Hi there
I've bought this lot of SubZero branded OEM microphones dirt cheap (haven't received them yet) and looking for inspiration for potential builds/mods.
Any sugesttions for pcbs that fit the LDC?
What to do with the SDC's?
You could try one of the PCBs we did for the RF mic project ? -- DIY RF Condenser Microphone
Might be interesting to compare it with the second LDC mic you've shown.
Same capsule, same housing -- it's just one mic would have a DC bias, the other RF. See how thy compare?.....
