The Lang Center, located on the 2nd floor of 55 W 13th Street has undergone an upgrade to the audio visual system. In Spring 2013, the analog standard definition video and audio components have been replaced with a digital HD video and audio system, with advanced streaming and recording capabilities. The projectors have been replaced with new single-chip DLP, high brightness/contrast HD video projectors. The East screen has moved to the Southeast window to provide maximum viewing for presentation. An HD camera with remote pan/tilt/zoom control has been added for pick-up of Center Hall presenters and stage for broadcast quality HD video. To help traffic “Event in Progress” signs have been located outside of the Lang Center.
