ADAT Bridge I/O30
Prepare Your ADAT Tapes Before You Begin
If you plan to do any recording from 
Pro Tools to one or more ADATs, make sure 
that you have an ADAT formatted S-VHS 
cassette prepared for each ADAT in the sys-
tem (see your ADAT Reference Manual for 
specific instructions). Because this can be 
time consuming, it is a good idea to allow 
plenty of time for formatting before you 
begin recording with your ADAT. When 
formatting ADAT tapes, be sure to set the 
sample rate to either 48 kHz or 44.1 kHz, 
depending on the rate at which you wish to 
record. 
▲ Refer to your ADAT manual for details on re-
cording or playback at 44.1 kHz. Different 
ADAT models have different requirements for 
formatting tapes and/or configuring the unit. 
About Pro Tools Monitoring Modes
Use Input Only Monitor if you wish to be 
able to hear incoming material on record-
enabled Pro Tools tracks before you initiate 
recording. Use Auto Input Monitor to hear 
incoming material only during actual re-
cording. 
Recording Tracks from an ADAT 
to Pro Tools (Unsynchronized)
Each ADAT Bridge I/O allows you to digi-
tally transfer up to 16 tracks at once be-
tween Pro Tools and ADAT. 
To perform the unsynchronized transfer 
described in this section, the ADAT Bridge 
must be the primary interface in your 
Pro Tools system.
This basic setup has no provisions for syn-
chronizing playback or recording of the 
two devices. You will have to manually 
start and stop recording/playback of 
Pro Tools and the ADAT independently.
To record ADAT tracks into Pro Tools:
1 Set the ADAT clock to Internal.
2 In Pro Tools, create a new session or open 
an existing session.
3 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 correspond 
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 being playback 
into Pro Tools.
