The Eleven Rack is as dumb as any box can be. Set its rig input to S/PDIF In and it will process whatever signal you sent to it.. that includes from hardware based mixers in the interface if they can send to S/PDIF out... which it should take you almost no time to work out if yours can. If not then you could route via Pro Tools, at higher latency.

If you are just processing a live Mic or line input you might be better off sending that straight into the Eleven Rack.
