The unit a twisted-pair signal from the receiver, then converts it to composite video and stereo audio signals for output. This solution is well suited for use in educational institutions, broadcast studios, and medical facilities, among many other potential uses.

Other features include a looping input, selectable input signal termination, level (gain) & EQ (peaking) controls, and bandwidth of 85MHz. It offers a general working range of up to 1200', although greater distances may be achieved dependent up on signal resolution and cable type. This device is designed to work with unshielded twisted-pair cable such as CAT5.

This product features Kramer's Power Connect technology, meaning that only one device in the system needs to be connected to an electrical source to power all system units (all units in the system must feature Power Connect technology to use this feature).

Note: This unit must be paired with a 711N transmitter unit in order to achieve a complete solution.
