Abstract: An operating device (1) having an illuminated level control actuating element, in particular for audio systems, comprising a level control (10) which has an actuating element (40) movable along an adjustment path (20). In the interior, the actuating element (40) comprises a light guiding section (160) by which light coupled into a coupling section (130) on the lower side face of the actuating element (40) is guided to one or more exit zones (170) of the gripping faces (60) of the actuating element (40), and a plurality of illumination means (100) which are controllable for individual positioning are arranged along the adjustment path (20), such that in any position of the level control (10) along the adjustment path (20) the actuating element (40) covers at least one of the illumination means (100) with the lower side face of the actuating element.

Abstract: A mixer carriage for an audio, video and/or lighting control console contains a tray body with a tray surface and a coupler for movable coupling to the audio and/or video and/or lighting control console, so that the mixer carriage is moveable relative to a user interface of the audio, video and/or lighting control console. The tray body has at least one lighting device on it for illuminating the tray surface.
