George, it works, I've tested the Mojo using the supplied TRRS to RCA coaxial adaptor to RCA to another TS adaptor to the Mojo. The Mojo end is a standard mono TS jack where the X5ii has the lineout shared with coaxial. Make absolutely sure you are using the supplied TRRS adaptor that came with the X5ii as the coaxial signal is on the Sleeve and the ground is on Ring 2.
Yes, it works
Or you can use a cable like this one from Dyson Audio.
Relic, that is a nice short cable that you have got there, I could rewire my entire house with the excess cable - if only I was not such a danger to myself.
