707, Video-Audio Line Transmitter 



 

 

The 707 and 708 are a twisted pair transmitter and receiver for composite video and unbalanced mono audio signals. The 707 transmitter converts a composite video and audio signal to a twisted pair signal and the 708 receiver converts the twisted pair signal back into composite video and audio signals.

Typical Applications:

  • Remote monitoring for CCTV, medical, schools, broadcast applications.

  • Ideal for existing facilities with TP cable already installed

  • Teleconferencing in offices and hospitals using existing intercom or telephone wiring

 

FEATURES

 
  • Bandwidth - 58MHz (- 3dB) at 400 Meters.

  • Twisted Pair Connectors - RJ-11 (phone).

  • Level (Gain) and EQ (Peaking) Controls (708).

  • Looping Input (708).

  • Selectable Input Signal Termination (708).

  • Audio Input Level (707) - Line or condenser mic (selectable).

  • INV Polarity Switch (708) - Inverts the incoming polarity.

  • System Range - Up to 1000 meters (3200’).

  • Cable - UTP (unshielded twisted pair) such as CAT5.

  • Compact Size - Part of the Kramer TOOLS™ family of compact, high quality and cost effective solutions.
