DJ Alvyn K, Oli: I find it hard to believe that you can't make the distortion go away by talking at a lower volume or moving away from the microphone. At what point does the distortion go away?
Oli: I checked with our production staff. The mic circuits on all production units are identical. It's extremely unlikely that the mic circuits are defective because the same exact distortion happens on both mic channels. Anyways if you could provide details like Alvyn K that would be really helpful.
Alvyn K: So you have mic gain = MINI. Could you be more specific? For example 7:00 is off, 9:00 is very low gain with the stripe pointing to the left, etc. Then for the LEDs in the green so at which dB level do they peak? This will give me an idea of how much signal you are getting out of the microphone.
For the wireless microphone, can't you just reduce the gain on the receiver?
Anyways, the Beta 58A looks like a good candidate for testing due to it's extremely high output compared to other microphones.
