Does anyone know if the SQ series (or the Qu for that matter) will support hear back systems like the ME-1 or ME-500, but that are a different brand? Such as the Avioms, or Behringer, etc.
Not on the ME bus, that is A&H specific.
For Hear Back you need to use the analog input in the hub, or get the version with Dante or Waves in, and a card for the console.
