This is the original, fully-original Urei 1620. It's the rarest early model, a 600-series. The rotary faders have good torque, and it has never been used at a DJ event. I purchased it about 20 years ago from a specialist shop in Tokyo. I connected it to a turntable for the listing, and it's working without any problems. The sound quality is excellent, as you'd expect from Urei. The front panel is also generally clean. It seems to be in good condition, but please understand that this is vintage equipment, and no returns are accepted. - Model: 1620 - Brand: Urei Rotary Mixer Thank you for looking.
