Operations technicians are the daily users of the equipment and are usually either program or production oriented. The division of job responsibilities among types of Broadcast Technicians is not always clear. Broadcast Technicians work with microphones, sound recorders, light and sound effects devices, television cameras, video tape recorders, and motion picture projection equipment. Broadcast Technicians in small stations perform a wider variety of duties than those in large stations and networks, where assignments may be specialized. Video Tape Recording Operators operate and maintain video tape equipment to transcribe live programs.
Many stations use computers to edit material electronically.
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.
