PLACEMENT Å ( ı : subwoofer, Ç : main speaker) One subwoofer will have a good effect on your audio system, however, the use of two subwoofers is recommended to obtain more effect. If using one subwoofer, it is recommended to place it on the outside of either the right or the left main speaker. (See fig. Å.) If using two subwoofers, it is recommended to place them on the outside of each main speaker. (See fig. ı.) The placement shown in fig.
CONNECTIONS Caution: Plug in the subwoofer and other audio/video components after all connections are completed. ● All connections must be correct, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also refer to the owner’s manual for each of your components. ● The subwoofer can be connected to either the line output (pin jack) terminals or the speaker output terminals of the amplifier. Choose one of the ways shown in this section that is more suitable for your audio system.

Connecting to H.P.F. OUTPUT terminals The use of the H.P.F. OUTPUT terminals for connections with the amplifier will improve sound quality of your speaker system. The H.P.F. (High-Pass Filter) OUTPUT terminals of the subwoofer cut off frequencies below the selected frequency point from the input signals, and output high frequencies only. By connecting this terminal with the MAIN IN terminals of the amplifier, the main speakers reproduce high frequencies only.

English Connecting the AC power cable POWER ON OFF AC IN When all connections are completed, plug the included power cable into the AC IN socket of the subwoofer, and then plug in the power cable to the wall outlet. (U.S.A. model) To AC outlet Notes ● Never connect any power cable other than the included one to the subwoofer. Otherwise, it may result in causing fire or an electrical shock.

AUTOMATIC POWER-SWITCHING FUNCTION If the source being played is stopped and the input signal is cut off for 7 to 8 minutes, the subwoofer automatically switches to the standby mode. (When the subwoofer switches to the standby mode by the automatic powerswitching function, the power indicator lights up in red.) When you play a source again, the power of the subwoofer turns on automatically by sensing audio signals input to the subwoofer.
Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures described below. 3 8 7 SUBWOOFER SYSTEM YST-SW1500 SUBWOOFER SYSTEM YST-SW1500 MUSIC/MOVIE STANDBY/ON B.A.S.S.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY The theory of Yamaha Active Servo Technology has been based upon two major factors, the Helmholtz resonator and negative-impedance drive. Active Servo Processing speakers reproduce the bass frequencies through an “air woofer”, which is a port or opening in the speaker’s cabinet. This opening is used instead of, and performs the functions of, a woofer in a conventionally designed speaker system.
