Smpte Time Code Sync Connections - MOTU micro express User Manual

SMPTE TIME CODE SYNC CONNECTIONS

Your MOTU MIDI interface is both a SMPTE time code
converter and generator. As a converter, it locks (slaves) to
incoming longitudinal SMPTE time code (LTC) and
converts it to MIDI Time Code (MTC) and reshaped LTC.
As a generator, it produces both LTC and MTC time code,
either running under its own internal clock or while slaved
to external time code (or other time base).
When making the SMPTE time code connections
described in the following sections, do not pass the signal
through any type of signal processing equipment. Use
shielded quarter-inch audio cables.
For a complete explanation of synchronization, see
chapter 8, "Synchronization" (page 113).

Connecting a SMPTE time code source
Connect any SMPTE time code source, such as the SMPTE
timecode track on an analog multitrack tape deck, to the
SMPTE IN port on your MOTU MIDI interface as shown
in Figure 2-5. (For information about recording time code
tracks, see "Striping SMPTE" on page 118.)
