Feedback Destroyer

[avkid]

I am currently looking for a feedback destroyer of some type that is fairly inexpensive, used(in good condition) or new. If you have any suggestions please relate them to me in a timely fashion.

My advice: don't get a box to do your thinking for you. Feedback Destroyers aren't a good substitute for a well set up EQ. You can train your ear in a matter of weeks to recognize the frequency of feedback and just notch it out manually.

Destroyers are notorious for "deleting" things like flutes, guitar feedback and even female vocals that they interpret to be feedback. And they often don't react quickly enough to correct for catastrophic feedback and even if they do they tend to destroy your frequency response as well as the feedback.

So I would seriously consider getting a good graphic EQ and using this free trainer to get your ears in shape. http://sft.sourceforge.net/

I agree 150% with Jon (bnbsound). A well structured EQ would be your best bet as well as training technicians. I would also suggest watching where your feedback is coming from - ie: singer standing 3 feet from one of the main speakers is going to cause problems even for a good tech. You have to figure out the dynamics of your space and give an approiate microphone as well. We've taken all of our feedback eleminators out of our racks and use them as paper weights now - they were (as was said above) eather too much or would react too slowly to do anything that our audio tech's couldn't do themselves if trained.

Good Luck!

I Agrre with the others.Training your ears is the great feedback destroyer. But if you realy want a machine to do the work for you i'd say Berhinger makes some cheap yet effective.

is there anything out there where i can select the frequency and thats what you hear? cuz this gives it to you and expects you to know it..but if there was a way to play everything 1st and listen then this would be more useful.

i just gave it a try and would definately agree. i wouldnt mind learning what they sound like but with out knowing then im just guess n check ing

Although I agree with the last few posts that a well set up system with a trained person at the EQ is best, I will argue that these destroyers do have a place. As a pro sound technician I often am forced to do a quick PA set up (1-2 hrs) in a location that I have never been in before and jack-a**es using the mic's that do not care enough to learn how to use them. (Corporate meetings are the worst). Although it is common sense, they do put the mic in front of the main stacks and countless other stupid things. You can try to teach them, but they don't listen.

I feel that the destroyer gives me a safety net. It allows me to cue the next CD or to put the bodypack bact together that someone dropped. If feedback occurs, the audience rarely ever notices that a part of the signal went out for a minute when the destroyer acts and I can fix the problem without the squeel. Feedback squeel is always seen as an error of the "sound guy" .

I don't use anything fancy, the Behringer unit is only a couple of hundred bucks and it has worked fine for me. It is easy to use and fairly versatile.

However, given a few weeks to set up for a show, an EQ is the only proper instrument to take care of feedback. In my eyes, a feedback destroyer is a tool to be used when there is insufficient time to properly notch out feedback frequencies - a last ditch resort, if you will.

That's all I do, and I've gone months at a time with no squeal at all. EQ's not easy to learn, but once you do you can just about smell a room and know where it's going to ring.

And to the guy playing with the feedback trainer, if you click above each notch you can sample the sounds.
