20 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
• Possibly means low electrostatic panel output. See
'Weak Output from Electrostatic Panel, Loss of Highs’.
Lack of Bass, No Bass
• Check your speaker wires. Is the polarity correct?
• 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.
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.
