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 equipment. Never
pull the wires themselves.
● When not planning to use this unit for a long period (i.e.
vacation, etc.), disconnect the AC power plug from the
wall outlet.
● To prevent lightning damage, disconnect the AC power
plug when there is an electric storm.
● Since this unit has a built-in power amplifier, heat will
radiate from the rear panel. Place the unit apart from the
walls, allowing enough spaces 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.
Be sure to allow spaces of at least 20 cm above, behind
and on both sides of the unit.
● 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 small metallic objects on this unit.
Otherwise, the object may fall, possibly causing an injury.
● Do not place the following objects on this unit:
Glass, china, etc.
If glass etc. falls by vibrations and breaks, it may cause
personal injury.
A burning candle etc.
If the candle falls by vibrations, it may cause fire and
personal injury.
A vessel with water in it
If the vessel falls by vibrations and water spills, it may
cause damage to the unit, 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 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 put a hand or a foreign object into the YST port
located on the front 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 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

● 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.
Standby mode
When this unit is turned off by pressing the STANDBY/ON
button on the front panel, this unit consumes a small
amount of power. This state is called the standby mode.
This unit’s power supply is completely cut off from the AC
line only when the POWER switch is set in the OFF
position or the AC power cable is disconnected.
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.
FOR CANADIAN CUSTOMERS
To prevent electric shock, match wide blade of plug to
wide slot and fully insert.
This Class B digital apparatus complies with Canadian
ICES-003.

FEATURES
● This subwoofer system employs Advanced
YAMAHA Active Servo Technology which YAMAHA
has developed for reproducing higher quality
super-bass sound. (Refer to page 18 for details on
Advanced YAMAHA Active Servo Technology.) This
super-bass sound adds a more realistic, theater-inthe-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 button.
● You can make setting changes and adjustments for
the subwoofer by using the remote control without
moving from your listening position.
E-2
● The Automatic power-switching function saves you
the trouble of pressing the STANDBY/ON button to
turn the power on and off.
● You can select bass effect suitable for the source
by using the B.A.S.S. button.
● The use of the H.P.F. OUTPUT terminals for
connecting with the amplifier is effective for
improving sound quality of your speaker system.
This connection prevents sound output from the
main speakers from muddying by filtering out low
frequencies of input signals to be sent to the main
speakers which are not suitable for reproducing
low frequencies.
QD-Bass Technology
QD-Bass (Quatre Dispersion Bass) technology uses
square, pyramid-shaped reflective plates to radiate the
sound in four horizontal directions.
PLACEMENT
English
Å
( : 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 fig.
Å.) If using two subwoofers, it is recommended to place
them on the outside of each main speaker. (See fig. ı.)
The placement shown in fig. Ç 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 fig. Å or ı.
Çı
Note
There may be a case that you cannot obtain enough superbass 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.
E-3
CONNECTIONS
Caution: Plug in the subwoofer and other audio/video components after all connections are
completed.
● All connections must be correct, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also refer to the owner’s
manual for each of your components.
● The subwoofer can be connected to either the line output (pin jack) terminals or the speaker output terminals of the amplifier.
Choose one of the ways shown in this section that is more suitable for your audio system. Also, refer to the owner’s manual
of your component to be connected to the subwoofer.
Basically, connect the subwoofer to the line output (pin jack) terminal(s) of the amplifier. (Refer to pages 4 and 5 for details.)
If your amplifier does not have any line output terminal, connect the subwoofer to the speaker output terminals of the
amplifier. (Refer to pages 6 and 7 for details.)
Connecting to line output (pin jack) terminals of the amplifier
Connect the main speakers to the speaker output terminals of the amplifier.
● To connect with a YAMAHA DSP amplifier (or AV
receiver), connect the SUBWOOFER (or LOW PASS etc.)
terminal on the rear of the DSP amplifier (or AV receiver)
to the L/MONO INPUT2 terminal of the subwoofer.
Using one subwoofer
● When connecting the subwoofer to the SPLIT
SUBWOOFER terminals on the rear of the DSP amplifier,
be sure to connect the L/MONO INPUT2 terminal to the
“L” side and the R INPUT2 terminal to the “R” side of the
SPLIT SUBWOOFER terminals.

Connecting to the LFE (INPUT3) terminal(s)
If your amplifier can cut off high frequencies from the signals for sending to the
subwoofer, connect the amplifier to the subwoofer’s LFE (INPUT3) terminal(s). This
will bring you higher sound quality because the signal routing in the subwoofer is
shortened bypassing the built-in HIGH CUT circuit.
Notes
● Some amplifiers have line output terminals labelled PRE
OUT. When you connect the subwoofer to the PRE OUT
terminals of the amplifier, make sure that the amplifier
has at least two sets of PRE OUT terminals. If the
amplifier has only one set of PRE OUT terminals, do not
connect the subwoofer to the PRE OUT terminals.
Instead, connect the subwoofer to the speaker output
terminals of the amplifier. (Refer to pages 6 and 7.)
● When connecting to a monaural line output terminal of
the amplifier, connect the L/MONO INPUT2 terminal.
● When connecting to line output terminals of the amplifier,
other speakers should not be connected to the OUTPUT
terminals on the rear panel of the subwoofer. If
connected, they will not produce sound.

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.

Connecting to H.P.F. OUTPUT terminals
The use of the H.P.F. OUTPUT terminals for connections with the amplifier will improve sound quality of your speaker system.
The H.P.F. (High-Pass Filter) OUTPUT terminals of the subwoofer cut off frequencies below the selected frequency point from
the input signals, and output high frequencies only. By connecting this terminal with the MAIN IN terminals of the amplifier, the
main speakers reproduce high frequencies only.
This will make the whole sound quality clear by preventing sound muddying between the main speakers and the subwoofer.
* This connection can be made if your amplifier has PRE OUT and MAIN IN terminals or you are using separate amplifiers
(pre-amplifier and main amplifier).

AUTOMATIC POWER-SWITCHING FUNCTION
If the source being played is stopped and the input signal is
cut off for 7 to 8 minutes, the subwoofer automatically
switches to the standby mode. (When the subwoofer
switches to the standby mode by the automatic powerswitching function, the power indicator lights up in red.)
When you play a source again, the power of the subwoofer
turns on automatically by sensing audio signals input to the
subwoofer.
This function operates by sensing a certain level of low
frequency input signal. Usually set the AUTO STANDBY
switch to the LOW position. However, if the power is not
switched to ON or STANDBY smoothly, set the switch to the
HIGH position. In the HIGH position, the power will turn on
even with a low level of input signal. But please be aware
that the subwoofer may not switch to the standby mode
when there is an extremely low input signal.
* The power might turn on unexpectedly by sensing noise
from other appliances. If that occurs, set the AUTO
STANDBY switch to the OFF position.
* This function detects the low-frequency components
below 200 Hz of the input signals (i.e., the explosion in
the action movie, the sound of the bass guitar or the bass
drum, etc.).
* The minutes required to switch the subwoofer to the
standby mode might change by sensing noise from other
appliances.
This function is available only when the power of the
subwoofer is on (by setting the STANDBY/ON button to
“ON”).
This function will not work if the subwoofer is turned
into the standby mode by using the STANDBY/ON
button. (The power indicator on the front panel goes
off.)

MUSIC (when the MUSIC/MOVIE indicator on the front
panel lights up in red):
When an ordinary music source is played, the excessive
low-frequency components are cut off to make the
sound clearer. (The sound will be lighter and reproduces the melody line more clearly.)
• 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.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY
The theory of Yamaha Active Servo Technology has been
based upon two major factors, the Helmholtz resonator and
negative-impedance drive. Active Servo Processing
speakers reproduce the bass frequencies through an “air
woofer”, which is a port or opening in the speaker’s cabinet.
This opening is used instead of, and performs the functions
of, a woofer in a conventionally designed speaker system.
Thus, signals of low amplitude within the cabinet can,
according to the Helmholtz resonance theory, be outputted
from this opening as waves of great amplitude if the size of
the opening and the volume of the cabinet are in the correct
proportion to satisfy a certain ratio.
In order to accomplish this, moreover, the amplitudes within
the cabinet must be both precise and of sufficient power
because these amplitudes must overcome the “load”
presented by the air that exists within the cabinet.
Thus it is this problem that is resolved through the
employment of a new design in which the amplifier supplies
special signals. If the electrical resistance of the voice coil
could be reduced to zero, the movement of the speaker unit
would become linear with respect to signal voltage. To
accomplish this, a special negative-impedance output-drive
amplifier for subtracting output impedance of the amplifier is
used.
By employing negative-impedance drive circuits, the
amplifier is able to generate precise, low-amplitude, lowfrequency waves with superior damping characteristics.
These waves are then radiated from the cabinet opening as
high-amplitude signals. The system can, therefore, by
employing the negative-impedance output drive amplifier
and a speaker cabinet with the Helmholtz resonator,
reproduce an extremely wide range of frequencies with
amazing sound quality and less distortion.
The features described above, then, are combined to be the
fundamental structure of the conventional Yamaha Active
Servo Technology.
Our new Active Servo Technology — Advanced Yamaha
Active Servo Technology — adopted Advanced Negative
Impedance Converter (ANIC) circuits, which allows the
conventional negative impedance converter to dynamically
vary in order to select an optimum value for speaker
impedance variation. With this new ANIC circuits, Advanced
Yamaha Active Servo Technology can provide more stable
performance and improved sound pressure compared with
the conventional Yamaha Active Servo Technology, resulting
in more natural and dynamic bass reproduction.

CARACTERISTIQUES
● Ce subwoofer utilise la Advanced YAMAHA Active
Servo Technology mise au point par YAMAHA pour
une reproduction des basses fréquences de
meilleure qualité. (Reportez-vous à la page 18
pour plus de détails sur la technologie Advanced
YAMAHA Active Servo Technology.) Le son à super
basses ajoute plus de réalisme, et un effet cinéma-
à-domicile à votre système 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 Cinch) de l’amplificateur.
● Pour utiliser au mieux les possibilités de ce
subwoofer, les basses fréquences de ce subwoofer
doivent être harmonisées avec les sons des
enceintes principales. De plus, il est possible
d’optimiser la qualité sonore suivant les conditions
d’écoute au moyen de la commande HIGH CUT
et de la touche PHASE.
● Vous pouvez modifier les réglages du subwoofer
à l’aide de la télécommande sans avoir à quitter
votre position d’écoute.
F-2
●
La fonction de commutation d’alimentation automatique
évite d’avoir à appuyer sur la touche STANDBY/ON
pour mettre le subwoofer sous et hors tension.
● Il est possible de sélectionner un effet de basses
convenant à la source à l’aide de la touche
B.A.S.S.
● L’utilisation des bornes H.P.F. OUTPUT pour la
connexion de l’amplificateur sert beaucoup à
améliorer la qualité du son de votre système
d’enceinte.
Ce branchement empêche la transmission des
basses fréquences du signal d’entrée vers les
enceintes principales qui ne sont pas adaptées
à leur reproduction, annulant par conséquent les
effets nuisibles de cette mauvaise reproduction.
Technologie QD-Bass
La technologie QD-Bass (Quatre Dispersion Bass)
utilise des plaques réfléchissantes carrées, de forme
pyramidale pour rayonner le son dans les quatre
directions horizontales.
POSITIONNEMENT
Å
( : subwoofer, : enceintes principales)
L’utilisation d’un seul subwoofer dans une chaîne donne
déjà de bons résultats, cependant l’utilisation de deux
subwoofer 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. Å.) Lorsqu’on utilise deux
subwoofers, il est recommandé de les placer sur le côté
extérieur de chacune des enceintes principales. (Voir la fig.
ı.) Il est également possible de positionner les enceintes
comme indiqué à la fig. Ç; 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. Å ou ı.

Remarque
Les sons de très basses fréquences du subwoofer peuvent
quelquefois être trop faiblement perçus à partir d’une
position d’écoute en milieu de pièce. Les “ondes
stationnaires” 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.

RACCORDEMENTS
Attention: Brancher le subwoofer et les autres composants audio/vidéo après avoir accompli
tous les raccordements.
● 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.
● Le subwoofer peut être raccordé soit aux bornes de sortie de ligne (fiche Cinch) soit aux bornes de sortie d’enceintes de
l’amplificateur. Choisir parmi les possibilités illustrées dans ce chapitre celle qui convient le mieux à votre chaîne. Voir aussi
le mode d’emploi de l’appareil branché au subwoofer.
Fondamentalement, raccorder le subwoofer à la (aux) borne(s) de sortie de ligne (fiche Cinch) de l’amplificateur. (Pour plus
de détails, se reporter aux pages 4 et 5.) Si l’amplificateur n’est pas équipé d’une borne de sortie de ligne, raccorder le
subwoofer aux bornes de sortie d’enceintes de l’amplificateur. (Pour plus de détails, se reporter aux pages 6 et 7.)
Raccordement aux bornes de sortie de ligne (fiche Cinch) de l’amplificateur
Raccorder les enceintes principales aux bornes de sortie d’enceintes de l’amplificateur.
●
Pour effectuer le raccordement à un amplificateur
YAMAHA DSP (ou récepteur AV), raccorder la borne
SUBWOOFER (ou LOW PASS, etc.) située à l’arrière de
l’amplificateur DSP (ou récepteur AV) à la borne L/MONO
INPUT2.
Utilisation d’un seul subwoofer
● Lorsqu’on raccorde le subwoofer aux bornes SPLIT
SUBWOOFER à l’arrière de l’amplificateur DSP, veiller à
raccorder la borne L/MONO INPUT2 au côté “L” et les
bornes R INPUT2 au côté “R” des bornes SPLIT
SUBWOOFER.

Branchement aux bornes LFE (INPUT3)
Si votre amplificateur peut couper les hautes fréquences du signal envoyé vers le
subwoofer, branchez-le aux bornes LFE (INPUT3) du subwoofer. Ceci améliorera
la qualité du son car le signal passera directement vers le subwoorer sans avoir à
passer par le circuit HIGH CUT incorporé.
Remarques
● 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 6 et 7.)
● Pour faire un raccordement à une borne de sortie de
ligne mono de l’amplificateur, raccorder la borne L/
MONO INPUT2 à cette borne.
● Lorsque l’appareil est raccordé aux bornes de sortie de
ligne, aucune autre enceinte ne doit pas être raccordée
aux bornes OUTPUT du panneau arrière du subwoofer.
Cette enceinte ne produirait alors aucun son.

Branchement aux bornes INPUT1/OUTPUT du subwoofer
Pour les raccordements, laisser les câbles d’enceintes aussi
courts que possible. Ne pas plier ni enrouler la partie en
excès des câbles. Si les connexions sont mal effectuées,
aucun son ne saura émis par le subwoofer ou par les
enceintes, ou par les deux. S’assurer que les marquages
de polarité + et – des câbles d’enceinte sont respectés et
placés correctement. Si ces câbles sont inversés, le son
ne sera pas naturel et manquera de graves.
Raccordement:
Mauvais
Rouge : positif (+)
Noir : négatif (–)
Bon
PRECAUTIONS D’USAGE :
Veiller à ce que les fils dénudés ne se touchent pas car
ceci pourrait abîmer le subwoofer, l’amplificateur ou les
deux appareils.
<Uniquement pour les modèles pour les Etats-Unis,
le Canada, l’Australie et la Corée
Les branchements avec fiche Cinch sont aussi possibles.

Raccordement aux bornes H.P.F. OUTPUT
L’utilisation des bornes H.P.F. OUTPUT pour les branchements de l’amplificateur améliore la qualité du son de votre système
d’enceintes.
Le H.P.F. (Filtre passe-haut) des bornes OUTPUT du subwoofer coupe les fréquences inférieures à une fréquence particulière
du signal d’entrée, et laisse passer les hautes fréquences uniquement. En branchant cette borne aux bornes MAIN IN de
l’amplificateur, les enceintes principales reproduiront uniquement les hautes fréquences.
Ceci améliorera la qualité du son en empêchant la mauvaise reproduction du son par les enceintes et le subwoofer.
* Il est possible d’effectuer ce branchement si votre amplificateur dispose de bornes PRE OUT et MAIN IN, ou en cas
d’utilisation d’amplificateurs séparés (pré-amplificateur et amplificateur principal).
