Mic Sensitivity Calibration

This procedure allows you to calibrate the microphone sensitivity level at each CPS setting
(-12, -9, .... +9, +12), eliminating tolerances and deviations in the microphone hardware lineup
circuitry. By tuning each CPS setting, the microphone sensitivity will be adjusted to exactly 3 dB
difference between every 2 consecutive settings throughout the programmable range of the circuit.
The Autotune All button will calibrate all nine settings in one adjustment.
