    An automatic electronic device that senses the onset of feedback, and cancels it before it gets out of hand. This is achieved by using a specialized equalizer with multiple, very narrow filter bands, positioned between the audio source and the speakers. The unit "searches" for the beginnings of feedback, analyzes the problem frequency and cuts that band. Good eliminators carry out this whole process in mere milliseconds, and can respond to the fact that feedback may occur at many different frequencies throughout a live performance.
