OK, while I'm well aware of the feelings regarding feedback eliminators on this forum I would appreciate any suggestions on which make and model to purchase.

The DFR22 is my go to when i need one.

John....

A bit more information would be helpful.  What's your situation and your application?  What other gear will it be used with?

I'm one of the first to question the use of such devices, but use them myself and find certain of them useful for specific purposes.  They are, as you know, not a panacea....but for a specific purpose in the hands of a knowledgeable user they do offer some functionality.

All that said, I've used everything from a Peavey Auto-graph, Behringer FBX1100, Sabine "Solo" units and my favorite, the Sabine GraphiQ.  The GraphiQ offers a lot more than simple FBX.

I use a dbx afs224 for lav mics in a presentation setting.  Handhelds and anything musical gets a 31 band eq.

I have had good results with the peavey feedback ferret.  I have used them on groups of floor mics and overhead choir mics to give a few extra db's.  They seem to take small chunks and leave a pretty usable tone.

These devices help significantly when using wireless lavs in multiples. When you're following a script and don't have the time or focus to deal with a graphic eq.

Thanks.

+1 on the GraphiQ. Dick helped me find a good used one a few years ago, and it was the most versatile tool in my kit. Sometimes it served as FBX, sometimes as a second crossover, sometimes as main EQ, sometimes as limiter/compressor. Mostly, it filled several of these functions at once (because the budget I was given never had enough to do what I should). I'm certainly not the most skilled user in this forum, but I was able to make some real improvements in my system using that one piece of equipment.

My application was primarily spoken word (with some warm-up/walk-up recorded music).

(As an aside, Dick, I'm starting to buy some equipment for my own kit. I'm going to have to look for another workhorse like that this year.)

Thanks for the info.

The thing that helps me most in this scenario is auto-mix.  I use multiple Shure SCM410's for this.  As to dealing with lavs in multiples, the Sabine Solo units should work very well for you.  Set up is quick and easy, 8 filters/unit, works on groups with an insert.

In addition to auto-mix to keep only necessary mics open and gain-leveling, I also find that a quick polarity flip will usually help when two particularly interactive mics get close to one another.  Doesn't matter which one you flip.  As soon as person A gets near person B and you hear it start to hot up, flip one or the other and you'll usually be fine.

The FBX units will get you a bit more GBF, an auto-mixer will get you that much or more and the polarity flip will help solve the rest of it.

PS

The full GraphiQ will give you more filters, delay, variable-Q graphics and on-screen control from a laptop including the specific frequencies of any "auto-set" filters.  You can also use however many of the 12 filters/channel you wish as PEQ'S.  I use the "black-box", single rack-space models.  I have eight channels of GraphiQ in a four-space rack.  I also carry two of the Solo single channel units.

I have four of the Behringer DSP110 "sharks" if you want a bargain. They do work well for a delay module too, just PM me.

Thanks Dave

Dick is right on here. I happen to prefer Shure DFR11 or DFR22 units for processors and IRP Voice-matics for manual automixers but otherwise we are doing the same things. The Shure and Sabine units are head and shoulders above all the other feedback elimination systems I have ever used. I prefer Shure because in my experience the Sabine algorithm mistakenly interprets sustained handbell notes as feedback while the Shure implementation does not. I prefer the IRP automixers because they have preouts allowing easy connection for both manual mixing via a console or automatic mixing to a dialog channel on the console with no additonal mic splitter. IRPs also have three band EQ plus a HPF on each channel plus a natural sounding onboard AGC circuit. On the downside IRP units do not have the Shure Maxbus comparator circuit so they will open up more than one channel for the same signal if say a user with a headset on walks to a lectern microphone, this situation won't cause feedback as the IRP will open both channels at a lower level keeping the same total gain but it will sound off. Plus IRP is out of business and Shure obviously is not.
