Extron has started shipping the MTP 1500RL 15HD RS and MTP 1500RL 15HD RS SEQ Extended Distance Twisted Pair Receivers for VGA and RS-232. These receivers work with MTP Series transmitters to send high resolution video 1,500 feet or more and RS-232 signals up to 1,000 feet over a single CAT 5-type cable. The extended distance receivers are compatible with resolutions up to 1920×1200 WUXGA, and feature separate continuously variable level and peaking adjustments that precisely optimize image quality for various cable lengths. Each receiver also offers an additional female MTP buffered output, enabling up to eight receivers to be connected in series, reducing the number of parallel cable runs required. The SEQ model adds independent skew compensation adjustments for each color.
The extended distance receivers are housed in low profile, rack-mountable metal enclosures that can be discreetly mounted in racks or behind wall-mounted displays. They are compatible with the MTP Series of transmitters, switchers, distribution amplifiers, and matrix switchers and you can see all the specs at: http://www.extron.com/product/product.aspx?id=mtp1500rl15hdrsserie&search=MTP%201500RL
Just consider the weight of cable and amplifiers needed to run analog over these distances, and you’ll see the niche this product can fill for stagers.
