Broadcast and sound engineering technicians typically do the following:

• Operate, monitor, and adjust audio, video, lighting, and broadcast equipment to ensure consistent quality
• Set up and take down equipment for events and live performances
• Record speech, music, and other sounds on recording equipment or computers, sometimes using complex software
• Synchronize sounds and dialogue with action taking place on television or in movie productions
• Convert video and audio records to digital formats for editing on computers
• Install audio, video, and lighting equipment in hotels, offices, and schools
• Report any problems that arise with complex equipment and make routine repairs
• Keep records of recordings and equipment used

These workers may be called broadcast or sound engineering technicians, operators, or engineers. At smaller radio and television stations, broadcast and sound technicians may do many jobs. At larger stations, they are likely to do more specialized work, although their job assignments may vary from day to day. They set up and operate audio and video equipment, and the kind of equipment they use may depend on the particular type of technician or industry.

Broadcast and sound engineering technicians share many of the same responsibilities, but their duties may vary with their specific area of focus.

Audio and video equipment technicians set up and operate audio and video equipment. They also connect wires and cables and set up and operate sound and mixing boards and related electronic equipment.

Audio and video equipment technicians work with microphones, speakers, video screens, projectors, video monitors, and recording equipment. The equipment they operate is used for meetings, concerts, sports events, conventions, and news conferences. In addition, they may operate equipment at conferences and at presentations for businesses and universities.

Audio and video equipment technicians may also set up and operate custom lighting systems. They frequently work directly with clients and must provide solutions to problems in a simple, clear manner.

Broadcast technicians set up, operate, and maintain equipment that regulates the signal strength, clarity, and ranges of sounds and colors for radio or television broadcasts. They operate transmitters to broadcast radio or television programs and use computer programs to edit audio and video recordings.

Sound engineering technicians operate computers and equipment that record, synchronize, mix, or reproduce music, voices, or sound effects in recording studios, sporting arenas, theater productions, or movie and video productions. They record audio performances or events and may combine tracks that were recorded separately to create a multilayered final product. Sound engineering technicians operate transmitters to broadcast radio or television programs and use computers to program the equipment and edit audio recordings.

The following are examples of types of broadcast and sound engineering technicians:

Recording engineers operate and maintain video- and sound-recording equipment. These engineers work with computers, computer networks, and software to produce special effects for radio, television, or movies.

Sound mixers, or rerecording mixers, produce soundtracks for movies or television programs. They rerecord songs or compositions that already have been commercially released. After filming or recording is complete, these workers often dub the final product by adding or removing sounds.

Field technicians set up and operate portable equipment outside the studio - for example, for television news coverage. Because this coverage requires so much electronic equipment and the technology is changing so rapidly, many technicians are assigned exclusively to news coverage teams.

Chief engineers, transmission engineers, and broadcast field supervisors oversee other technicians and maintain broadcasting equipment.
