CAUTION: READ THIS BEFORE OPERATING YOUR UNIT

SAFETY INSTRUCTIONS

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

(ie., 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 at least 10 cm (4 inches) away from the wall. Also, do not position with the rear panel facing down on the floor or other surface.

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 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.

12 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.

FCC INFORMATION

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.

•

This subwoofer system employs YAMAHA Active Servo Technology which YAMAHA developed for reproducing higher quality super-bass sound. (Refer to page 11 for details on Active Servo Technology.) This unit does not only enhance bass frequency response of sound output in your audio system, but, by reproducing the bass frequencies, the subwoofer permits your existing amplifier and speakers to operate under less strenuous conditions, improving overall system performance.

•

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.

•

For the effective use of this unit, this unit’s super-bass sound must be matched to the sounds of your main speakers. Therefore, this unit employs a continuously variable high frequency cut-off point (HIGH CUT) control. Moreover, the PHASE switch allows you to select the best sound quality for various listening conditions.

If using one subwoofer, it is recommended to place it on the outside of either the right or the left main speaker. (See fig.

.) If using two subwoofers, it is recommended to place them on the outside of each main speaker. (See fig. .) The placement shown in fig. 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 shown in fig. or

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

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 being 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.
