Prototype Online: Bob Casey spins double disks

July 25, 2013

At a sock hop in 1958 Bob Casey used two turntables to play music for the crowd.  His system is credited with being the first double-decked audio-system used by a disc jockey. The two turntables, as well as the individual volume controls and early crossfader, allowed for a seamless transition between songs. These innovations are now standard in modern DJ audio systems. In this interview Bob Casey describes his inspiration for the system, its debut, and its impact on future DJ’s.
