TROUBLESHOOTING

No Output

Check that all your system components are turned on.

Check your speaker wires and connections.

Check all interconnecting cables.

Try hooking up a different speaker. The lack of output could point to a problem with other equipment in your system (amp, pre-amp, processor, etc.)

Weak or no Output from Electrostatic Panel, Loss of Highs

Check the power cord. Is it properly connected to the speaker and to the wall?

Is the power cord connected to a switched outlet?

Dirt and dust may need to be vacuumed off. Please see the FAQ regarding vacuuming.

Check the binding posts. Are the dirty? If so clean them with rubbing alcohol.

Check the binding posts. Are the loose? Make sure they are firmly hand-tightened.

Has a foreign substance (such as a household cleaning chemical or soap) been applied to the panel? If so the speaker will require servicing.

Popping and Ticking Sounds, Funny Noises

These occasional noises are harmless and will not hurt your audio system or your speaker. All electrostatic speakers are guilty of making odd noises at one time or another. It is the result of airborne contaminates (most notably dust). Vacuuming is recommended.

These noises may be caused by dirt and dust particles collecting on the speaker, by high humidity.

Dirt and dust may need to be vacuumed off. Please see the FAQ regarding vacuuming.

Muddy Bass

Lack of Bass, No Bass

Check your speaker wires. Is the polarity correct?

Poor Imaging

Check the polarity of the speaker wires. Are they con- nected properly?

Are your speakers set up in an L-shaped room? If so, you may experience off-center imaging. Talk to your dealer about acoustical room treatment options.
