Newbie needing help on feedback eliminators

[BigEar]

Hello all,

I have heard of feedback eliminators for live settings and am still unsure if they are very useful or not. I generally work with very ameteur performing groups in very poor church auditoriums. The performers vary wildly in their use of the microphones and many times error on the side of holding it too far away. (Of course it is always the sound techs. fault no one can hear them).

I have been thinking of getting a DBX AFS224 (decent price) but am unsure of what to expect. How well/fast do these types of boxes track down and eliminate squeals? Can they keep up with roving microphones? When the boxes are working, does the room sound like an overgrown PVC pipe?

Thanks in advance for your help.

Hey,

I have been using one for a few years now. I tell people that if I had to choose one piece of equipment out of my rack to keep, it would be my Feedback eliminator.

The one I have is a Sabine. I think it is the 1020 (or something like that). It is the single channel one rack space unit. I use it on my monitors. It is AWESOME. We never have trouble with feedback anymore and we are able to push our monitors for more gain. It works VERY quickly and notches the frequencies so narrowly that you cannot hear any difference in the sound.

With my unit, you set-up the room by slowly turning up the gain on your speakers. The unit will then notch out 9 frequencies. These frequencies become "set" for the room. There are 3 more frequency channels that "float" to where ever they are needed.

Hope this helps...
