I'm doing a football presentation tommorow, the disco is on a stage, and the manager wants to use a mic on the dance floor. How do I avoid feedback, I was under the impression, if you put a mic infront of the speakers it will feedback?

Andi, depends on the placement of your speakers. You will get feedback if the mic is in front of the speakers, but there are a few steps you can take to avoid this. Make sure your mic is a good quality unidirectional one (super-cardiod) such as a Shure SM58. Try and put your speakers far apart, with the mic on a stand in the middle - this will stop people putting the mic on a speaker. Try and get your hands on a feedback destroyer - Behringer have a couple of models, you may be able to borrow one from someone here if you ask nicely, or hire one, or even buy one - I don't think they are very expensive, but you will need to set it up beforehand. Make sure you have your hands on the tone and gain controls when the mic gets used and adjust accordingly.

Make sure you talk to EVERYONE who is going to use the mic and explain that a) they need to talk into the mic as close as possible - not hold it 6" away, and b) they must hold the mic by the base of the body - not by the capsule as this will help avoid feedback.

Good luck mate, have a good one....

Just EQ the mic, simple.

Thanks,

Daniel

Agree with above.

Dont bother with the feedback destroyer. Waste of time.

Don't feedback destroyer just drop that band, so in effect you could end up with nothing.
EQ it instead

Cheers to all, so how do I EQ the mic, be patient, I'm new and out of th box!

Just tweak the treble, mid and bass. Also depends on the mixer. If you start to hear a "ringing" sound (the sort of echo just before it howls) drop the mid frequencies back a bit more.
