The card is supposed to support AES/EBU standard but it only has a RCA output for digital audio. Am I supposed to use a RCA-XLR cable for such a connection? Would there be a good impedance matching?
Thanks

The 1212m only supports the AES/EBU format and not the XLR interface connection. Do not use a RCA-XLR cable.

Hm, then how is it possible to take advantage of the AES feature on the card

The AES data stream format will not be much different for playback. Things like copy protection info is not included.
Normally a media converter is used to connect between 75 ohm coax and 110 ohm twisted pair.
