The PRO4500DP is a Digital Multimedia Projector that is ideal for big-impact presentations in large venues, even when the space is fully lit. It features an amazing 5000 ANSI of pure brightness, an XGA output and a 2000:1 Contrast Ratio. With Texas Instrument?s DLP Technology and the projector's power zoom and focus, it?s easy to manage and a cost-effective alternative to single 10,000-lumen units. Users can also choose either single or dual lamp mode, and the projector will cycle from one lamp to the other to ensure balanced use for extended lamp life. Furthermore, it also has a sophisticated network capability to accommodate the most complex presentations and satisfy the most demanding users. It integrates seamlessly with computers, printers and other peripherals, and all systems may be monitored and operated remotely from a central location. It handles massive data beautifully and delivers discreet audio output for each video input.
