4.7 MIC Audio

PILOT MIC IN and COPILOT MIC IN are standard carbon or dynamic MIC inputs with integrated

preamps providing minimum 20 mVrms into a 150  AC load.

PILOT MIC IN and COPILOT MIC IN are set in the factory so that 150 mVrms modulates the transmitter

to 90% nominally at 1000 Hz. The microphone gain adjustment is made through Configuration Mode.
