2 Mackie ProFX 12 mixers.
One mixer is used for all tom mics.
The Main Out L and R of the "tom mixer" goes into the Stereo Return of the other mixer.
The "other" mixer is used for 2 kick mics, 1 snare mic, and a pair of overhead mics.
The Main Out of this mixer goes into whatever I want to record with.
I had to get rid Of my 12 channel Mackie proFX because I couldn’t get it to show all 12 channels in logic. It only wanted to do 2 (left and right) which meant all my mixibg had to be done via the board itself
