Composite Video & Stereo Audio over Twisted Pair Transmitter


FREE Shipping on orders over $100

The 711N is a twisted pair transmitter 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.

Features & Benefits

  • 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.
