According to Wikipedia S/PDIF is defined to be unbalanced 75 ohm. If your output is balanced then it isn't S/PDIF. It could be AES3, which can be balanced 110 ohm. Or it could be a private homegrown protocol loosely based on S/PDIF.

I realize that, but given the lack of info I just lumped them together. AES3 can also be BNC or XLR I guess we need more info from the OP and whether he just wants it to work, or get the best he can out of the connection
