Hoping someone here has some in-depth knowledge of the spdif protocol.
I have a very old Pro Tools system which I use on a daily basis. The AD converter is a Digidesign 882/20 io, which is specific to the DAW. The inputs are legendary for being a bit rubbish so I'd like to upgrade the converter (I know, it should have been junked 20 years ago but it works and for what I use it for it's more than adequate.). The soundcards for the Pro Tools system will only accept data from the digidesign converter though.
I'd like a Rosetta but even the used ones are bonkers money. So I'm interested in a Focusrite PRO40 Saffire. It's got an RCA type spdif output and the 882 has an RCA type spdif input so I'm assuming I'll be able to put audio into the saffire, transfer the digital signal to the 882 and on to my 21 year old G4 mac.
Now, the spdif signal from the Saffire will be 24bit, but the 882 is only 20bit. I'm aware that in the transfer the extra 4 bits will just be junked but will there be any other potential problems apart from a slight loss of resolution?
I've read plenty about going from low bit depth to high bit depth but can't find anything about the consequences of going from high to low.
Any help would be very much appreciated.
