MartinLogan Purity Fully Powered Hybrid Electrostatic Loudspeaker - Manual (Page 21)

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 set of speakers. 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 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.
• 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 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 and
sidewalls.
• 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.
