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.
