Thanks, Dan, Phil, John and others.
Ok, I will not connect 3 and 1 together to the shield.
Maybe I should elaborate a little more on the specific application.
For outlasting the two HiMD recorders I owned, I still use my old Sony MZ-N=
707 MD recorder for nature recording with PIP mics. The n707 has only analo=
g output via the 3.5mm headphone jack. Because I question the quality of i=
nputs the audio interface to my computer, I would rather use the inputs on =
my SD702 which are almost certainly a couple good steps up in quality.
The only line inputs on the SD702 are the xlr female inputs switchable from=
mic to line. So we are talking about hardware to hardware, unbalanced to b=
alanced.
Referring to the Rane webpage John Tudor pointed to,

The closest diagram I think would be number 13 but modified for stereo. So =
in in words, 3.5 tip to left xlr 2, 3.5 ring to right xlr 2, 3.5 sleeve to=
left and right xlr 3, and xlr 1 to the cable shield which is not connected=
to the 3.5 connector.
Would that be the best configuration?
