8 - The E-MU Sync Daughter Card (optional)
The optional Sync Daughter card provides Word Clock in and out, SMPTE (LTC) in and out and an additional MIDI output
for transmitting MIDI Time Code (MTC). MTC is a special rendering of SMPTE that can be transmitted over MIDI cables.
Note: When the Sync Card is installed, MIDI 2 on the MicroDock is disabled. (MTC is using the MIDI port.)
Word Clock is a standard means of synchronizing two or more pieces of digital equipment at the system sample rate
(44.1kHz, 48kHz, 96kHz, or 192kHz). To avoid data corruption, digital equipment MUST be synchronized to each other.
Recording equipment can also be synchronized using SMPTE or MTC sync so that two audio recorders or an audio and
video recorder can lock together as a single machine. For more information, please refer to your Owner' s Manual (on CD).

16 - E-MU PCI Digital Audio System
Word Clock In: Receives word clock (sample clock) from another digital device such
as a digital video deck, digital recorder or digital mixer.
Word Clock Out: Sends word clock (sample clock) to another digital recorder. Word
clock is always output, whether it is generated by the internal clock or passed
through from the word clock input.
The SMPTE Input converts incoming SMPTE longitudinal time code (LTC) to MIDI Time
Code (MTC) and passes this information to the host computer to be used by a
sequencer or audio recorder application. When your computer application is the
"Master", MTC generated by the computer application is converted into SMPTE and
sent out to another SMPTE device such as another audio recorder to synchronize it
with the sequencer.
This output transmits MIDI Time Code to another computer or audio recorder. The
source of the MTC can be from the sequencer or SMPTE in.
