Just to add to what Lee said. If your in multi band festival type event with one sound provider and show up with your monitor rig don’t plan on getting a digital split. Even if the systems would be compatible the possible set up and routing glitches that could happen during a tight band change over would get a no go from the provider.
If this is stand alone monitor rig plan on putting a good analog split snake in the rig.
If I’m providing for a multi band band event I carry my own spilt with me.
