Connection Tips

Speakers and electronics terminals have corresponding (+) and

(–)terminals. It is important to connect both speakers identi- cally: (+) 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 a poor stereo image.

Troubleshooting

If there is no sound from any of the speakers, check the following:

•Receiver/amplifier is on and a source is playing.

•Review proper operation of your receiver/amplifier.

If there is no sound coming from one speaker, check the following:

•Check the “Balance” control on your receiver/amplifier.

•Check all wires and connec- tions between receiver/ amplifier and speakers.

•Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.

If the system plays at low volumes but shuts off as volume is increased, check the following:

•Check all wires and connec- tions between receiver/ amplifier and speakers.

•Make sure all wires are con- nected. 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 imped- ance requirements of your receiver/amplifier.

If there is low bass output, check the following:

•Make sure the polarities (+ and –) of the left and right “Speaker Inputs” are connected properly.

If there is no sound from the center speaker, check the following:

•Make sure that your receiver’s Center Channel Mode is in the ”normal“ or ”wide“ position. If it is in the ”phantom“ position, the center speaker will not play.

•Check all connections between processor/amplifier and the center speaker.
