Audio Visual Requirements: A Planner’s Guide for 2026

You're usually asked for an AV list far too early.

A planner books the venue, confirms the running order, and then someone asks, “What are the audio visual requirements?” At that point, many teams start naming kit. A lectern mic. Two confidence monitors. A projector. Maybe a livestream. That's the wrong starting point.

Audio visual requirements are really a communication plan. The equipment comes later. First, you need to know what the room allows, what the audience needs to hear and see, how the content will be delivered, and who has to operate it. Get those decisions right and the kit list becomes logical. Get them wrong and even expensive equipment can still fail on the day.

Starting with the Space and the Audience

Before you choose a single screen or microphone, assess the room and the people who'll use it. Most AV problems begin here, not at the hire stage.

A boardroom presentation, an awards dinner and a hybrid town hall might all happen in the same venue, but they have different audio visual requirements because the viewing angles, sound coverage, presenter movement and audience expectations are different. The venue doesn't just hold the event. It shapes the technical solution.

What to check on a site visit

Walk the room as if you were an attendee, not just an organiser.

• Room dimensions: Measure width, depth and ceiling height. A low ceiling limits rigging and projector positioning. A deep room changes screen sizing and speaker coverage.
• Sightlines: Sit at the back, the sides and behind structural obstructions. Columns, chandeliers and low truss points regularly block screens.
• Ambient light: Check windows, skylights and practical house lighting. Projection that looks acceptable during a dark site visit can wash out completely in daylight.
• Ambient noise: Listen for HVAC, nearby traffic, bars, kitchens and adjoining breakout rooms. Speech reinforcement has to overcome all of that cleanly.
• Access routes: Identify load-in doors, lifts, stairs and distance from the loading bay. Practical access affects setup time and what can realistically be installed.
• Venue rules: Ask about hanging points, noise limits, cable routes and engineer call times.

If you're still comparing rooms, a proper London venue guide helps narrow down spaces that are more technically workable before you commit.

Practical rule: If the room hasn't been measured, lit and listened to, the AV spec is still a guess.

Screen and projection decisions

Visuals fail when planners start with resolution and ignore the room. For medium-to-large spaces, one useful benchmark is a 7000 ANSI-lumen, laser, 4K-capable projector, with the workflow handled in this order: measure ambient light, determine throw distance, select lens, confirm screen aspect ratio, then size brightness. Specifying resolution first is a common mistake, as noted in projection system design guidance.

That order matters because a sharp image nobody can see is still a bad result.

For presentation-heavy events, check:

1. Whether the audience needs one main screen or image support screens.
2. Whether content includes spreadsheets, small text, detailed graphics or video.
3. Whether presenters will stand in front of the screen.
4. Whether the room can be darkened without affecting audience comfort or safety.

Sound is coverage, not volume

Many new planners ask, “How many speakers do we need?” The better question is, “Will every seat hear speech clearly?”

A keynote in theatre seating needs even speech intelligibility across the room. A panel discussion needs consistent coverage plus enough microphone channels and careful management of overlap. A workshop might need lower overall level but better control of audience questions and local playback.

Room shape matters as much as audience size. Long narrow spaces, hard reflective walls and low ceilings can all make speech harder to understand. In practice, the requirement isn't loud sound. It's clear, controlled sound in the seats that matter.

Translating Event Goals into an Equipment List

Once the room is understood, turn the event brief into functions. That's when an AV list starts to make sense.

Today's event setups are rarely a loose collection of standalone items. The wider market has moved towards integrated systems, and that's reflected in event delivery. The global audio visual hardware market was valued at USD 256.53 billion in 2023, rising to USD 272.27 billion in 2024 and projected to reach USD 389.21 billion by 2030, representing a 6.1% CAGR from 2024 to 2030, according to Grand View Research's audio visual hardware market report. For planners, the practical meaning is simple. Modern audio visual requirements usually involve sound, displays, switching, cabling, control and often streaming working together.

If you need a plain-language breakdown of the categories involved, this guide to audio visual equipment is a useful reference point.

Match the format to the hardware

A keynote speech has different technical needs from a panel, product launch or internal broadcast.

• Keynote session: lectern microphone, clicker, presentation laptop support, confidence monitor, main screen feed, lectern light if notes are used.
• Panel discussion: multiple radio handhelds or lapel microphones, moderation mic, audio mixing, timer display, walk-on music playback if needed.
• Brand video reveal: playback machine, screen or LED display, proper audio playback path, show control cueing.
• Hybrid meeting: room microphones, PA, in-room display, camera feeds, switching, streaming encoder and return audio management.
• Awards segment: cue lights, walk-up music, winner sting playback, stage monitors, showcaller communications and content backup.

The mistake is to order by item name instead of event purpose. “Two screens and four mics” isn't a specification. It's an incomplete shopping list.

Think in signal chains

Every requirement should be traced from source to destination.

For audio, that means asking:

• where the voice starts
• how it's mixed
• where it's heard
• whether it also needs to go to recording or stream

For video, ask:

• where content originates
• what format it arrives in
• who switches between sources
• where it's displayed
• whether it also needs to feed a stream or overflow room

A reliable event system is one where every signal path has been agreed before load-in.

That's why mixing consumer gear into a professional setup often creates problems. A single personal adapter, unmanaged laptop output, or domestic playback device can trigger format mismatches, HDCP issues, unreliable switching or last-minute scrambling at the tech desk.

Creative ideas need technical translation

A planner might say, “We want the CEO to feel close to the audience.” Technically, that could mean IMAG cameras, side screens, a roaming handheld for audience Q&A, and a stage layout that keeps the presenter clear of the main projection beam.

A client might say, “We want it to feel premium.” That usually doesn't mean adding random equipment. It means clean screen design, proper show cueing, balanced lighting, well-managed walk-on audio and no visible technical chaos.

A short explainer is often easier to show than to describe in abstract terms:

Good AV planning turns vague creative language into technical actions. That translation stage is where many expensive mistakes are prevented.

Planning for Power Rigging and Connectivity

The most polished equipment list still fails if the infrastructure underneath it is weak.

In professional AV planning, infrastructure is now treated as a baseline requirement rather than an optional add-on. Design standards for AV-ready rooms commonly include dedicated data ports, duplex power outlets and cabling conduits, which reflects the wider shift from plug-and-play setups to infrastructure-led planning, as outlined in AV room design standards.

That same mindset applies on event day. If the room doesn't have the right power, rigging points or data access, the brief has to change.

Power first, always

Wall sockets are often the most misleading part of a venue recce. A room may look well served, but those outlets might be shared with catering, house lighting, registration desks or other spaces.

Check these points early:

• Socket location: Are outlets where stage, screen, control and camera positions need them?
• Circuit separation: Can critical AV run on circuits that won't be interrupted by other users?
• Distribution routes: Is there a safe path for temporary power distribution without crossing audience walkways?
• Backup thinking: Which elements are mission-critical, and what happens if one feed fails?

A dedicated power drop means power has been intentionally allocated for event use, not borrowed from whatever happens to be nearby. That distinction matters.

Rigging has to be planned, not improvised

Any equipment suspended above people needs proper approval, correct hardware and competent installation. That includes projectors, truss, lighting bars, speakers and LED elements.

Ask the venue:

• what can be hung
• where it can be hung
• who signs it off
• what access equipment is permitted
• when the room is available for installation

Don't assume a ballroom ceiling can carry production loads just because it has decorative points or existing fixtures.

Rigging problems rarely appear as small inconveniences. They usually force a redesign.

Connectivity for hybrid and streamed events

For hybrid events, connectivity should be specified like any other technical input. Relying on guest Wi-Fi for a webcast is asking for instability.

Use hardwired internet where possible, and define exactly what the connection is for:

• stream uplink
• presenter demo access
• remote speaker contribution
• production comms
• attendee access

If you're planning webinars or streamed sessions, this guide on good upload speeds for webinars is a useful reference for discussing connection expectations with venues and IT teams.

For more involved live and remote formats, a dedicated hybrid streaming setup should be treated as part of the core event design, not an add-on after the room layout is fixed.

Documenting and Communicating Your AV Brief

Most AV problems on live events can be traced back to ambiguity. The planner thought one thing. The venue assumed another. The supplier priced a third.

A proper AV brief removes guesswork. It doesn't need to be overly technical, but it does need to be organised, specific and complete enough that another team can turn it into a working plan.

What the brief must include

Start with the event basics. These seem obvious, but they're often missing or scattered across emails.

Include:

• Event name and date
• Venue name and exact room names
• Access times, live times and de-rig times
• Audience format, such as theatre, cabaret, classroom or standing
• Running order with timings
• Key contacts, including venue operations, IT, catering and event lead
• Presenter details, especially remote contributors or high-profile speakers
• Known venue restrictions, such as noise limits, rigging limits or late access

Then document each room separately. Don't bury breakout room requirements inside a main plenary note.

Write requirements by function

The strongest briefs describe what each system has to do.

Bad brief:

• One projector
• Some mics
• Video support

Better brief:

• Main screen to show keynote slides, panel titles and playback video
• Lectern speech reinforcement for plenary audience
• Four radio microphones for panel, plus audience Q&A handheld
• Confidence monitor visible from stage left
• Camera feed to relay speaker image to side screens if required

That style gives the technical team room to propose the right method without guessing your intent.

Working advice: If a requirement matters on show day, it should exist in the written brief, not only in someone's head.

Sample AV Specification Template

Keep one version of the truth

The brief should be shared as a single working document. If the stage plan is updated, the AV brief, show flow and venue notes should all reflect that change.

Version control matters more than people think. Last-minute edits are common in corporate events. The problem isn't change itself. The problem is when lighting, sound, video and venue teams all work from different assumptions.

A calm project starts with clean documentation.

Budgeting for Equipment and Expert Crew

Planners often try to save money by cutting crew before they cut scope. That's usually the wrong decision.

Equipment doesn't operate itself. A well-built system still needs people to install it safely, line-check it, test content, manage cues and solve problems before the audience notices them.

Where the budget really goes

An AV budget usually includes several layers:

• equipment hire
• transport
• setup and de-rig labour
• on-site operating crew
• project management
• venue-specific access or compliance costs

The crew line matters because each role protects a different part of the show. A sound engineer manages microphones, playback and speech clarity. A video technician handles screens, switching, playback and display routing. A project manager coordinates the overall plan, paperwork, venue liaison and timing.

If one person is trying to do all of that on a complex event, something will be missed.

Value is in stability

Cheaper equipment lists often look attractive because they omit the people and prep that make them reliable.

That's where experienced support becomes worth the cost. For example, London Audio Visual Hire provides AV hire and event production support for conferences, launches, awards and hybrid events, which is useful when a planner needs equipment, crew and technical coordination handled together rather than split across separate suppliers.

A professional crew also protects the schedule. If a presenter arrives with the wrong connector, a video file won't play, or a radio mic has to be reassigned quickly, the response time on site matters more than the line-item savings on paper.

Right-size the system

There's also a sustainability argument for disciplined budgeting. In the UK, planners are increasingly expected to justify energy use, and AV planning is part of that. AVIXA's needs assessment guidance supports the idea that the better question is often the minimum effective specification, rather than assuming more kit is always better, because oversized systems can increase power draw and cost without improving the outcome, as discussed in AV needs assessment guidance.

That applies to budget control as much as environmental thinking. The right system is the one that delivers clarity, reliability and accessibility without unnecessary excess.

Avoiding Common Pitfalls and Ensuring Accessibility

A technically functional event isn't automatically a professionally delivered one.

Many teams still treat accessibility as a final check or a separate service request. In practice, it should be part of the audio visual requirements from the start. Under the Equality Act 2010, planners need to make reasonable adjustments, and for AV that means considering measures such as live captioning, hearing-loop compatibility and audio description, as reflected in guidance on integrated audio-video systems and accessibility.

The problems that catch teams out

Some failures are very ordinary:

• presenters arrive with untested laptops
• embedded videos have no audio path
• adapters are missing
• cable routes create trip risks
• no backup microphone is ready
• nobody has viewed the deck from the back of the room

Those are planning failures, not equipment failures.

Accessibility failures are similar. A stream may work perfectly while excluding attendees who need captions. A stage may look clean while offering poor sightlines for wheelchair users. A speaker may be audible in room but unintelligible to a hearing-loop user if that path was never tested.

Functional AV is the minimum. Professional AV is reliable, readable and inclusive.

Ask better questions before sign-off

Before approving the brief, ask:

• If the main presenter's laptop fails, what is the fallback?
• If a remote guest drops out, what changes in the running order?
• If audio becomes unclear, what visual support remains available?
• Can every attendee reasonably access the content?
• Do you need interpretation as well as captioning for multilingual audiences?

For events with multiple languages or international delegates, a specialist 2026 event interpretation guide is a helpful companion when interpretation has to sit alongside the wider AV plan.

If you're defining audio visual requirements for a conference, awards night, launch or hybrid event, London Audio Visual Hire can help turn an outline brief into a workable technical plan. The useful point early on isn't just what kit to hire. It's whether the room, agenda, audience and infrastructure all support the result you need.
