dow and press Stop on the ADAT.
Recording into Pro Tools Using
the ADAT 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 an-
alog inputs. The following section explains
how to connect and play an audio source
through your ADAT and record it digitally
onto your hard disk. Because most ADATs
have no input attenuation controls, you
must control your audio input levels at
their source, using an instrument preamp
or mixing console.
This setup also applies if you are using an
ADAT optical interface-equipped digital
mixing console and wish to record into
Pro Tools using that console’s A/D convert-
ers.
▲ The original ADAT (but not later models such
as the XT, LX20, or M20) inverts the polarity of
its analog input signals. Thus, 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.
4 Configure Pro Tools as if you were trans-
ferring ADAT tracks as described in the pre-
vious section (i.e., create destination tracks,
select their inputs, and record enable
them).
5 Click Record and then Play on the
Pro Tools Transport.
6 Play the audio sources that are connected
to the ADAT analog inputs.
7 When you have finished recording, click
the Pro Tools Stop button.
▲ In the scenario above, the ADAT stays idle
during recording. There is no need to press the
ADAT’s Play or Record buttons. The ADAT is
merely converting the audio into a digital
stream and passing it to Pro Tools via the opti-
cal connectors on the ADAT Bridge I/O.
