[sudo-discuss] balanced electret microphone circuit

* i made a microphone out out of an electret mic capsule that matt found in sudo w/the following circuit:* * 10u +---------o-------------||------o----------------- HOT (2) | | | | |- | | CAPSULE 22k | |+ | | | 10u | | o-------------||------|------o---------- COLD (3) 2k2 | | | | 2k2 | 22k | | | | | o--330R---o----o------o------+ | +| +| |+ | 10u 12V 10u | -| -| |- --o---------o---------o----o------------------------ GROUND (1) * *and it works well! very responsive* *-it must have phantom power (48V from mixer/mic preamp)* *-"12V" in the diagram is a 12v zener diode* *- 10u in the diagram are plastic film caps. (if you only have 10uF electrolytic caps also use 100nF in parallel, like i did))* *source <http://www.epanorama.net/circuits/microphone_powering.html>*
