It's in rough shape, but it's a working 16 channel multitrack usb audio interface and mixer. Lots of inputs and outputs, two effects sends, and channel inserts. The bottom metal is bent so I could get the circuit board out for cleaning with DeoxIT, some of the knobs were noisy. Visually though you can't see the bend when looking down at the mixer and it doesn't affect its rigidity. Some yellowing on the white knobs. I also 3D printed some button extenders so the recording buttons would work. Message beforehand if you would like a signature upon delivery or if you have any questions
