ADAT Bridge I/O

◆
Two ADATs:
• Same as instructions for one ADAT, but
using ADAT Bridge Group B Optical
In/Out and ADAT #2 Optical Out/In.
If you use a BRC or other device to synchro-
nize your ADATs, refer to “Synchronization
Connections” on page 16 for additional in-
structions on integrating the ADAT Bridge
I/O into your system.
The following sections provide optical con-
nection instructions for systems with one
or two ADATs.
▲
If you connect a fiber optic cable to the Op-
tical Out of the ADAT or ADAT Bridge I/O while
it is on, you will see a red light at the other end
of the cable. This is not a laser, so it will not
damage your eyes.
To make optical cable connections between
the ADAT Bridge I/O and your ADAT(s):
1
Connect one of the fiber optic cables
(provided with the ADAT Bridge I/O) to the
jack labeled Optical #1 Out on the Digide-
sign ADAT Bridge I/O, and connect the
other end to the Digital Input on your pri-
mary (master) ADAT. Avoid touching the
ends of the cable to prevent oils from your
skin from getting on the lenses.
2
Connect the second fiber optic cable to
the jack labeled Optical #1 In on the
Digidesign ADAT Bridge I/O and attach the
other end to the Digital Output on your
ADAT.
3
If you are using two ADATs with your
ADAT Bridge I/O (16-channel mode), make
the same In/Out connections from the Op-
tical #2 In/Out ports on the Digidesign
ADAT Bridge I/O to the Digital In/Out ports
on ADAT #2.
About ADAT Sync 9-pin
Also shown in the above diagram is the
ADAT 9-pin sync cable (from the master
ADAT Sync Out to the slave ADAT Sync In),
required for proper clocking between your
ADATs. Your ADAT User’s Guide assumes
that if you have two ADATs you already
have their Sync cables connected in this
