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 equipment. 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

output 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 output, 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.

This unit is not disconnected from the AC power source

as long as it is connected to the wall outlet, even if this

unit itself is turned off. In this state, this unit is designed

to consume a very small quantity of power.

• This subwoofer system employs Advanced Yamaha

Active Servo Technology II, which Yamaha has

developed for reproducing higher quality super-bass

sound (refer to page 15 for details on Advanced Yamaha

Active Servo Technology II). This super-bass sound

adds a more realistic, theater-in-the-home effect to your

stereo system.

• This subwoofer can be easily added to your existing

audio system by connecting to either the speaker

terminals or the line output (pin jack) terminals of the

amplifier.

• For the effective use of the subwoofer, the subwoofer’s

super-bass sound should be matched to the sounds of

your main speakers. You can create the best sound

quality for various listening conditions by using the

HIGH CUT control and the PHASE switch.

• The Automatic power-switching function saves you the

trouble of pressing the STANDBY/ON button to turn the

power on and off.

• This subwoofer system is equipped with a linear port

unique to Yamaha that provides smooth bass response

during playback, minimizing extraneous noise not

included in the original input signal.

After unpacking, check that the following parts are

contained.

( : subwoofer : main 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 main speaker (see

A). If using two subwoofers, it is recommended to place

them on the outside of each main speaker (see B). The

placement shown in C is also possible, however, if the

subwoofer system is placed directly facing the wall, the

bass effect may die 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 A or B.

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.

2 Turn on the power of all the other components.

3 Make sure that the POWER switch on the rear panel is

set to the ON position, then press the STANDBY/ON

switch on the front panel to turn on the subwoofer.

* The status indicator lights up in green.

4 Play a source containing low-frequency signals and

adjust the amplifier’s volume control to the desired

listening level.

5 Adjust the HIGH CUT control to the position where

the desired response can be obtained. Normally, set the

control to the level a little higher than the main

speaker’s rated minimum reproducible frequency*.

* The main speaker’s rated minimum reproducible

frequency can be looked up in the speakers’ catalog

or owner’s manual.

6 Increase the volume gradually to adjust the volume

balance between the subwoofer and the main 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 control and the

VOLUME control again.

7 Set the PHASE switch to the position which gives you

the better bass sound. Normally, set the switch to the

REV (reverse) position. If the desired response cannot

be obtained, set the switch to the NORM (normal)

position.

• Once the volume balance between the subwoofer and

the main 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 main speakers to others, you must make this

adjustment again.

• For adjusting the VOLUME control, the HIGH CUT

control and the PHASE switch, refer to

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 bass

reproduction from much smaller cabinets than before.

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.

Nous vous remercions d’avoir porté votre choix sur ce subwoofer de Yamaha.

Tenir compte des précautions ci-dessous avant de faire

fonctionner l’appareil. Yamaha ne saurait être tenue pour

responsable de tout dommage et/ou blessure dûs à un non-respect

des mises en garde ci-dessous.

• Pour garantir les meilleures performances possibles, lire ce

manuel avec attention. Le garder dans un endroit sûr

pour une utilisation ultérieure.

• Installer cette unité dans un endroit frais, sec et propre - loin des

fenêtres, sources de chaleur et d’endroits où les vibrations, la

poussière, l’humidité ou le froid sont importants. Eviter les

sources de bourdonnements (transformateurs, moteurs). Pour

éviter les incendies ou les électrocutions, ne pas exposer cette

unité à la pluie ni à l’humidité.

• Ne jamais ouvrir le boîtier. Si quelque chose tombe dedans,

contacter immédiatement le revendeur.

• La tension à utiliser doit être la même que celle spécifiée sur le

panneau arrière. Utiliser cet appareil avec une plus haute

tension que celle spécifiée est dangereux et peut causer un

incendie et/ou causer une électrocution.

• Afin d’éviter tout risque d’incendie ou d’électrocution, ne pas

exposer cet appareil à la pluie ni à l’humidité.

•N

e pas forcer les commutateurs, les touches ou les câbles de

raccordement. Lors du déplacement de l’appareil, d’abord débrancher

la prise d’alimentation et les câbles le raccordant à d’autres appareils.

Ne jamais tirer sur les cordons.

• Lorsqu on prévoit de ne pas utiliser cet appareil pendant

longtemps (pendant les vacances, par exemple), débrancher le

cordon d’alimentation CA de la prise murale.

• Cet appareil possédant un amplificateur intégré, de la chaleur

sera irradiée par le panneau arrière. Placer l’unité assez loin des

murs, en laissant toujours un espace de 20 cm au moins au-

dessus, au-dessous et des deux côtés de l’unité afin d’éviter les

risques d’incendie et de dommages. Ne pas positionner non plus

cet appareil dos au plancher ou à une autre surface.

• Ne couvrez pas le panneau arrière de cet appareil avec un journal, une

nappe, un rideau, etc. afin de ne pas empêcher la dissipation de

chaleur. Si la température à l’intérieur de cet appareil augmente, un

incendie peut se déclarer et endommager cet appareil et/ou causer une

blessure corporelle.

• Ne jamais placer les objets suivants sur cette unité :

- Des objets verres, de la vaissille, des petits objets metalliques,

etc.

Des blessures pourraient être causées par des débris de verre,

etc. dûs aux vibrations et aux brisures.

- Une bougie allumée, etc.

Si la bougie tombe sous l’effet des vibrations, elle risque de

provoquer un incendie et des blessures corporelles

.

- Un récipient contenant de l’eau

Si le récipient tombe sous l’effet des vibrations et que de l’eau

éclabousse l’enceinte, ceci risque de l’endommager

sérieusement, et/ou de provoquer des électrocutions.

• Ne pas mettre cette unité dans les endroits où des corps

étrangers, comme des jets d’eau par exemple, pourraient tomber

dedans. Ceci pourrait causer un incendie, endommager cette

unité, et/ou des blessures corporelles.

• Ne jamais introduire la main ou un corps étranger dans le port YST

situé sur le côté droit de cette unité. Ne jamais attraper l’unité par

l’orifice du port lors des déplacements, car ceci pourrait causer des

blessures corporelles et/ou endommager l’unité.

• Ne jamais placer un objet fragile à proximité du port YST de

cette unité. Si cet objet venait à chuter en raison de la pression

de l’air, il pourrait endommager l’unité et/ou causer des

blessures corporelles.

• Ne jamais ouvrir le boîtier. Ceci pourrait entraîner des

électrocutions, car cette unité fonctionne sous haute tension.

Ceci pourrait aussi causer des blessures corporelles et/ou

endommager l’unité.

• 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.

•B

ien lire la section “RESOLUTION DES PROBLEMES”

concernant les erreurs de fonctionnement communes avant de

conclure que l’unité est défecteuse.

• Installez cet appareil à proximité de la prise secteur et à un

emplacement où la fiche du câble d’alimentation est 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.

Cet appareil n’est pas déconnecté du secteur tant qu’il reste

branché á la prise de courant. En pareil cas, celui-ci

consomme une faible quantité d’électricité.
