AV for events in churches and cathedrals is some of the most rewarding and most unforgiving work we do. A cathedral is one of the most beautiful places you can ever put on an event, and one of the most unforgiving places to get the AV right. The same stone that makes a choir soar will turn a careless mix into a wall of echo, and the building will not bend to suit you.
We work events in churches, minsters, and cathedrals regularly, including Chester Cathedral, York Minster, St Patrick’s Cathedral in Dublin, and the Wexford Opera House. Here are the challenges that nobody mentions until you are standing in the nave with an hour to load in.
First, a clarification: events, not installations
It is worth being straight about this. We do not install permanent sound systems in churches, because church installation budgets are typically too low to do the job properly, and I would rather be honest than take on work I cannot do well.
What we do is deliver events in these buildings: a concert, a service, a performance, a special occasion, where we bring production in for the day and take it away again. That is a different discipline, and it has its own set of challenges.
The acoustics fight back
The defining feature of these spaces is reverberation. The room is gloriously live, and that is exactly the problem.
The natural echo that makes a building like this feel sacred is the same echo that destroys clarity the moment you push too much volume into it. Over-amplify and speech and music dissolve into mush. So you work with the acoustics rather than against them, placing and mixing carefully so every word and note stays clear while the natural atmosphere of the building stays intact. Every one of these venues behaves differently, so you read the space and adapt.
This is closely related to the work behind live choral AV, where the building genuinely becomes part of the instrument.
The practical rules you cannot break
Beyond the sound, historic buildings come with hard constraints, and they are not suggestions.
Access time is usually extremely limited. Load-in and load-out windows are tight, so everything has to be planned to the minute. The approach is often across cobbles, which makes moving heavy equipment slow and awkward. And critically, you cannot tape cables to the floor, so you use cable mats instead.
On top of that, there are restrictions on where you can place anything, and strict rules about what you can and cannot do to the fabric of the building. You do not improvise in a cathedral. You plan around its rules, respect them completely, and that is part of why these places trust the companies they let in.
Why experience is the whole point
None of this is learnable on the day. You either know that the load-in is tight, that the cables go on mats, that the mix has to fight a three-second reverb tail, and that the building has the final say, or you find out the hard way in front of an audience.
Having worked these spaces for years, the planning is second nature now. That is what lets an event in a stunning, difficult building look and sound completely effortless, which is exactly how it should look from a pew.
Frequently asked questions
What makes AV in churches and cathedrals difficult?
Highly reverberant acoustics that need careful mixing, very tight access and load-in windows, and strict rules about a historic building. You cannot tape cables down, so you use cable mats, and placement is often restricted.
Does PSL install sound systems in churches?
No. Church installation budgets are typically too low to do the work properly. We deliver events in churches, minsters, and cathedrals instead.
How do you handle the acoustics of a cathedral?
You work with the reverberation rather than against it, placing and mixing so clarity holds while keeping the natural atmosphere.
Which cathedral venues has PSL worked in?
Chester Cathedral, York Minster, St Patrick’s Cathedral in Dublin, and the Wexford Opera House, among others.
