Chapter 2: Connecting Your Studio 19
Setup B: Synchronizing Pro Tools and ADAT Using a
JL Cooper DataSync2
The JL Cooper DataSync2™ translates the
ADAT-proprietary ABS time reference sig-
nal embedded on ADAT tapes into MIDI
Time Code. With a DataSync2 and a MIDI
interface, ABS is converted to MTC, sent to
your computer, and used to trigger
Pro Tools via the ADAT’s transport. This al-
lows synchronized audio playback, record-
ing, and track transfer between Pro Tools
and ADAT with better than 1/4 frame accu-
racy. (For near-sample accurate sync, add a
Digidesign Universal Slave Driver, or simi-
lar Slave Clock-capable device.)
To connect this setup:
1 Make the primary connections (optical,
50-pin interface and clock) explained ear-
lier in this chapter, then;
2 Make the 9-pin sync connections be-
tween the DataSync2 and your ADAT(s) as
shown in the illustration.
3 Connect the MIDI In and MIDI Out of
the DataSync2 to an appropriate MIDI In
and MIDI Out of your MIDI interface.
