A type of connector used to convey gate signals in early Moog synths. The Cinch-Jones connector resembles a mini version of a two-prong U.S. power plug; the body is a cylinder about 1/2" (1.25 cm) in diameter, with two parallel flat-bladed pins. Moog synths which use the Cinch-Jones connector also use the S-trigger format for gate signals, which is not compatible with conventional gate or trigger signals. However, adapters can be purchased or easily made.
There are actually a range of Cinch-Jones connectors with different configurations of pins. Only the two-pin type was used by Moog. The Cinch-Jones connectors are still being manufactured and readily available as of August 2015.
