Every input and output tested and working on this Digidesign 003 Rack+ Audio Interface, modified by Black Lion Audio for exceptional audio quality. BLA signature mod. With 8 mic pres and 8 line inputs, this FireWire interface is in amazing condition! The original box is included. Power supply and firewire cable included as well. Will ship with knobs removed and bagged to avoid damage. The interface is currently working with my 2018 Macbook Pro on Monterey using these Neyrinck drivers: https://neyrinck.com/downloads/digihelper/
