Two space it is then! :) Comments still apply. I wish Mackie would make a rack mount unit....something like the 12 channel board, with all mic/line inputs, etc. The thing I don't like about most rackmount mixers is that they are so restrictive on the mic inputs, vs. line...damn stingy. Hell, I don't know why I'm even making suggestions here....I do everything with my FW400 and laptop. But I do recall coveting a decent rackmount mixer and being very frustrated with the options.
