Positioning the subwoofer Although the placement of the subwoofer is not as critical as that of the other speakers, it is best to place the subwoofer outside either the right or left front speaker as shown in figure A. A (Recommended) : Subwoofer : Front speaker The placement shown in Figure B is also acceptable. However, in some cases, if you listen from the center of the room, the super-bass range from the subwoofer may sound weak.
Connections Caution: Plug the power cables for the subwoofer and other audio/video components into an AC outlet only after you complete all other connections. Basic connection example Connect a subwoofer cable to the output jack of your AV amplifier and to the INPUT jack of the subwoofer. Connecting components and the subwoofer to AC power After you complete a subwoofer connection, plug the amplifier, other audio/video component, and the subwoofer into an AC outlet of appropriate voltage.

Advanced Yamaha Active Servo Technology The theory behind Yamaha Active Servo Technology is based on two 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 if the unit does not function properly. If the problem you are experiencing is not listed, or if the instructions fail to help you resolve the problem, disconnect the power cord and contact your authorized Yamaha dealer or service center. Problem Cause Remedy Power is not supplied even though the POWER switch is set to the ON position. The power plug is not securely connected.
