The E-MU Sync Card (Optional Accessory)
The Sync Card provides Word Clock in and out, SMPTE (LTC) in and out and an additional MIDI output for transmitting MIDI
Time Code (MTC). MIDI Time Code is a special rendering of SMPTE that can be transmitted over MIDI cables.
Word Clock is a standard means of synchronizing two or more pieces of digital equipment at the system sample rate
(44.1kHz, 48kHz or 96kHz). 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).
Connections
Word Clock Inputs
and Outputs
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.
SMPTE In/Out
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.
MTC Out
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.
