ADAT Bridge I/O26
• Insert an ADAT tape. If you have multi-
ple ADATs, there must always be a tape in 
the master ADAT. 
3 Turn on synchronization or other MIDI 
peripherals/interfaces.
4 Turn on the Pro Tools Audio master in-
terface. Depending on your studio setup, 
this could be the ADAT Bridge I/O, or it 
could be a different Pro Tools Audio Inter-
face.
5 Turn on any additional Pro Tools Audio 
Interfaces.
6 Turn on your computer. 
Basic Settings
There are several software settings that you 
need to configure after installing the ADAT 
Bridge I/O. 
The following instructions explain how to 
make these basic settings. In most exam-
ples, the ADAT Bridge is the primary 
Pro Tools audio interface. Using the ADAT 
Bridge I/O as an expansion interface has 
special requirements which are noted 
throughout this guide.
Trashing the DigiSetup file
(Macintosh only)
If you are using a Macintosh computer and 
are adding the ADAT Bridge to a previously 
installed Pro Tools system, you will need to 
throw away your DigiSetup file before you 
open and configure Pro Tools. This file is 
located in the Preferences Folder which is 
inside the System Folder. Restart your com-
puter and proceed with the instructions 
that follow.
Configuring the ADAT Bridge for 
Pro Tools
To configure Pro Tools software:
1 Launch Pro Tools. Depending on your 
setup, one of the following will occur: 
• If this is the first time you have installed 
and launched Pro Tools software, you 
will be prompted to choose the Audio In-
terfaces connected to your system from 
the Playback Engine dialog. 
• If you have previously installed and 
launched Pro Tools, choose Setups > 
Playback Engine.
Playback Engine (Macintosh) with ADAT  Bridge I/O as 
the primary audio interface (note the Card popup 
setting “d24 #1”).
Playback Engine (Macintosh) where ADAT Bridge I/O 
not the primary audio interface (note the Card 
setting “DSP Farm #2”).
