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.

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.
The HIGH CUT switch provides you with two positions
(HIGH and LOW) to adjust the tone balance between the
subwoofer and the front speakers.
After unpacking, check that the following parts are
contained.
Non-skid pads (1 set, 4 pieces)
IMPORTANT:
THE WIRES IN MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
Blue: NEUTRAL
Brown: LIVE
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows: The wire which is coloured BLUE must be connected to
the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be
connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is
connected to the earth terminal of the three pin plug.

( : 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

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.

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.

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.
