With the ProScene EH7500, Optoma present their most bright projector model to the public. Empowered by two 330-watt lamps, the WUXGA projector offers a brightness of 6,500 ANSI lumens. No question the maximum operating time is estimated at only 2,000 hours. The EH7500A wastes a total of 860 watts.
As an installation projector for large indoor spaces such as auditoriums, houses of worship and large meeting rooms, the unit features a fully motorized lens shift, focus and zoom. Of course, Crestron RoomView is a must, the network control and management functions of which are realised via the LAN interface. In terms of picture inputs, there are two HDMI ports, VGA, and various analogue connections.

To stage the DLP DarkChip3 best from any distance, five interchangeable lens options are offered. For 24/7 operation, the projector includes a relay mode with double lamp life and removable multi-purpose colour wheels. The standard colour wheel maximizes the brightness at constant good colour reproduction, while the other colour wheel is optimized for maximum colour precision.
Featuring sleep timer, fast switching on and off and virtually maintenance-free design, the Optoma EH7500 is an environmentally friendly and easy-to-use projector.
