ADAT Bridge I/O

10

continuously active on the AES/EBU jacks,

carrying audio routed to outputs 1–2 in

Pro Tools.

7. S/PDIF In/Out

These are unbalanced, two-conductor RCA

jacks that accept and output a 24-bit

S/PDIF digital data stream. Output is con-

tinuously active on the S/PDIF jacks, carry-

ing audio routed to outputs 1–2 in

Pro Tools. To avoid RF interference during

S/PDIF transfers, we recommend that you

use 75 ohm coaxial cable and don’t exceed

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 256x Super Clock

signal for slaving additional ADAT Bridge

I/Os, audio interfaces, or synchronization

peripherals.

The Slave Clock In jack is a standard BNC

connector designed to receive a 256x Super

Clock signal from another ADAT Bridge

I/O, another Digidesign audio interface, or

a synchronization peripheral that passes

Slave Clock, such as the USD. Because cru-

cial 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 be-

tween 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 that 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

(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 devices.

Optical Connections

Quick Connections

◆

For One ADAT:

• ADAT Bridge Optical #1 Out to ADAT

#1 Optical Input.

• ADAT Bridge Optical #1 In to ADAT #1

Optical Output.

◆

For Two ADATs:

• Other connections are same as instruc-

tions for one ADAT, but adding ADAT

Bridge Group B Optical In/Out to

ADAT #2 Optical Out/In.
