How do you fix a problem mid-show?

The show-caller makes the call and the backup is already patched and powered. That is the entire reason we insist on both — recovery mid-show is a rehearsal outcome, not an improvisation.

How much power should we order for an LED booth wall?

Work from the panel specification rather than a rule of thumb. Indoor panels typically average 150 to 350 watts per square metre with a peak well above that, so a 12 square metre wall plus processing, players and accent lighting commonly needs a 15 to 20 ampere three-phase feed to run comfortably. Order to measured peak plus headroom, because an under-ordered feed is the most expensive saving at an exhibition.

LED wall or large-format screens for a stand?

LED wins for brightness in a daylight-affected hall, for seamless large areas and for non-standard shapes. Screens win for small stands, for close-up detail content and for budget. For anything above roughly 6 square metres of display area, LED is usually both brighter and better value than tiling screens, and it survives being looked at from two feet away less well, which is worth considering for text-heavy content.

Can the stand team run the AV themselves?

Yes, if it is designed for that. Scheduled power-on and shutdown, auto-playing local content, a single remote for source changes and one printed page of instructions will cover almost every situation. What they cannot do is re-map a processor or repatch a failed player, which is why a technician on call in the hall for the show days is normal on anything larger than a single screen.

Why does exhibition build cost more per hour than other events?

Because the window is fixed, shared and short. Thirty-six hours of access, one marshalling yard, queuing lifts and an organiser clearance deadline mean crews work compressed shifts with overtime, and preparation that would be optional elsewhere becomes mandatory here. The kit is often cheaper than a conference rig; the labour, the handling and the organiser-mandated contractor charges are what move the number.

How do we stop our audio annoying the neighbours?

Design for your own stand footprint only. That means near-field or directional speakers aimed down at visitor height, multiple small sources rather than two loud ones, headphone stations for long-form content, and a measured level cap at the stand boundary. Set it during the build with the hall quiet and then re-check once the hall is full, because the noise floor rises and operators creep the level up.

AV Mistakes That Ruin Exhibitions & Trade Shows — and How to Avoid Them

Key takeaway

The recurring AV failures at exhibitions & trade shows are undersized systems, no redundancy, content arriving late, no rehearsal, too many vendors and no single show-caller. Each has a specific, cheap countermeasure if it is decided in advance rather than on the day.

Key takeaways

The booth trips and takes a section of the hall's phase with it
The power order is placed at half the real load to save money
Content arrives in the wrong aspect for a non-standard LED canvas
The truck sits in the marshalling queue and the build window shrinks

What goes wrong, and the fix

What can go wrong

How we prevent it

What can go wrong
The booth trips and takes a section of the hall's phase with it.
How we prevent it
Calculate draw per circuit honestly, order the correct feed from the appointed contractor, balance across phases, and put inrush-heavy LED and lighting on separate protected circuits with their own breakers.
What can go wrong
The power order is placed at half the real load to save money.
How we prevent it
Produce a written load schedule per device at design stage, size the order to measured draw plus headroom, and treat the contractor's feed cost as fixed infrastructure rather than a negotiable line.
What can go wrong
Content arrives in the wrong aspect for a non-standard LED canvas.
How we prevent it
Issue the exact pixel canvas map and safe area to the content team at briefing, and test the real files on the real processing during the build rather than on a laptop.
What can go wrong
The truck sits in the marshalling queue and the build window shrinks.
How we prevent it
Book a load-in slot, load in build order with numbered cases, and send a small advance team to secure the footprint while the vehicle waits its turn.
What can go wrong
Booth audio spills and the organiser orders it switched off.
How we prevent it
Design short-throw, downward-facing coverage over your own stand area, set a measured level at the stand boundary, and use directional or near-field speakers rather than a pair of full-range boxes.
What can go wrong
The system does not come back after an overnight hall power event.
How we prevent it
Set players and processors to auto-power-on and auto-play, schedule start-up before hall opening, and keep a small uninterruptible supply on anything with a long boot sequence.

When to decide each one

8 weeks out
Stand design and power schedule
Screen sizes, canvas shapes and device list fixed, with a written per-circuit load calculation to drive the organiser power order.
6 weeks out
Organiser submissions
Power order, structural and rigging declarations, and contractor passes submitted against the organiser's published deadlines.
4 weeks out
Content specification issued
Pixel canvas maps, safe areas, resolution, codec and loop duration issued to the content and brand teams.
2 weeks out
Content delivery and dry build
Final files received and played on identical processing in the warehouse; LED panel sets pre-assembled and tested.
T−48 to T−2 hrs
Build and handover
Load-in, structure, power, screens, content and a tested handover to the stand team with a printed operating note.
Final day, post close
Strike
Derig to the organiser's clearance deadline, with content drives and hired devices reconciled against the manifest.

The pattern underneath

Almost every failure above is a decision taken too late rather than a technical limit. Then the rig has to run unattended for nine hours a day, three days running, with a client-facing team that has no technical training. That means a looped playback system that recovers automatically after a power event, scheduled start and shutdown, content held locally rather than streamed, screen brightness set for a hall with open roller doors and daylight at the ends, and a written single-page operating note taped inside the store cupboard. Booth audio needs a deliberately short-throw design so it serves your stand without being the reason your neighbour complains to the organiser.
