[. . . ] CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes, or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. The customer is responsible for proper installation and proper selection of hardware. CENTER Receiver Speaker Outputs Speakers and electronics terminals have corresponding (+) and (­) terminals. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and poor imaging. To use the binding-post speaker terminals, unscrew the colored collar until the pass-through hole in the center post is visible. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. High Frequency ­ + ­ + Low Frequency ­ + Amplifier Bi-Wire Connections TROUBLESHOOTING If there is no sound from any of the speakers: If the system plays at low volumes but shuts off as volume is increased: If there is no sound from the surround speakers: · Check that receiver/amplifier is on and that a source is playing. · Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: · Check all wires and connections between receiver/ amplifier and speakers. · Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.

Make sure none of the speaker wires are frayed, cut or punctured. · Review proper operation of your receiver/amplifier and its surround sound features. · Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/ amplifier has other surround modes you may use. · In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the surround speakers are enabled. · Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD player's menu and the DVD disc's menu. · Check the "Balance" control on your receiver/ amplifier. · Check all wires and connections between receiver/ amplifier and speakers. · Make sure no wires are touching other wires or terminals and creating a short circuit. · Make sure all wires are connected.
