Video operators control panels of video consoles. They set switches and observe readings to control the contrast, brightness, color, quality, and size of television pictures. Audio operators regulate volume level and quality of sound by adjusting controls and by mixing various audio elements. They assist in determining the number, type, and approximate location of microphones needed for best sound quality. Microphone-Boom operators position microphones to pick up voices of performers in a way that does not distort the voice or interfere with studio lighting.
Projectionists operate film and slide projection equipment.
Transmitter operators operate and maintain television transmitters according to regulations of the Federal Communications Commission. They monitor incoming and outgoing signals to assure strength, clarity, and reliability. Stations are comfortably cool because transmitters and other electronic equipment must be operated at controlled cool temperatures. When necessary they work outside, sometimes in remote areas. Depending upon the job, physical activity varies from sedentary to strenuous.
