Our barn dance band plays in a lot of different venues. We have 4 DIs and a wireless mic for the caller. Some places give us no sound problems at all, and they are often the older venues like town halls etc. However, some venues give us no end of feedback problems, usually if there are hard floors, shiny or glass walls and/or high pointed ceilings with beams. The newer village halls are usually the worst. It's the mic which is the problem, as the instruments are always ok. We have an EQ box, but I'm not sure we are using it correctly. Any technical advice would be very welcome.

without much info to go on about what kind of mic.
ie hand held, on a stand, headset mic..etc...
how you use the mic,
how you position it relative to PA or monitor speakers...

perhaps a new mic with better feedback rejection design...???

Anti feedback notch filter devices, could be an additional purchase,
but if you are not sure you are using existing EQ properly,
they would just add more gear to the learning curve.

Also opinion on effective use of anti feedback devices is divided...

I have heard feedback at dances because the caller was moving around and passed right in front of a loudspeaker. Keep the callers from doing that.

The link above is helpful, but when I clicked, an Instagram popup appeared and would not go away. So I put this in my URL box and got through okay:

I asked my husband about this, because he used to be in theater.

Suppose you have two loudspeakers and a microphone. Set up a triangle, with speakers at two corners and the person using the mic at another corner. The goal is to keep the mic from being right in front of a speaker.

Also, a stage manager taught him that if you have extra cable, avoid coiling the cable. Think of a different method to get it out of the way.

From painful person experience I can vouch for the church website's advice to turn down the volume.
