23.16.5 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 Ω 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.
