In 2004 ADB introduced WARP Profile - In this ellipsoidal profile spot conventional shutters have been replaced by four integrated blades controlled by a series of rings, each with 360⁰ endless rotation capability. Focus and Zoom settings are also controlled by a set of dedicated rings. The ring controls leave the exterior of the WARP spotlight with no protruding handles or levers. The design of the WARP allows the standard trunion arms to be replaced with a motorised yoke. This yoke links also into the ring controls providing automation of all other functions—focus and zoom, shutter insertion / rotation and gobo rotation. The motorised unit is without any forced ventilation (fans) and completely silent, making the unit ideal for acoustic critical applications (TV studios, concert halls et al.)
