A simple, slim 8 channel stereo mixer with balanced inputs and master out. It sounds great, I can't perceive any alteration of the sound quality. What caught me by surprise, though, was that the monitor output is mono, which ruins it usefulness for me. There are ways around it (like use the headphone output instead) but still... Now I have an extra knob per channel that just sit unused, which is fine, but also a plug sticking out from the front, which is not very aesthetically pleasing, but works to tap it directly to a monitor controller output when I don't want to fire up the DAW just to hear the things connected to it. As there is no competing product that comes close to it without paying 2-3 times as much, so I'm happy anyway.
