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.

Thank you for selecting this YAMAHA Subwoofer System.
CAUTION: Read this before operating your 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 something drops into the set, contact your dealer.
●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 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 enough spaces 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.
<For U.K. and Europe models only>
Be sure to allow spaces of at least 20 cm above, behind and on both sides of the unit.
●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 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
(China and General models only) 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.
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 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.
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 on the rear panel 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.
