Microphone bias is a voltage used to power the Junction Field Effect Transistor (JFET) often integrated into an electret condenser microphone capsule. JFETs present the electret conderser with a relatively high input impedance. This reduces signal loss and helps present a low source impedance to the microphone preamp. 2 Anonymous · June 18, 2020

Mic Bias is 1.5V-3V applied to the electret element to make the internal pre-amp work. On some mics, this is provided by a watch battery and professional mics use 12-48V "Phantom" power supplied through the hot and cold balanced line. Most laptops and lots of hand held recorders will also supply the bias through a stereo mini-jack connector.

13.8k. 725. Posted June 7, 2019. In general front panel audio connectors are not great, because the wires have to travel all the way from the bottom corner of the motherboard (typically) over the motherboard and go diagonally towards the top of the case... so it's a lot of distance where analogue signals travel through basically unshielded wires.
