Waist-mounted wireless microphones generally use miniature electret condenser microphones, which are highly sensitive and omnidirectional, and are easy to generate acoustic feedback when used, especially in the case of using a returning speaker on the stage. For drama and essays, if the stage is the floor and the underside of the floor is a cavity, in order to prevent low-frequency resonance, the bass gain of the channel on the mixer should be properly attenuated, and the signal of the system will be returned. The output gain is also subjected to the necessary attenuation. The general attenuation is above 6dB. In case of a passionate performance, the signal output of the feedback system can be removed to avoid acoustic feedback.
