I'm confused about something. I have a couple DA-38 machines and a couple IF-88AE TDIF-AES converters. I've got both 38s synced with the normal cable, both are going TDIF to the IF-88AE, and on my Pro Tools interface(s) I've selected to sync to digital wordclock. It seems to work well but I'm confused about TDIF and its wordclock implementation. I've read various things like that the DA88 doesn't support wordclock on its TDIF output (but that the 38 does), and also that TDIF doesn't carry wordclock at all so I don't know what to believe. The IF88AE has no wordclock input connector, only output, so I'm guessing that TDIF does in fact carry a wordclock signal and that the 38 is shooting it out via TDIF into the IF88AE. Shouldn't the IF88AE be locking to that wordclock? If so, what the IF88AE shoots out of its AES ports should be that same wordclock, which would get my Pro Tools interface to lock to the incoming AES wordclock. PS: I haven't transferred anything from Pro Tools back to the DA-38, but I'm guessing that -IF- everything I said above is correct, the exact setup above would also be fine for transferring from Pro Tools back to the DA-38s. The IF88AE has a wordclock output port, but I don't see why I'd ever need to reverse it and make my 38s the slaves with Pro Tools being the master to transfer back to the 38s. The IF88AE manual always shows a wordclock cable from the IF88AE to a DA88 (not 38) when transferring TO the DA88, but never from it. Maybe it's because the 88 can't sync to TDIF wordclock, but again, why would you need to reverse it and have your interface as the master when it's already the slave? Maybe the DA88 is different from the DA38s for some reason in that regard.
