Sound

This is where the audio engineer (sound supervisor in the UK) uses a mixing console (being fed with all the various audio feeds: reporters, commentary, on-field microphones, etc.) to control which channels are added to the output and follows instructions from the director. They ensure that the audio is within pre-set limits, typically with the help of peak programme meters and loudness monitors. They relay the information from producers and directors to their A2‘s (audio assistants) who typically set up the audio cables and equipment throughout the arenas and the booth where the commentators sit. The audio engineer normally also has a dirty feed monitor to help with the synchronization of sound and video. Intercom is also generally the responsibility of the sound department.

CrewAudio mix engineer (A1) (also known as audio mixer, audio director or sound supervisor) – The A1 mixes the sounds that the audience will listen to. They will mix the assorted sounds such as crowd noise, effect sounds, announcers, etc. They route the different sources of sounds from microphones, cameras, discs, video tapes, telephones, EVS, or outside audio sources, into the audio mixing board for control. They are also in charge of ensuring the audio is successfully being transmitted. They also ensure the intercom is working for every station in the production, as well as dial-up coordination with a network director.^[16]

Audio assistant (A2) – The A2s work under the direction of the A1 as they set up all the audio equipment around the venue for various sounds. They also set up the intercom system between the production truck and stage or announcer booths. They are also in charge of placing microphones on the talent as they enter and exit.^[19]
