Output is continuously active on the
S/PDIF jacks, carrying audio routed to out-
puts 1-2 in Pro Tools. To avoid RF interfer-
ence during S/PDIF transfers, we recom-
mend that you use 75 ohm coaxial cable
and don’t go beyond a maximum cable
length of 10 meters.
8. Slave Clock In/Out
The Slave Clock Out jack is a standard BNC
connector that outputs a 256 times sample
rate “Super Clock” signal for slaving addi-
tional ADAT Bridge I/Os, Audio Interfaces,
or synchronization peripherals.
The Slave Clock In jack is a standard BNC
connector designed to receive a Slave Clock
Out signal from another ADAT Bridge I/O
or other Digidesign audio interface, or a
Digidesign synchronization peripheral
such as the Universal Slave Driver. Because
crucial timing data is passed via these
ports, you should use high-quality, 75 ohm
RG-59 cables for making connections and
keep total cable lengths to less than 3
meters between all connected devices.
9. Word Clock Out
The Word Clock Out jack is a standard
BNC-type connector that outputs a word
clock signal. This jack is typically used to
connect the ADAT Bridge I/O to a BRC or
other sync device which requires a separate
word clock input for properly resolved
sync.
10. AC Power Input
This connector accepts a modular AC
power cable. The Digidesign ADAT Bridge
I/O is auto power-selecting (100V-240V)
and will work with a standard modular ca-
ble when connected to AC power recepta-
cles in any country.
Primary Connections for
All Systems
Connecting the ADAT Bridge I/O to
Pro Tools and ADAT
This section covers the basic connections
between the ADAT Bridge I/O, your
Pro Tools system and ADAT:
• ADAT
Optical
connections between the
ADAT Bridge and your ADAT(s).
•
Audio Interface
connections between the
ADAT Bridge I/O and Pro Tools.
•
Clock
connections.
• (Optional:)
Audio
connections from the
ADAT Bridge I/O to a monitoring system.
It is important that you establish basic
ADAT Bridge I/O system connections be-
fore putting together a more complex con-
figuration. Refer to the basic system setup
instructions that follow to configure and
test the essential portion of your system.
Then refer to the larger system setup in-
structions that apply to your particular stu-
dio setup and configure those additional
pieces of equipment.
