Hi Dave,
Thanks very much for your quick and knowledgeable reply. As these are super high-end decks, they do have "SYNC IN" jacks (on the S800's) and jacks labeled "EXT REF" (on the S822's). The manual instructs the user to input a blackburst or composite video signal to these jacks, which are looped through to relay the signal to other units. In fact, these are the jacks I use to assist the time code in keeping everything locked together. For the audio, I use the "VIDEO SYNC IN" jack on the Alesis BRC (controller for the ADAT machines), and simply use the incoming video signal to initiate to sync train which does make its first stop at the "EXT REF" jack. I'm not sure if I know what I'm doing, but the entire system locks as long as I use 29.97 drop frame. I haven't tried slaving the VCR's the the ADAT's as I prefer to use the VCR for master control, but I'll assume the Sync In and Ext Ref jacks are functional since the system won't lock without them.
Anyway, I "think" I have the needed sync functionality already (though you definitely know more about it than I do). Assuming I'm already "In Sync", can you recommend a lower-end unit that can be had for a couple-three-maybe five hundred? I know that this is a very old-school system, but I'm so far into it already. I actually had placed a bid on a Grass Valley CV-100 until I realized it was designed for Betamax. Something like that for VHS/SVHS would be perfect.
Thanks again Dave!
