Here is the general scoop.
The mic actually has two different ground lines.
Therefore do not ground the mic case to the shield of a cable.
The three connections for the mic are ground, line, and power.
The line out wire has dc that needs isolation at the very least.
You have to build using quality rf shielding if you are going to run a
stereo pair. That means full cages, christmas trees, and short leads.
I will define the heart of the systems I have built and there is
nothing unique about the rest of the circuit other than what I stated
above. #3 and #4 are my recommended for 2 or more mics
1. silicon diode used as a 1/2 volt drop off of a 9 volt battery.
2. trim pot used as a 1/2 volt drop off a 9 volt battery.
3. LM317T IC off of 2 9 volt batteries.
4. 7808 IC off of 2 9 volt batteries.
5. dual pnp's used with p48 power.
