TROUBLESHOOTING
If there is no sound from any of the speakers: � Check that receiver/amplifier is on and a source is playing. � Check that the powered subwoofer is plugged in, and its Power switch ¡ is switched on to the ��� position. � 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. � 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 connections 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 configured 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 working correctly. Turn everything back on, and determine whether the problem is in the same place, i.e., the speaker that was working previously now has no sound and the speaker that was not working now sounds fine; or whether it has moved, i.e., the speaker that was not working still has no sound and the speaker that was working is still fine. If the problem is in the same place, 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 information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit our Web site at www.jbl.com for further information. If there is no sound from the center speaker: � Check all wires and connections between 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 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. 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. � Make sure the powered subwoofer is plugged in, and its Power switch ¡ is switched on to the ��� position.
� In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the subwoofer and LFE output are enabled.
