  • With its large bandwidth it can handle even very high resolutions and refresh rates, up to 1600 x 1280 pixels at up to 85 Hz
  • Includes two serial keypads, so it's ready to go right out of the box
  • Because it has a universal power supply, you can plug it in almost anywhere if you have the right input cord
  • Small and light enough to take almost anywhere
  • Designed to carry VGA/XGA video, but it can handle separate horizontal and vertical sync, composite sync, and sync on green (with proper cables and adapters)
  • All input and output signals are buffered for the sharpest possible images
  • Can drive video signals to over 300 ft(100 m) end-to-end, so it is ideal for use in auditoriums, conference halls, and similar spaces
  • The front-panel LEDs show you right away which video inputs are going to which outputs
  • RS-232 ports allow control from included keypads or other serial device (using simple ASCII strings)
  • Designed and manufactured in the USA
  • CE and FCC tested and certified
