Time Base
The Video Sync generator is the time base (speed) master. It is
hard wired to the video sync inputs of the Digital Time Piece, the
VTR, and the DA-88. The DTP creates the video-referenced word clock
which you will patch to the DM-4800 console. The Word Clock out
of the DM-4800 is normalled to the Digidesign 192 I/O (ProTools).
Address Base
The Digital Time Piece is address base (location) master. It drags
the VTR around via 9-pin remote control. ProTools chases MIDI Time
Code (MTC) by being put online. The DA-88 chase SMPTE Time Code
(LTC) by putting machine 1 into chase.
