You do not want to use an adaptor. Make a cable with a BNC on one side and an RCA on the other. RCAs used for an SPDIF cable are special. You can not use just any old RCA without killing bandwidth. You can use an SPDIF cable for an analog signal but not the other way around.
S/PDIF-how different than an IC?
I posted this on "Cables" too. One has a 75 Ohm spec and one does not. One comes in pairs and one comes as a single. Both typically have RCA's though some have BNC's. How does a cable producer change the spec on what outwardly appears to be an identical cable? If you specify from a cable producer that you want an S/PDIF how do you know they are not simply selling you one half of a pair of off-the-shelf IC's? And last but not least, how does 75 Ohm change the sound one would hear from a normal IC (when carrying digital signal rather than analogue of course)?
I know this much; a very well-respected engineer with a Ph.D. in EE who designs and produces DAC's of his own says that you are free to experiment with using a normal IC with his DAC's rather than a dedicated S/PDIF.

I make my own cables. SPDIF cables are made with high bandwidth 75 ohm coaxial wire and special RCA plugs with crimp on pins to maintain that bandwidth or BNC connectors. AES/EBU cables are high bandwidth balance wire with standard XLR connectors. Regular interconnects technically do not have the bandwidth to support the higher frequencies required to pass on dense digital information such as 192/24. Only a single cable is required as both channels are contained in the signal. |
auxinput, this is the one I use. http://www.canare.com/ProductItemDisplay.aspx?productItemID=40 |
