User's Manual

microphone should be given time to reach
room temperature, and as a rule it will then
perform flawlessly.
– Sometimes dirt can get into the contacts
where the capsules are attached; this, too,
can cause impulse noise. You can clean the
contacts yourself by using compressed air
(without lubricant) from an aerosol can. If
that doesn't help, you can scrub them with
a new, clean toothbrush dipped in isopropyl
alcohol, holding the microphone so that
the contacts face downward. Shake off any
extra fluid; under no circumstances can it
be allowed to flow into the amplifier! Be
careful to wipe the contacts dry.
If this treatment does not eliminate the noise,
it is possible that dirt has gotten inside the
capsule itself – in which case the capsule must
be sent back to the factory for cleaning. We
strongly urge customers not to open a capsule
or attempt to clean it themselves. Doing so
would also void all warranties. Neither should
the contact rings of a capsule be cleaned with
any kind of liquid. Windscreens are recom-
mended when micro phones have to be used
in dirty or dusty environments in order to
avoid problems of the kind described above.
