What? Never heard of this kind of activation. It doesn't suggest me anything when selectin AI Sound. it's either selected or not. In the AI Acoustic Tuning option I can select standard, bass boost.. etc, but thats it. How can I activate this AI sound set up?When you set AI sound, did you select bass boost sends then hit the option to set it up? It asks you to hold your remote in front of you and works out the size of the room and activates it all.
