This subwoofer system employs Advanced Yamaha
Active Servo Technology II which Yamaha has
developed for reproducing higher quality super-bass
sound. (Refer to page 14 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 front 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.
You can select bass effect suitable for the source by
using the B.A.S.S. button.
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, : 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 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. or .
Note
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.

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 Make sure that the POWER switch is set to the ON
position, then press the STANDBY/ON button to turn
on the subwoofer.
* The Power indicator lights up in green.
4 Play a source containing low-frequency components
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 front speaker’s rated minimum reproducible
frequency*.
* The front 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 front 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.
8 Select “MOVIE” or “MUSIC” according to the played
source.
MOVIE:
When a movie type source is played, the low-
frequency effects are enhanced to allow the listeners
enjoy more powerful sound. (The sound will be thicker
and deeper.)
MUSIC:
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 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
control and the PHASE switch, refer to “Frequency
characteristics” on page 13.

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.

•I
nstaller 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.
Pour prévenir tout dégât dû à la foudre, débrancher la
prise d’alimentation CA en cas d’orage.
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.
