  • Abstract
    This paper is limited to a consideration of the audio-frequency elements of a broadcast control system. A two-studio electrically interlocked plant suitable for network operation is described. The methods of specifying and measuring telephonic energy levels, arranging low impedance (as 500-ohm) and bridging apparatus, equalizing lines, and maintaining the audio energy within permissible limits by means of amplifying and attenuating units are described in connection with the specifications of the plant. The co-ordinative and regulative functions of the technical staff of a broadcasting system, the relations of engineering and studio personnel and typical precautions against breaks in program continuity are then discussed.
