determine the frequency (fc)

that the speaker will reproduce. Refer to the chart

below to determine the components required.

· Use the capacitors specified. Non-polarized capac-

itors rated at over ±25 V should be used for C1

and C2 in the diagram. Because of the voltage

output of the amplifier, it is very important to use

non-polarized capacitors rated at or over 25 V.

This will prevent a safety hazard.

Note:

· Specifications and the design are subject to possible modification without notice

due to improvements.

*Average current drawn

· The average current drawn is nearly the maximum current drawn by this unit

when an audio signal is input. Use this value when working out total current

drawn by multiple power amplifiers.

CAUTION

· Do not install in:

--Places where it could injure the driver or pas-

sengers if the vehicle stops suddenly.

--Places where it may interfere with the driver,

such as on the floor in front of the driver's

seat.

· Make sure that wires are not caught in the sliding

mechanism of the seats, resulting in a short-cir-

cuit.

· Confirm that no parts are behind the panel when

drilling a hole for installation of the amplifier.

Protect all cables and important equipment such

as fuel lines, brake lines and electrical wiring

from damage.

· Install tapping screws in such a way that the

screw tip does not touch any wire. This is impor-

tant to prevent wires from being cut by vibration

of the car, which can result in fire.

· To prevent electric shock, do not install the ampli-

fier in places where it might come in contact with

liquids.

· To ensure proper installation, use the supplied

parts in the manner specified. If any parts other

than the supplied ones are used, they may damage

internal parts of the amplifier, or they may

become loose causing the amplifier to shut down.

To prevent malfunction

· To ensure proper heat dissipation of the amplifier,

be sure of the following during installation.

--Allow adequate space above the amplifier for

proper ventilation.

--Do not cover the amplifier with a floor mat or

carpet.

· Do not install the amplifier near a door where it

may get wet.

· Do not install the amplifier on unstable places

such as the spare tire board.

· The best location for installation differs with the

car model and installation location. Secure the

amplifier at a sufficiently rigid location.

· Make temporary connections first and check that

the amplifier and the system operate properly.

· After installing the amplifier, confirm that the

spare tire, jack and tools can be easily removed.

Example of installation on the floor

mat or on the chassis

1. Place the amplifier where it is to be

installed. Insert the supplied tapping

screws (4

× 18 mm) into the screw

holes. Push on the screws with a

screwdriver so they make marks

where the installation holes are to be

located.

2. Drill 2.5 mm diameter holes at the

point marked, and install the ampli-

fier, either on the carpet or directly

to the chassis.

Cher Client:

La sélection d'un équipement audio de qualité comme l'unité que vous venez d'acheter n'est

que le début de votre plaisir musical. Maintenant, il est temps de penser à la manière de profiter au

maximum des plaisirs que vous offre votre équipement. Ce fabricant et le Groupe "Consumer

Electronics Group" de l'Association des Industries Electroniques veut que vous profitiez au maxi-

mum de votre équipement en l'utilisation à un niveau sûr. Un niveau qui permet au son d'être fort

et clair, sans beuglement ennuyant ou distorsion -- et, ce qui est plus important, sans affecter votre

ouïe sensible.

Le son peut être décevant. Avec le temps, le "niveau de confort" de votre ouïe s'adapte aux

volumes sonores plus élevés. Ainsi, les sons "normaux" peuvent en fait être forts et affecter votre

ouïe. Protégez-vous contre cela en réglant votre équipement à un niveau sûr AVANT l'adaptation

de votre ouïe.

Pour établir un niveau sûr:

Démarrer votre commande de volume à un réglage bas.

Augmentez lentement le son jusqu'à ce que vous l'entendiez confortablement et clairement,

sans distorsion.

Lorsque vous avez établi un niveau sonore confortable:

Réglez le cadran et laissez-le tel quel.

En prenant une minute pour faire cela, vous pourrez éviter des dommages ou des pertes de sen-

sibilités d'écoute dans le futur. Après tout, nous voulons que vous écoutiez pendant toute votre vie.

Nous voulons que vous écoutiez pendant toute votre vie

Utilisé avec sagesse, votre nouvel équipement sonore sera une source de plaisir pendant toute

votre vie. Comme les dommages de l'ouïe provenant d'un bruit fort ne sont souvent détectables

que lorsqu'il est trop tard, ce fabricant et le Groupe "Consumer Electronics Group" de

l'Association des Industries Electroniques vous recommandent d'éviter toute exposition prolongée

à un bruit excessif. Cette liste de niveaux sonores est incluse pour votre protection.

Nous vous remercions d'avoir porté votre

choix sur un appareil PIONEER. Il a été

conçu et fabriqué pour vous apporter de

nombreuses années de satisfaction.

En raison des problèmes posés par

l'installation de cet appareil, Pioneer vous

conseille de consulter un professionnel.

Avant d'utiliser l'appareil, prenez

connaissance de ce mode d'emploi et tout

spécialement des AVERTISSEMENTS.

Pour toute question concernant cet

appareil, veuillez vous adresser au

revendeur ou à l'installateur.

AVERTISSEMENT

· Utilisez le faisceau de câbles de liaison à la

batterie (un câble rouge et un câble de masse) qui

est vendu séparément [RD-223]. Reliez le câble

rouge à la borne positive (+) de la batterie et le

câble de masse à la carrosserie du véhicule.

· Ne touchez pas l'amplificateur quand vous avez

les mains mouillées, faute de quoi vous risquez de

ressentir une secousse électrique. Pareillement, ne

touchez pas l'amplificateur s'il est mouillé.

· Pour votre sécurité et celles des autres usagers de

la route, maintenez le niveau d'écoute à une

valeur telle que les bruits de la circulation

demeurent nettement perceptibles.

· Si le fusible monté sur le câble de liaison à la

batterie, câble qui est vendu séparément, a grillé

ou bien s'il en est ainsi de celui de l'amplificateur,

vérifiez soigneusement toutes les connexions

d'alimentation. Recherchez la cause de l'anomalie

puis corrigez-la; enfin, remplacez le fusible grillé

par un fusible de même taille et de même calibre.

· Pour éviter d'endommager l'amplificateur et les

haut-parleurs, le circuit de protection coupe

l'alimentation de l'amplificateur (les sons ne sont

plus émis) dès que survient une situation

anormale. Dans ce cas, mettez l'ensemble des

appareils hors tension et contrôlez les liaisons

entre l'amplificateur et les haut-parleurs. Le cas

échéant, recherchez la cause de l'anomalie et

corrigez-la.

· Consultez le revendeur si vous n'êtes pas en

mesure de résoudre le problème qui se pose à

vous.

· Pour éviter toute secousse électrique et tout risque

de court-circuit au cours des opérations de

raccordement et d'installation, n'oubliez pas de

débrancher le câble relié au pôle négatif de la

batterie () avant d'effectuer quelque opération

que ce soit.

· Avant d'effectuer un perçage requis par

l'installation de l'amplificateur, assurez-vous que

vous pouvez le faire sans danger pour les câbles,

canalisations, flexibles, etc., qui sont placés

derrière le panneau que vous devez percer.
