I have purchased two B-2 pro mics over the last few years. Initially the sound awesome, clear, and very low noise. After about 2 months of use they have extreme noise and low output. The mics are left powered and go into a 100W transmitter at my radio station. I have since switched to a EV RE20 which is indistructable but requires the preamps to be mazed out. I gave one of the broken B-2 Pros away, but would like to fix the one I still have. I have seen this issue elsewhere on the internet and it appears to be a design flaw. Does anyone have the schematics or know what the common mode of failure on this mic is? I would prefer not to have to reverse engineer the mic.

Hello,
my freshly bought TM1 condenser mic works only for 1-3 seconds, then dropping power and signal.
Bought additional pre-amp for mic, set gain at 100%, then I got the weak level on audio interface, but signal was more noise, then voice itself.
Changed cables, phantom power suppliers etc. So definitelly broken unit and no news from support/service :(
I will have to sign very closely to mic because sound is really low, and when I plug mic from my laptop then I am not able to use my head phones at the same time.
