DO you guys know if this means I will defo need to upgrade my HU to CCC instead of the Business unit?
There will be no sound if you retrofit Logic 7 option as signals will go to Fibre optic.
I've done Bussiness HU to hi-fi but you have to do the settings manually. Which means it is not possible on Autologic.
