 **Microphone:** The Microphone signal is a typical electret microphone signal: -45dBV +/- 3dbV into 600 to 1k ohm.  The Radio device provides a DC bias voltage to power the microphone element, about 0.5mA across a 2vDC microphone element (eg: 5vDC through 6.8k ohm resistor).  Dynamic microphone elements require about 10 to 15db of amplification, and for the DC bias to be blocked; this Standard provides a simple 5 component microphone pre-amp, powered by the DC bias, to bring a Dynamic microphone element up to Electret signal levels.
