Awesome little interface with dual headphone jacks, 4 trs/xlr dual input preamps, two sets of monitor ouputs, and midi in/out. its been a great unit but im upgrading to something with more mic inputs. Original box, paperwork, ac adaptor and usb c cord are all included. (it can run on power from ac adaptor or just usb power from computer). im pretty firm on price but id consider trades for guitar stuff, keys, or other recording gear.
