ADAT Bridge I/O
42
Hardware Setup
The JL Cooper DataSync2™ translates the
ADAT-proprietary ABS time reference sig-
nal embedded on ADAT tapes into MTC.
The MTC is sent to your computer and
used to trigger Pro Tools from the ADAT
transport. This allows synchronized audio
playback, recording, and track transfer be-
tween Pro Tools and ADAT with 1/4 frame
accuracy or better. For near-sample accu-
rate sync, add a Digidesign USD.
To connect this setup:
1
Make the primary connections as ex-
plained in “Primary Connections (Bridge
I/O to Pro Tools and ADAT)” on page 10.
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.
Software Configuration
The following example uses a JL Cooper
DataSync2 and MIDI Interface to Slave
Pro Tools to the ADAT. In this case, the
ADAT provides both the clock reference
signal and the positional reference, and the
Pro Tools Transport is controlled by the
ADAT. This enables you to synchronize the
ADAT and Pro Tools with better than 1/4
frame accuracy. To achieve near-sample ac-
curacy, a USD or other Slave Clock-capable
sync peripheral is required.
Recording Tracks from an ADAT to
Pro Tools with a DataSync2
This setup explains how to perform a syn-
chronized ADAT-to-Pro Tools track trans-
fer.
To transfer audio from ADAT to Pro Tools:
1
Connect the DataSync and MIDI Inter-
face to your system as shown in Chapter 2.
On the ADAT:
2
Set the ADAT’s clock to Internal.
On the DataSync2:
3
Turn on the DataSync2 after you’ve
turned on the ADAT. This is necessary in or-
der for the DataSync2 to communicate
properly with the ADAT.
4
Set the desired frame rate on the
DataSync2 by pressing the mode button.
You must do this in order for the DataSync
to output SMPTE/MTC.
5
Enable MTC on the DataSync2 by press-
ing the MTC On button.
Configuring OMS Setup for the DataSync2
(Macintosh Only)
If you are using Pro Tools on a Windows
computer, skip these steps.
6
Configure the DataSync2 and your MIDI
interface in OMS.
• Create a device for the DataSync2.
• Enable Send and Receive MTC for the
DataSync2.
• Connect the DataSync2 to the appropri-
ate MIDI port.
