Or: “What is feedback? And what can I do about it?” Frequently in movies someone will walk up, tap a microphone and it squeals. That squealing sound is a miniature version of feedback. Feedback is probably the most common event audio problem. It’s typically an extended, high pitched squeal or wail. Feedback is a loop: Sound goes…

Sometimes before an event you ask yourself, “What am I forgetting?” If you’ve got a good AV partner hopefully you’ve covered these already, but here’s a few things to check off:

Or “What size screen do I need?” Have you ever been to an event where you couldn’t read the words on the screen? I recently went to a speech where the screen was so small only the first couple rows out of a few hundred people could be expected to see it. How do you…

The day of the event the first executive loads her slide deck, but…

Or: “How can I lower my AV costs?” I had talked to a client about their event, this was the first time this particular meeting was being held. It was a few days, with a general session and four breakout rooms along with a special awards gala. I put together a proposal and sent it.…
