Syncing To Smpte Time Code - MOTU UltraLite- mk3 User Manual

SYNCING TO SMPTE TIME CODE

The UltraLite-mk3 system can resolve directly to
SMPTE time code. It can also generate time code,
under its own clock or while slaving to time code.
Therefore, the UltraLite-mk3 can act both as an
audio interface and as a SMPTE time code
synchronizer to which you can slave other devices.
You can use the UltraLite-mk3 to slave your audio
software to time code as well, as long as your
software supports sample-accurate sync, which is
the means by which the software follows the
UltraLite-mk3. The accuracy may not be sample-
accurate, but in most cases it will be very close.

First, choose SMPTE as the clock source
in AudioDesk, Digital Performer, or
MOTU Audio Setup. This setting can
also be made in the MOTU SMPTE
Console (shown below).
SMPTE time code source
UltraLite-mk3 interface
Use this setup if you have:
✓
A SMPTE time code source, such as a multitrack tape deck.
✓
An UltraLite-mk3 by itself, OR with another slaved device
(such as a digital mixer).
✓
Host software that supports sample-accurate sync.
This setup provides:
✓
Continuous sync to SMPTE time code.
✓
Sub-frame timing accuracy.
✓
Transport control from the SMPTE time code source.
In AudioDesk or Digital Performer:
1. Choose Receive Sync from the Setup menu.
2. Choose the Sample-accurate option. (If this
option is grayed out, choose SMPTE as the
clock source setting first, as shown above.)
3. Make sure that Slave to External Sync mode
is enabled.
Launch the MOTU SMPTE Console to specify the time code frame rate and amount
of freewheel. Also, confirm that the Clock Source/Address is SMPTE/SMPTE.
