How to kill feedback
« on: Nov 04, 2006, 08:55 pm »
Feedback: The result of a microphone receiving more sound from a speaker than from the source. i.e. someone is pointing a microphone into a monitor wedge, or something of that nature. The signal from the microphone is sent through the mixer, to the amplifiers and then boosted by a large amount. The amps then drive the speakers, which produce a louder version of the initial signal, and it just keeps going in loops.

One way to get rid of feedback, and the most effective, is to change the position of the mic relative to the speaker it's feeding back from. When this isn't possible, perhaps due to the performer's preference, then you must try to eliminate the feedback by adding an eq. This is hit and miss, just pull down one frequency at a time, and when you find the one that works, bring the two adjacent frequencies down a little, then boost the middle one until it just starts to feed back again, back it down a little, and you're done.
