Microphone Distortion Control

CPS Audio Settings. Microphone Distortion Control is the 2nd one down.

With Microphone Distortion Control the radio adjusts its microphone to match the users voice, so the transmission is never distorted.

This is a transmit-only feature. It improves voice quality when the user is speaking loudly into the microphone, and works alongside the standard AGC (Automatic Gain Control) of the radio. The radio continuously monitors the quality of the speech data as it is being processed. When it detects early signs of audio distortion, perhaps by someone speaking loudly over background noise, the radio reduces the sensitivity of the microphone until the distortion disappears.

Microphone Distortion Control is a natural extension of the Automatic Gain Control (AGC) feature, as it monitors and controls distortion of the transmit audio. The benefit of this feature will be most obvious in loud environments where the microphone input levels are much higher than the nominal input levels.

This feature was introduced in software release R02.20.00.

This feature is supported in Digital mode only.
