It is equipped with a set of sliding matrix switches above each module; these switches are the primary method of interconnecting modules.
There are rows of 1/8" miniphone jacks at the end of each row of matrix switches,[1] to interconnect rows of switches. The main 2500 cabinet can hold 15 modules, and optional wing cabinets can each hold 8. The matrix switch interconnection scheme allow any module's output to connect to any other module's input. Unlike the patch cords of competitive units from Moog and Buchla, which can obscure control knobs and associated markings, the matrix implementation enables a cable-free experience but at the price of greater cross-talk.[2]
Although the 2500 proved to be a reliable and user-friendly machine, it was not commercially successful, selling approximately 100 units.[3] A collection of the 2500's most popular modules was packaged into a single, non-modular unit as the ARP 2600, leaving out the matrix switching and more esoteric functions.
John Kongos first used one at Trident Studios in 1971, then in 1973 he acquired his own - it was used extensively at his Tapestry Studio, on his own recordings as well as Def Leppard (Pyromania), Mutt Lange, Alain Chamfort, Tony Visconti, Ryan Ulyate and many others.
In 1972 Pete Townshend of the Who used an ARP 2500 on the Who's Quadrophenia.[4] Townshend built his own home studio to experiment and record, due to the enormous amount of time he spent creating his groundbreaking synthesizer orchestrations on both Quadrophenia, and the movie version of Tommy.
The ARP 2500 was extensively used by British producer David Hentschel on recordings such as "Funeral for a Friend" from Elton John's 1973 album Goodbye Yellow Brick Road. Jeff Wayne's 1978 multi-platinum selling album War of the Worlds features the ARP 2500, including the sound of Martian speech.
In the 1977 motion picture Close Encounters of the Third Kind,[5] a 2500 unit is used to communicate with aliens. Phil Dodds, ARP's Vice President of Engineering, was on set to install and manage the synthesizer; Steven Spielberg, liking his looks, cast him on the spot as an extra to play the 2500. The unit featured in the film consisted of a fully loaded main unit, two fully loaded wing cabinets and dual keyboards in a custom case.
It has been used by artists such as Aphex Twin, David Bowie, Vince Clarke, Ekseption, Faust, John Frusciante, Jean Michel Jarre, Cevin Key,[6] Kraftwerk, Jimmy Page, Vangelis and the Who. The composer Éliane Radigue has worked almost exclusively with the 2500.
