Feedback Elimination

Eliminate feedback before it can happen. Learn how professional audio engineers eliminate feedback from the audio system before any artist walks in the door.

Identifying the room modes and free air resonance frequencies of a performance space and eliminating them before sound-check is the only way to assure that acoustic feedback cannot happen during a performance. There are straightforward methods that do not involve machinery or analysis by anything but your ears and brain. However, there are many useful devices for pinpointing troublesome frequencies, nodes and anti-nodes, and other wave phenomena that can severely affect your mix. We will examine both approaches in this class.
