Thank you for selecting this YAMAHA subwoofer system.
CAUTION: Read this before operating your unit.
1. To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
2. 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 the unit to rain or water.
3. Never open the cabinet. If something drops into the
set, contact your dealer.
4. 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.
5. Do not attempt to clean the unit with chemical solvents
as this might damage the finish. Use a clean, dry
cloth.
6. Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before concluding
that the unit is faulty.
7. When not planning to use this unit for a long period
(ie., vacation, etc.), disconnect the AC power plug from
the wall outlet.
8.
To prevent lightning damage, disconnect the AC power
plug when there is an electric storm.
9. 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 space above, behind and on
the 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.
10. 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.
11. Vibration generated by super-bass frequencies may
cause images on a TV to be distorted. In such a case,
move this unit away from the TV set.
12. This unit features a magnetically shielded design, but it
is still possible for the picture color to be impaired when
the subwoofer is placed too close to a TV set. Should
this happen, move this unit away from the TV set.
13. 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.
14. 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.
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
English
● This subwoofer system employs Advanced YAMAHA
Active Servo Technology which YAMAHA has developed
for reproducing higher quality super-bass sound. (Refer
to page 11 for details on Advanced YAMAHA Active
Servo Technology.) 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.
PLACEMENT
Å
● The HIGH CUT switch provides you with two positions
(HIGH and LOW) to adjust the tone balance between the
subwoofer and the main speakers.
● The AUTO STANDBY switch saves you the trouble of
setting the POWER s witch to the ON or OFF position.
Çı
( : 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.
Note
There may be a case that you cannot obtain enough superbass sounds from the subwoofer when listening at the
middle 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.
