• 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 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 B.A.S.S. button.
