Chapter 9: Working with Pro Tools LE 85
Recording To and From Digital
Devices
Digi 002 and Digi 002 Rack provide both S/PDIF
(RCA) digital input connectors and Optical con-
nectors for transfer of digital audio.
Setting Digital Format and Clock Source
Before recording from a digital source, make
sure you have enabled the appropriate Digital
Format in the Hardware Setup dialog. For more
information, see “Recording a Digital Source”
on page 27.
Recording To and From an ADAT
You can use Digi 002 or Digi 002 Rack to inter-
face with an ADAT, either to record tracks from
an ADAT into Pro Tools LE for editing, or to
record tracks from Pro Tools LE to an ADAT.
To record ADAT tracks into Pro Tools LE:
1 Open or create a session in Pro Tools LE.
2 Record enable up to eight audio tracks (de-
pending on how many tracks are used on the
ADAT tape).
3 Assign ADAT Optical Inputs 1–8 to your eight
tracks.
4 Verify that Pro Tools LE is synchronized to
Optical, and that the Optical Format is set to
ADAT.
5 Click Record in the Transport window.
6 Click Play in the Transport window to begin
recording, then press Play on the ADAT.
7 When playback from the ADAT tape is fin-
ished, click Stop in the Transport window, or
press the Spacebar.
To record Pro Tools LE tracks to an ADAT:
1 Open the session you want to record to ADAT.
2 Record enable up to eight audio tracks on the
ADAT.
3 Route the output of up to eight audio tracks in
Pro Tools to the Optical outputs on Digi 002 or
Digi 002 Rack.
4 Verify that Pro Tools LE is referencing its Inter-
nal Clock Source in the Hardware Setup dialog.
5 Start recording on the ADAT, then click Play in
the Transport window in Pro Tools LE. When
playback is complete, stop both systems.
Monitoring Latency and Recording
Because Pro Tools LE uses the host processor in
your computer for audio processing, playback,
and recording, there is a small amount of audio
delay, or latency, when monitoring audio
through the system. You can set the latency to
be shorter when you are recording and monitor-
ing through Digi 002 or Digi 002 Rack, and
longer when you are trying to achieve higher
track counts with more plug-ins.
For detailed information on connecting an
ADAT to your system, see “Connecting an
ADAT” on page 64.
