“Sequential Circuits SCI ProFX Rack System w/ 3U Expansion Cage Rack Unit. Extremely rare 500-series format rack system manufactured very briefly between 1983-1984. This package consists of the MODEL 500 System Controller w/ 3U rack bay. MODEL 512 Distortion module, MODEL 514 4×2 Mixer, MODEL 524 Digital Delay module and 3U Expansion Bay Rack Unit. System controller and all units power on. Being sold as-is due to not being able to properly program it without the proper instructions. There may be issue with the digital delay module as it appears ‘stuck’ and its display will not react to any of the controls. Was instructed by a former Sequential Tech in performing a system reset which did nothing. Otherwise in excellent cosmetic condition. Rear plate for the distortion module appears to be missing. Comes with 2 loose plate blanks with no screws. Also comes with a pair of sequential circuits branded bypass/tap expression switches. Comes with main power cable. ” Click here to search for synths on eBay
