Hello! https://www.behringer.com/Categories/Behringer/Mixers/Digital/XR12/p/P0BI6#googtrans(en|en) This mixer is controlled by tablet but tablet has its own volume down and up fuction. Is tablets own volume control affecting any way the output sound of the mixer? Can tablets volume fuction set to be working as a main volume gain? In my case I need tablet for the sports club music kiosk. I need to limit the volume with scheduler. The volume limiter app works with tablets output sound only. I hope I was specific enough :) Thank you!
