4 x 4 Matrix for HDMI w/ 4 ERL-POL Outputs, 225MHz, 330ft Max, 1080p, 1920 x 1200, RS-232, 2U
Route any four HDMI sources and Bi-Directional IR control to four different locations up to 330 feet (100 meters) away, using HDBaseT over a single CAT-5e cable
The GefenPRO 4x4 Matrix for HDMI w/4 ELR-POL Outputs and Bi-Directional IR routes up to four Hi-Def sources at resolutions up to 1080p Full HD with Deep Color and multi-channel digital audio to any of four HDTV displays, using FST to speed up the HDCP authentication process. Each of the included ELR-POL Receivers units are used to extend HDMI to four locations, using Gefen ELR (Extra Long Range) and POL (Power Over Line) technologies. ELR is based on HDBaseT and allows the extension of HDMI using a single CAT-5e cable. POL eliminates the need to externally power the Receiver units. The GefenPRO 4x4 Matrix for HDMI supports 3DTV pass-through and eight channel digital audio formats such as Dolby TrueHD and DTS-HD Master Audio. 3D content can be displayed when connecting a 3DTV and 3D source. Each source is accessible at all times from any display location. Bi-Directional IR allows each connected source to be controlled from any of the viewing locations, as well as each Hi-Def display being controlled from the source location. The IR All Out port on the matrix broadcasts IR commands from any of the viewing locations to all sources. The IR All In port on the matrix broadcasts IR commands from an automation control device by the matrix to all remote displays. The matrix can be controlled by via the included IR Remote, RS-232, IP control (Telnet or web server interface), or by using the front-panel push buttons.
<b>How It Works</b>
Using HDMI cables, connect up to four Hi-Def sources to the four HDMI inputs on the matrix. Connect up to four HDTV displays to the included Receiver units, also using HDMI cables. Use a single CAT-5e cable, up to 330 feet (100 meters), to connect each of the Receiver units to the matrix. To control each Hi-Def source from the display location, connect an IR Extender (Gefen part no. EXT-RMT-EXTIRC or EXT-RMT-EXTIRN) to the IR Ext jack on each Receiver unit. Connect an IR Emitter (Gefen part no. EXT-IREMIT) to the corresponding IR Out for each source input on the matrix and place the IR emitter over the IR sensor of the Hi-Def source. Point the IR remote of that source towards the IR Extender at the display location to control the source. To control the display placed near the Receiver unit, connect the IR Emitter output from an automation device (such as the Gefen PACS or MINI-PACS) to the corresponding IR Input on the matrix. Connect an IR emitter (Gefen part no. EXT-IREMIT) to the IR Out on each Receiver unit, and attach the IR emitter over the IR sensor of the display. Connect the included AC power cord to the matrix and connect it to an available electrical outlet. Power to each of the Receiver units is delivered from the matrix.
<b>Gefen FST</b>
Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST allows for connecting/disconnecting or turning any of the HDTV displays on or off without affecting other displays within the audio/video distribution system.
