Distance between SPDIF output and AES3 input is about 35ft/10 meters.
I'm gonna need:
Or are there any other, better solutions for this?
I'm gonna need:
- RCA to BNC cable
- NADITBNC-M (Female BNC 75 Ω input - male XLR chassis connector 110 Ω output.)
- 110 Ohm AES/EBU Cable or just regular XLR cable?
Or are there any other, better solutions for this?
SPDIF is lower voltage than AES. To get to AES voltage levels you may need a level shifter, perhaps before the balancing transformer.
Also, all cables are carrying RF so characteristic impedance should be respected.

Some say that AES3 will work even with 0.2V
This solution maybe then?:

Maybe. It appears to have a rechargeable battery to do the level shifting. Looks like it needs recharging every 5 hours or so.
AES3 receivers are usually the same ICs as S/PDIF receivers, but with a different termination resistor on the PCB and without one side being grounded. You therefore have a pretty good chance that a 1:√(110/75) transformer without any level shifter will work, even though it is not standard compliant. Besides the different levels, the channel status bits are also different between S/PDIF and AES3, but there is a lot of equipment that doesn't use those anyway or interprets them correctly anyway.
Okay, then going with the first plan to use passive transformer without level shifter:
- RCA to BNC over 75ohm Coaxial cable (https://www.designacable.com/neutri...75ohm-plasma-coax-cable-cctv-video-spdif.html)
- then 75ohm to 110ohm transformer (https://www.neutrik.com/en/product/naditbnc-m)
- and 110ohm AES cable (https://custom-lynx.co.uk/product/nc3fxx-b-tc110-nc3mxx-b/)
