Codigo do Produto: #351




 

Característica

› Descrição

The 711N and 712N are a twisted pair transmitter and 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 - Only one unit in a system, the transmitter or the receiver needs to be connected to a power source.
     
  • System Range - Up to 400 meters (1200’).
     
  • Cable - UTP (unshielded twisted pair) such as CAT5.
     
  • Compact Size - Part of the Kramer TOOLS™ family of compact, high quality and cost effective solutions.
