English Thank you for selecting this YAMAHA subwoofer system. CAUTION: Read this before operating your unit. ● To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference. ● If you hear distorted noise (i.e., unnatural, intermittent “rapping” or “hammering” sounds) coming from this unit, reduce the volume level.
FEATURES ● This subwoofer system employs Advanced YAMAHA Active Servo Technology which YAMAHA has developed for reproducing higher quality super-bass sound. (Refer to page 12 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. ● 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.
Å ( ı : subwoofer, Ç English PLACEMENT : 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 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. ● Basically, connect the subwoofer to the line output (pin jack) terminal(s) of the amplifier. (Refer to pages 4 and 5 for details.

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. This function will operate by sensing a certain level of low frequency input signal.
ADJUSTING THE SUBWOOFER BEFORE USE 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.

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.
