5 Select Store Current Program in the Stu-

dio 64XTC menu to save the settings.

In Pro Tools:

6 In the Peripherals/Synchronization win-

dow select “Generic Device” in Synchroni-

zation and “Studio 64 XTC” for Port.

7 At the top of the Peripherals dialog, click

the Machine Control button to open the

Machine Control Peripherals window.

There, enable Machine Control (at the bot-

tom of the window) and for “Send to” se-

lect ADAT (this is the device/port you just

deﬁned in OMS Setups) and set its ID to

127.

8 Click OK to close the Peripherals dialog.

9 Once configured in this way, the 64XTC

will receive transport commands from

Pro Tools via MMC and send those com-

mands to the ADAT via OMS and the

64XTC. The 64XTC then converts that into

ADAT Sync, which it sends to the ADAT via

the 9-pin connection. The 64 XTC is pro-

viding the master clock reference to

Pro Tools via 256x (Slave Clock) connec-

tion as described in “Setup E: Synchroniz-

ing Pro Tools and ADAT using an

Opcode Studio 64XTC” on page 22.

Using the ADAT Bridge I/O

in Stand-Alone Mode

In addition to its role as a bridge between

Pro Tools and ADAT, the ADAT Bridge I/O

can also be used on its own as a stand-alone

S/PDIF or AES/EBU-to-ADAT-optical con-

verter. This capability allows you to digi-

tally transfer audio from DAT or a digital

I/O-equipped CD player or digital mixing

console to ADAT without having to power

on your computer or launch Pro Tools.

Audio received over the ADAT Bridge I/O’s

digital ports can be monitored with 20-bit

fidelity through its analog outputs. These

outputs default to -10 dBV operating levels

when the ADAT Bridge I/O is used in stand-

alone mode.

To use the ADAT Bridge I/O in stand-alone

mode:

1 Make sure that your computer is off.

2 Connect the digital audio source (the

DAT or digital I/O-equipped CD player) to

the ADAT Bridge I/O.

3 Turn on the digital audio source (the DAT

or digital I/O-equipped CD player).

4 Turn on the ADAT Bridge I/O.

5 The ADAT Bridge I/O will scan both its

S/PDIF and AES/EBU ports for word clock.

Once word clock lock has been achieved,

the ADAT Bridge I/O will switch to digital

sync mode and automatically match its

sample rate to the incoming data. (If the in-

coming word clock is 48 kHz, the 48 kHz

sample rate LED will remain lit. If the in-

coming word clock is 44.1 kHz, the 48 kHz

sample rate LED will ﬂash.) Accordingly,
