Plugging and unplugging a microphone to make it work..

[antocu]

Hi guys, I've just build a Schoeps-style microphone with a LDC capsule.
It works and all voltage measures are correct. The thing is when I plug it into my interface and turn on phantom power I have bad S/N ratio, but if I unplug it and plug it back again then it works as it should, silent and sensitive. Has anybody ever had this experience? The circuit follows the original CMC5 schematics, I've just added xlr caps to filter RF noise

Seems it worked! Even if they weren't particularly dirty, maybe some dust. Thanks!
