The HDX-Ultimate uses only one CAT5e cable to extend 4K HDMI signals hundreds of feet from their source. The Ultimate’s technology is HDTV-ready and PoE, ensuring peak performance even when transmitting ultra-high quality picture resolution. The HDX-Ultimate is a crucial extender for any system, and works in tandem with SmartAVI matrixes for robust routing configurations. Control and extend setups up to 300ft per side and 450ft when both are powered. Plus, with RS-232 and IR remote control, taking command is convenient and easy every time.
