Depends a little on your mixer and what you want to do!

My 24 channel mixer is connected to the 002R like this:

Inputs

Mixer Ch01 - Direct out -> 002R In 1
. .
. .
Mixer Ch08 - Direct out -> 002R in 8

And if I need more channels:

Mixer Ch09 - Direct Out -> Behringer ADA8000 -> 002R ADAT In
. .
. .
Mixer Ch16 - Direct Out -> Behringer ADA8000 -> 002R ADAT In

Outputs:

002R Analog out 1 & 2 -> Mixer In Ch 23 & 24 (Main Mix)
002R Analog out 3 & 4 -> Mixer In Ch 21 & 22 (Cue Mix)

The mixer's control room out is connected to my speakers.

Maybe there is better solutions out there, but this works fine for me!
