When recording or monitoring, Pro Tools can
synchronize to an external clock source. Op-
tions for external clock vary according to the
type of Pro Tools system you are using.

Pro Tools can receive external clock from the
Optical input or S/PDIF input.
To select an external clock source for a Digi 002
or Digi 002 Rack system:
1 Choose Setup > Hardware.
2 Set the Clock Source to match the type of in-
put.

3 If you choose Optical, make sure the Optical
Format matches the type of optical input you
are sending to your Pro Tools system.

If you set the Optical Format to S/PDIF,
Pro Tools will watch the Optical port for ex-
ternal clock, and ignore any clock input on
the S/PDIF RCA jacks.
