Trying to setup my singer but get feedback

Ok, my music room is about 12x15 (Didnt really measure) or big enough for a drum kit, a desk, a couple amps and some chairs. The problem im having is setting up my singer. We keep getting feedback with the microphone. To get the vocals even close to keeping up with the volume we are playing seems impossible. The amp the singer is singing out of has more than enough power to push the wind we need but it keeps squealing.

I have tried putting the singer on one end of the room, and the amp on the other end. I tried to put the singer int he closet, adjusting knobs ect ect. Im thinking about getting an inexpensive PA system, but not sure if thats going to solve my problem.

What are you running the singer through?

A 300 watt guitar amp. I know a microphone dont belong on there but I figured I would try. After doing this thats when the squealing question arose about resolving that with a PA.

I guess that is your main problem (the guitar amp). The microphone (Hi-Z or lo-Z?) and its pickup pattern might be another. You need to point the mic in a way according to the pattern so that it picks up the sound from the speakers as little as possible. Anyway, I'd recommend you go get an active monitor for him, a Behringer with enough watts cost perhaps 300 bucks. I have one, it's not great but works OK and it's 450 watts.

Basically you are trying to make a guitar amp do what it isn't intended to do and hearing the results.

Guitar amps and speakers are designed to emphasise particular parts of the frequency spectrum, to sound good for guitar.

For singing the ideal is to have a flat response, because any specific emphasise of frequencies is going to escalate into feedback very quickly, and a guitar amp doesn't have enough control to control those specific frequencies.

Additionally, lower quality (cheaper generally) mics will also have a non-flat frequency response, which will interact even more with the guitar amp frequencies.

Best bet would be to get a small powered speaker, a small mixer a good quality mic and either a feedback killer or a 31 band eq. That should be enough to get volume up to what you need.
