712N

The 712N is a twisted pair receiver for composite video and unbalanced stereo audio signals. The 711N transmitter converts composite video and stereo audio to a twisted pair signal and the 712N receiver converts the twisted pair signal back into composite video and stereo audio signals.
  • Bandwidth - 85MHz (−3dB).
  • Twisted Pair Input/Outputs - RJ−45 connectors.
  • Looping Input - 712N (RJ−45).
  • Selectable Input Signal Termination - 712N.
  • Level (Gain) and EQ (Peaking) Controls - 712N.
  • Power Connect™ System - A single connection to the transmitter or the receiver powers both units when the devices are within 150ft (50m) of each other.
  • System Range - Up to 400m (1200ft).
  • Cable - UTP (unshielded twisted pair) or STP (shielded twisted pair) such as CAT 5.
  • Compact Kramer TOOLS™ - 3 units can be rack mounted side−by−side in a 1U rack space with the optional RK−3T rack adapter.
