Audio engineers are in charge of all the audio-related things, making sure that it sounds absolutely amazing in the room. They’re tuning the room, making sure that there’s no feedback and that the audio plays at the right volumes.
 
When the CEO comes out, they’re the ones bringing up the audio to make sure that everything sounds great. Sometimes, you’ll have a secondary A1 as well, someone to the side of the stage, for example, if you have a band and you need them to mix all their in-ear systems.
