The PT-EW540U WXGA 3LCD Multimedia Projector from Panasonic is a 5000 lumens bright installation class projector that features a native resolution of WXGA (1280 x 800) and a 16:10 native aspect ratio. Featuring an interchangeable lens design, the projector includes the standard lens, a motorized zoom lens which features a 1.7 to 2.8:1 throw ratio. Additionally, it is compatible with a range of separately available lenses from Panasonic, including short throw, zoom, and long throw options.
Designed to be connected to a variety of video sources, for A/V setups of all kinds, the projector supports computers, DVD and Blu-ray players, video switchers, and even legacy analog equipment. It features a VGA input on standard 15-pin connector, a 5-BNC multi-analog input that supports VGA (RGBHV), Component, Y/C (adaptable to S-Video), and composite, a DVI-D (digital only) input, a DisplayPort input, and an HDMI input. It supports HDCP so you can use the projector to watch copy-protected content such as commercial Blu-ray discs, and both the HDMI and DisplayPort inputs support embedded audio as well. For analog audio sources there are three stereo analog audio inputs, two on 3.5mm mini jacks and one on a two-RCA left and right channel stereo pair. Audio can be output through the 10W built-in monaural speaker or sent to a downstream audio device, such as a PA system, via a 3.5mm stereo mini jack audio output. An audio only mode allows audio output even when the picture is switched off. Finally, there is a VGA output that mirrors the VGA input so that a second device, such as a computer monitor, can receive the same signal.
The projector can be controlled locally via side-panel buttons or using the included IR remote. There is an IR extender port in case the installation makes direct line-of-sight communication impossible. Remote control with software or third-party systems is also possible thanks to an Ethernet port at two RS-232 serial ports. The RS-232 port can be used for computer control or integration with automation system such as Crestron. Meanwhile the Ethernet port with Panasonic PJLink protocol support allows IP-based operation from Panasonic software or a Web browser. Alternatively, the Ethernet port can be configured for Panasonic Digital Link, so that HD video and control signals can be sent over a single Ethernet cable when using the projector attached to compatible devices that support HDBaseT.
