This is how sensitive the microphone pick up is and this is adjusted on the handheld microphone, bodypack or SKP transmitter itself. ... If the microphone is too sensitive the input will overload the microphone and the AF level will peak and the audio will be clipped.
To avoid microphone interference, make sure the microphone is at a low level and that it is a good distance from your amp and speakers. Beginner performers and DJs often face this common issue with their wireless microphones.
