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.
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.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
CAUTION (FOR CANADA MODEL)
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT AND FULLY INSERT.
FOR CANADIAN CUSTOMER
THIS CLASS B DIGITAL APPARATUS MEETS ALL REQUIREMENTS OF THE CANADIAN INTERFERENCE-CAUSING EQUIPMENT REGULATIONS.
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 apart from the walls, allowing a space of at least 20 cm (7-7/8”) above, behind and on the both sides of the unit. 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.As this speaker contains strong magnet, avoid placing watches,
magnetic tapes, etc. near this unit. Also, placing the speaker near a TV set may impair picture color. If this happens, move the TV set away from the speaker.
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.
13.This unit has a port called “air woofer” which is for reproducing a
super-bass sound. Be careful not to put a hand or some objects into the port, otherwise it may give you an electric shock or give this unit a damage, or cause a fire.
The apparatus is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the apparatus itself is turned off.

FEATURES

A
B
C
English
This subwoofer system employs YAMAHA Active Servo
Technology which YAMAHA developed for reproducing higher quality super-bass sound. (Refer to page 12 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.

PLACEMENT

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. A newly employed AUTO POWER ON/OFF switch saves
you the trouble of pressing the POWER switch when turning the power on and off.
( : subwoofer, : main speaker)
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
A
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
.
B
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.

Put the provided rubber pads at the four corners on the bottom of this unit to prevent this unit moving due to vibrations etc.
