CHAPTER 9 – TROUBLESHOOTING AND SERVICE GUIDE

Project K2 S5800 loudspeakers are designed to provide years of trouble-free service.

If you are experiencing difficul- ties, we suggest you check these possibilities before contacting your Project K2 specialist dealer for assistance.

IF THERE IS NO SOUND FROM ANY OF THE SPEAKERS:

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

•Check all wires and connections between the receiver/amplifier and the speakers. Make sure all wires are connected, and are not frayed, cut or punctured. No wires or strands should be touching each other or the shorting bars connected to other terminals.

•Review proper operation of your receiver/amplifier.

IF THERE IS NO SOUND COMING FROM ONE SPEAKER:

•Check the “Balance” control on your receiver/processor.

•Check all wires and connections between the receiver/amplifier and the speakers. Make sure all wires are connected, and are not frayed, cut or punctured. No wires or strands should be touching each other or the shorting bars con- nected to other terminals.

•In digital surround sound modes, make sure that the receiver/ processor is configured so that the speaker in question is enabled.

•Switch the speaker wires between the speaker with the problem and one that is working correctly. If the problem remains in the same speaker, then the fault is in the loudspeaker. In this event, consult your Project K2 S5800 specialist dealer for assistance. If, however, the problem has moved to the other speaker, then the cause is in either a cable or an electronic component.

IF THE SYSTEM PLAYS AT LOW VOLUMES BUT SHUTS OFF AS VOLUME IS INCREASED:

•Check all wires and connections between the receiver/amplifier and the speakers. Make sure all wires are connected, and are not frayed, cut or punctured. No wires or strands should be touching each other or the shorting bars con- nected to other terminals.

•If more than one pair of main speakers is being used, check the minimum impedance require- ments of your receiver/amplifier.

IF THERE IS LOW (OR NO) BASS OUTPUT:

•Make sure the connections to the left and right speaker termi- nals have the correct polarity.

•In digital surround modes, consider adding a powered subwoofer to play the LFE (low- frequency effects) channel of the program.

IF THE SPEAKERS SOUND QUALITATIVELY DIFFERENT IN AN INDEFINABLE WAY:

•Test the batteries and replace them if necessary.

NOTE: The batteries should be tested once a year in any event.
