The TT560 is designed for operation over Category rated cable or twisted pair communication cable and requires a Nitek active receiver unit. The unit works equally well over existing communication and computer networks or newly installed cable. A highly balanced transmitter output design assures that the system will not interfere with other equipment on the network. In addition, the transmitter is virtually impervious to ground loop and has high immunity to noise and interference. Built-in surge suppression is standard.

A dip switch on the unit provides precise adjustment of gain and frequency compensation, allowing the system to be "fine-tuned" to the cable.
