Precautions: Read this before operating this unit

 

• 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 any foreign objects drop 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 of 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 equipments.  
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 by vibrations and breaks, it may 
cause bodily injury. 

A burning candle etc.

If the candle falls by vibrations, it may cause fire and 
bodily injury.

A vessel with water in it 

If the vessel falls by vibrations and water spills, it 
may cause damage to the speaker, and/or you may get 
an electric shock.

 

• VOLTAGE SELECTOR 

(For China, Korea 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.

 

• 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 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 by 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 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 subwoofer 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 the subwoofer.

WARNING

 

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