FEATURES

●This subwoofer system employs Advanced YAMAHA Active Servo Technology which YAMAHA has developed for reproducing higher quality super-bass sound. (Refer to page 18 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 the subwoofer, the subwoofer’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 button.

●You can make setting changes and adjustments for the subwoofer by using the remote control without moving from your listening position.

●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 B.A.S.S. button.

●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.

QD-Bass Technology

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