TROUBLESHOOTING
If there is no sound from any of the speakers:
•Check that receiver/ampli- fier is on and a source is playing.
•Check that the powered subwoofer is plugged in, and its Power switch å is switched on (“•” position).
•Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are con- nected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.
•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 con- nected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.
•In Dolby Digital or DTS modes, make sure that the receiver/processor is config- ured so that the speaker in question is enabled.
•Turn off all electronics
and switch the speaker in question with one of the other speakers that is work- ing correctly. Turn every- thing back on, and deter- mine whether the problem has followed the speaker, or has remained in the same channel. If the problem is in the same channel, the source of the problem
is most likely with your receiver or amplifier, and you should consult the
owner’s manual for that product for further informa- tion. If the problem has fol- lowed the speaker, consult your dealer for further assis- tance or, if that is not possi- ble, visit www.jbl.com.

•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 (or no) bass output:
•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
electrical outlet, and is turned on (Power switch å in the “•” position).
•In Dolby Digital or DTS modes, make sure your receiver/processor is config- ured so that the subwoofer and LFE output are enabled.
If there is no sound from the surround speakers:
•Check all wires and con- nections between receiver/ amplifier and speakers. Make sure all wires are con- nected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.
•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.
