Main issue with this mixer is that it doesn't have direct out for every channel. Otherwise, it's very flexible, with the subgroups offering some interesting routing possibilities, 6 sends, 4 stereo returns and chunky EQs that add a solid character to my basses, hi hats, and snares.
A very trusty mixer, built like a tank and soundwise it not colors too much. I use this mixer for my live performances. I like the many routing options in the Mackie mixers. The sub channels is really handy for groups for example.
