a dedicated SMPTE output connector
Connections
If the connected device can directly output SMPTE timecode, use an
audio cable to connect the output to the TIME CODE INPUT—SMPTE
connector on the back of the 02R.
If the connected device does not have a dedicated SMPTE output
connector, record the timecode onto a spare track (in the case of a
multitrack recorder) or a special track (in the case of a video recorder or
film post-production recorder) and connect the output from that track to
the timecode input connector on the 02R.

Using MIDI Timecode (MTC)
MTC is a MIDI System message that indicates absolute time in
hours:minutes:seconds:frames, in the same fashion as SMPTE. MTC is an
alternate method of transferring the timecode data from one device to
another.
Use MTC when you want to synchronize an 02R automix with MIDI
sequencers or a multitrack recorder that has MTC output jacks. Use a
MIDI cable to plug the MTC output connector of the controlling device
into the TIME CODE INPUT—MTC connector on the back of the 02R.
The 02R can use the MTC or MIDI IN jack to receive MTC, and the first
jack to receive MTC takes priority. While MTC is being read from the
