Hi, betwixt and BigBoss,
Thanks for your reply.
I bought a Philip MIC, SHM1000, which I only know is capacitor MIC, and needs external power supply.
I used multi-meter to test it, and found MIC+ and MIC- is short, i.e. 0 ohm.
If using diode mode test, it is 0.4V and 1.2V vice versa.
SO I wonder:
1. If I can use post #1 circuit for SHM1000?
2. If I use 12V as power supply, what resistor should I series in?
Best,
Tony Liu

And Philip designed it for computer external MIC.

Its connector is 3.5mm, three sector. So it should be MIC+, MIC-, and GND.
