We Want You Listening For A Lifetime (for US customers only)
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.

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 (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.
14.Voltage Selector (General Model 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.
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.
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.
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
•This subwoofer system employs YAMAHA Active Servo Technology which YAMAHA developed for reproducing higher quality super-bass sound. (Refer to page 15 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.
•The use of the H.P.F. OUTPUT terminals for connecting with the amplifier is effective for improving sound quality of your speaker system.
This connection prevents sound output from the main speakers from muddying by filtering out low frequencies of input signals to be sent to the main speakers which are not suitable for reproducing low frequencies.
•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.
•A newly employed AUTO POWER ON/OFF switch saves you the trouble of pressing the POWER switch when turning the power on and off.
PLACEMENT |
|
|
|
A |
|
B |
C |
( |
: 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.
A .) If using two subwoofers, it is recommended to place them on the outside of each main speaker. (See fig. B .) The placement shown in fig. C 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. A 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.
