M-AUDIO's ProFire 610 audio interface with 6 inputs and 10 outputs, MIDI connectivity. I was using this for production until recently, but I'm selling it due to a change in equipment. It can be powered via bus power, so no adapter is needed, and it's great for studio work. High sound quality, low latency, and phantom power supported. Connection is FireWire 400. I only used the main unit, so all bundled software and accessories like cables are unused. The main unit has scratches. The cushion rubber on the bottom has been re-attached.
