An analog mixer would have to still output to the two available audio channels.

You wouldn't be able to get separate stereo tracks that way and editing in the host software would be restricted because of that.


A mixer with S/PDIF output would be a horse of a different color in this situation, as it would be able to do the same as the Mic Preamp, take analog input signals and convert them to digital signals, introducing them on the "other" two channels of the 0404.
