CAUTION: Read this before operating your unit

Please read the following operating precautions before use.
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 (ie.,
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 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 as a result of vibrations and breaks,
it may cause bodily injury.

A burning candle etc.

If the candle falls as a result of vibration, it may cause
fire and bodily injury.

A vessel containing water

If the vessel falls as a result of vibration and water
spills, it may cause damage to the speaker, and/or you
may get an electric shock.

WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.

• Do not place this unit where foreign material, such as
dripping water. It might cause 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 as a result of 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 space around this
unit or avoiding excess humidification. Condensation
might cause 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 output 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
output, 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 distortion (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.

• Install this unit near the wall outlet and where the AC
power plug can be reached easily.

• 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.

Be sure to allow spaces of at least 20 cm above, behind
and on both sides of the unit.

This unit is not disconnected from the AC power
source as long as it is connected to the wall outlet, even
if this unit itself is turned off. In this state, this unit is
designed to consume a very small quantity of power.

This unit features a magnetically shielded design,
however, 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 U.K. customers

If the socket outlets in the home are not suitable for the
plug supplied with this appliance, it should be cut off and
an appropriate 3 pin plug fitted. For details, refer to the
instructions described below.

Note: The plug severed from the mains lead must be
destroyed, as a plug with bared flexible cord is hazardous
if engaged in a live socket outlet.

SPECIAL INSTRUCTIONS FOR U.K. MODEL

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

FEATURES

SUPPLIED ACCESSORIES

• This subwoofer employs Advanced Yamaha Active
Servo Technology II, which Yamaha has developed for
the production of 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
audio 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 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.

• 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.

Non-skid pads

ATTACHING THE NON-

SKID PADS

To enjoy the high sound quality, stabilize the subwoofer
using the non-skid pads.

Attach the provided non-skid pads in the four corners of the
underside of the subwoofer to prevent the subwoofer from
moving as a result of vibration, etc.

PLACEMENT

One subwoofer will have a good effect on your audio

A

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

A

fig. .) If using two subwoofers, it is recommended to
place them on the outside of each front speaker. (See

B C

fig. .) The placement shown in fig. is also possible,
however, if the subwoofer is placed directly facing the
wall, the bass effect may suffer due to cancellation of direct
and reflected sounds. To prevent this from happening,
place the subwoofer at an angle, as in fig. or .

B

A

B

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 developed between two parallel walls and
cancel the bass sounds.

In such a case, place the subwoofer at an oblique angle
to the wall. It also may be necessary to break up the
parallel surfaces by placing bookshelves, etc. along the
walls.
