TROUBLESHOOTING 7

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

• 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.

• 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.

• In Dolby Digital or DTS mode, check the speaker and channel output levels and adjust if needed.
• 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.harmankardon.com for further information.

• 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.

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

• Consider adding a powered subwoofer to your system.

• 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 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 if 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.
