Live Events/When hotel A/V fails on stage
When the in-house A/V
starts failing on stage.
I sat in the audience at a downtown DC summit recently. Not running the A/V — a planner had invited me as a guest. Within twenty minutes I couldn't follow what the speaker was saying, because I couldn't stop hearing what the equipment was doing.
It's not bad luck. It's cheap gear on shared frequencies.
It started with a handheld mic. Awful noise, loud enough that someone at the back of the room had to physically kill it. There were four mics on the session — two handhelds, two lavalier body packs — all running on fixed frequencies, all off-brands I didn't recognize. Fixed frequencies are the tell. In a shared hotel with multiple ballrooms running events at the same time, if any other mic in the building is on the same channel and gets switched on, the signal goes to war. Yours dies mid-sentence.
Then a burst of wireless interference cut straight through a speaker's answer to a question. Twice.
Then a speaker at the back of the room started clicking and popping — not once, but on and off, for over an hour. Once you noticed it, you couldn't stop hearing it. I watched people two seats over not even react. Either they hadn't clocked it or they'd given up caring. Either way, my ear had already given up on the content.
The moment that stayed with me: a well-known presenter on stage stopped mid-sentence and made a live comment about the mics. In front of the entire room. That's what venues are pitching when they say "you don't need to bring in your own production company."
- Fixed-frequency wireless — dies when a nearby mic on the same channel switches on
- Off-brand equipment specified for cost, not coordination
- No frequency scan before doors open — so conflicts show up mid-show
- House speakers with intermittent hardware faults nobody's tested
- No redundant mic on standby when a handheld starts failing
The audience doesn't need to know why. They just feel it.
You don't need a technical audience to lose a room to bad audio. Feedback, clicking speakers, mid-sentence dropouts — none of it needs explaining. The audience registers it as "this event isn't quite right" and starts checking their phones.
The presenter you booked has their credibility tarnished by feedback, not by anything they said. Everything they present after the first pop lands 20% softer, because the room has already downgraded its trust in the room itself.
And the 20–30% of your attendees who are technical enough to know exactly what's failing? They remember it. Sharply. Those are your future speakers, your future sponsors, and often your future clients. They walk out remembering the popping speaker, not your program.
The kicker: your organization's name is on the event. The venue's name isn't.
Coordinate the frequencies. Rehearse the recovery.
When we run an event, frequency coordination happens before we ever leave the shop. Every wireless channel gets assigned, scanned, and logged. During load-in, we scan the room for conflicts with other events in the same building — because in a downtown hotel, you're never the only show. Every wireless channel gets a backup on standby, powered off, ready to be swapped in mid-show if something starts drifting.
Every speaker gets walked to and listened to before doors open. If a driver is failing, we find it during setup, not during the keynote. If something's going to fail, we've already rehearsed the recovery — most of our saves are the ones you never notice.
The reason venues can pitch "you don't need to bring in your own production company" with a straight face is that most planners aren't in the audience during the keynote. They're in the green room, checking on the next speaker. They never see what the audience sees. We do — because for years now, the room I'm sitting in is the room I'm responsible for.
- Frequency coordination before load-in, not during the show
- Backup wireless channels powered off and ready to swap in
- Every speaker walked, listened to, and cleared before doors open
- Handheld and lavalier redundancy for every keynote
- Broadcast-grade wireless (Shure Axient, Sennheiser G4/EW-DX) — not fixed-frequency Amazon gear
- A tech in the room during every session, not just at load-in
