FEATURES

English

•This subwoofer system employs Advanced YAMAHA Active Servo Technology which YAMAHA has developed for reproducing higher quality super-bass sound. (Refer to page 12 for details on Advanced YAMAHA Active Servo Technol- ogy.) 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.

•For the effective use of this unit, this unit’s super-bass sound must be matched to the sounds of your main speak- ers. You can create the best sound quality for various listening conditions by using the HIGH CUT control.

•The Automatic Standby function saves you the trouble of pressing the STANDBY/ON button to turn the power on and off.

PLACEMENT

ÅıÇ

(

 

: subwoofer,

: main speaker)

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 super- bass 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.

Use the rubber pads

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