I am looking at upgrading our home theater to an Arc Ultra and in ceiling speakers. Just wanting this clear in my mind before I order everything. If I connect the Arc Ultra to the TV with an eARC HDMI, does the amp also need to be connected to the TV and / or the Ultra? From reading it seems that connection happens wirelessly but some of the schematics on the manuals show an HDMI to the Arc Ultra and to the Amp.
Thank you
