Overall in good working order except that the talkback mic does not work. All other inputs and outputs are functioning properly. There is some wear and tear on the finish as seen in the photos. I used this as my the monitor controller in my home studio until recently. The big knob has a nice feel to it, but I didn't need all the features. I ended up swapping it with something that takes up less space on my desktop.

This is Revision C03 of this model.
