Okay, I just purchased an Audiophile 192. It works great! I just wanna know what exactly S/PDIF does. I don't know alot about recording, so if you can put it in simple terms, that would be good.
If I may add to the above, this was commonly used when transferring audio digitally between the above devices and computers. I think some mini-disk players also have this protocol??
I used to master onto DAT and then, when CDs were more reliable and cheaper, needed to transfer the songs back to my computer for archiving so I did this digitally. The S/PDIF signal includes a clock for synchronisation between devices. Very important to know which device is set to master or you'll get a really nasty hiss when the signal can't lock onto anything
