WebElectronic Dynamic Bias System EBS-1 or HF Amplifier auto-bias theory. The idea behind automatic electronic bias is a reduction of quiescent current and heat in high power radio-frequency amplifiers. The basic idea is when RF drops to a very low level, large amounts of quiescent current are not necessary. WebBias is a dc voltage (1.5 - 9 volts typically) that is provided on a single conductor. Unlike phantom power, bias does not require a balanced circuit. Bias supplies power to a Junction Field Effect Transistor (JFET) connected to the output of an electret condenser mic element.
