My setup is in my signature. You can see how I use it live in my YouTube videos.

When I play solo, I don't use the little monitor. I just move the LD Maui system behind me a bit. But with my partner, I need to use the monitor because he doesn't want to hear the main system mix. He has only his vocal in his monitor.
