It is confusing though, as you say "75r in" would make more sense.

Yes, for one very generous moment, that thought did cross my mind - then I thought again. Since the 'box' is an external device and will have an Zin of 75 Ω 'looking into it' from the gen., then it should be labelled "75 Ω" - as I stated in my post to which you refer. If I picked that adapter up, I would go looking for a generator that had a Zout of 37.5 Ω.
