In the middle of the night, when I was recording the last track for the ending credit of the movie KURSInya, my mic started to introduce a very annoying constant clicking noise. It was rather loud and occurs approximately every half second.
Tinkering with the cable connections did not help, so I decided to open the microphone. Due to its weird construction (it is a cheap dynamic microphone) I had to cut the cables to take out the mic out of its casing. I found that wiring the mic ground connection into a large, electrically isolated body reduces the noise. So I proceeded and finished the recording session.
However, the problem persists. The noise is reduced, but never fall to zero. The worst thing about it is I cannot put the mic back into its casing (I still cannot find a way to open it). So it is now hanging, naked on the stand.
Today I found that unplugging my USB printer from the computer eliminates the noise completely ...
