We do the sound for Johns’ Boys, who are probably the largest male voice choir in the UK right now. They were on Britain’s Got Talent a few years ago, and these days they sell out everywhere they go: York Minster, Chester Cathedral, St Patrick’s Cathedral in Dublin, the Wexford Opera House, theatres in London, Edinburgh, Salisbury.

Those are some of the most beautiful and most difficult rooms in the country to put sound into. So when people ask what live choral AV actually involves, the honest answer is that it is one of the more demanding things we do. Here is why.

A choir is not a band

A choir presents a completely different problem from a rock band. You are not reinforcing a handful of instruments, you are capturing a large group of voices and making them clear and natural for an entire audience, without the result sounding harsh or artificial.

Done well, the audience should barely notice the sound system at all. They should just hear the choir, full and balanced, whether they are in the front row or right at the back. Getting there takes a careful, restrained approach, because the moment a choir sounds processed, you have lost what makes it special.

The building is part of the instrument

Here is the thing that makes cathedrals and minsters so hard: they are extraordinarily reverberant. The room itself is part of the sound, and it does not always cooperate.

In a space like that, the natural echo that makes a choir sound glorious is the same echo that can turn the words to mush if you over-amplify. The skill is working with the acoustics rather than fighting them, placing and mixing so the clarity holds without killing the atmosphere the building gives you for free. Every venue behaves differently, so you read the room and adjust.

The practical challenges nobody sees

Beyond the mix, these venues come with real practical constraints, and you respect them or you do not get invited back.

Access time is usually very tight, so load-in and load-out have to be planned to the minute. You cannot tape cables to the floor in a historic building, so you use cable mats instead. There are restrictions on where equipment can go, and strict rules about what you can and cannot do to the fabric of the building. None of this is negotiable, and a company that turns up not knowing it causes problems immediately.

For more on this side of the work, we have written separately about working events in churches and cathedrals.

Why these relationships last

The choirs we work with tend to stay with us for years. Johns’ Boys are one. Belle Voci, who appeared on The Voice, are another, and they feel like family, they come to us and go nowhere else.

There is a practical reason behind the warmth. A choir that sounds right one night and wrong the next has a problem, and consistency across very different venues is hard to achieve unless the same people travel with them and know the choir’s sound. When a choir trusts a company to get it right in York Minster one week and a Dublin cathedral the next, that trust is worth holding onto on both sides.

That is the part of live choral AV that does not show up in a kit list. It is knowing the choir, knowing the rooms, and being the steady hand that makes a sold-out cathedral sound effortless.

Frequently asked questions

What does live choral sound engineering involve?

Capturing and reinforcing a choir in spaces that are often highly reverberant, like cathedrals and minsters, making a large choir clear and natural for the whole audience without losing the character of the room.

Why are cathedrals difficult for live sound?

They are extremely reverberant, access time is tight, and there are strict rules on the building. You cannot tape cables down, so you use cable mats, and equipment placement is often restricted.

Do you provide sound for choirs across the UK?

Yes, at venues including York Minster, Chester Cathedral, St Patrick’s Cathedral in Dublin, and the Wexford Opera House.

Why does the same sound company travel with a choir?

For consistency. A company that knows the choir brings the same sound from venue to venue, which is why our choral relationships tend to be long-term.

The first question I ask any outdoor festival client is not about speakers at all. It is: what is your wet weather plan?

That tends to surprise people. But choosing a PA system for an outdoor festival is never just about the size of the PA. It is about the field, the crowd, the power, the weather, and the budget, all pulling against each other. Get the thinking right and the right size of system becomes obvious. So here is how we actually work it out.

Start with two numbers: capacity and area

There are two questions that begin every festival quote. How many people are you expecting, and how big is the area you want to cover?

Those two numbers almost never line up neatly, and that is where the useful conversation starts. Two hundred people at a tight stage is a very different job from two hundred people spread across a large field, even though the headcount is identical.

Capacity or area: the conversation that saves you money

When capacity and area do not match, I put the choice plainly to the client.

We can cover the entire field, but then the pricing reflects the area, not the number of people. Alternatively, we can price for the capacity. If you are expecting 200 people and someone chooses to stand 50 metres from the stage, is it reasonable to expect them to move a bit closer? If it is, we use a smaller system and the price comes down.

That is a real conversation we have, and it is an honest one. There is no point selling a festival a system built to flood an empty field. Matching the system to how the crowd will actually gather is usually where the biggest saving lives.

The type of act changes everything

A local act and a headline act are not the same specification, even on the same field. The energy, the volume, the low end, and the expectations all shift with the bill.

A community stage with acoustic acts has different needs from a stage built around a headliner the whole site has come to see. We spec for the act as much as for the field.

Why we use line arrays outdoors

For outdoor events we always prefer line arrays over point source speakers. Ours are active and weather protected, which matters in a British field, and they throw sound evenly across a large area in a way point source boxes cannot.

For the subwoofers, there are three main ways we set them up: an end-fire array, a straight line across the front of the stage, or a left and right stack. Which one we choose depends on the type of music, the coverage we need, and the power budget available. Bass-heavy music in a wide field is a different decision from a folk stage in a smaller space.

To give a sense of the range: a smaller event might use single 18-inch subwoofers with the line array tops ground-stacked. A large one might run up to twelve twin 18-inch subwoofers, with two line array hangs of eight boxes each, flown above the stage. The same company, very different rigs, driven entirely by the brief.

The four things that decide it all

In the end, four variables decide the system: the capacity, the size of the field, the power budget, and the financial budget. Change any one of them and the answer changes.

Power itself is rarely the problem. We have good relationships with local power companies, so getting clean power to where it needs to be is usually straightforward.

The honest budget conversation matters more. If you expect Wembley but I quote for a local pub, you will not be happy with the outcome. If you want a local event but I quote for Wembley, you will not be happy with the quote. Telling me the real budget early gets you the right system, not the wrong one.

For more on the practical side of running these events well, see our guide to outdoor event production in North Wales.

Frequently asked questions

How do you work out what size PA an outdoor festival needs?

We start with the estimated capacity or ticket numbers and the size of the area to be covered. Those rarely match, so the next conversation is whether to cover the whole field or price for the crowd you actually expect.

Why does covering the whole field cost more?

Because the system is priced for the area, not the headcount. Often it is reasonable to expect the crowd to gather closer, which means a smaller system and a lower price.

Are line arrays better for outdoor events?

For outdoor events we always prefer line arrays over point source speakers. Ours are active and weather protected, and they throw sound evenly across a large area.

What is the first thing to plan for an outdoor festival?

The wet weather plan. It shapes the equipment, the cover, the power, and the layout.

Outdoor event production in North Wales lives and dies by the things people do not see. The speakers get the attention, but it is the weather plan, the ground, the access, and the power that decide whether the day actually works.

We do a lot of outdoor work across North Wales, from fields and fun days to festivals, and the pattern is always the same. The production thinking happens long before anyone hears a note. Here is what that looks like.

Weather comes first, always

The first thing we plan for is the weather, because in this country it is the one thing you cannot argue with. The very first question I ask an outdoor client is what their wet weather plan is, and it shapes everything that follows.

It is not only rain, either. A British day can be hot and sunny at 2pm and drop to six degrees by 10pm. That matters more than people expect, because sound behaves differently in hot air than in cold, and humidity changes it again. The mix that sounds right in the afternoon will not sound the same once the temperature falls, so the team has to plan for the sound to shift across the day, not set it once and walk away.

For the equipment itself, this is part of why we use line arrays outdoors, and why ours are active and weather protected. Kit that can handle a wet field is not a luxury here, it is the baseline.

Ground, access, and getting everyone out safely

After the weather, the next things we look at are the practical realities of the site. What are the ground conditions? How do we get equipment in, and how do people get in and out safely?

Access and egress sound like dull words until the day a heavy load has to cross a soft field, or a crowd needs to leave quickly. Planning the routes, the load-in, and the load-out properly is a large part of what production actually is. The kit list is the easy bit by comparison.

Power is usually the easy part

Power worries clients more than it should. In practice it is one of the more straightforward elements of an outdoor event for us.

We have good working relationships with local power companies, so getting clean, reliable power to where it needs to be is rarely a problem. It still needs planning early, but it is not the thing that keeps me up the night before a show.

Coverage and budget have to be honest with each other

How much of the area you cover comes down to budget, and the two do not always match the size of the field.

A festival with a capacity of around 4,000 people usually has the budget to cover a large area properly. A smaller event might have the same physical footprint but a much smaller budget, which means coverage has to be prioritised and some honest compromises made. The space and the money are not always in step, and the job of a good production company is to be straight with you about that rather than overselling.

If you want the detail on how we actually size the PA itself, we have written a separate guide on what size PA system you need for an outdoor event.

A local company for local fields

Being based in Llay, Wrexham, we know the ground around here, and our work takes us right across North Wales and well beyond. Knowing the region, the venues, and the weather is a quiet advantage. We have seen what these fields do in the rain, and we plan accordingly.

That local knowledge, paired with proper kit and an honest budget conversation, is what makes an outdoor event feel effortless to everyone watching. The effort all happened before they arrived.

Frequently asked questions

What are the biggest challenges of outdoor event production?

Weather is the number one challenge, which is why the wet weather plan comes first. After that it is ground conditions, access and egress, power, and how much of the area you need to cover.

Is power a problem for outdoor events?

Rarely. We have good relationships with local power companies, so clean power is usually straightforward. It needs planning early, but it is not the thing that causes problems.

Why does outdoor sound change through the day?

Temperature and humidity affect how sound travels. A day can be hot at 2pm and six degrees by 10pm, so the afternoon mix will not sound the same at night, and the team accounts for that.

Do you cover outdoor events across North Wales?

Yes. We are based in Llay, Wrexham, and provide outdoor event production across North Wales and the wider UK.

People ask me what separates a good live sound company from a bad one. The honest answer is that I wouldn’t know, because I only work with good companies.

That is a joke, but there is a serious point underneath it. Whether you are booking a live sound company in North Wales or hiring a touring crew anywhere, the same checks apply. After years in this industry you learn to spot a properly run operation within the first phone call, and you learn to spot a cobbled-together one just as fast. If you are a band manager, a promoter, or anyone responsible for booking sound for a show, you can learn to spot the difference too.

Here is the checklist I would run through before handing anyone your gig.

Do they ask the right questions before they quote?

A good live sound company asks about access and power before it gives you a price. How does the equipment get in? What power is available on site? These things shape the whole job.

If a company is happy to hand over a kit list and a number without asking anything about the venue, that tells you something. They are quoting a guess. The right questions come first, the price comes after.

Can they give you a kit list in advance?

A professional company can tell you exactly what it is bringing before the day. If they cannot, they are not properly organised.

Ask for it. A clear kit list is one of the simplest signs that a company plans its work rather than improvising it on the morning.

Do the equipment brands actually match?

This one is a quiet giveaway. If you see JBL subwoofers paired with Mackie tops, that tells you straight away it is a cobbled-together budget rig.

A coherent, professional system uses matched equipment that is designed to work together. If the brands do not belong with each other, ask why. There is sometimes a good reason, but more often it means the kit has been assembled on price alone.

Are they providing proper paperwork?

This is where the serious companies separate themselves from the rest. Ask whether they provide a few key documents.

• CDM documentation. CDM stands for Construction Design and Management, the formal safety framework that governs how professional event production companies plan and manage risk. A company without it is not operating to professional standards.
• Risk assessments and method statements. These show they have thought about what could go wrong and how they will handle it.
• Plans. A stage plot, a system diagram, and a site plan. A company that works to drawings is a company that knows what it is doing before it arrives.

If a supplier cannot produce these, that is not a small gap. It is the difference between a professional operation and an amateur one.

Have they offered a site visit?

For anything beyond the simplest show, a good company will want to see the space, or at least assess it properly based on the scale of the job. A site visit is where the real problems get spotted early, before they become problems on the day.

Have you actually spoken to them on the phone?

A company you can only ever reach by email or text is a concern. Live production runs on quick, clear communication, and you want to know there is a real person who picks up when something needs sorting.

Have you seen their insurance?

Ask for it. A professional company will show you its insurance without hesitation. Reluctance, or a vague promise to send it later, is a warning sign on its own.

Is there a duty of care for the crew?

This one matters more than people think. A company where staff routinely arrive at 9am and leave at 2am the next morning, with no support and no pastoral care, is not a well run business.

Tired crew make mistakes, and tired crew is a safety issue, not just a kindness issue. How a company looks after its people tells you how it will run your event.

The red flags, in short

If you want the quick version, walk away when you see:

• Mismatched or incompatible equipment brands
• No insurance, or reluctance to provide it
• Equipment that has not been PAT tested. PAT testing is the regular electrical safety testing that all professional companies carry out on their kit.
• No documentation: no kit list, no risk assessment, no method statement
• Everything driven by cost alone, rather than capability or safety

None of this is about spending the most money. It is about making sure the company you hire treats the job, and your show, with the seriousness it deserves. While you are at it, it helps to understand the difference between FOH and monitor engineers, so you know whether your show needs one engineer or two.

Frequently asked questions

What should I ask a live sound company before booking?

Ask whether they check access and power before quoting, whether they can give you a kit list in advance, whether their equipment brands are properly matched, and whether they provide CDM documentation, risk assessments, and insurance. A professional company answers all of these without hesitation.

What is a red flag when hiring a PA company?

Mismatched equipment brands, no insurance or reluctance to show it, equipment that has not been PAT tested, no kit list or risk assessment, and a company that only ever talks about price.

What is CDM in event production?

CDM stands for Construction Design and Management, the formal safety framework that governs how professional event production companies plan and manage risk.

Should a live sound company provide a kit list in advance?

Yes. A company that cannot tell you what it is bringing before the day is not properly organised.

People assume the big, famous events are the technically hard ones. Often the hardest job of the year is a community show, with a stage full of children, a cast that has never done a soundcheck, and no chance of a second take.

We genuinely love this work, and there is real skill in it. Here is what live sound for community shows actually involves, and why a scout gang show can be more demanding than it looks.

24 channels of radio microphones

Every year we supply the kit for a scout gang show that runs on 24 channels of radio microphones. That number alone tells you why these shows are a serious technical job.

Managing 24 radio mics at once is not just plugging things in. Each one needs its own clean radio frequency, and you have to coordinate all of them so that none of them interfere with each other. They have to be assigned, labelled, monitored, and mixed live, all while a fast-moving show is happening on stage. From the audience it looks effortless. Behind the desk, it is one of the more involved jobs you can take on.

That is exactly the kind of work where experience matters. A 24-channel radio mic show punishes anyone who has not planned the frequencies and the routing properly, and there is no pause button when it is live.

A stage full of children is its own challenge

Community shows often mean a large cast, and frequently a young one. That changes how you work.

Children do not hold a microphone like a touring vocalist, they move unpredictably, and they cannot be expected to manage their own audio. So the planning has to absorb all of that. You set levels that cope with a quiet voice one moment and a shout the next, and you build in the flexibility for things not to go quite to plan, because with a big young cast they sometimes will not. The job is to make every child heard clearly without anyone in the audience ever thinking about the sound.

Scale, when it is needed

These events can be large. We supplied a high-energy production for around 2,000 children at the Cheshire Scouts Chamboree, which runs every four years. That is a big crowd and a big atmosphere to fill, and it is a very different scale from an annual gang show, even though both are community events at heart.

Alongside those, we do community pantomimes, dance schools, and school events all the time. They are some of the most rewarding work we do, and we treat them with the same care we would give any other production.

Help for schools and community groups

We know budgets in this world are tight, so it is not only full production we offer. We also do PA and equipment hire, including academic pricing on wireless microphones.

That academic pricing exists for a specific reason. Schools often want to run their own shows but cannot afford to buy a large quantity of radio mics outright, so hiring them at a sensible rate makes a proper-sounding show possible. Whether you want us to run the whole thing or just supply the kit, there is usually a way to make a community show sound the way it deserves to.

Frequently asked questions

What does live sound for a community show involve?

Often a large number of radio microphones, a big cast that may include children, and a live performance with no second take. For one scout gang show we manage 24 channels of radio microphones.

Why are radio microphones tricky to manage at scale?

Every radio mic needs its own clean frequency, and running 24 at once means coordinating all of them so none interfere, then assigning, monitoring, and mixing them live.

Do you supply sound for large youth events?

Yes. We supplied a high-energy production for around 2,000 children at the Cheshire Scouts Chamboree, which runs every four years, as well as annual community shows, pantomimes, and school events.

Can schools and community groups hire equipment too?

Yes, including academic pricing on wireless microphones, because schools often cannot afford to buy a lot of radio mics outright.

Before founding PSL, I spent years as Technical Manager at the William Aston Hall in Wrexham. One night I was looking after sound for Martha Reeves, of Martha Reeves and the Vandellas.

The first time she played, I ran front of house and monitors myself from the one desk. No issues. The second time, the tour needed a separate monitor engineer, so I brought in a friend to cover the stage while I took front of house.

Soundcheck went on, and on. I was happy with the mix going out to the room, but the sound on stage was not right. The band were not comfortable. So I went up, asked the monitor engineer to step aside for a minute, and re-set the EQ across the whole stage rig. The band left the stage relatively happy.

After the show, Martha went to the monitor engineer first. She hugged him and thanked him for his hard work, which was a lovely thing to watch. Then she walked over to me, leant in, and whispered: “But don’t worry, I know that you’re the maestro.” A tap on the arm, and out she went.

Which had me dancing in the street. That is a Martha Reeves song. I am so sorry.

That night is the clearest example I can give of why these two jobs exist. The audience heard a great show. The band were quietly struggling. Same room, same gig, two completely different versions of the sound. That gap is the whole reason FOH and monitor engineering are separate disciplines.

What a front of house engineer actually does

The front of house engineer, or FOH engineer, is in charge of what the audience hears. That is the job in one sentence.

It goes deeper than pushing faders, though. A good FOH engineer is making decisions long before the show, like which microphone brands to use, where to place them on a drum kit, which polar patterns to choose, and how those mics capture the sound of the room itself. All of it feeds the one thing the audience experiences.

You are usually mixing with the artist’s management standing right next to you at the desk, which keeps you honest. You will never please everyone. Everyone in the room has a slightly different idea of what good sound is. So you mix for the majority and you make the show feel right.

The important thing to understand is that the artists on stage cannot hear your front of house mix. That can actually be a weight off their minds. What is going out to the crowd is your responsibility, not theirs. You are sending one main output to the audience, split left and right with subwoofers, and your whole focus is on making that single output as good as it can be.

What a monitor engineer actually does

The monitor engineer has a completely different job, and a very different stress profile.

Every musician on stage needs to hear themselves and each other, either through floor wedge speakers or through in-ear monitors. The monitor engineer builds a separate, dedicated mix for each one of them. Everyone on that stage is hearing something different, and all of it is being managed at once.

Here is what that means in practice. The bass player might want kick drum and snare clearly so they can lock in with the rhythm, plenty of their own bass so they can hear what they are playing, and probably less guitar and vocals. The singer might want their own vocal very prominent so they can pitch, a bit of the keyboard melody, and most other things turned down.

So the monitor engineer is not really mixing musically, the way a front of house engineer is. They are mixing to the personal preference of every individual on stage. On a bigger production that can be four mixes, or twelve, or twenty four, all running at the same time. Holding all of that together, live, at pace, with no chance to redo it, is the skill.

That is why the audience can be hearing a polished show while the band are having a hard night. If the monitors are off, the performers are fighting to hear themselves, and the front of house sound has nothing to do with it.

Why this matters when you book a live sound company

If you are a promoter, a band manager, or a venue booking a crew, the FOH versus monitor question is worth understanding before the day.

For a smaller show, one engineer running both from a single desk is completely normal and often the right call. It is how I ran Martha Reeves the first time, and how plenty of good gigs are run. The question is when your production has outgrown that.

The trigger is usually the number of individual mixes the stage needs. A solo act or a small band with simple monitoring is one thing. A larger act where six or eight people each need their own carefully balanced mix, especially with in-ear monitors, is another. At that point a dedicated monitor engineer stops being a luxury and becomes the thing that makes the show work.

A live event production company that knows what it is doing will tell you honestly which one your show needs, rather than selling you crew you do not require or sending one pair of hands to a job that needs two. If you want a fuller list of what to check before you book, we have written a guide on what to look for in a live sound company.

Frequently asked questions

What is the difference between FOH and monitor engineering?

The front of house engineer mixes what the audience hears. The monitor engineer mixes what the performers hear on stage, giving each musician their own individual mix through wedges or in-ear monitors. The audience never hears the monitor mix, but the band cannot perform well without it.

Does a small gig need both a FOH and a monitor engineer?

Not always. For a smaller show, one engineer can run both front of house and monitors from the same desk. As the production grows and more performers need their own individual mixes, a dedicated monitor engineer becomes worth it.

What does a monitor engineer actually do?

They build a separate mix for every person on stage, based on what each one needs to hear. A singer might want their own vocal loud, a bass player might want kick and snare to lock in with. Managing all of those mixes at once, live, is the job.

Why does the band sound fine to the audience but struggle on stage?

Because the audience hears the FOH mix and the band hears the monitor mix. If the monitors are not right, the performers can be struggling to hear themselves while the front of house sound is perfectly good. The two are completely separate.

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.
