sync blackface and XT20 together
To sync, all you need is a adat sync cable (shielded serial) from the "adat sync out" of one unit to the "adat sync in" of another. Either machine can be the first or "master" machine. The XT20 may work better as the master unit, it has more "locate" points and options available, compared to the older blackface, as well as a faster transport. Remember to keep the tapes separate, do not record on one and then record or playback that tape in the other unit.
