Getting Rid of Feedback

What is feedback
Feedback is the nemesis of live sound engineers and performers and can ruin a live sound performance and send an audience running. Audio feedback occurs when the signal entering a mic that is also connected to a PA system feeds back on itself, causing a rapid increase in the volume that often ends with damaged amplifiers and blown speakers. If a mic is connected to a PA system and is near to the loudspeakers where the sound is coming out, then as the volume is turned up feedback can start to occur. This is because at some point the mic will not only be picking up the direct sound going into it but also the same sound again coming from the loudspeakers and “hey presto” we have a feedback loop.

Stop the Sound from Feeding Back!
A trained sound engineer will know how to prevent feedback but also how to get rid of it should it occur enabling them to get a louder mix out of the sound system. There are many things to consider such as Mic Choice, Speaker Placement, EQ Settings etc and these along with many other points are explained. Correct use of a Graphic Equaliser is one of the ways sound engineers use to get rid of feedback and often before a band perform the sound engineer will “Ring Out “ the speakers ie deliberately make them feedback so that they can then identify the troublesome frequencies and EQ them out. Understanding the best way to do this and how to connect up the equipment is explained in detail in the tech sheets. Finally you can get feedback destroyers which can be good in an environment where there may not be an experienced engineer available such as a rehearsal room, school theatre or church, however the quality of them vary enormously and the cheap models will often protect the system from feedback however the consequence can often be a very dull and lifeless sound. Experienced sound engineers prefer to use their own ears to remove feedback and these tech sheets will show you how.

Don't let feedback ruin your mix and put you off from sound engineering. By learning to conquer audio feedback you can truly call yourself a pro and take live sound mixing to the next level.
