SMPTE Trigger while Locking to
an Unresolved Source
SMPTE Trigger can be used with a SYNC HD to
resolve Pro Tools recording and playback speed
while slaving to LTC. This enables long-term, ac-
curate synchronization by resolving to any varia-
tions in incoming timecode. SYNC HD also sup-
ports VITC and Bi-phase/Tach positional
reference.
SYNC HD Synchronization
Options
By adding a SYNC HD to your HDX or
HD Native system, you can use Pro Tools as the
master device in your synchronization setup. All
other devices are then slaved to Pro Tools.
You can use Pro Tools in conjunction with a
SYNC HD to generate LTC, MIDI Timecode, or
MMC commands. When the SYNC HD is reading
incoming SMPTE timecode, it regenerates the
timecode through the LTC or MTC output connec-
tor. This signal can be passed along to other slave
devices.
MachineControl
SYNC HD also supports MachineControl with
Pro Tools | Ultimate software. MachineControl
provides many specialized features for post pro-
duction synchronization tasks including remote
track arming, VTR emulation, serial timecode, and
other capabilities. (See the MachineControl Guide
for more information, or contact your dealer.)
Ext. Clock Output
Pro Tools can be used as the master device in your
synchronization setup, where all other devices are
then slaved to Pro Tools Word Clock output.
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.
For instructions on connecting a SYNC HD
to your Pro Tools system, see the SYNC HD
Guide.
