 The EMT 250 mobile reverberation unit in particular, designed in 1974 by freelance industrial designer Peter Bermes for EMT in close cooperation with EMT Technical Director Karl Otto Bäder and MIT Professor Barry Blesser, who had developed and patented the unit's digital algorithm, quickly gained a solid reputation primarily among west coast's recording studios in the US, due to its unrivalled sound quality and being nicknamed 'R2D2' because of its iconografic lever controlled interface, or 'Spaceheater' due to its vertical heat sink body made of black anodised aluminium panels and separate U-shaped 'Chimney', housing all heat-emitting ic's and therefore being painted red.Because of its unique sound and design qualities, the EMT 250 was selected as a permanent entry to the collection of the 'TEC Hall of Fame' in 2007.Then the company moved its headquarters in a completely new, 35,000-square-meter factory with a tidy two-storey building in Kippenheim, Wilhelm-Franz-Strasse 1.
