This briefcase converts into a lectern and battery powered public address system in seconds, providing a convenient platform for organizing presentation materials and amplifying lectures. The built-in sound system has a 20-watt amplifier and dual, 4" speakers that produce crisp sound from the briefcase's front panel, ensuring crystal clear orations. The 14" by 15" lectern props up the briefcase and easily accommodates legal pads and note cards. The unit provides two microphone options--a handheld condenser microphone with nine feet of cable and a 3/4" lavaliere model that clips to a tie or lapel. The control panel on the side of the briefcase enables tone and volume adjustments and the 13" gooseneck arm attaches to the briefcase and secures the handheld microphone at your preferred height. All components store inside the briefcase with room to spare for documents, the attaché combination lock provides optimal security, and line-out ports enable connection to external speakers and a tape recorder. Can be powered for up to four hours by eight C batteries (not included) or plugs into AC. 13" H x 18" W x 5" D. (15 lbs.)
