SMPTE Trigger while Locking to an Unresolved
Source
SMPTE Trigger can be used with an optional
SYNC peripheral or equivalent Digidesign-qual-
ified device to resolve Pro Tools recording and
playback speed while slaving to LTC. This en-
ables long-term, accurate synchronization by re-
solving to any variations in incoming time code.
SYNC peripherals also support VITC and Bi-
phase/Tach positional reference.
SYNC Peripheral Synchronization
Options
By adding a Digidesign Synchronization periph-
eral to your Pro Tools|HD system, you can use
Pro Tools as the master device in your synchro-
nization setup. All other devices are then slaved
to Pro Tools.
You can use Pro Tools in conjunction with a
Synchronization peripheral to generate LTC,
MIDI Time Code, or MMC commands. When
the SYNC peripheral is reading incoming SMPTE
time code, it regenerates the time code through
the LTC or MTC output connector. This signal
can be passed along to other slave devices.
MachineControl™
Digidesign Synchronization peripherals also
support Digidesign MachineControl software,
which provides many specialized features for
post production synchronization tasks includ-
ing remote track arming, VTR emulation, serial
time code, and other capabilities. (See the Ma-
chineControl Guide for more information, or con-
tact your Digidesign dealer.)
Ext. Clock Output
Pro Tools can be used as the master device in
your synchronization setup, where all other de-
vices are then slaved to Pro Tools Word Clock
output.
With Pro Tools|HD systems, clock output can be
configured for 1x Word Clock, or 256x Slave
Clock for Digidesign Legacy audio interfaces
(such as the 888|24 I/O).
To set Ext. Clock Output:
1 In Pro Tools, choose Setup > Hardware.
2 Click the Ext. Clock Output pop-up menu and
select an available signal.
3 Click OK to close the Hardware Setup dialog
when you have finished.
Session Setup Window
The Session Setup window lets you configure
various time code-related settings on your sys-
tem. The window also includes display-only ar-
eas for session sample rate, file format, bit
depth, and pull up and pull down rates.
For instructions on connecting an external
synchronization peripheral to your Pro Tools
system, refer to your Setup Guide. If you are
using a SYNC peripheral, refer to its docu-
mentation.
For more information on configuring
Legacy audio interfaces, see the
Pro Tools|HD Setup Guide.
If the Legacy Port is enabled (as opposed to
the Expansion Port) then the Ext. Clock
Output automatically switches to
Slave Clock.
Pro Tools LE systems with Complete
Production Toolkit or DV Toolkit 2 support
various time code–related settings (such as
Time Code and Feet+Frame Timebase
rulers). For a complete list, refer to the
Complete Production Toolkit Guide or the
DV Toolkit 2 Guide.
