What goes wrong, and the fix
What can go wrong
How we prevent it
- What can go wrong
The chief executive rewrites their deck twenty minutes before walking on.
How we prevent itRun a watched hot-folder with a second operator whose only job is late versions: ingest, check fonts and embedded media, and play the new file once on the backup machine before it goes anywhere near the screen.
- What can go wrong
A visiting speaker insists on presenting from their own laptop.
How we prevent itAllow it, but only through a pre-tested scaler with the right adaptor and a confirmed output resolution, and keep a copy of their file parked on the house machine as the fallback path.
- What can go wrong
Breakout rooms interfere with each other on radio microphones.
How we prevent itScan the venue RF environment at the recce, allocate fixed frequency blocks per room in writing, and use coordinated digital systems rather than whatever happens to be clear on the morning.
- What can go wrong
Q&A collapses because two roving mics ring or nobody can find the questioner.
How we prevent itBrief two runners with assigned aisles, gate the roving channels at the desk, and have the show-caller put the camera and a light on the questioner before the microphone is opened.
- What can go wrong
The remote audience hears a muddy open room mic and drifts away.
How we prevent itBuild the stream mix from console direct outs with its own engineer, and monitor it on the actual platform rather than trusting the meters on the desk.
- What can go wrong
Hotel air handling or an adjacent banquet bleeds into the hall.
How we prevent itRaise it at the recce, get engineering settings and neighbouring banquet timings agreed in writing, and design coverage with distributed fills so you are not fighting noise with volume.
When to decide each one
- 8 weeks out
Run of show lock
Session order, speaker list, durations and the house slide template agreed so the AV design has something fixed to solve.
- 6 weeks out
Recce and technical design
Rigging points, ceiling height, power, sightlines and dock access surveyed; screen and audio design issued as drawings.
- 3 weeks out
Content pipeline opens
Template circulated to every speaker with a hard submission date plus aspect-ratio, font and video-codec guidance.
- 1 week out
Deck freeze and dry run
Everything received is ingested and run end to end; missing decks escalated to the organising committee by speaker name.
- T−1 day
Technical rehearsal
Build complete, speakers walked through, cue sheet printed and distributed to every crew position.
- T+2 days
Handover
Session recordings, stream analytics and final content files delivered in the agreed format.
The pattern underneath
Almost every failure above is a decision taken too late rather than a technical limit. Audio comes third in most briefs and first in every post-event complaint. Hotel ballrooms are wide, low and carpeted, with pillars and audible air handling, so coverage needs distributed fills rather than one loud pair at the proscenium. Delegate microphones for a dealer meet, roving mics for Q&A with a disciplined operator, and a stream mix that is not simply the room mix are three separate line items, not one. If sessions are being recorded for internal reuse, the recording mix deserves its own engineer and its own monitoring position.
