25、th Canadian ICES-003.CONTENTS122 En This subwoofer system employs Advanced Yamaha Active Servo Technology II,which Yamaha has developed for the production of higher quality,super-bass sound.(Refer to page 14 for details on Advanced Yamaha Active Servo Technology II.)This super-bass sound adds a more
26、 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 effective use of the subwoofer,the subwoofers super-bass sound should
27、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.The Automatic power-switching function saves you the trouble of pressing the STANDBY/ON button to turn the power on and off.You ca
28、n select a bass effect suitable for the source by using the B.A.S.S.button.This subwoofer system is equipped with a linear port unique to Yamaha that provides smooth bass response during playback,minimizing extraneous noise not included in the original input signal.After unpacking,check that the fol
29、lowing parts are contained.To enjoy the high sound quality,stabilize the subwoofer using the non-skid pads.Attach the provided non-skid pads in the four corners of the underside of the subwoofer to prevent the subwoofer from moving as a result of vibration,etc.FEATURESQD-Bass TechnologyQD-Bass(Quatr

31、 to obtain more effect.If using one subwoofer,it is recommended to place it on the outside of either the right or the left front speaker.(See fig.)If using two subwoofers,it is recommended to place them on the outside of each front speaker.(See fig.)The placement shown in fig.is also possible,howeve
32、r,if the subwoofer system is placed directly facing the wall,the bass effect may suffer due to cancellation of direct and reflected sounds.To prevent this from happening,place the subwoofer system at an angle,as in fig.or.NoteThere may be a case that you cannot obtain enough super-bass sounds from t
