What to do if my Electro-Voice Speaker System microphone produces acoustic feedback when the input level is amplified?

If your microphone produces acoustic feedback when the input level is amplified, it may be due to an incorrect gain structure. Reduce the microphone levels at the mixing console or input source. If the microphone is connected directly to the speaker, reduce the input level on the speaker. Positioning the microphone close to the sound source increases gain-before-feedback. If the MODE is set to MUSIC, change it to LIVE or SPEECH. Also, position the loudspeakers so the microphone is behind them whenever possible. If using the loudspeaker in a monitor position, aim the loudspeaker to the back of the microphone.
