I asked about this in another unrelated thread but got no replies. Hoping someone could shed some light on it. Electret mics are really compound devices, they're the actual microphone element and a simple Jfet amplifier stage. The - lead gets grounded and the + lead gets fed a couple of volts through a resistor and the signal is drawn off after the resistor. This makes it a polar device, thing is no matter which way I hook them up to my sound cards mic in jack they work. The ground is normal and the tip is getting a pinch over 2 volts. I'm just trying to understand how it works regardless of polarity?
