After a Digital Transfer
After you have finished recording digitally, set
the Clock Source pop-up menu in the Session
Setup window back to Internal. Otherwise,
Pro Tools will not switch back to its own inter-
nal clock and may not record or play audio
properly. Failure to switch back to Internal syn-
chronization typically results in pitch problems
(fast or slow playback), clicks and pops, or DAE
errors, since a DAT machine or CD Recorder that
is idle can default to a different sample rate or
stop outputting a sample rate clock altogether.
Some Digidesign I/O units only have two
channels that can be set for analog or digi-
tal. For example, Mbox 2 has S/PDIF L–R
(Stereo) digital inputs and In 1–2 analog in-
puts. Mbox 2 can record through analog
and digital inputs simultaneously.
