TROUBLESHOOTING

If there is no sound from any of the speakers:

Check that receiver/amplifier is on and a source is playing.

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 “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.

In Dolby Digital or DTS modes, make sure that the receiver/processor is con- figured so that the speaker in question is enabled.

If there is no sound from the center speaker:

Check all wires and connec- tions between the receiver/ amplifier and speaker. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.

If your receiver/processor is set in Dolby Pro Logic® mode, make sure the center speaker is not in phantom mode.

If your receiver/processor is set in Dolby Digital or DTS mode, make sure the receiver/ processor is configured so that the center speaker is enabled.

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

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 impedance requirements of your receiver/amplifier.

If there is low (or no) bass output

(1500 Array):

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

Make sure the subwoofer

is plugged into an active elec- trical outlet.

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.
