Azimuth Co-ordinator

The Azimuth Co-ordinator was the first panning control for a quadraphonic sound system, at that time a new concept.

The system was operated using two joysticks, which allowed an audio signal to be panned between up to six loudspeakers placed around the hall.

During Pink Floyd's live shows, the Azimuth Co-ordinator was operated by keyboardist Rick Wright.

It was constructed by technical engineer Bernard Speight at EMI Recording Studios.

Lost for many years, it was found under the aegis of London's Victoria and Albert Museum, and displayed as part of their Theatre Collections gallery[1] from March 2009.
