How to reduce feedback when using stage floor mics

It's often difficult to understand children talking in a stage play because of muddy room acoustics and poorly designed PA systems that feed back easily. Wireless headworn mics can help, but not every school can afford them or control them effectively. So floor mics are used instead.How about...

Some floor mics do not use a tiny XLR connector at the microphone. The cable is permanently attached so it can be stepped on without damage. Here is an example: http://www.bartlettaudio.com/collections/stage-floor-mics/products/stage-mic-c-1

Brass: Ribbon mics usually sound great on brass because the mics' high-frequency rolloff takes the edge off the sound. Check out Beyerdynamic M160, Cascade Fat Head II, Royer 121. Drums overhead: Small-diaphragm cardioid condensers ... AKG 451 or similar, even the Behringer B5. Grand piano...

As a recording engineer and microphone designer, I recommend putting the mic halfway between the sound hole and bridge, about 1 inch from the low E string. A typical lavalier mic has a high-frequency rise which you might want to roll off with EQ around 10 kHz. If you need more gain before...
