Troubleshooting

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

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

•Powered subwoofer is plugged in and is either in the “On” or “Auto” position.

•Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, or punctured.

•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 con- nections 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 con- nections 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 imped- ance requirements of your receiver/amplifier.

If there is low bass output, check the following:

•Make sure the connections to the left and right “Speaker Inputs” have the correct polarity (+ and –).

•Make sure that the sub- woofer is plugged into an active electrical outlet.

•Powered subwoofer is plugged in and is either in the “On” or “Auto” position.

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

•Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are connected. 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 Dolby surround. If it is not, check to see if your receiver/amplifier has other surround modes you may use.
