      Comments about Kramer VM-4HD 1x4 SDI & HD-SDI (HDTV) Video Distribution Amplifier:

      If you need to run long stretches of DSI signals (SD or HD) this little box reamplifies the signal for you easily and not just that you can run 4 new signals out from the box.
      Or just use it to get up to 4 new streams from one source.
      In live production this is a must have item.

      Plug it in to power, and plug in your BNC connectors and it works, easy as that!
