We use the same quality material and also features the IR remote and 12 volt trigger of the standard Sapphire Mayfair Tab Tensioned screens. The unusually quiet operation is due to the unique way that the motor section of the housing is separated from the ceiling section of the housing by a rubber seal. This stops any vibration travelling through into the ceiling void, amplifying the sound. An issue found with other In-ceiling designs. This along with the trap door mechanism makes this screen the perfect discreet option for projection. The material on a Tab Tension screen is not only pulled down by the weight of the bar but also from the left and right side by a Nylon string. The string is periodically connected to the material via small Tabs, hence the name Tab Tension. Unlike a standard screen, a Tab Tension screen has a flexible material so that it can be pulled taught from all sides. The Sapphire Tab Tensioned screens have a unique ratchet mechanism at each end of the weighted bar so that the tensioning strings can be easily adjusted should the temperature have any affect on the screen material. The soft touch material is optimised for home cinema use, producing a high contrast and uniform reflectivity. A black PVC backing prevents light leakage so that the screen can be positioned in front of a window. All Sapphire Tab Tensioned electric screens feature built in infra-red remote with external IR control and come with a simple hand held remote. The IR receiver is located on the inside left of the case. Also included is a 12 volt trigger input, this allows the screen to be activated from any projector or surround sound amp with a 12 volt output. A 10m mono mini jack cable is included to connect the screen to a 12 volt output device. If this was not enough you can also control the screen using RS232 or Zero Voltage contact closure.
