FEATURES
● This subwoofer system employs Advanced Yamaha
Active Servo Technology which YAMAHA has developed
for reproducing higher quality super-bass sound. (Refer to
page 9 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.
● 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 switch.
● The Automatic power-switching function saves you the
trouble of pressing the STANDBY/ON button to turn the
power on or turn it to the STANDBY mode.
● You can select bass effect suitable for the source by
using the B.A.S.S. button.
QD-Bass Technology
QD-Bass (Quatre Dispersion Bass) technology uses
square, pyramid-shaped reflective plates to radiate the
sound in four horizontal directions.
