Two Phantoms as rear AV channels (bypass Dialog)

[JohnnySix]

Yes, I do want to eliminate the Dialog. I was just trying to clarify if one has to use it during configuration, but can then remove it once all phantoms have been told to play from their -individual- optical input feeds. That individuality is the essential problem though, they are designed for sharing their signal with a partner, but whether that applies across rooms is still unknown to me.
