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. SPECIFICATIONS . 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. Type ...............

PLACEMENT A . English ( : subwoofer, : main speaker) It is recommended to place the subwoofer on the outside of either the right or the left main speaker. (See fig. A .) The placement shown in fig. . is also possible, however, if the subwoofer system is placed directly facing the wall, the bass effect may die because the sound from it and the sound reflected by the wall may cancel out each other. To prevent this from happening, face the subwoofer system at an angle as shown in fig. A. Note There may be a case that you cannot obtain enough super- bass sounds from the subwoofer when listening in the center of the room. This is because “standing waves” have been developed between two parallel walls and they cancel the bass sounds. In such a case, face the subwoofer obliquely to the wall. It also may be necessary to break up the parallel surfaces by placing bookshelves etc. along the walls. Use the non-skid pads Put the provided non-skid pads at the four corners on the bottom of the subwoofer to prevent the subwoofer from moving by vibrations etc. SUBWOOFER SYSTEM YST-SW015STANDBY/ON B.A.S.S.
