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,
