This is the older one BEFORE the USB "C" version replaced it. This thing has been awesome for my home studio. I got it during COVID I think. You can record the live mix directly to an SD card without even turning your computer on - great for band practices. There are some built-in FX and you can run two monitor mixes. It's also a full-on Audio Interface so you can hook it up to your computer and multi-track into your favorite DAW (Cubase, Pro Tools, Logic, Reaper, etc.). I've sort of "cross-grading" to a hybrid analog console + interface setup, so I no longer need the mixer utility of this unit. For most home studios, this thing is more than you need. My studio is mostly smoke free less some of my friends' 420 moments. Otherwise, it's just been mounted in my DIY studio desk for around 4 years or so. I have the original sides as well as the rack ears for it.
