ATT-475 allows a ceiling mounted projector to be used for 2 screens. The motorized ATT-475 is designed to turn 90 degree such that 2 screens mounted on different sides of the room can be projected selectively. This will save space and eliminate the need for a second projector, hence reducing cost. ATT-475 is one of the first of its kind in AV industry. It comes complete with a RF remote control and can also be controlled by other room control system.
