Q-File
Why Q-File?
The title Q-FILE aptly describes an extremely versatile stage and studio lighting control system in which "cues" (i.e. lighting changes) are "filed" (i.e. memorised) during rehearsal. These cues may then b repeated during a production with supreme ease and accuracy.
Through this use of modern electronic technology, the whole process of planning and using theatrical lighting becomes an "armchair" exercise. Even the most ambitious lighting changes can be initiated by the operation of no more than two push buttons.
excerpt from the Q-file manual, (1975)
“At the University, there was an early electronic memory lighting console named the Q-File. It didn’t actually run a program, just a logic ladder machine. In 1973, when installed, it cost $150,000. I took my brother to look at this. He said, ‘Gack! We can do this for $5,000.’” - Fred Foster
