The Safety of Your Ears is in

Your Hands

Get the most out of your equipment by playing

it at a safe level—a level that lets the sound

come through clearly without annoying blar-

ing or distortion and, most importantly, with-

out 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.

ESTABLISH A SAFE LEVEL:

! Set your volume control at a low setting.

! Slowly increase the sound until you can

hear it comfortably and clearly, without dis-

tortion.

! Once you have established a comfortable

sound level, set the dial and leave it there.

BE SURE TO OBSERVE THE FOLLOWING

GUIDELINES:

! Do not turn up the volume so high that you

can’t hear what’s around you.

! Use caution or temporarily discontinue use

in potentially hazardous situations.

! Do not use headphones while operating a

motorized vehicle; the use of headphones

may create a traffic hazard and is illegal in

many areas.

Before connecting/

installing the amplifier

WARNING

! The use of a special red battery and ground

wire RD-223, available separately, is recom-

mended. Connect the battery wire directly to

the car battery positive terminal + and the

ground wire to the car body.

! This unit is for vehicles with a 12 V battery and

negative grounding. Before installing in re-

creational vehicles, trucks or buses, check the

battery voltage.

! When installing this unit, make sure to con-

nect the ground wire first. Ensure that the

ground wire is properly connected to metal

parts of the car’s body. The ground wire of the

one of this unit must be connected to the car

separately with different screws. If the screw

for the ground wire loosens or falls out, it

could result in fire, generation of smoke or

malfunction.

! Always use a fuse of the rating prescribed.

The use of an improper fuse could result in

overheating and smoke, damage to the pro-

duct and injury, including burns.

! Check the connections of the power supply

and speakers if the fuse of the separately sold

battery wire or the amplifier fuse blows. Deter-

mine and resolve the cause, then replace the

fuse with and identical equivalent.

! Always install the amplifier on a flat surface.

Do not install the amplifier on a surface that

is not flat or on a surface with a protrusion.

Doing so could result in malfunction.

Before you start

Front side

Rear side

To adjust the switch, use a flathead screwdri-

ver if needed.

1 LPF (low-pass filter) switch

Switch the settings based on the connected

speaker.

! When the Subwoofer is connected:

Select ON. This eliminates high range

frequency and outputs low range fre-

quency.

! When the full range speaker is con-

nected:

Select OFF. OFF outputs the entire fre-

quency range.

2 FREQ (cut off frequency) control

Cut off frequency selectable from 40 Hz to

500 Hz if the LPF select switch is set to ON.

3 BASS BOOST (bass boost level control)

switch

You can select a bass boost level from 0 dB,

6 dB and 12 dB.

4 GAIN (gain) control

If the output remains low, even when the car

stereo volume is turned up, turn the con-

trols to a lower level. If distortion occurs

when the car stereo volume is turned up,

turn these controls to a higher level.

! For use with an RCA equipped car stereo

(standard output of 500 mV), set to the

NORMAL position. For use with an RCA

equipped Pioneer car stereo, with maxi-

mum output of 4 V or more, adjust level

to match that of the car stereo output.

! For use with an RCA equipped car stereo

with output of 4 V, set to the HIGH posi-

tion.

! If you hear too much noise when using

the speaker input terminals, turn the

gain control to higher level.

5 Power indicator

The power indicator lights up to indicate

power ON.

Setting the unit

5707000011330S <6>

Setting gain properly

! Protective function included to prevent

malfunction of the unit and/or speakers

due to excessive output, improper use or

improper connection.

! When outputting high volume sound etc.,

this function cuts off the output for a few

seconds as a normal function, but output

is restored when the volume of the head

unit is turned down.

! A cut in sound output may indicate impro-

per setting of the gain control. To ensure

continuous sound output with the head

unit at a high volume, set amplifier gain

control to a level appropriate for the preout

maximum output level of the head unit, so

that volume can remain unchanged and to

control excess output.

! Despite correct volume and gain settings,

the unit sound still cuts out periodically. In

such cases, please contact the nearest

authorized Pioneer Service Station.

Gain control of this unit

Preout level: 4 V

Preout level: 2 V

(Standard: 500 mV)

Above illustration shows NORMAL gain set-

ting.

Relationship between amplifier gain

and head unit output power

If amplifier gain is raised improperly, this will

simply increase distortion, with little increase

in power.

Signal waveform when outputting at

high volume using amplifier gain

control

If the signal waveform is distorted due to high

output, even if the amplifier gain is raised, the

output power will change only slightly.

! Never wire the speaker negative cable directly

to ground.

! Never band together multiple speaker’s nega-

tive cables.

! If the system remote control wire of the ampli-

fier is connected to the power terminal via the

ignition switch (12 VDC), the amplifier will re-

main on with the ignition whether the car

stereo is on or off, which may exhaust battery

if the engine is at rest or idling.

! Install and route the separately sold battery

wire as far as possible from the speaker wires.

Install and route the separately sold battery

wire, ground wire, speaker wires and the am-

plifier as far away as possible from the anten-

na, antenna cable and tuner.

About bridged mode

! Do not install or use this amplifier by wiring

speakers rated at 4 W (or lower) in parallel to

achieve a 2 W (or lower) bridged mode (Dia-

gram B).

Amplifier damage, smoke, and overheating

could result from improper bridging. The am-

plifier surface could also become hot to the

touch and minor burns could result.

To properly install or use a bridged mode and

achieve a 4 W load, wire two 8 W speakers in

parallel with Left + and Right * (Diagram A)

or use a single 4 W speaker.

In addition, refer to the speaker instruction

manual for information on the correct connec-

tion procedure.

! For any further enquiries, contact your local

authorized Pioneer dealer or customer

service.

About suitable

specification of speaker

Before installing the amplifier

WARNING

! To ensure proper installation, use the supplied

parts in the manner specified. If any parts

other than those supplied are used, they may

damage internal parts of the amplifier, or be-

come loose causing the amplifier to shut

down.

! Do not install in:

— Places where it could injure the driver or

passengers if the vehicle stops suddenly.

— Places where it may interfere with the dri-

ver, such as on the floor in front of the dri-

ver’s seat.

! Install tapping screws in such a way that the

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

portant to prevent wires from being cut by vi-

bration of the car, which can result in fire.

! Make sure that wires do not get caught in the

sliding mechanism of the seats or touch the

legs of a person in the vehicle as short-circuit

may result.

! When drilling to install the amplifier, always

confirm no parts are behind the panel and

protect all cables and important equipment

(e.g. fuel/brake lines, wiring) from damage.

CAUTION

! To ensure proper heat dissipation of the ampli-

fier, ensure the following during installation:

— Allow adequate space above the amplifier

for proper ventilation.

— Do not cover the amplifier with a floor mat

or carpet.

! Protection function may activate to protect the

amplifier against overheating due to installa-

tion in locations where sufficient heat cannot

be dissipated, continuous use under high-vo-

lume conditions, etc. In such cases, the am-

plifier reduces the power output or shuts

down until it has cooled to a certain desig-

nated temperature.

! Place all cables away from hot places, such

as near the heater outlet.

Connecting the units Installation

5707000011330S <13>

! The optimal installation location differs de-

pending on the car model. Secure the ampli-

fier at a sufficiently rigid location.

La protection de votre ouïe

est entre vos mains

Pour assurer le rendement optimal de votre

matériel et – plus important encore – la protec-

tion de votre ouïe, réglez le volume à un niveau

raisonnable. Pour ne pas altérer votre sens de

la perception, le son doit être clair mais ne

produire aucun vacarme et être exempt de

toute distorsion. Votre ouïe peut vous jouer

des tours. Avec le temps, votre système auditif

peut en effet s’adapter à des volumes supéri-

eurs, et ce qui vous semble un « niveau de

confort normal » pourrait au contraire être ex-

cessif et contribuer à endommager votre ouïe

de façon permanente. Le réglage de votre ma-

tériel à un volume sécuritaire AVANT que votre

ouïe s’adapte vous permettra de mieux vous

protéger.

CHOISISSEZ UN VOLUME SÉCURITAIRE :

! Réglez d’abord le volume à un niveau infé-

rieur.

! Montez progressivement le volume jusqu’à

un niveau d’écoute confortable ; le son doit

être clair et exempt de distorsions.

! Une fois que le son est à un niveau confor-

table, ne touchez plus au bouton du vo-

lume.

N’OUBLIEZ PAS DE RESPECTER LES

DIRECTIVES SUIVANTES :

! Lorsque vous montez le volume, assurez-

vous de pouvoir quand même entendre ce

qui se passe autour de vous.

! Faites très attention ou cessez temporaire-

ment l’utilisation dans les situations pou-

vant s’avérer dangereuses.

! N’utilisez pas des écouteurs ou un casque

d’écoute lorsque vous opérez un véhicule

motorisé ; une telle utilisation peut créer

des dangers sur la route et est illégale à de

nombreux endroits.

Avant de connecter/

d’installer l’amplificateur

ATTENTION

! L’utilisation d’un fil de terre RD-223 et d’un fil

de batterie rouge spécial, disponibles séparé-

ment, est recommandée. Connectez le fil de la

batterie directement sur la borne positive +

de la batterie du véhicule et le fil de terre sur

la carrosserie du véhicule.

! Cet appareil est utilisable sur des véhicules

équipés d’une batterie 12 V avec mise à la

masse du négatif. Vérifiez la tension de la bat-

terie avant l’installation dans des véhicules de

caravaning, des camions ou des bus.

! Lors de l’installation de cet appareil, veillez à

connecter d’abord le fil de masse. Assurez-

vous que le fil de masse est connecté correc-

tement aux parties métalliques de la carrosse-

rie du véhicule. Le fil de masse de cet appareil

doit être connecté indépendamment au véhi-

cule à l’aide de vis différentes. Si la vis du fil

de masse se desserre ou tombe, il peut en ré-

sulter un incendie, de la fumée ou un dysfonc-

tionnement.

! Utilisez toujours un fusible correspondant aux

caractéristiques spécifiées. L’utilisation d’un

fusible incorrect peut entraîner une sur-

chauffe et de la fumée, des dommages au ni-

veau du produit et des blessures, incluant des

brûlures.

! Vérifiez les connexions de l’alimentation et

des haut-parleurs en cas de rupture du fusible

du fil de batterie vendu séparément ou de

l’amplificateur. Déterminez la cause et résol-

vez le problème, puis remplacez le fusible par

un fusible identique.

! Installez toujours l’amplificateur sur une sur-

face plane. N’installez pas l’amplificateur sur

une surface qui n’est pas plane ou sur une

sur face présentant une saillie. Ceci pourrait

entraîner un dysfonctionnement.

! Lors de l’installation de l’amplificateur, ne lais-

sez pas des pièces telles que des vis supplé-

mentaires se coincer entre l’amplificateur et

l’automobile. Ceci pourrait entraîner un dys-

fonctionnement.

! Ne laissez pas cet appareil entrer en contact

avec des liquides. Cela pourrait provoquer une

électrocution. Tout contact avec des liquides

pourrait aussi provoquer des dommages, de

la fumée et une surchauffe de l’appareil.

Les surfaces de l’amplificateur et des haut-

parleurs connectés peuvent également chauf-

fer et entraîner des brûlures mineures.

! En cas d’événement anormal, l’alimentation

de l’amplificateur est coupée de manière à évi-

ter tout dysfonctionnement de l’équipement.

Dans ce cas, coupez l’alimentation du sys-

tème et vérifiez les connexions de l’alimenta-

tion et des haut-parleurs. Si vous n’êtes pas

en mesure de déterminer la cause, veuillez

contacter votre revendeur.

! Déconnectez toujours la borne négative * de

la batterie préalablement, de manière à éviter

tout risque de choc électrique ou de court-cir-

cuit lors de l’installation.

! N’essayez pas de démontez ou de modifiez

cet appareil. Ceci pourrait provoquer un in-

cendie, une électrocution ou tout autre dys-

fonctionnement.

PRÉCAUTION

! Maintenez le niveau d’écoute à une valeur

telle que vous puissiez entendre les sons pro-

venant de l’extérieur.

! L’utilisation prolongée du système stéréo du

véhicule lorsque le moteur est à l’arrêt ou au

ralenti peut épuiser la batterie.

! Ce produit est évalué sous des conditions cli-

matiques modérées et tropicales conformé-

ment à la norme CEI 60065 sur les Appareils

audio, vidéo et appareils électroniques analo-

gues - Exigences de sécurité.
