We Want You Listening For A Lifetime

YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out
of your equipment by playing it at a safe level. One that lets
the sound come through loud and clear without annoying
blaring or distortion – and, most importantly, without
affecting your sensitive hearing.

Since hearing damage from loud sounds is
often undetectable until it is too late, YAMAHA
and the Electronic Industries Association’s
Consumer Electronics Group recommend you
to avoid prolonged exposure from excessive
volume levels.

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
apparatus may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
The wire which is coloured BLUE must be connected to
the terminal which is marked with the letter N or coloured
BLACK. The wire which is coloured BROWN must be
connected to the terminal which is marked with the letter L
or coloured RED. Making sure that neither core is
connected to the earth terminal of the three pin plug.

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.

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 (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 spaces of at least 20 cm 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 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
that the unit is faulty.

● 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.

● VOLTAGE SELECTOR

(For China, Korean and General models)
The voltage selector switch on the rear panel of this
unit must be set for your local
main voltage BEFORE plugging
this unit into the AC main supply.
Voltages are 110-120/220-240 V AC,
50/60 Hz.

Standby mode
If the POWER switch is set to the ON position and the
AUTO STANDBY switch is set to the HIGH or LOW
position, this unit turns into the standby mode when no
signal is received by this unit for 7 to 8 minutes.
In this state, this unit is designed to consume a very
small quantity of power.

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.

CAUTION: Read this before operating your unit.

Thank you for selecting this YAMAHA Subwoofer System.
