ADAT Bridge I/O40
Recording Tracks from Pro Tools to
ADAT with a BRC
This setup explains how to perform a syn-
chronized Pro Tools-to-ADAT track transfer
with a BRC. In this case Pro Tools provides
the clock reference signal, but the BRC pro-
vides the positional reference and controls
the Pro Tools Transport.
To transfer audio from Pro Tools to ADAT:
1 Make sure the desired Pro Tools session is
open and the Sync Mode is set to Internal
in the Session Setup window.
2 On the BRC, make sure the Gen Sync but-
ton is on.
3 Press the Ext Sync button. (Before doing
this, lower your main monitor levels, as
ADATs can emit a loud pop when the mas-
ter clock is changed on the BRC.)
4 Make sure that the ADAT tape is format-
ted to the same sample rate as the Pro Tools
material you intend to transfer.
5 On the ADAT, make sure that the Digital
In button is on.
6 On the BRC, record-enable the destina-
tion ADAT tracks. Make sure that the same
tracks are not configured as Pro Tools input
sources or a feedback loop will occur.
7 In Pro Tools Session Setup window:
• Confirm that Channel 1-2 input is set to
ADAT (if the ADAT Bridge is your pri-
mary audio interface). If the ADAT
Bridge is not your primary audio inter-
face, set it to Analog.
• Confirm that Sync Mode is set to Inter-
nal.
8 Use the Output Selector of each Pro Tools
track to assign its output to an ADAT chan-
nel.
• If you are using an ADAT Bridge as your
master Pro Tools interface, Pro Tools
hardware outputs 1-8 correspond to
Group A optical outputs (1-8) and chan-
nel outputs 9-16 correspond to Group B
optical outputs (9-16).
• If your ADAT Bridge I/O is not your mas-
ter Pro Tools interface, you must use the
output selector to route each track ac-
cording to how your Audio Interfaces are
ordered.
9 Put Pro Tools online.
10 Cue the BRC to a location at least 10 sec-
onds before the time code address at which
you want to start Pro Tools playback. This
provides adequate time for Pro Tools to
lock to the time code and begin playback.
11 Press the BRC’s Record and Play but-
tons. Pro Tools locks to the ADAT and be-
gins playback. The Pro Tools material is
then recorded to ADAT.
12 When you have finished recording,
press the Stop button on the BRC.
▲ If you are recording to the ADAT and audio
already exists before the punch point, you may
wish to manually “punch in” to avoid erasing a
portion of the existing audio that you wish
keep. To do this, simply press Play on the BRC
to start the ADAT/Pro Tools rolling, then press
the BRC’s Record and Play buttons right before
you wish to begin recording. Refer to your ADAT
manual for details.
