Why does my Electro-Voice EVOLVE30M-US Speakers microphone produce acoustic feedback?
- KKimberly JensenAug 8, 2025
Acoustic feedback in Electro-Voice Speakers when the microphone input level is amplified is typically due to incorrect gain structure, the MODE setting, or microphone placement. To resolve this, reduce the microphone signal by lowering the INPUT level. Positioning the microphone closer to the sound source can increase gain before feedback. Also, check the MODE setting and change it to LIVE or SPEECH instead of MUSIC. Finally, adjust the loudspeaker setup so that the microphone is positioned behind them whenever possible. If using a separate loudspeaker in a monitor position, aim the loudspeaker towards the back of the microphone.
