Connectors on the Digi 001 PCI Card
The Digi 001 PCI Card installs in an available PCI slot in your computer. The PCI Card
includes optical digital I/O for 8 channels of ADAT I/O or 2 channels of S/PDIF I/O. The
card also includes a connector for the Digi 001 I/O Box.
Optical input
The optical input connects an optical digital audio source. This can be either an 8-channel
ADAT format audio source or a 2-channel S/PDIF audio source. The digital format that this
input accepts is switchable in Pro Tools LE. This connection provides up to 24-bit digital
audio for either format. This format uses a standard optical "lightpipe" cable. One optical
cable is included with Digi 001.
Optical Output
The optical output sends optical digital audio to a destination like a digital mixer or a
digital recorder. This can be either an 8-channel ADAT format destination or a 2-channel
S/PDIF audio destination. The digital output format is switchable in Pro Tools LE. This
connection provides up to 24-bit digital audio for either format. This format uses a
standard optical "lightpipe" cable. One optical cable is included with Digi 001.

Output Modes

Pro Tools LE software provides two different output modes, direct outputs and stereo mix
outputs. In Stereo Mix Outputs mode, each audio track or channel can be panned between
any pair of outputs (1–2, 3–4, 5–6, 7–8, etc.). By default, all tracks are routed to outputs 1–2.
This is the most common method used for stereo mixing.
In Direct Outputs mode, each track/channel is routed to a discrete output on the Digi 001
I/O Box. In this mode, no panning controls are available. This mode is often used to route
audio tracks to an outboard mixer, or to use outputs as sends (with inputs as returns) to
process audio with external effects.
