Behringer A800 stereo power amplifier. It has a maximum output of 400W x 2 (4 ohms). It's quite high-performance compared to their A500, and I think it's a power amplifier with a very good cost performance. Please refer to the following for details. https://otaicuoshop.com/?page_id=1466 I was using it in my home studio until just before, so I don't think there are any functional problems, but there are some minor scratches on the exterior, so I would appreciate it if you could check them in the photos. I am selling it because I am replacing my equipment. A power cable is included. Thank you.
