One of the things that I do when I share a PA with other performers and there’s no official sound person is take a picture of my settings.
This allows me to turn my channels down when I’m not performing. That way I don’t need to worry about something getting on my mic’s wireless channel or my music getting bumped and playing.
Turning down or muting any active channels you’re using is a courtesy for other acts you’re working with. It’s easy to do and if you take a pic, that pic is reliable to reset you audio.
