About This Product

This product is a class D amplifier for the

subwoofer. If both L (left) and R (right)

channels are connected to the RCA input

of this product, output is mixed because

this product is a mono amplifier.

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.

WARNING

· Handling the cord on this product or cords associ-

ated with accessories sold with the product will

expose you to lead, a chemical known to the State

of California and other governmental entities to

cause cancer and birth defects or other reproduc-

tive harm. Wash hands after handling.

· Always use the recommended battery wire and

ground wire, which is sold separately. Connect the

battery wire directly to the car battery positive ter-

minal (+) 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

subwoofer if a fuse for the separately sold battery

wire blows. Detect the cause and solve the prob-

lem, then replace the fuse with another one of the

same size and rating.

· To prevent malfunction of the amplifier and sub-

woofer, 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 subwoofer.

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.

· 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.

CAUTION:

To prevent damage and/or injury

· 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 idling.

· DO NOT connect a subwoofer with a lower

impedance than specified in the "Connecting the

Unit" section. Amplifier damage, smoke, and

overheating could result from a non-specified con-

nection. The amplifier surface could also become

hot to the touch and minor burns could result.

· Connect either of two subwoofers to the amplifier;

1: a subwoofer with a 500 W or larger nominal

input and an impedance 4

, or 2: a subwoofer

with a 1,000 W or larger nominal input and an

impedance 2

. If the nominal input and imped-

ance are out of the above ranges, the subwoofer

may catch fire, emit smoke or become damaged.

· 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.

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.

· 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.

· Never replace the fuse with one of greater value

or rating than the original fuse. Use of an improp-

er fuse could result in overheating and smoke and

could cause damage to the product and injury

including burns.

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 important

to prevent wires from being cut by vibration of the

car, which can result in fire.

· 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.

· 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.

· Never replace the fuse with one of greater value

or rating than the original fuse. Use of an improp-

er fuse could result in overheating and smoke and

could cause damage to the product and injury

including burns.

CAUTION:

To prevent malfunction and/or injury

· 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 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.

· 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

ATTENTION

· Utilisez le câble de liaison à la batterie et le câble

de masse conseillés; ils sont vendus séparément.

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.

· Vérifiez les raccordements de l'alimentation et du

haut-parleur d'extrêmes graves si le fusible du

câble de liaison (vendu séparément) à la batterie

vient à griller. 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 du

haut-parleur d'extrême grave, 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 du haut-parleur

d'extrême grave. 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.

· NE LAISSEZ PAS l'amplificateur entrer en

contact avec des liquides à cause, par exemple, de

l'emplacement où il a été placé. Cela pourrait

entraîner une secousse électrique. De plus, le

contact avec un liquide pourrait endommager

l'amplificateur et les enceintes, produire de la

fumée ou surchauffer l'appareil. Enfin, la surface

de l'amplificateur et des enceintes connectées peut

devenir chaude au toucher et entraîner de légères

brûlures.

Réglage de l'appareil

Commande de fréquence de

l'accentuation des graves

Cette commande permet de choisir la

fréquence, entre 40 Hz et 120 Hz, autour

de laquelle doit s'effectuer

l'accentuation.

Témoin d'alimentation

Ce témoin s'éclaire lorsque

l'amplificateur est sous tension.

Commande d'amplitude de

l'accentuation des graves

Après avoir choisie la fréquence grave à

accentuer au moyen de la commande de

fréquence, il est possible de faire varier,

dans la plage de 0 à 12 dB, l'amplitude

des signaux au voisinage de cette

fréquence en agissant sur la commande

d'amplitude.

Commande de la fréquence

de coupure pour LPF

La fréquence de coupure peut être

choisie entre 40 et 240 Hz.

Commande du gain

Si le niveau d'écoute est faible même

lorsque la commande de l'autoradio est

sur la position correspondant au

maximum, tournez la commande de gain,

placée à l'avant de l'amplificateur, dans le

sens des aiguilles d'une montre.

Inversement, si vous constatez de la

distorsion lorsque vous augmentez le

niveau de sortie de l'autoradio, tournez

cette commande dans le sens contraire

des aiguilles d'une montre.

· Choisissez la position NORMAL si

l'autoradio stéréo est équipé de prises

Cinch (RCA) (niveau de sortie standard à

500 mV). Si cet appareil est utilisé

conjointement avec un autoradio stéréo

Pioneer pourvu de prises Cinch (RCA) sur

lesquelles peuvent se trouver une tension

de sortie de 4 V ou plus, réglez le niveau

en fonction du niveau de sortie de

l'autoradio.

· Pour la commande de gain de

l'amplificateur associé, reportez-vous à la

section "Réglage du gain de l'amplificateur

associé".

Sélecteur infrasonore

Le filtre infrasonore coupe les

fréquences inférieures à 20 Hz afin de

supprimer les vibrations indésirables et

de réduire les pertes de puissance.

Commutateur MODE SELECT

Vous pouvez sélectionner le mode de

synchronisation de l'amplificateur, à

savoir MASTER, SYNC et SYNC INV.

Pour ce qui concerne la position du

commutateur MODE SELECT, reportez-

vous à la section "Connexion des câbles

des haut-parleurs".
