Headphone Gain
This control allows you to adjust the output level of the headphone jack.
Headphone Output
Use the Headphone Output to connect stereo headphones. This jack accepts a 1/4" stereo
plug. This outputs any audio that is routed to analog outputs 1–2 in Pro Tools LE. The
Headphone Output is disabled in unpowered Monitor Mode (see “Monitor Mode” on
page 26 for more information).
Connectors on the Digi 001 I/O Box Back Panel
S/PDIF Digital I/O
The Sony Phillips Digital Interface Format (S/PDIF) is used in many professional and
consumer CD players and DAT recorders. The S/PDIF in/out jacks are unbalanced 2-
conductor phono (RCA) jacks that utilize a full 24-bit digital data stream. To avoid RF
interference, use 75-ohm coaxial cable for S/PDIF transfers and keep the cable length to a
maximum of 10 meters.
MIDI I/O
The MIDI connectors on the Digi 001 I/O Box allow Digi 001 to act as a MIDI interface. A
MIDI driver for this device is installed when you install Pro Tools LE, and recognized by
Windows Multimedia, or when you update MIDI Cards & Interfaces in OMS Setup
(Macintosh). One MIDI input and one MIDI output allow you to send and receive MIDI on
16 channels. These connectors accept standard 5-pin MIDI cables. Digi 001 MIDI I/O can
be used in addition to any other MIDI interfaces you are using.
Computer Connector
This connector is used to connect the I/O Box to the Digi 001 PCI card. The cable for this
is supplied with your system.
