Feedback Eliminator

[billyo]

in my opinion they won't do you much, if you have a separate channel eq's, just turn the highs down, i know a kj and he had a feedback elliminator and i used to see him tweaking the elliminator everytime a new singer comes up, what kind of board and speakers do you have..just curious..

I have a pair of Wharfedale pro Titan 12 Active speakers, Vocopro KJ-7808RV Mixer and Kam Kwm twin radio mikes. The mixer also mixes video because I prefer to play singers own disc's from my DVD/CD Karaoke player rather than use the Disk option in Hoster.

i'm not familiar with the vocopro mixer, since i have never used it, i know that whaferdale speakers has a mic and cd/tape input at the back of the speakers ,and also can be use as a floor monitor, but are you daisy chaining the speakers and plugging the mic in ?, whaferdale has a high and low eq's, maybe you can turn the highs down ( if your daisy chaining and mic plugged in ) and also it's best if you have them up on a speaker stand.

I have everything plugged into the mixer, from the mixer I usually use left channel to one speaker, right channel to other, sometimes I daisy chain depending on the location. Left & right channels to one speaker then output from that speaker to the input of the other one. they are on speaker stands. I can control the feedback by adjusting the high & low frequency or the gain on the Mic's on the mixing board.
It is just that I wondered if these Eliminators were any good, by your first answer I see you are not impressed with them.
If I don't get any positive responses to this I will dismiss the idea of using one.

Thanks for your response.

sorry, i'm not really impressed with feedback eliminator, due to what i've seen from a fellow kj.. don't take my word for it.you can try it, if you buy one make sure to check the return policy, just incase you decided to return it..

Hey Roy,
Being able to run pro sound is one of my curse/blessings. I have never used a feedback eliminator because they basically do what you can do with your board and a good EQ. The first factor is like you said, getting the singer to keep the mic close to their mouth. The second factor like you said is teaching then to keep their back to the speaker. The third factor is the overall volume and the fourth factor is finding the frequenccy that is giving you feedback and turning it down on the main EQ.

Here is something you can do that will help. When you get set up, run a sound check. Have somebody stand in the worst place with the mic open and turn the overall (main) volume up some. This will kick up the feedback. Once the feedback is ringing, start pulling down the EQ faders on your main EQ (32 band if possible). When You find the frequency that is causing the feedback pull that fader down and pull the faders on either side of it down just a bit. After this is done you should be able to turn the main volume down to a resonable level and make your EQ adjustments on the channel EQ's to tweek it in. By doing this you are doing what the feedback eliminator does. Oh, when folks hear the feedback, be sure to announce that they are all now sterile. This always gets a chuckle.

I Hope This Helps

Jim

Thanks for your information Jim. I will do some experimenting over the next few days, see if I can pinpoint the worst frequencies. Save myself a few £ at the same time.

I love that mixer, basically because it does pass the video through from all 3 input channels along with the audio.
I have a Balenger 32 channel Equalizer with the feedback eliminator built in and I do find that when we use it my overall volume is cut-down requiring the amp to be turned up more. Regardless of what feedback eliminator you use you will most likely have to reset it once in a while. They tend to cut down your overall audio and cuts down more as you go along.
Does your reciever for your wireless mikes have any sensitivity controls? If so try turning that down a bit and have your singers hold the mike closer to their mouth. I use the Voco Pro wireless sets and can control this. We have been able to eliminate all except when someone points the mike directly at a speaker from close range. Nothing will kill that except education of your singers.

Thanks for your response Dale.
It is really trying to teach people to use the mikes properly, a lot of new singers seem to get shy and as soon as they hear their self they hold it further away, then I try and increase the volume and get the screech. Then others like to dance about and walk right up to the speaker.

Yes the receiver does have sensitivity control, I think I will play around with that a bit more.
