Syncing To Smpte Time Code - MOTU Traveler User Manual

SYNCING TO SMPTE TIME CODE

The Traveler system can resolve directly to SMPTE
time code. It can also generate time code and word
clock, under its own clock or while slaving to time
code. Therefore, the Traveler can act both as an
audio interface and digital audio synchronizer, to
which you can slave other digital audio devices.
You can use the Traveler to slave your audio
software to SMPTE as well, as long as your software
supports sample-accurate sync, which is the means
by which the software follows the Traveler. The
accuracy may not be sample-accurate, but in most
cases it will be very close.

Use this setup if you have:
✓
A SMPTE time code source, such as a multitrack tape deck.
✓
A Traveler by itself, OR with another slaved device (such as a
digital mixer).
✓
Host software that supports sample-accurate sync.
This setup provides:
✗
No sample-accurate locating.
✓
Continuous sync to SMPTE time code.
✓
Sub-frame timing accuracy.
✓
Transport control from the SMPTE time code source.
Choose SMPTE as the clock source in
AudioDesk, Digital Performer, or the MOTU FireWire
Audio Console. This setting can also be made in the
MOTU SMPTE Console (shown below).
Launch the MOTU SMPTE Console to specify the time code input,
frame rate and amount of freewheel. Also, confirm that the Clock
Source/Address is SMPTE/SMPTE. For details about the other
settings, see chapter 12, "FireWire SMPTE Console" (page 87).
