This 35179I Advantage Deluxe Electrol 16:9 HDTV Format Motorized Projection Screen from Da-Lite has a 90.0 x 160.0" viewing area with a Matte White HC (High Contrast) flame retardant and mildew-resistant finish. With its 1.1 Gain rating and 50° (L/R) viewing angle, this special gray finish is optimized for use with LCD, DLP and D-ILA projectors. Matte White HC is good choice when ambient room light can be controlled and video is the dominant projected source. The gray base and reflectivity of the finish produce good blacks without sacrificing the white levels. If the finish becomes soiled, it can be cleaned with mild soap and water.
One of the major advantages of this screen is that the fabric roller can either be factory installed or at your chosen location after the ceiling recessed, UL Plenum rated extruded aluminum white housing has been roughed in. The enables you to finish the initial installation but choose your screen finish at a later date.
The screen includes two motors; one for the ceiling door and one for the fabric. The interior roller features a quick reversal motor, oiled for life, with automatic thermal overload cutout, integral gears, capacitor, and an electric brake to prevent coasting when the screen is stopped at a chosen length. The built-in Low Voltage Control controls up/down and stop functions using the included 12VDC three-position switch that can be wall mounted where convenient. It can also be operated from an optional radio frequency, infrared or auxiliary transmitter.
The Video Projector Interface provides a way for the screen to be automatically raised or lowered via either a 12 or 5V lead from the projector. The connection must be provided with the projector for the interface to work.
