Digi 001 Quick Start Guide 36
To connect a digital audio source:
1 Connect an ADAT or S/PDIF format optical device to the Optical In on the Digi 001 PCI
Card, or connect an RCA S/PDIF device to the RCA connectors on the back of the
Digi 001 I/O Box.
▲ You can only use one pair of S/PDIF inputs (either RCA or optical) at a time.
▲ The next step is only required if your device requires Pro Tools LE to sync to it.
(In most cases, it is more desirable for a device to sync to Pro Tools LE.) This
might be the case if you are recording from an Optical or S/PDIF device. Read
your device’s documentation for more information.
2 In Pro Tools LE, select a Sync Mode. Choose Setups > Playback Engine and select Optical
or S/PDIF (RCA), depending on where you connected your digital device.
3 If you are using the optical input on the Digi 001 PCI Card, click Other Options and
select the correct Optical Input Format (ADAT or S/PDIF).
