Sorry for the slow reply. Yes, the mk.2 (fully wired) Powerlink cable is the one to use when the speakers and Ouverture are in the same room. This way, the Passive should be used without an IR eye connected, as all remote control commands will come directly from the Ouverture and the Passive will function as a simple power amplifier.
I’m always happy to help with any cables via my sponsor link below.
Kind regards, Steve.
