Andrew--
Those are both high serial numbers. You have symmetry with the two
mics so you can easily locate the source of the buzz.
Once the problem is happening, note which channel it is in and record
some of the noise. Jiggle both mic cables to see if the buzz changes
in volume or cuts in and out. If not, flip the mic cables-- that is--
connect the mic cable going to the right mic to the left mic and the
cable going to left mic to the right mic. If the problem is now
heard in the other input channel, the mic with the buzz/noise is bad.
Contact the dealer. They should replace it.
By "hot shower," in my previous post I should have elaborated, "place
the mics in a closed room with a hot shower running."
Let us know what materializes.
