Feedback Eliminator

[BooBoo]

You can get a good feedback eliminator that will do the job it was intended for. The features to look for are finding one that will detect the spike in the narrowest band possible, then release it after a short amount of time. This does not take the place of EQing, but is a tool to use with it and can help provide a cleaner sound at a higher level.

Small loud rooms can be tough. One thing to do is to put sound absorption behind the stage and would do a better job than an eliminator. Many times the same sound can bounce off the fore wall then back to the back wall and into the mic in time to create the feedback. Something on the wall behind the mic can help blunt a return to the mic.

Neither will help when someone points a mic into a speaker..
