Pro Tools hardware interface. Connects using firewire but I have a thunderbolt adapter if needed. This unit is in good condition but you will need to do some research on what software version will work best - I haven't used it in a while.
Summary of features:
-Firewire connectivity.
-Eight analogue inputs and eight analogue outputs, all balanced.
-Inputs 1-4 have mic preamps with 48V phantom power, switchable in pairs.
-Eight channels of ADAT optical I/O or two channels of S/PDIF I/O.
-MIDI In and two MIDI Outs.
-A-D and D-A: 24-bit at 44.1, 48, 88.2 and 96kHz sample rates.
