A communication system is provided which allows closed circuit television pictures to be transmitted from conventional TV cameras to conventional monitors via an ordinary pair of wires, for example, telephone wires, lamp cord, BX cable, etc., over limited distances without measurable degradation of picture quality. A balanced system is provided with dual inputs and outputs so that the system can accommodate simultaneous transmission of audio or other data. Adapters are provided on the receiving end and on the sending end which provide conversion, impedance matching, and the frequency compensation required in order to provide uniform frequency response for the quality transmission of television as well as audio and/or other data.
