This is a Lexicon PCM 90, a renowned reverb unit. It shows signs of use, and the display has some clouding and dirt due to aging. Please refer to the photos. It works without issue, but occasionally an error occurs during startup, which can be resolved by restarting the power. When the error occurs, the top red light on the input level meter stays on, and no reverb sound is produced. Once it starts up correctly, it operates without problems. The startup error did not occur during the check before listing. Also, I mainly used it for editing presets on the fly, and I haven't used the memory or detailed editing functions, so I haven't checked those features. I also do not own a memory card. Considering the above points, I am selling this as junk. The sound quality is superb and silky, incredibly pleasing, and of a quality that justifies its reputation as a dedicated, legendary unit, completely different from plugins. It has a real, comfortable feel that is completely different from those found in digital mixers or plugins. It is also a 100V specification for domestic use in Japan. (Please check the photo of the top panel.) Only a third-party power cord (3-pin type) is included. It will be carefully wrapped in air padding, placed in a cardboard box, and shipped. I am also listing this on other platforms, so please be aware that I may remove the listing if it sells elsewhere.
