This year we are using these little monitor mixers. They are hooked up to the main digital FOH board via ethernet and allow each of us to change and store our own mixes, eliminating the need for a monitor engineer. We could plug directly into these, but prefer the limiting capability of our Shure monitor amps. And Brandon needs to use the wireless Shure monitor pack anyway.
I’ve played a gig at a place that had these and they were a blast to use. I got a little spoiled afterwards and it took me a while to have anything nice to say about any other monitor setup after that
