Funny, my first post two days ago was a recommendation of Jensen transformers. I’ll do it again here and suggest the PC-2XR

Regarding the Canare XLR-m to RCA adaptor: I don’t recommend it. It shorts pin 3 to ground. I prefer connecting pin 2 to the RCA + and pin 3 to the RCA ground using a shielded twisted pair cable. Its shield would terminate to pin 1/shell of the XLR.
