Word Clock
Mbox 2 Pro provides Word Clock In and Out
connectors on the back panel that let you syn-
chronize, or “clock” Pro Tools LE and
Mbox 2 Pro to industry standard Word clock.
Word clock is used to synchronize a wide range
of devices such as non-linear video systems and
other types of equipment typically found in pro-
fessional audio facilities.
With both Word clock input and output, your
Mbox 2 Pro-equipped Pro Tools LE system can
act as Word clock “slave” or “master.”
To connect Word clock to Mbox 2 Pro:
Using high-quality, 75 ohm BNC cables (not
included) connect the Mbox 2 Pro Word Clock
In and Out connectors to the appropriate ports
on the other Word clock-capable devices in your
studio.
Using Word Clock with
Pro Tools LE
Pro Tools LE with Mbox 2 Pro can act as Word
clock master, or as a slave to Word clock sup-
plied by an external device.
Pro Tools LE as Word Clock Master
Mbox 2 Pro Word clock output is always active,
letting Pro Tools supply Word clock to any con-
nected devices that support standard Word
clock.
To use Pro Tools LE as Word clock master:
1
Make sure all connections are correct between
Mbox 2 Pro and your external devices.
2
Configure all external devices to slave to the
Word clock coming from Mbox 2 Pro. (Be sure to
verify sample rate settings, termination require-
ments and other internal settings for the device;
refer to the manufacturer’s documentation if
you need more information on the particular re-
quirements for your other equipment.)
