Optical inputs to 24 4 2

Greetings. I am starting a new project that will require me to take 24 channels of optical output from an RME 9652 and get them into the 24 4 2 for FOH mixing.

Any ideas?

Maybe I'm missing something, but if the audio is already in your computer, I think the best bet is to output it via FireWire straight into the studiolive, even if you don't have the card already.
Otherwise you could output the optical into D/A converters and then into channels on the board, but I can't think of a compelling reason to do it that way.
If there's more to it, please provide some more info and I'm sure someone can get you in the right direction.
