higher) or Sync Mode (Pro Tools 5.2 and lower)
to match the type of input.
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.

nize to it. If your input device is not powered
on, leave the Clock Source set to Internal.
