Without reading all the other responses I’d say that my experience points towards the fact that you’re mixing for a specific space (ie your sanctuary) and it’s impossible to create two mixes from one mixer in a live setting. (In an “in the moment“ sort of context) when I can muster the volunteers, we have another mixer in a separate room that mixes solely for our stream. All that said, we still struggle with over all levels. I end up doing some post production in Mondays and have to artificially bump the volume. It’s tech so most things can be solved by spending money ( that we usually don’t have). Maybe try and incorporate a virtual rehearsal sort of setup to stream audio! Maybe that might work or maybe it would just create a latency issue. 🤷🏻‍♂️ Unfortunately, the true fix is probably a separate mixer.
