Every knob above those individual equipment rows controlls the equalizer basically for that specific feed. So you can adjust mics, tunes, etc on the fly.

The sliders are generally used for lazy stuff like volume.

It's obviously more complicated than that, but that's the basics. Oh, and you can place asteroid on them.
