Re: placing speakers and microphones

["David Buckley" <db@xxxxxxx>]

What you need to do is to try and aim the sound coming out of the
speakers to be going away from the microphones, which is the first
step in trying to keep the speaker audio out of the mics.

next step is careful equalisation.

There are electronics techniques one can use to try and reduce
speaker sound interfering with mics, like hybrids, but its all a bit
tough in a random space.  DSPs do it for room audio conferencing
systems, but they are not in the least cheap, have a look at Rane
stuff for an example.

Good luck; you are in a difficult area.
