Azimuth co-ordinator

From Wikipedia, the free encyclopedia

The Azimuth coordinator was the first quadraphonic sound system. Pink Floyd became the first band to use it in their early shows.

The Azimuth coordinator was a multi-speaker pan pot system. It used four large rheostats housed in a large box, converted from 270 degrees rotation to 90 degrees. The system was operated by a joystick, which allowed the sound to be panned around the hall.

The Azimuth coordinator was operated by keyboardist Rick Wright.

The original one was stolen after the first concert in Queen Elizabeth Hall in London, England. A second system was built for the concert at the Royal Festival Hall in London on April 14, 1969. The second one had two pan pots and four channels.
