I love these Neutrik "Feedthrough" things, no soldering necessary! Sadly, this one is not quite perfect as I can't for the life of me get a Neutrik "XLR style" connector to fit from the rear. You'll have to settle for an ordinary network plug there, while the front gets to have all the professional glory.
I can live with this though, as the "bad" cable is safe inside the rack. I use it for connecting DL16 stageboxes to my M32R and it works like a charm.
