I am the original owner. I used this DEQ2496 for one project and it has been racked in my smoke-free studio ever since. The original English and German owner's manuals are included. Note the superficial scratches from when the unit was racked. I took close-up photos of all of them, and they are the only reason I downgraded the condition to “very good”. The video shows me paging through the various functions, demonstrating that the unit is working. The original covers to the optical ports are with the unit. You probably know all about this unit, but, if not, it's an extremely versatile processor, combining graphic, parametric, and dynamic EQ, compression/expansion, feedback attenuation, stereo imaging, very flexible IO, and more. One of the most surprising features, which I found very useful, was the RTA. It shows you the strength of each frequency across the audio spectrum.
