I have a gig in a week or so where I'll be recording 90 kids spread across
the whole front of a church singing and playing Orff instruments. I'll
need mics spread across the row as the church is too reverberant to set up
far enough back to encompass the whole group.

My usual combo is an ORTF pair in the middle with omnis reinforcing the
stragglers to the sides. Mix carefully and always put a little bit of the
right outrigger in the left channel and vice versa.

But RAP always offers new and different ideas. What other neat setups can
you come up with that I might try out?
