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. • Basically, connect the subwoofer to the line output (pin jack) terminal(s) of the amplifier. (Refer to pages 4 and 5 for details.

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.
TROUBLESHOOTING Refer to the chart below when this unit does not function properly.
