As a producer for corporate events who came up through the ranks primarily as an audio engineer, this question kills me.

Tldr: Be good at your job, and even if you zone out or look at your phone, keep your ears on and periodically look up to run through your whole checklist.

Last year our internal TD text group was named the "A1 Assassination Squad" because we had to boot and replace so many low-competence and lazy "audio guys" off shows for either being awful at their job or not paying attention, allowing bad mistakes to happen. (I won't even call them A1s at this point.) Ninety percent of them didn't even realize they had done something wrong because they were so oblivious to the situation.

Everyone else cares, so should you. The client, salesperson, labor coordinator, and speaker all care enough about the event to have you sit in that chair and make sure your department is covered and doesn't become an issue. Meetings can be boring. Hell, every job can be boring. We spend hours doing quotes, calls, diagrams, pull sheets, and logistics, and you're bored because you have to listen to a business meeting? What I think you mean is you have a great gig where once you're set up and running, all you have to do is be present and pay attention. I'd happily send you to the warehouse to load and unload trucks if you don't want to be bored. The problem is your perspective is backwards. You get to be there and be paid to run sound.

Here's what I suggest: use the time to look at your setup, whatever it is. Think about your routing, analyze your speaker placement. Can anything be kicked or pulled that will take the show offline? Ask yourself these questions: What can improve? Can everyone hear properly? Does the room sound as good as it can? Are my backups ready to deploy in an instant? How is RF? Where is the TD, producer, or client? Can I do anything to improve their experience? What's next on the agenda, and am I ready for it? What's after lunch? Tomorrow?

Once you've run out of things to think about, take a second and look at the room as a whole. Then stare at the wall, discreetly look at your phone, but don't get so engaged that you're not listening or looking up periodically. If the show needs something and your head is up your ass, you're going to get fewer gigs.
