I have 2 Mackie 1202's which give me 8 mic pre's. But what I do is mic my drums, usually with 6 mics.
Kick
Snare
Rack Toms
Floor Tom
2 Overheads
I run each mic to a separate xlr pre on the Mackies, then out the Mackie INSERTS. The 1402 has 6 of these. By using the inserts, with the 1/4" jack all the way in, you bypass the main outs and the eq's, but you get 6 discrete channels and the use of the pre's.
If you have 6 or more ins on your recorder, this is a good way to go.
If you only have 4 ins on the recorder, still run your mics to the xlr pre's, but send one stereo mix to the main out and another via the Mackie alt 3/4 by muting those channels. The manual is very clear on how this works. If you don't have one, the Mackie web site has a .pdf.
