Benchmark DAC1 AES-EBU from COAXIAL-SPDIF signal


Hi, I seek your advice on how to benefit from the AES-EBU in the Benchmark DAC1.
I don't have a 110 Ohm AES-EBU source signal to this input, however I'd like to rather deliver a 75 Ohm COAXIAL-SPDIF signal to it.
The classical issue as you understand there's only one Coaxial - SPDIF input.

The Neutrick option would be the choice for it is 50% cheaper than the Hosa. I shall first verify with Pro Audio Stash.
Much Appreciated Onhwy61 and Audiojedi.
Benchmark sells one, I use it on my benchmark. Canare.
