Trigger cable lowers temperatures & power consumption

[Axel]

I believe he is trying to enable sharing inputs on the Companion while using the standard RCA-RCA connection. ( which obviously cannot be done once he replaces with the RCA/XLR connection )

And looking into what type of RCA/XLR cable he should get, 75 Ohm or 110 Ohm.

OK, then tick the "share sources from companion" circle, then you can click on the RCAs to enable them, but you must then connect the trigger cable. I use a 110 ohm RCA/XLRcable, but you can use 75 ohm like the Crystal one supplied.

Edit: even if you connect by RCA to AES/EBU, you can still use the two RCA outputs on the companion next to the AES/EBU socket.
