In the Pro Tools Session Setup window:
• Set Channel 1–2 input to ADAT.
• Set the Pro Tools Sync Mode to ADAT
Optical.
• Choose the sample rate that matches the
sample rate of the material on the
ADAT(s).
4
In Pro Tools, create the number of desti-
nation audio tracks you want to transfer
from ADAT. Make sure the destination
tracks each have a different voice assign-
ment in the Pro Tools session.
5
Use the Input Selector of each destina-
tion track to assign its input. With the
ADAT Bridge I/O as your master Pro Tools
interface, this is done for you automati-
cally: Pro Tools track inputs 1–8 corre-
spond to Group A optical inputs (1–8) and
track inputs 9–16 correspond to Group B
optical inputs (9–16).
6
Select a Pro Tools monitoring mode
(Auto Input Monitor or Input Only Moni-
tor).
7
Record enable your destination tracks in
Pro Tools.
8
Click Record and then Play in the
Pro Tools Transport window.
9
Press Play on the ADAT to begin play-
back.

When you have finished recording,
click Stop in the Pro Tools Transport win-
dow and press Stop on the ADAT.
Recording to Pro Tools Using
the ADAT Device Analog Inputs
Depending on your setup — particularly if
you are using the ADAT Bridge I/O as your
only Pro Tools interface — you may want
to record into Pro Tools using the ADAT (or
ADAT device) analog inputs. The following
section explains how to connect and play
an audio source through your ADAT and
record it digitally onto your hard disk. Be-
cause most ADATs have no input attenua-
tion controls, you must control your audio
input levels at their source, using an instru-
ment preamp or mixing console.
This setup also applies if you are using an
ADAT optical interface-equipped digital
mixing console and want to record into
Pro Tools using that console’s A/D convert-
ers.
▲ The original “blackface” ADAT (but not later
models such as the XT, LX20, or M20) inverts
the polarity of analog input signals. Material re-
corded into Pro Tools through an original
ADAT’s analog inputs will have its polarity re-
versed. To compensate for this, you can use
the “Invert” AudioSuite Plug-In in Pro Tools to
return the signal to its correct polarity.
To record audio from ADAT inputs into
Pro Tools:
1
Connect your audio source(s) to the ana-
log input jacks on the back panel of your
ADAT.
2
Set the ADAT to analog input.
3
On your ADAT, enable All Input Monitor
button.
