Abstract
A non-contact fader control uses a movable permanent magnet and one or two Hall-effect sensors to provide a constant, direct current voltage output. Signal conditioning and digital control circuitry linearize the output and otherwise precondition the output for application to a voltage controlled amplifier for the control of audio output in an audio mixing board.
