How to connect BNC 75 Ohm SPDIF output to Genelec 8260A AES/EBU XLR?

I am planning to connect my brand new 8260A speakers digitally to the amplifier.
I am planning to use Meridian 568.2MM pre-amp for the job.
The output of the Meridian is SPDIF with BNC connection (75 ohms, unbalanced)
The input of the Genelec is AES/EBU with XLR connection (110 ohms, balanced)
I read from the 8260A manual that "single ended" digital input is approved also, but there was no connection instructions.

Is is correct to connect the BNC ground to the XLR pin 3 and hot wire to XLR pin 2 (and leave pin 1 unconnected) to achieve single ended digital connection to 8260A?

My cables are really short (<3m) so I assume impedance is not an issue here?

The maximum recommended run with S/PDIF is 1.2 meters. For best and reliable performance, I would recommend using an impedance transformer: ... naditbnc-m

Thanks for the info. I purchased the Neutrik NADITBNC-MX for the first speaker (1m cable).
The system is working nicely now with digital feed.
