Mano1: "can you use the analog ins and outs instead?"
I already do, and I need as many inputs and outputs as possible!! That's why I'm looking for a Analogue<Digital>Analogue converter. I've browsed for DAC's, and seen some that were way out of my league, industrial-class equipment capable of working in degress from below zero, to 70° celcius. I DONT NEED THAT!!! I just want a compact (cheap?) box that can do the job!!!
