No Output
• Check that all your system components are turned on.
• Check the status LED. It should be green. Please see the
Controls section of manual.
• Check your speaker wires and connections.
• Check all interconnecting cables.
• Try hooking up a different set of speakers. The lack of
output could point to a problem with other equipment in
your system (amp, pre-amp, processor, etc.)
• If the problem only occurs in one speaker, try swapping
the speaker locations and see if the problem follows. If
the problem moves with the speaker, the problem may
be with the speaker itself. If the problem stays in the same
place this 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?
• Check the status LED. It should be blue. Please see the
Top Panel Controls section of manual.
• Dirt and dust may need to be vacuumed off. Please see
the FAQ regarding vacuuming.
• If using a single-wire connection, check to make sure that
the jumper clips are in place and that the binding posts
are firmly hand-tightened.
• Check the binding posts. Are they dirty? If so clean them
with rubbing alcohol.
• Check the binding posts. Are they 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 and may require new elec-
trostatic panels.
Popping and Ticking Sounds, Funny Noises
• These occasional noises are harmless and will not hurt
your audio system or your speakers. 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.
Exaggerated Highs, Brightness
• Check the toe-in of the speakers. Read the Placement
section of this manual for more information.
Muddy Bass
• Check placement. Try moving the speakers closer to the
front and sidewalls.
• Check the type of feet that are being used. Try attaching
the coupling spikes.
• 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 status LED. It should be blue. Please see the
Top Panel Controls section of manual.
• Check your low bass output and distance jumpers on the
speaker’s top control panel. Are they inserted all of the
way? Are they installed in one of the listed configurations?
• Check the binding posts. Are they dirty? If so clean them
with rubbing alcohol.
• Check the binding posts. Are they loose? Make sure they
are firmly hand-tightened.
Poor Imaging
• Check placement. Are both speakers the same distance
from the walls? Do they have the same amount of toe-
in? Try moving the speakers away from the back wall and
side walls.
• Check the polarity of the speaker wires. Are they con-
nected properly?
• Try switching the left speaker with the right.
• 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.
