The job of the mixer is always to fill the holes with whatever hasn’t been done and do it efficiently and without need for praise. The mixer is there to make sure the designer’s vision comes to life and to make everything feel effortless and smooth. There are mixers who pride themselves on how little the designer has to do. In the end, the less the designer has to worry about the little details, the more he or she can concentrate on the big picture. If the designer is trying to help fix intercom problems, he can’t focus on why that reverb isn’t working. When a mixer does his job right, the designer is relaxed and only has to think about the sound of the show. The mixer’s job is simply to make the system work without drawing attention to the sound department.
