AV Equipment for Events: How to Specify, Price and Verify Sound, Lighting and Screens

Over half of on-site problems are AV: dead lights, feedback, black screens, slides that won't play. Most can be caught before load-in. Here's our checklist.

AV Equipment for Events: How to Specify, Price and Verify Sound, Lighting and Screens

01First, understand: AV has two pricing logics

Two quotes for the same sound system are double apart — before deciding who is expensive, check what pricing logic each one uses.

ModelHow it's pricedTypical for
Fixed package by scale tierTier set by headcount, one fixed package per tier, one price for the whole setSound, lighting
Unit price × quantityPriced on actual square metres, units or people usedLED screens, photo and video
Why the distinction matters

For a tiered quote, ask "how many speakers and lights are in this tier?" For a usage-based quote, ask "beyond the screen itself, are processors and technicians included?" Ask the wrong question and the answer is useless.

02Sound and lighting: six scale tiers

The industry standard splits by headcount and venue type:

TierHeadcountTypical configuration
Ultra-smallUp to 50Portable PA, no professional console needed
Small100–200 indoorBasic full-range speakers + mixing console + wireless mics
Small-medium200–300 indoorFull PA: full-range, subwoofers, monitors, amps, processors, effects
Medium300–500 indoorMore channels, delay fills, multiple wireless mics
Medium-large500–700Line array or array system, professional console, multi-zone fills
Large1,000+ / government conferenceLarge array system, backup console, multi-channel routing

What a 200–300 person sound package should include

Taking the small-medium tier as an example, a complete sound specification usually includes:

  • Full-range speakers — main PA, usually one set per side
  • Subwoofers — low-frequency reinforcement, essential for music-led events
  • Monitor speakers — for speakers and performers on stage
  • Amplifiers — to drive the speakers, matched by power
  • Professional mixing console — 24 or 32 channels, chosen by input count
  • Audio processor — EQ, limiting, crossover
  • Effects unit — reverb, delay
  • Wireless microphones — handheld and lavalier, quantity set by the number of people on stage
  • Antenna distribution and antennas — essential in large rooms, otherwise wireless mics drop out
  • Sound engineer and loaders — priced per person, often omitted
Common trap

"Antenna distribution" and "antennas" are the two items most often cut. In a small room you won't notice — at a few hundred people and tens of metres, wireless mics start dropping out and picking up noise. If the quote doesn't list these two, ask.

Lighting: judge by console grade

The quickest way to read a lighting tier is the console:

  • Small — simple console, basic illumination and simple effects
  • Medium — MA-series console, programmable, multiple scene changes
  • Large — Grand MA2-class console, complex light shows, independent multi-zone control

For fixtures, the common mix is PAR cans (wash), moving beam heads (dynamic effects), gobo lights (pattern projection) and key/front light (lighting the people on stage). Whether the front light is a cool source matters a great deal — a hot source shifts colour on camera and makes faces look yellow.

03LED screens: priced by usage, but the ancillaries are the real cost

LED screens are priced per square metre, but the panel is not what drives the total on its own.

ComponentPriced byWhat to check
Screen panelsm²Pixel pitch P2.5 / P3 / P4 — finer is sharper and dearer
Video processorUnitEssential for switching multiple sources
Splicing processorUnitEssential for large or multi-screen walls
TechnicianPersonOn-site setup and troubleshooting
Structural supportItemTimber base, ballast, support frames
Supporting TV / monitorsUnitConfidence monitors, vision-mix monitoring
Cabling and signal transmissionItemLong runs need signal amplifiers
When checking the price

Ask "what does this per-square-metre price include?" The usual trap: the unit price covers only the panels, with structure, processors and technicians billed separately — together they can cost as much as the screen itself.

04Four things to confirm before load-in

Each of these is on our pre-load-in self-check list. Miss one and something can go wrong on site.

① Venue survey

  • Verify dimensions — don't trust drawings, measure on site
  • Walk the access route — can the equipment get in, what can the lift carry
  • Equipment positions — where speakers hang, where truss stands, where the console sits
  • Power load and connections — where the distribution points are, who connects, how much cable is needed

② Coordinate with technical

  • Installation sequence for projection screens, LED, LED drapes and TVs — what goes first
  • Whether the factory needs to pre-build brackets, load platforms, cut-outs, edge trims or risers
  • Who runs power to each equipment position
  • Whether video and PPT drafts have been sent to the technical team in advance for testing

③ Prepare all media

  • Music: leader's entrance, awards, pre-show warm-up, post-show exit, prize draws
  • Video: countdown, LED drapes, warm-up loops, performance cues
  • Hand all media to the technical team a day early to test-play — never play it for the first time live

④ Power assurance

  • Power must come from the main distribution board, with lighting, sound and LED on separate circuits
  • Confirm the load is sufficient; never power lighting and sound from wall sockets
  • Route all cables neatly and protect them to prevent trips and crush damage

05On-site verification: check by stage

AV verification is not a glance before doors open — it happens in stages.

During installation: check safety

  • Leakage tested?Confirm every distribution board is not overloaded
  • Lighting truss and LED secure?Safety cables fitted, supports adequate, spans within load
  • Cables exposed?Fire precautions in place, fixtures locked so they cannot fall
  • LED backup?Spare cabinets recommended for critical areas

Before rehearsal: check the list

  • Materials checklistWireless and wired mics, stands, lavaliers, music drives all present, with enough batteries
  • Playback equipmentPlayback laptops, switcher, DVD, video interface cables all ready
  • Comms systemInternal intercom fitted so vision mix, lighting and sound can talk in real time

Before rehearsal: check lighting

  • Multi-scene testPre-show, video playback, performance, leader's entrance — run each scene
  • Front light checkIs the podium lit, and is the source cool-toned
  • Avoid screen spillNo light hitting the projection screen or LED wall and washing out the image
  • LOGO projectionFollow spots and LOGO lights working, projection position accurate
  • Backdrop fillAreas of backdrop that need lifting are lit
