I suspect the author is confused. My delta1010 (IIRC same chipset) has; 8 analogue (balanced) in 8 analogue (balanced) out SPDIF in (stereo) SPDIF out (stereo) ... and the internal mixer can also be recorded too. If I can still count, thats 12 inputs and 10 outputs. I think the delta66 and 44 cards drop analogue I/O and wordclock I/O.
