MOTU SMPTE SETUP

SETTING UP FOR SMPTE TIME CODE SYNC

In summary, the 8pre system can resolve directly to

SMPTE time code. It can also generate time code

and a time base, under its own clock or while

slaving to time code. Therefore, the 8pre can act

both as an audio interface and digital audio

synchronizer. You can use the 8pre 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 8pre.

The accuracy may not be sample-accurate, but in

most cases it will be very close.

Choose SMPTE as the clock source in AudioDesk, Digital

Performer, or the MOTU Audio Setup. This setting can also be

made in the MOTU SMPTE Setup (shown below).

Host software that supports sample-accurate sync.

This setup provides:

✗

No sample-accurate locating.

✓

Continuous sync to SMPTE time code.

✓

Sub-frame timing accuracy.
