Syncing To Video And/Or Smpte Time Code Using A; Synchronizer - MOTU 828mkII User Manual

SYNCING TO VIDEO AND/OR SMPTE TIME
CODE USING A SYNCHRONIZER
If your host audio software does not support the
828mkII's on-board SMPTE sync features
(because your software does not support sample-
accurate sync), you need a universal synchronizer,
such as a MOTU MIDI Timepiece AV or Digital
Timepiece. These dedicated sync boxes can read
video and SMPTE time code and then convert it
into word clock and MIDI Time Code (MTC). The
word clock goes to the 828mkII to resolve the audio
hardware, and MIDI Time Code is fed to your host
audio software, which locks to it, as shown below
in Figure 3-15.

Figure 3-15: If your host audio software does not support sample-accurate sync and the 828mkII's built-in
SMPTE sync features, use a universal synchronizer such as the MOTU MIDI Timepiece AV or Digital Timepiece.

Use this setup if you have:
✓
Video and/or a SMPTE time code source.
✓
A Digital Timepiece, MIDI Timepiece AV or other universal

synchronizer.

✓
Host software that does not support sample-accurate sync
(although you can use this setup even if it does).
This setup provides:
✗
No sample-accurate locating.
✓
Continuous sync to SMPTE time code.
✓
Sub-frame timing accuracy.
✓

Choose Word Clock In as the clock source in the MOTU FireWire
Audio Console application. If you have multiple interfaces
connected, be sure to choose the Word Clock In option that
corresponds to the interface receiving the clock signal.
