Ben,

Well, we certainly need more trained audio techs, so I'll help with
your homework. The matrix is a submixer within a mixing desk. As
inputs, it usually takes the subgroups and stereo outputs of the main
mixer. It usually provide 2 to 6 independent outputs to be used for
.... whatever.

Whatever may include: recording, broadcast, lobby speakers, dressing
room speakers, delay speakers, assisted-hearing devices, etc.

Here's an picture of a 10 x 2 matrix on an A&G GL3300 mixer, which is
the smallest mixing desk I know of with a matrix.

Glad to see that you're doing your homework; I'm tired of working with
techs who show up at a gig knowing nothing about the band or the
equipment.

It's a mixer that comes after the mixer. It's inputs are the mixer's
busses, and its outputs are used for all sorts of assorted purposes,
one of which might be the main PA outputs, one might be a broadcast or
recording mix, one might feed the lounge or Green Room.

The reason that it's called a "matrix" is because the controls are
usually arranged as a matrix with inputs on the rows and outputs on
the column or vice versa. If you've ever used a monitor mixing
console, you've seen something pretty close to a matrix mixer, where
you have a whole bunch of auxiliary send pots on each channel, with
each auxiliary send feeding a different monitor speaker or (nowadays)
in-ear monitor.
