The AV Disaster Checklist: How to Prevent Event Tech Failures

Technical failures can derail any event — but most are totally preventable. Use this checklist to identify common risks before your event even begins.

No event planner wants to hear the words: “The microphone isn’t working.” Presentation failures, audio feedback, internet outages — these problems can quickly disrupt an otherwise successful event, and attendees rarely remember why they happened. They simply remember that they did.

While no live production is completely risk-free, most event tech failures are preventable with proper planning and experienced technicians. The best AV teams spend as much time preparing for potential problems as they do planning for success.

Use this checklist to get ahead of the most common risks before your next event:

AUDIO

Verify Proper Speaker Coverage

Poor speaker placement leaves sections of your audience straining to hear. The goal isn’t maximum volume; it’s clear, intelligible sound for every person in the room.

Before the Event

✦  Confirm speaker locations relative to the audience layout

✦  Walk the entire audience area during sound check and listen for dead spots

Test Every Microphone

One bad microphone can ruin an entire presentation. Never assume equipment is working simply because it worked the last time it was used. Every microphone in the system needs to be checked before doors open.

Before the Event

✦  Test every microphone individually

✦  Check and replace batteries as needed

✦  Confirm microphones are labeled correctly

Coordinate Wireless Frequencies

Wireless microphone dropouts are among the most common audio failures during an event. In hotels, convention centers, and large corporate venues, multiple wireless systems can end up competing for the same frequencies if not coordinated correctly.

Before the Event

✦  Scan the RF environment

✦  Identify other wireless systems operating in the venue

✦  Coordinate all wireless frequencies to avoid interference

✦  Place antennas strategically for maximum signal coverage throughout the room

VIDEO & GRAPHICS

Test Every Presentation

Most presentation failures happen because content was never tested on the actual playback system. A file that looks perfect on a presenter’s laptop may render entirely differently on the event computer — especially if fonts, animations, or embedded videos are involved.

“Never assume a presentation will behave the same way on a different computer. Test everything on the actual playback system before the audience arrives.”

Before the Event

✦  Open every PowerPoint or Keynote file on the event computer

✦  Verify videos play correctly and with audio if intended to

✦  Check fonts, formatting, and slide animations

✦  Confirm all content is accessible without internet access if necessary

Prepare Backup Playback Options

Technology can fail at the worst possible moment. Professional AV teams always have a backup playback machine ready so that when a primary device goes down, the show continues with no disruption.

Before the Event

✦  Stage a backup presentation computer with all files loaded

✦  Store duplicate media files on a separate drive

✦  Confirm cloud-based file access as a last resort option if possible

Verify Display Visibility

A perfectly functioning screen is useless if attendees can’t comfortably see it. Also, make sure presenters can clearly see their downstage monitors. Screen size, brightness, and sightlines all determine whether your content is actually readable from everywhere in the room.

Before the Event

✦  Walk the room and check sightlines from all seating sections

✦  Test content readability and font sizes at normal viewing distance

✦  Confirm projector or display brightness levels for showtime lighting conditions

POWER & INFRASTRUCTURE

Confirm Power Requirements

Power issues can create widespread, cascading failures. Overloaded circuits can take down critical systems mid-show — and in many venues, finding additional power during an event is simply not an option.

Before Setup

✦  Verify venue power availability and dedicated circuit access

✦  Confirm total equipment power requirements before load-in

✦  Plan cable routing to avoid hazards in audience and presenter areas

Secure Cables and Connections

Loose or unsecured connections cause more preventable failures than most people realize. A single disconnected cable can stop a presentation instantly — and in a high-traffic event environment, it’s a constant risk.

Before Doors Open

✦  Secure and tape all cables in high-traffic pathways

✦  Verify all signal connections are seated properly

✦  Confirm adapters and converters are working correctly

INTERNET & STREAMING

Test Internet Speeds

For hybrid events and livestreams, internet reliability is non-negotiable. Public venue Wi-Fi is rarely suitable for broadcasts. Test everything early — and have a contingency ready.

Before the Event

✦  Run speed tests and verify upload bandwidth at the venue

✦  Test streaming platforms end-to-end before the show

✦  Confirm a dedicated wired connection for all critical broadcast equipment

Have a Backup Connectivity Plan

Internet outages happen. A minor connectivity issue can become a major public failure if there’s no fallback in place. Build redundancy into your setup before the event starts — not during it.

Before the Event

✦  Prepare cellular hotspot backups for critical connections

✦  Set up a secondary network connection where possible

✦  Configure local recording as a failsafe for streamed content

REHEARSALS

Conduct a Full Technical Rehearsal

Many event problems only reveal themselves once presenters, videos, microphones, and show cues are all running together. Rehearsals exist to surface those problems — not to confirm everything is already fine. Even a short walkthrough can dramatically reduce showtime surprises.

During Rehearsal

✦  Run audio cues in the system

✦  Test all video playback content at show levels

✦  Identify any microphone assignment errors or timing mismatches

Verify Show Flow

Every transition is a potential failure point if it hasn’t been tested. Walk through the full show sequence to confirm each handoff — from presenter introductions to audio/video cues to audience Q&A — runs cleanly from start to finish.

During Rehearsal

✦  Walk through presenter introductions and any handheld microphone handoffs

✦  Confirm video cues fire at the right moment

✦  Test audience Q&A setup and confirm closing remarks logistics

Pre-Show Checklist: Last Checks Before Doors Open

✦  Confirm all wireless frequencies are coordinated with no interference

✦  Walk the room and verify coverage to audience

✦  Brief every presenter on microphone technique before they take the stage

✦  Verify all presentation files are loaded and tested on event computers

✦  Confirm backup microphones are charged, labeled, and within immediate reach

✦  Establish secondary signal paths and verify internet redundancy is in place

BACKUP EQUIPMENT

Prepare Critical Spare Equipment

Experienced AV teams rarely arrive with only one solution for anything. Stocking the right backup equipment is one of the simplest and most high-value things any AV team can do.

Always Have On-Site

✦  Backup wireless microphones, ready at a moments notice

✦  Extra batteries, cables, and adapters for all critical systems

✦  Backup playback devices and power supplies

Build Redundancy Into Critical Systems

The most important systems at your event should never rely on a single point of failure. When redundancy is built in correctly, the audience never notices when a backup system is activated — because everything continues without interruption.

“The most successful events aren’t the ones that experience zero problems — they’re the ones that are prepared when problems occur.”

Build Redundancy Into

✦  Microphone systems — always have a ready backup within reach

✦  Playback computers — a duplicate device with all files loaded

✦  Signal paths — secondary routing established before the show begins

STAFFING & COMMUNICATION

Ensure Experienced Technicians Are On-Site

Equipment alone doesn’t prevent failures — people do. Experienced technicians monitor systems continuously, catch problems before the audience notices, and respond quickly when something goes wrong. Preparation matters, but real-time expertise matters just as much.

During the Event

✦  Keep technicians actively monitoring all systems throughout the show

✦  Assign clear responsibilities so every system is overseen by someone on the crew

Establish Clear Communication Channels

When something goes wrong during an event, speed matters. Clear communication between crew members, event coordinators, and decision-makers is what allows a team to resolve issues quickly — before the audience even realizes there was a problem.

Before the Event

✦  Identify key decision-makers and their contact info

✦  Establish communication channels for all crew members

✦  Review emergency procedures and paths before doors open
