Today's Lesson
The first key to managing and eliminating feedback on a live stage is to understand how feedback is created.
Feedback is the result of a sound looping between an input and an output. More specifically, feedback occurs when a sound is picked up by a microphone, then amplified through a loudspeaker, and then that amplified sound is picked up again by the same microphone re-amplified over and over again, creating an endless loop. The result of this loop is that really annoying, sometimes ear piercing ring or screech. That’s it, that’s all that’s happening.
In order to eliminate feedback all we have to do is break that loop. In the case of a live stage, this is not always as easy as it sounds.
