something to do the "balancing" operation and output 3.5mm

Yo! I'm a programmer but I need to figure out some audio stuff for work, any advice would be amazing! I don't like asking things unless I've done my fair share of work too, so here goes:

I'm replacing a lecture-recording box (this one - link to wiring documentation) with a different lecture recording box (this one). The old box accepts a 5-bare-wire balanced input (ground, and then 2 wires for left-channel and 2 wires for right-channel). The new box only accepts a simple stereo 3.5mm jack input.

I just read an article about how balanced wires work and it seems really cool and clever. My question is: can I buy a small box that will accept balanced bare-wire inputs (that are probably running a hundred feet or something), do the balancing-magic, and output an unbalanced 3.5mm signal (that will only travel a few inches, so it shouldn't pick up too much noise along the way) ?

I could just tape-over the inverted signals and be left with 3 wires, and then use one of these 3-wire to 3.5mm thingies, but then I get all the noise from the 100-foot wire, and I want to do this right for my customer.

Any suggestions would be amazing, thanks again! <3

Thinking about this a little more, I could probably buy an audio interface that accepts 2 balanced inputs, and buy some bare-wire-to-LXR adapters, and then take the mixed line-output of that. Is that the best option?

It can be a little tricky going from a balanced output to an unbalanced input.
Why? Because there are three different types of unbalanced output stages and one adapter won't work for all three types. Then getting from two cables to one adds interest.

This paper has some info, but maybe not exactly what you want to know.
