KPO Radio, San Francisco
Master Control, 1929


Anne Jetters, KPO’s telephone exchange operator, and Orrin Brown, station technician, try out the Hale-Chronicle station’s new audio control room. The equipment was installed at the same time as the new 5,000-watt Western Electric transmitter. It consisted of a master control audio console and five racks of audio amplifying and switching equipment. An early condenser microphone can be seen at the operator’s position next to Miss Jetters.
