Hi all,
I have a Behringer B-5 condensor mic, long out of warranty, that has
developed a 'stomach rumbling/rolling thunder' sound behind the audio, which
peaks erratically every 5-10 seconds as a 'shorting/fizzing' sound that
drives the signal into the red. The audio itself is not distorted, but fails
to mask the rising background rumble. It does this no matter whether the
omni or cardioid capsule is fitted, in fact even does so when no capsule is
installed. Since I have little to lose by investigating the innards, what
components would you suggest I test or replace in a repair attempt....it's a
"cheap-end" mic after all !
Thanks,
Ray
Maybe junk on the diaphragm. Connect it, and exhale slowly into it. If it
sounds like a distant thunderstorm afterwards for a while, you have junk on
the diaphragm that's become conductive with or above a certain humidity
level.
Overly humid environment?
Drying the mic out with dessicants (sp?) in a sealed bag might be all you
need.
