The Digi 002 Rack featured eight balanced analog inputs and eight balanced analog outputs. Digidesign outfitted the first four of the inputs with mic preamps and 48V phantom power. Two switches controlled phantom juice for the mic inputs in pairs. The mic inputs had a maximum input level of +3 dBu and the line inputs had a maximum input level of +18 dBu. The Digi 002 Rack had an I/O frequency response from +0.15 to -0.5 dB and 20 Hz to 20 kHz. The mic-preamped inputs had an A-weighted dynamic range of 101 dB and the other four inputs had a dynamic range of 108 dB. The unit also had an RCA "alternate source" input that allowed the user to monitor external sources, from reel-to-reel players to CD players. The first four outputs were monitor outputs with a dynamic range of 112 dB. The first two outputs had additional quarter-inch TRS and RCA connectors. The last four outputs had a dynamic range of 114 dB, and the alternate outputs had a dynamic range of 98 dB.
The Digi 002 Rack came with one Firewire port, one MIDI input port and two MIDI outputs ports. Users could choose between eight channels of ADAT optical inputs and outputs and two channels of S/PDIF.
The Digi 002 Rack recorded both analog-to-digital (A-D) and digital-to-analog (D-A) signals with a bit-depth of 24 at 44.1-, 48-, 88.2- and 96-kHz sample rates.
The Digi 002 Rack came with an in-depth, 153-page "Getting Started" manual.
Because of its slim, mountable design, replacing a desktop mixing board with the Digi 002 Rack could save space in a home studio. The Digi 002 Rack came with a lightweight version of Pro Tools multi-track recording software. This allowed the home user to send intact project files to Pro Tools-based professional studios and mastering houses for additional sweetening sessions, mixing and mastering.
Unlike the original Digi 002, the Digi 002 Rack had no hardware control surface. Users could use software-based sliders within Pro Tools LE to control levels and record mixing automation.
