ADAT Bridge I/O44
Bridge I/O’s Group B inputs. If you have ad-
ditional ADAT Bridges/ADATs, assign their
inputs as well. (When Ch 1-2 input set to
ADAT, Pro Tools automatically sets I/O
pop-ups to ADAT Bridge Group A/B input
& output labels.)
12 Select a Pro Tools monitoring mode
(Auto Input Monitor or Input Only Moni-
tor).
13 Choose Display > Time Code.
14 Choose Setups > Preferences, and then
click Operations. Choose the desired
Pro Tools online recording mode:
• Record Online at Time Code (or ADAT)
Lock
– or –
• Record Online at Insertion/Selection.
If you are not familiar with these modes, re-
fer the to the Pro Tools Reference Guide.
15 Record-enable your Pro Tools destina-
tion tracks.
16 At this point, you may wish to confirm
that time code is being received by
Pro Tools. Do this by pressing Play on the
ADAT. The Current TC counter in Pro Tools
Session Setup window should begin run-
ning. Make a note of the SMPTE frame
number where the time starts. If there ap-
pears to be an offset, you’ll need to enter
the offset number as the Pro Tools session
start time in the Session Setup window.
17 Rewind the ADAT to a location at least
10 seconds before the time code address at
which you want to start Pro Tools record-
ing. This provides adequate time for
Pro Tools to lock to the time code and start
recording.
18 Put Pro Tools online.
19 Click the Pro Tools Record button.
20 Press play on the ADAT’s transport.
Pro Tools begins online recording.
21 When you have finished recording,
press the ADAT’s Stop button. Pro Tools
will stop recording.
Recording Tracks from Pro Tools to
ADAT with a DataSync2
This section explains how to perform a syn-
chronized Pro Tools-to-ADAT track trans-
fer. In this case Pro Tools provides the
clock reference signal and the ADAT pro-
vides the positional reference. If you are
laying audio back to a specific location on
an ADAT tape (after editing or processing
them in Pro Tools, for example), you
should cue the ADAT tape near the point
where you wish to layback.
Also, be aware that because this is not a
sample-accurate transfer, the tracks that
you lay back may be a few samples off.
Sample accuracy is generally only a critical
concern with phase-synchronous material
such as audio recorded with multiple mi-
crophones (a pair of drum overhead mics,
for example).
In such cases, you should transfer the
phase-synchronous material in a single
pass. That way, whatever delay is intro-
duced will be introduced equally to the ma-
terial, maintaining its phase coherence.
To transfer audio from Pro Tools to ADAT:
1 Make sure the DataSync2 is configured as
described in the previous ADAT-to-
Pro Tools setup.
2 On the ADAT, set the ADAT’s clock to
Digital.
