Chapter 2: Connecting Your Studio 15
If you also use a Digidesign 888 24 or
882 20 audio interface, you will most likely
want to use them as your primary audio in-
terface and use the ADAT Bridge as expan-
sion I/O for your system.
▲ This section covers clock connections be-
tween Pro Tools audio interfaces only. Many
synchronization peripherals add their own re-
quirements for clock. Refer to “Synchroniza-
tion Connections” on page 16 for more
information.
To make clock connections to other
Digidesign audio interfaces:
1 Connect the Slave Clock Out of your pri-
mary audio interface (such as the 888/24)
to the Slave Clock In of your next audio in-
terface (such as the ADAT Bridge I/O) using
the BNC cable.
2 Connect any other Pro Tools audio inter-
faces by repeating the above instructions
and daisy-chaining the Slave Clock signal
between each interface.
Step 4: Stereo Monitor
connections (optional)
The ADAT Bridge I/O provides a pair of an-
alog outputs which carry audio output
channels 1 and 2. If the ADAT Bridge I/O is
the primary audio interface, these will be
Pro Tools output channels 1 and 2. If you
are using the ADAT Bridge I/O as expansion
I/O, then these outputs will be channels 1
and 2 in the bank of outputs represented by
the ADAT Bridge I/O’s Group A channels.
The illustration above shows a single exam-
ple setup in which the ADAT Bridge I/O is
the primary Pro Tools audio interface (in 8-
channel mode). If the ADAT Bridge is being
installed as expansion I/O, then its 60- to
50-pin Interface cable would be connected
to a different interface port than the pri-
mary disk card.
This simple configuration allows track
transfer and mixing of ADAT tracks be-
tween Pro Tools and ADAT, but has no pro-
visions for synchronized playback or re-
Slave Clock and interface connections with an
888 24 and an ADAT Bridge
