I understand this RCA output connector goes off to an external D/A converter. Could somebody give me a link showing the nitty-gritty of the data flowing out of this line?
Edit - Is it SPDIF or TOSLINK or something like that?
As mentioned, the data format is s/pdif (Sony-Phillips Digital InterFace). TOSLink is just the name of the physical connector for the optical version of the s/pdif interface.
