Abstract
An apparatus indicating the position of an adjustable lever, such as a control lever in a digital audio console, is described. A frame member constrains movement of the adjustable lever. The lever is operatively connected to an encoder apparatus, such that movement of the lever causes movement of the encoder apparatus to provide an indication of position of the lever within the frame member.
