FEATURES

●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 Technology.) This super-bass sound adds a more realistic, theater-in- the-home effect to your stereo system.

●This subwoofer can be easily added 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 should be matched to the sounds of your main speakers. You can create the best sound quality for various listening conditions by using the HIGH CUT control and the PHASE switch.

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

●You can select bass effect suitable for the source by using the BASS switch.

QD-Bass Technology

QD-Bass (Quatre Dispersion Bass) technology uses square, pyramid-shaped reflective plates to radiate the sound in four horizontal directions.
