This setting determines the clock mode for your Express 
interface. The choices are:
Internal
The Express interface operates under its own clock and 
ignores incoming time code.
MTC
Allows your Express interface to sync to MIDI Time Code 
from another device. For complete details, see “MTC 
Mode” on page 63.

Allows your Express interface to sync to SMPTE time code 
received on its SMPTE input jack. This mode provides 
more features than LTC QuickLok mode, such as the 
ability to regenerate time code via the SMPTE output jack.
