Church conventions are among the most demanding events we cover, and among the most under-planned. A wedding lasts an evening; a convention can run for days, with worship bands, multiple preachers, crowds that exceed the venue's capacity and a congregation that fully expects to hear every word. Here is what actually needs thinking through.
Plan for the crowd that turns up, not the one that RSVPs
Conventions routinely draw more people than expected, and the overflow ends up in the grounds, under marquees or standing outside the doors. If the sound system was specced for the hall only, those people hear nothing. Decide in advance whether overflow areas will be covered with additional speakers, and budget for it — retrofitting coverage while a service is in progress is not practical.
Worship teams need a different setup to preaching
A preacher needs one clear voice reaching everyone. A worship team needs multiple vocal microphones, instrument inputs, keyboards, drums and — crucially — stage monitors so the musicians can hear themselves. Without monitoring, singers push harder, drift off pitch and the whole band gets progressively louder. Many convention sound problems are actually monitoring problems that show up as front-of-house problems.
Multiple speakers, multiple microphones
Conventions involve a lot of handovers — a worship leader, an MC, visiting preachers, testimonies from the congregation. Each handover is a chance for a microphone to be muted, dropped or fed back. Plan enough wireless channels that people are not passing one microphone around, coordinate the frequencies properly, and have the technician manage muting rather than leaving it to whoever is holding the mic.
The room is usually working against you
Large halls, school assembly rooms and community centres tend to be acoustically hard — bare walls, high ceilings, tiled or concrete floors. Speech echoes and becomes hard to follow, especially at volume. This is not solved by turning up; it is solved by speaker choice and placement that directs sound at the congregation rather than at the walls. A supplier who has seen the room, or at least photographs of it, can plan for this.
Multi-day means installed, not rebuilt
For a convention running several days, the rig should be installed once and left in place with a technician present for each session — not built and struck daily. That saves cost, reduces the risk of something being wired differently on day three, and means each session starts on time. Confirm overnight security arrangements with the venue as part of the plan.
Streaming reaches the members who cannot travel
Conventions draw congregations from across the country and the diaspora, and many members cannot attend in person. Streaming the sessions — with audio taken from the mixing desk, not a camera microphone — extends the convention enormously. Recordings of each session are also valuable afterwards, both for members and for the church's own archive.
Power, over several days
Load shedding over a multi-day programme is close to a certainty rather than a risk. A standby generator sized for the full rig keeps sessions running, and battery backup on the desk and streaming equipment prevents a brief interruption from dropping the broadcast. Factor fuel for the whole convention, not just one day.
Talk to your supplier early
The single biggest improvement you can make is involving the AV supplier while the programme is still being planned rather than the week before. Session structure, expected numbers, whether there is a band, where overflow will go and how long each day runs all change what is needed.

Frequently asked questions
How do we cover people who cannot fit inside the hall?
With additional speakers serving the overflow areas — grounds, marquees or adjacent rooms. This needs deciding and budgeting in advance, because it cannot practically be added while a service is running.
Why does the worship band always end up too loud?
Usually because the musicians cannot hear themselves. Without proper stage monitoring, singers and players push harder to compensate and the whole band creeps louder. Fixing monitoring usually fixes the volume.
Should the equipment stay set up between days?
Yes, for multi-day conventions. Installing once and leaving the rig in place is cheaper, more reliable and means every session starts on time. Agree overnight security with the venue.
Can convention sessions be streamed and recorded?
Yes. We stream and record sessions with audio taken directly from the mixing desk, so remote members and the church’s own archive get clean, intelligible audio.
