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

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.

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
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.
䡵 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.
