B G R T

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 equipment. Never pull the wire itself.

5. Do not attempt to clean the unit with chemical solvents;

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 long periods of time

(i.e., 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 electrical storm.

9. Since this unit has a built-in power amplifier, heat will

radiate from the rear panel. Therefore, place the unit apart from the walls, allowing enough space above, behind and on the both sides of the unit to prevent fire and damage. Also, do not position with the rear panel facing down on the floor or other surface.

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

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 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.

13.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.

14. Voltage Selector (General and China Models only)

The voltage selector on the rear panel of this unit must be set for your local main voltage BEFORE plugging into the AC main supply. Voltages are AC 110/120/220/240V, 50/60 Hz.

IMPORTANT

Please record the serial number of this unit in the space below.

Serial No.: The serial number is located on the rear of the unit.

Retain this Owner’s Manual in a safe place for future reference.

15.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 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 THE 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 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.

WARNING

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

FEATURES

• This subwoofer system employs Advanced YAMAHA Active Servo Technology which YAMAHA has developed for reproducing higher quality super-bass sound. (Refer to page 10 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 unit can be added easily to your existing audio system by connecting to either the speaker terminals or the line output (pin jack) terminals of the amplifier.

PLACEMENT

One subwoofer will have a good effect on your audio system, however, the use of two subwoofers is recommended to obtain more presence.

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. To prevent this, face the subwoofer system obliquely to the wall as in fig. Å or ı.

Note

There may be a case that you cannot obtain enough superbass sounds from this unit when listening at the middle of the room. This is because “standing waves” have developed between two parallel walls and the bass sounds are canceled. In such a case, face the unit obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls.
