Thank you. So in practice does this mean i need to use the coax out and make sure any recorder i am going into goes via coax in?
AES/EBU is typically 44.1 and up (really 44.056khz is the starting point and possibly slightly less with pull down)
SPDIF supports 32khz and up
Some newer recorders (Sony D50, Tascam DR-100mkii) are more picky then older ones when it comes to locking to a signal (so you may need to try both AES/EDU and SPDIF to lock) - some decks have the option of setting the format of the signal (i.e. DR-680)
32Khz tapes are pretty rare but they are out there as the alot of portable DAT decks supported this format and some tapers would run at LP(12bit 32khz) or 32khz to conserve tape
I have taped 100's of shows and all was at either 44.1khz or 48Khz (probably 90%)
Out of the 100's I have transfered for people only a handful where 32khz (maybe 5-8 total)
AES/EBU does not pass copy bits (SCMS) so in the old days of DAT cloning it was preferred (the locking XLR's are nice as well)
