Syncing To Smpte Timecode - MOTU 828 Mk III Hybrid User Manual

SYNCING TO SMPTE TIMECODE

The 828mk3 system can resolve directly to SMPTE
timecode. It can also generate timecode and word
clock, under its own clock or while slaving to
timecode. Therefore, the 828mk3 can act both as
an audio interface and as a digital audio
synchronizer to which you can slave other digital
audio devices. You can use the 828mk3 to slave
your audio software to SMPTE as well, via sample-
accurate sync (if your host software supports it).

Use this setup if you have:
✓
A SMPTE timecode source, such as a multitrack tape deck.
✓
An 828mk3 by itself, OR with another slaved device (such as a
digital mixer).
✓
Host software that supports sample-accurate sync (such as
Cubase or Nuendo).
This setup provides:
✓
Continuous sync to SMPTE timecode.
✓
Sub-frame timing accuracy.
✓
Transport control from the SMPTE timecode source.
In Cubase, go to the Synchronization window and
choose ASIO Audio Device as the Timecode Base.
Launch the MOTU SMPTE Console and specify the SMPTE Source,
which is the interface receiving the SMPTE timecode. Also, confirm
that the Clock Source/Address is SMPTE/SMPTE. For details about the
other settings, see chapter 10, "MOTU SMPTE Console" (page 111).
