26、ater-in-the-home effect to your audio 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 be matched to t
27、he 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.This subwoofer system
28、 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 following parts are contained.To enjoy the high sound quality,stabilize the subwoofer using the non

31、)The placement shown in fig.is also possible,however,if the subwoofer 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 at an angle,as in fig.or.NoteThere may be a case that you cannot o
32、btain enough super-bass sounds from the subwoofer when listening in the center of the room.This is because“standing waves”have developed between two parallel walls and cancel the bass sounds.In such a case,place the subwoofer at an oblique angle to the wall.It also may be necessary to break up the p
