The reference signal must always be present and stable, and it must be within 4% of the
chosen sample rate for the current directory. (46080-49920 Hz. for 48K, 42336-45864 Hz for
44.1.) Note that some older Shortcut units do not support frequency measurement and
therefore will not detect that the sample rate is out of specification.
The signal is often the same signal that is used to input digital audio to the Shortcut, such
as a buss or master output from a digital mixing console, the audio input feed from a router or
an output of the digital multi-track. Any constant AES format digital audio signal that is
derived from the master or house sync can be used. Shortcut cannot directly sync to word clock
or video references.
The digital audio input used by the External Sync (and D-NET Echo) is selected
independently of the audio input used for recording. To select this input:

To set Shortcut to use an external reference:

3. Use the Arrow keys or the Scrub Wheel to select either EXTERNAL or
INTERNAL.
4. Press E
If the external reference signal is missing or bad, the S
message "(SYNC INPUT BAD)" will be shown in the top line of the display. It is not
possible to play or record while the unit is in this condition. When the correct signal is applied
the unit will automatically lock to it and clear the error displays.
Note that when recording using the digital inputs, sync is always derived from the digital
input being recorded, even if it is not the one selected for external sync. This only presents a
problem when recording from a device that is not sync'ed to the sample rate of the monitoring
system. During the recording, the connection from the Shortcut digital output to the monitoring
system will not be locked to the sync reference. The recording itself will be unaffected and will
sound perfect on subsequent playback. Once the recording is finished, the sync reference will
return to the external reference input for playback.
All other operations are the same as when using internal sync.
