KRAMER TR-1 Video Isolation Transformer

 
   
      The TR-1 is a high-resolution video isolation transformer for composite video signals. It provides complete isolation between devices to eliminate video hum, ground loops, and DC offsets, which can degrade picture quality.
          o Bandwidth - 5.8MHz (-3dB).
          o Passive (no power required).
          o Compact Kramer TOOLS™ - 3 units can be rack mounted side-by-side in a 1U rack space with the optional RK-3TR rack adapter.
