Conference AV Production: What Your Technical Team Needs to Deliver

The most common problem in conference production is not equipment failure. It is a spec that was too thin to begin with. The PA cannot cover the back third of a 400-person room. The screen is too small for anyone beyond row six to read a slide. The radio mics are not the right type for a speaker who moves around the stage.

These are not surprises that happen on the day. They are consequences of decisions made weeks before. This guide runs through each component of conference AV in enough detail to brief a production company properly and understand what you are buying.

The stage is the first thing the room sees when doors open. It sets the level of the event before a word is spoken. For most conferences, this means a platform or raised stage, a lectern, and some kind of backdrop or visual frame.

• ✓Stage height — For audiences of 100 or more, a platform of at least 600mm is typically needed so people beyond the front rows have a sight line to the speaker. Higher stages need steps on both sides, not just one.
• ✓Stage depth and width — A panel of five people needs more stage depth than a single keynote speaker. Measure from the front edge to the backdrop, not just the width.
• ✓Backdrop and surround — Fabric backdrops, LED walls, printed panels or branded screens. The choice affects the whole production budget and needs to be made early because it determines rigging requirements.
• ✓Lectern and podium — Confirm whether a corporate-branded lectern is needed or whether a clean, unbranded option works. Branded lecterns are fabrication items. Budget accordingly.

This is the question that most conference briefs leave open too long. LED walls and projection are not interchangeable. Each suits different conditions.

Sound quality is the element audiences notice most when it fails and least when it is right. The PA specification should match the room size, shape and ceiling height — not simply the delegate count.

• ✓Line arrays versus point source — For rooms above 300 people or with complex shapes, line arrays provide more even coverage. Point source systems (single cabinets with fills) work at smaller scale and in rooms with low ceilings where line arrays cannot be correctly positioned.
• ✓Radio microphones — Handheld, lapel or headset. The choice depends on how the speaker moves and what they are wearing. Lapels on fast-moving presenters lose audio quality. Headsets are better for those who gesture widely. Handhelds work for panels where mics are passed.
• ✓Delegate floor mics for Q&A — If audience Q&A is part of the programme, confirm whether roving mics are used (requires a crew member to manage) or fixed floor mics are positioned in the auditorium.
• ✓Hearing loop — Required under the Equality Act for public events. For corporate conferences, confirm whether the venue has a fixed loop or whether a portable system needs to be provided.

Confidence monitors are screens positioned on the stage floor or front of stage facing the speaker. They show the current or next slide, the run of show, and sometimes a clock. They are not optional for speakers who are not carrying notes.

• ✓Current slide view — The speaker needs to see what the audience sees without turning to face the screen behind them. A monitor positioned in their sightline, below eye level, handles this.
• ✓Next slide preview — Some speakers require a two-monitor setup: current slide and incoming slide. Confirm this with the presenter in advance, not during rehearsal.
• ✓Countdown clock — Particularly important for external keynote speakers working to a hard finish time. Usually driven from the presentation operator's station.
• ✓Position for the presenter's working pattern — A presenter who stands behind a lectern needs monitors in a different position to one who walks the full stage width. Floor positions need to be confirmed against stage layout before load-in.

Recording and live streaming are separate technical operations that are often assumed to be included in a conference AV package when they have not been specifically scoped. Both need to be in the brief.

• ✓Single-camera versus multi-camera recording — A single camera on stage captures the speaker. Multi-camera adds wide shots, audience reaction and presentation content cuts. The latter requires a video director and a switching desk.
• ✓Clean audio feed for recording — The recording must take a feed from the mixing desk, not the room audio. This is a technical patching requirement that needs to be confirmed with the sound engineer.
• ✓Live streaming encoder and operator — Streaming to a platform (Teams, YouTube, Vimeo Live, etc.) requires an encoder, a stable dedicated upload connection and an operator who manages the stream independently of the live show. This is a separate crew position.
• ✓Post-production deliverables — If the recording will be edited and distributed after the event, agree the format, resolution and turnaround in the initial brief. Last-minute requests for specific exports are costly and slow.

For most conferences, lighting serves two purposes: making the stage visible and making the room look good on camera. The two requirements do not always point to the same solution.

• ✓Stage wash and key lighting — A clean key light on the presenter's face is essential for live recording. Flat stage wash from a single direction creates unflattering shadows on camera even if it looks adequate to the live audience.
• ✓Room uplighting and ambience — Branded colour washes in the room around the perimeter elevate a conference from functional to produced. LED uplighters on stands require no rigging and can be positioned to work around venue restrictions.
• ✓Show control integration — For conferences with multiple sessions, pre-set lighting states that change between sessions (panel lighting, keynote lighting, break mode) reduce operator workload and create a more consistent experience across the day.
