A2 (remote television production)
In outside broadcasting using a remote television crew, an A2 (or Audio Assistant) is a person responsible for placement and interconnection of audio devices, such as microphones and intercom, from the Television Production truck to the venue. Typically, in larger productions, there are two or more A2s, responsible to the A1 (or Audio Mixer).
Booth-A2
The Booth-A2 is responsible for setting up and connecting audio equipment for the on-air-talent in the announcers’ booth. This equipment includes on-air announcer’s consoles, handheld-microphones and intercom stations. The Booth-A2 will assist the on-air-talent with equipment.
Field-A2
The Field-A2 sets up the effects-microphones, on-air-talent microphones and intercom on the field. In sports television, these microphones are set up to capture the sounds of the game. These microphones are placed on hand-held television cameras, near goals and pointed by microphone-operators. In some sports, such as golf, there are so many microphones spread over a large venue; an audio-sub mix is required. The Field-A2 will be responsible for sub mixing microphones back to the production truck.
RF-A2
The RF-A2, sometimes referred to as the Wireless-A2, sets up wireless microphones and wireless intercom. The RF-A2 works with both the Field-A2 and the Booth-A2.
Coms-A2
Usually in only the largest productions, there is a Coms-A2 short for Communications-A2. This A2 is responsible for intercom and telephone communications. The Coms-A2 will work with all other A2s to get communications set up.
