Thank you for selecting this YAMAHA subwoofer system.

Please read the following operating precautions before use.

YAMAHA will not be held responsible for any damage and/or

injury caused by not following the cautions below.

• To assure the finest performance, please read this manual

carefully. Keep it in a safe place for future reference.

• Install this unit in a cool, dry, clean place - away from windows,

heat sources, sources of excessive vibration, dust, moisture and

cold. Avoid sources of humming (transformers, motors). To

prevent fire or electrical shock, do not expose this unit to rain or

water.

• Never open the cabinet. If something drops into the set, contact

your dealer.

• The voltage to be used must be the same as that specified on the

rear panel. Using this unit with a higher voltage than specified

is dangerous and may cause a fire and/or electric shock.

• To reduce the risk or fire or electric shock, do not expose this

unit to rain or moisture.

• Do not use force on switches, controls or connection wires.

When moving the unit, first disconnect the power plug and the

wires connected to other equipments. Never pull the wires

themselves.

• When not planning to use this unit for a long period (ie.,

vacation, etc.), disconnect the AC power plug from the wall

outlet.

• Since this unit has a built-in power amplifier, heat will radiate

from the rear panel. Place the unit apart from the walls, allowing

at least 20 cm of space above, behind and on both sides of the

unit to prevent fire or damage. Furthermore, do not position

with the rear panel facing down on the floor or other surfaces.

• Do not cover the rear panel of this unit with a newspaper, a

tablecloth, a curtain, etc. in order not to obstruct heat radiation.

If the temperature inside the unit rises, it may cause fire,

damage to the unit and/or personal injury.

• Do not place the following objects on this unit:

- Glass, china, small metallic etc.

If glass etc. falls by vibrations and breaks, it may cause bodily

injury.

- A burning candle etc.

If the candle falls by vibrations, it may cause fire and bodily

injury.

- A vessel with water in it

If the vessel falls by vibrations and water spills, it may cause

damage to the speaker, and/or you may get an electric shock.

• Do not place this unit where foreign objects such as water drips

might fall. It might cause a fire, damage to this unit, and/or

personal injury.

• Never put a hand or a foreign object into the YST port located

on the right side of this unit. When moving this unit, do not hold

the port as it might cause personal injury and/or damage to this

unit.

• Never place a fragile object near the YST port of this unit. If the

object falls or drops by the air pressure, it may cause damage to

the unit and/or personal injury.

• Never open the cabinet. It might cause an electric shock since

this unit uses a high voltage. It might also cause personal injury

and/or damage to this unit.

• When using a humidifier, be sure to avoid condensation inside

this unit by allowing enough spaces around this unit or avoiding

excess humidification. Condensation might cause a fire,

damage to this unit, and/or electric shock.

• Super-bass frequencies reproduced by this unit may cause a

turntable to generate a howling sound. In such a case, move this

unit away from the turntable.

• This unit may be damaged if certain sounds are continuously

outputted at high volume level. For example, if 20 Hz-50 Hz

sine waves from a test disc, bass sounds from electronic

instruments, etc. are continuously outputted, or when the stylus

of a turntable touches the surface of a disc, reduce the volume

level to prevent this unit from being damaged.

• If you hear distorted noise (i.e., unnatural, intermittent

“rapping” or “hammering” sounds) coming from this unit,

reduce the volume level. Extremely loud playing of a movie

soundtrack’s low frequency, bass-heavy sounds or similarly

loud popular music passages can damage this speaker system.

• Vibration generated by super-bass frequencies may distort

images on a TV. In such a case, move this unit away from the

TV set.

• Do not attempt to clean this unit with chemical solvents as this

might damage the finish. Use a clean, dry cloth.

• Be sure to read the “TROUBLESHOOTING” section regarding

common operating errors before concluding that the unit is

faulty.

• Install this unit near the wall outlet and where the AC power

plug can be reached easily.

• Secure placement or installation is the owner’s

responsibility. YAMAHA shall not be liable for any

accident caused by improper placement or installation of

speakers.

CAUTION: Read this before operating your unit.

This unit features a magnetically shielded design, but

there is still a chance that placing it too close to a TV set

might impair picture color. Should this happen, move

this unit away from the TV set.

( : subwoofer, : front speaker)

One subwoofer will have a good effect on your audio

system, however, the use of two subwoofers is

recommended to obtain more effect.

If using one subwoofer, it is recommended to place it on

the outside of either the right or the left front speaker. (See

fig. .) If using two subwoofers, it is recommended to

place them on the outside of each front speaker. (See

fig. .) The placement shown in fig. is also possible,

however, if the subwoofer system is placed directly facing

the wall, the bass effect may lessen because the sound from

it and the sound reflected by the wall may cancel out each

other. To prevent this from happening, face the subwoofer

system at an angle as in fig. or .

There may be a case that you cannot obtain enough super-

bass sounds from the subwoofer when listening in the

center of the room. This is because “standing waves” have

been developed between two parallel walls and they cancel

the bass sounds.

In such a case, face the subwoofer obliquely to the wall. It

also may be necessary to break up the parallel surfaces by

placing bookshelves etc. along the walls.

Use the non-skid pads

Put the provided non-skid pads at the four corners on the

bottom of the subwoofer to prevent the subwoofer from

moving by vibrations etc.

For connection, keep the speaker cables as short as

possible. Do not bundle or roll up the excess part of the

cables. If the connections are faulty, no sound will be heard

from the subwoofer or the speakers, or both of them. Make

sure that the + and – polarity markings of the speaker

cables are observed and set correctly. If these cables are

reversed, the sound will be unnatural and lack bass.

Caution

Do not let the bare speaker wires touch each other, because

this could damage the subwoofer or the amplifier, or both of

them.

■ Before connecting

Remove the insulation coating at the extremity of each

speaker cable by twisting the coating off.

■ How to connect:

1 Press and hold the terminal’s tab, as shown in the

figure.

2 Insert the bare wire.

3 Release your finger from the tab to allow it to lock

securely on the cable’s wire end.

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer

and the front speakers by following the procedures described below.

1 Set the VOLUME control to minimum (0).

2 Turn on the power of all the other components.

3 Press the POWER switch to the ON position.

* The Power indicator lights up in green.

4 Play a source containing bass signal and adjust the

amplifier’s volume control to the desired listening

level.

5 Set the HIGH CUT switch to the LOW or HIGH

position.

This subwoofer is designed so that the optimum tone

balance between the subwoofer and the front

speakers is obtained when this HIGH CUT switch is

set to the LOW position. The tone balance may

change, however, depending on the room size, the

distance from the subwoofer to the front speakers,

and so on. If necessary, switch it to the HIGH

position.

6 Rotate the VOLUME control gradually to adjust the

volume balance between the subwoofer and the other

speakers.

* Normally, set the control to the level where you can

obtain a little more bass effect than when the

subwoofer is not used. If the desired response cannot

be obtained, adjust the HIGH CUT switch and the

VOLUME control again.

• Once the volume balance between the subwoofer and

the front speakers is adjusted, you can adjust the

volume of your whole sound system by using the

amplifier’s volume control.

However, if you change the front speakers to others,

you must make this adjustment again.

• For adjusting the VOLUME control, the HIGH CUT

switch, refer to “Frequency characteristics” on page

10.

English

In 1988, Yamaha brought to the marketplace speaker

systems utilizing YST (Yamaha Active Servo Technology)

to give powerful, high quality bass reproduction. This

technique uses a direct connection between the amplifier

and speaker, allowing accurate signal transmission and

precise speaker control.

As this technology uses speaker units controlled by the

negative impedance drive of the amplifier and resonance

generated between the speaker cabinet volume and port, it

creates more resonant energy (the “air woofer” concept)

than the standard bass reflex method. This allows for bass

reproduction from much smaller cabinets than was

previously possible.

Yamaha’s newly developed Advanced YST II adds many

refinements to Yamaha Active Servo Technology,

allowing better control of the forces driving the amplifier

and speaker. From the amplifier’s point of view, the

speaker impedance changes depending on the sound

frequency. Yamaha developed a new circuit design

combining negative-impedance and constant-current

drives, which provides a more stable performance and

clear bass reproduction without any murkiness.

• En utilisant un humidificateur, éviter la condensation à

l’intérieur de l’appareil en libérant la place autour de l’appareil

ou en évitant l’humidification extrême. La condensation peut

causer un feu, des dommages à l’appareil et/ou une

électrocution.

• Les sons de très basse fréquence produits par cet appareil

peuvent provoquer un sifflement sur le tourne-disque. Dans ce

cas, éloigner cet appareil du tourne-disque.

• Cet appareil peut être endommagé si certains sons sont

continuellement émis à un niveau sonore élevé. Par exemple, si

des ondes sinusoïdales de 20 Hz-50 Hz d’un disque d’essai, des

sons de graves d’instruments électroniques, etc. sont émis en

continu ou si la pointe de lecture d’une platine tourne-disque

touche la surface d’un disque, réduire le niveau de volume pour

éviter d’endommager cet appareil.

• Si une distorsion se fait entendre (par exemple des petits coups

secs intermittents ou un “martèlement”) sur cet appareil,

diminuer le niveau sonore. La lecture à très haut volume des

sons de basse ou des sons de basses fréquences de la bande

sonore d’un film, ou de passages de musique pop de forte

intensité, sont susceptibles d’endommager ce système

d’enceintes.

• Des vibrations générées par des fréquences supergraves

risquent de déformer les images sur un téléviseur. Dans ce cas,

éloigner cet appareil du téléviseur.

• Ne pas essayer de nettoyer cette unité avec des diluants

chimiques, ceci endommagerait le fini. Utiliser un chiffon

propre et sec.

• Bien lire la section “RESOLUTION DES PROBLEMES”

concernant les erreurs de fonctionnement communes avant de

conclure que l’unité est défecteuse.

• Installez l’appareil près de la prise secteur et à un endroit tel que

la fiche secteur soit facilement accessible.

• Le propriétaire du système est entièrement responsable du

bon positionnement et de la bonne installation du système.

YAMAHA décline toute responsabilité en cas d’accident

causé par un positionnement ou une installation inadéquats

des enceintes.

ATTENTION: Tenir compte des précautions ci-dessous

avant de faire fonctionner l’appareil.

Même si cette unité dispose d’une conception à

blindage magnétique, il y a un risque possible de

création d’interférences, visibles sur les images en

couleurs si elle est placée à côté d’un téléviseur. Dans ce

cas, éloigner l’unité du téléviseur.

Tant que l’appareil est raccordé à la prise secteur, il

reste connecté au secteur même si vous le mettez hors

tension avec POWER.

• Ce subwoofer utilise la technologie Advanced Yamaha

Active Servo Technology II mise au point par Yamaha

pour la reproduction de basses fréquences de meilleure

qualité. (Pour ce qui concerne Advanced Yamaha Active

Servo Technology II, se reporter à la page 11.) Ces

basses fréquences ajoutent un effet réaliste

cinématographique aux sons fournis par une chaîne

stéréo.

• Ce subwoofer peut être facilement ajouté à votre chaîne

actuelle en le raccordant soit aux bornes d’enceintes soit

aux bornes de sortie de ligne (fiche jack) de

l’amplificateur.

• Le sélecteur HIGH-CUT permet de régler l’équilibre du

son entre le caisson de graves et les enceintes avant sur

l’une de deux positions (HIGH ou LOW).

Vérifier que les pièces suivantes sont comprises dans la

boîte lors du déballage.

Tampons anti-dérapage (1 jeu, 4 patins)

VOLTAGE SELECTOR

(Modèle pour l’Asie et modèle général)

Le commutateur de tension situé sur le panneau arrière de l’unité doit être placé dans la position adéquate

AVANT de brancher l’unité dans la prise CA du secteur. Les tensions sont de 110-120/220-240 V CA, 50/60 Hz.

( : subwoofer, : enceinte avant)

L’utilisation d’un seul subwoofer dans une chaîne donne

déjà de bons résultats, cependant l’utilisation de deux

subwoofers est recommandée pour accroître l’effet du son.

Lorsqu’on utilise un seul subwoofer, il est recommandé de

le placer sur le côté extérieur de l’enceinte principale droite

ou gauche. (Voir la fig. .) Lorsqu’on utilise deux

subwoofers, il est recommandé de les placer sur le côté

extérieur de chacune des enceintes principales. (Voir la fig.

.) Il est également possible de positionner les enceintes

comme indiqué à la fig. ; cependant, si le subwoofer est

placé directement contre le mur, l’effet de basse pourra se

trouver supprimé car le son émis par l’enceinte et le son

renvoyé par le mur s’annuleront mutuellement. Pour éviter

ce problème, placer le subwoofer à angle oblique par

rapport au mur, comme indiqué sur la fig. ou .

Les sons de très basses fréquences du subwoofer peuvent

parfois être trop faiblement perçus à partir d’une position

d’écoute en milieu de pièce. Les ondes renvoyées par deux

murs parallèles peuvent en effet s’annuler mutuellement et

supprimer les sons de basses.

Dans un tel cas, diriger le subwoofer obliquement par

rapport au mur. Il peut être également nécessaire de

modifier le parallélisme des surfaces murales en plaçant

des étagères etc. le long des murs.

Utiliser les tampons anti-dérapage

Mettre les tampons anti-dérapage fournis aux quatre coins

du bas du subwoofer afin d’empêcher le subwoofer de

bouger sous l’effet des vibrations, etc.

Choisir la méthode (pages 3-4) pour obtenir un son d’ambiance sur 5.1

voies

■ Choisir la méthode (pages 5-6) pour que les signaux basses fréquences

Précautions d’usage : Débrancher le subwoofer et les autres composants audio/video avant

d’effectuer les connexions.

• Tous les branchements doivent être effectués correctement, c’est-à-dire entre L (gauche) et L, entre R (droite) et R, entre

“+” et “+” et entre “–” et “–”. Voir aussi le mode d’emploi de chacun des appareils devant être connectés au subwoofer.

• Brancher le subwoofer et les autres composants audio/vidéo après avoir accompli tous les raccordements.

• Pour un branchement avec un amplificateur YAMAHA DSP (ou un récepteur AV), connecter la borne SUBWOOFER

(ou LOW PASS etc.) située à l’arrière de l’amplificateur DSP (ou du récepteur AV) à la borne /MONO INPUT2 du

subwoofer.

• Lorsqu’on raccorde le subwoofer aux bornes SPLIT SUBWOOFER à l’arrière de l’amplificateur DSP, veiller à

raccorder la borne /MONO INPUT2 au côté “L” et les bornes INPUT2 au côté “R” des bornes SPLIT

SUBWOOFER.

• Certains amplificateurs possèdent des bornes de sortie de ligne nommées PRE OUT. Lorsque l’on raccorde le

subwoofer aux bornes PRE OUT de l’amplificateur, veiller à ce que l’amplificateur possède au moins deux jeux de

bornes PRE OUT. Si l’amplificateur ne possède qu’un seul jeu de bornes PRE OUT, ne pas raccorder le subwoofer aux

bornes PRE OUT. Raccorder plutôt le subwoofer aux bornes de sortie d’enceintes de l’amplificateur. (Se reporter aux

pages 5-6.)

• Pour faire un raccordement à une borne de sortie de ligne mono de l’amplificateur, raccorder la borne /MONO

INPUT2 à cette borne.

• Lorsque l’appareil est raccordé aux bornes de sortie de ligne, aucune autre enceinte ne doit être raccordée aux bornes

OUTPUT du panneau arrière du subwoofer. Cette enceinte ne produirait alors aucun son.
