In a musical/theater production we typically share 10-15 wireless headset systems among a number of actors for 10-15 songs. My A2 is backstage-I find it helpful to use Mixpad (used Qpad in a QU previously) to verify mics are hot. Currently, I use Guided Access on the iPad to lock the screen on meters. It would be much more user friendly if I could allow a “read only” access to the mixpad of some sort. Perhaps restricting to only the meters screen.
