OK, we need to learn the fundamental differences between balanced and unbalanced audio. I'm a great audio teacher but this isn't the place. Look these up and learn the difference. Then you will understand what follows.
If your cable is pre-made and has a single XLR on one end, and a stereo 3.5mm on the other, this is NOT what you need to connect these 2 devices. Just because the connectors fit on each end doesn't mean it's going to work properly. In this case the result is your audio being presented as an out-of-phase stereo source to the ATEM mini, because the + phase of the balanced audio goes into the ATEM left input and the - phase of the signal goes into the ATEM right input. What you get is very thin sounding audio because things start to cancel out, or on single speaker device like a phone a total cancellation altogether.
The best solution for this involves something like the Henry Engineering MatchBox, or the Rolls Pro Match. These devices take balanced XLR in, and generate unbalanced signals coming out. You can then use a regular off the shelf 2xRCA to 3.5mm cable to the mini input.
Another solution, while not exactly proper but works fine is a cable wired as follows...
For Stereo XLR to ATEM
L XLR pin 1 wired to 3.5 sleeve
L XLR pin 2 wired to 3.5 tip
R XLR pin 1 wired to 3.5 sleeve
R XLR pin 2 wired to 3.5 ring
For Mono XLR to ATEM
XLR pin 1 wired to 3.5 sleeve
XLR pin 2 wired to 3.5 tip and ring
Either option will improve your XR18 feed into the ATEM immensely I'm sure.
