I am having a problem with feedback. I found out what was causing it. I now need help resolving it. Here is the problem:

I have a TV Stand with the microphone holders on the side. I have a Microphone on both sides. The right side when turned up is fine. If I turn up the left microphone it causes feedback only when in the stand. Once picked up the feedback goes away. I turned off the TV and the feedback went away. I have tried muting the TV and turning the volume down. What else can I do. I have not been able to figure out why this is happening and do not want to go back to the old microphone stands because I went through more microphones due to them being knocked over.

All sugestions are appreciated.

I use the "PAD" buttons on my Yamaha amp to control the mics, and I have all the mics switches in the "ON" position, with electrical tape taped over the switch so that a singer can not control the "on/off" switch. I leave the mics "PAD"s off until a singer is getting ready to sing.

This way, only I control when there is an open mic.

Keep the mics off when they are in the stand.

You don't mention if you have "mute" features on your mic channels or not. If so, turn them on when that mic isn't in use, if not, turn that mic down until needed.

Even though Lonman won't agree with me,

see http://www.karaoke-forum.com/viewtopic.php?t=2090


adding a feedback destroyer (Behringer Feedback Destroyer Pro DSP1124 @ $100,00) is a worthwile investment. See no matter what type of mic's you have, feedback is a natural thing and depending where you play, you may or may not have it.

That has been explained to you in the other thread & yes I do not agree the Behringer unit is very good for feedback control. Peavey makes the Feedback Feret & dbx now has a new one out as well - AFS224. This one uses the narrowist bands to minimize sound distortion or noticeable sound change. 24 filters per channel as opposed to 12.

The DBX AFS224 Feedback Eliminator is at least $300, and the Feedback Ferret® II can set you back $300. If you don't have the money, the Behringer is still a good option. And yes I agree, not the best money can buy.

Proper speaker placement will eliminate most if not all feedback along with not pointing mics at each other. I think I can count on one hand the number of times we've had feedback and we have no "eliminators".

If the feedback is happening when ONLY in the mic stand ..Then do what is suggested and mute the mic until in use. You might also try a little differant speaker set up or monitor placement .
If the feedback problem continues or MAGNIFIES you may need to go out and get some sort of suggest processor or FEED BACK ELIMINATOR.

this is probably a dumb statement, but check to make certain the tv monitor doesn't have volume coming out of it...

On the left side of your TV is the high voltage vertical output side. It sounds like your mic is picking up the RF noise from it. You could try another TV, Move your mic, or do like the others have suggested and mute your mics. Put a piece of aluminum foil between your TV and mic and see if the hum stops.

Thanks for the input everyone. I will try some of the easier and cost effective stuff first.

I have noticed that I get a hum when I put a microphone in the left holder on my tv stand as well. I'm pretty sure it is electrical interference from the tele. I always keep that mic switched to the off position.

I always keep unused mics muted, but mainly so I don't have to worry about someone uninvitingly "helping" the singer. If a person wants to look like an idiot singing into a muted microphone, it's easy enough for the real singer to take a couple of steps away so they're not thrown off. I won't turn the other mic up unless the singer gestures that it's OK.
