Active Servo Technology II which Yamaha has

sound. (Refer to page 14 for details on Advanced
Yamaha Active Servo Technology II.) This super-bass

audio system by connecting to either the speaker
terminals or the line output (pin jack) terminals of the

super-bass sound should be matched to the sounds of
your front speakers. You can create the best sound
quality for various listening conditions by using the
HIGH CUT control and the PHASE switch.

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.
