Truly great festival sound has to do a lot more than simply be loud.
Outdoors, there are no walls or ceilings helping to contain the sound. Wind, site layout, crowd size and even the shape of the ground can all affect what people hear. A system that works perfectly well inside a venue may feel underpowered or uneven when it is moved into an open field.
That makes choosing the right PA system a very important part of festival planning.
Whether you are organising a small community event or a large multi-stage festival, the aim is the same: clear, consistent sound across the audience area without creating unnecessary volume or causing problems elsewhere on site.
Here are the main things to consider when arranging outdoor PA system hire for your event.
Start With the Size and Layout of the Festival Site
Audience numbers matter, but they only tell part of the story.
Two festivals expecting 2,000 people could require completely different sound systems depending on how the site is laid out. A long, narrow audience area creates different challenges to a wide festival field, while sloping ground, nearby structures and separate stages can all influence the design.
Before specifying any equipment, it helps to understand:
- The expected audience capacity
- The distance from the stage to the rear of the crowd
- The width and shape of the audience area
- Whether there are multiple stages or performance areas
- Nearby residential areas or noise-sensitive locations
- Where front of house, PA towers and other infrastructure can safely sit
For larger festival sites, one set of speakers at the front of the stage is rarely enough.
Additional fills or delay speakers can be positioned further into the site to maintain clarity without simply pushing the main PA louder. Done properly, this gives audiences at the rear a much better experience while allowing the overall system to operate more efficiently. If you’re unsure on the best systems for your environment, get in touch with the team and we can help you understand exactly what will be needed.
Think About Coverage, Rather Than Just Volume
One of the most common mistakes when choosing a festival PA is focusing almost entirely on power.
More volume does not automatically mean better sound.
A professional PA system should distribute sound evenly across the audience area, so somebody standing near the mix position receives a similar experience to somebody further back. This is where line array systems are often favoured for larger outdoor events.
Rather than relying on a small number of speakers firing sound across a large area, line arrays allow engineers to control how audio is distributed vertically and horizontally. The system can then be configured around the shape of the crowd and the distances involved.
At TruCru, our festival audio systems include professional Martin Audio PA systems, including line arrays, front fills and delay solutions that can be scaled around the requirements of each site.
The right configuration will depend on the festival rather than simply choosing the biggest system available.
Consider What Is Actually Happening on Stage
A spoken-word festival has very different audio requirements to a live music event.
Even within music festivals, the type of performance makes a difference.
A DJ stage may require substantial low-frequency output and a comparatively straightforward input setup.
It is therefore worth looking at your running order before finalising the PA.
Questions such as how many performers are appearing, what instruments they are bringing and whether touring artists have technical riders can have a major impact on the equipment required.
The PA is only one part of that picture. Mixing consoles, stage boxes, microphones, monitors, radio systems and audio playback all need to work together.
Getting this information early makes the technical planning far smoother when the festival arrives.
Outdoor Conditions Need to Be Taken Seriously
British festival weather rarely sticks to the programme.
Even during summer, an outdoor system may have to deal with strong winds, rain and rapidly changing conditions.
Wind is particularly important when it comes to sound. Because audio is travelling through open air, changing wind direction can alter how consistently sound reaches different parts of a festival site.
Rain creates another consideration, particularly around electrical equipment, connections and control positions.
Professional outdoor festival production therefore needs to consider much more than the specification of the speakers themselves. Equipment placement, structures, cable routes, power distribution and weather protection all form part of the wider setup.
It is one reason why outdoor PA system hire often benefits from having experienced festival technicians involved rather than treating the system as a simple equipment rental.
Don’t Forget the Front of House Position
The front of house position is where your audio engineer mixes what the audience hears.
Its location matters.
If the engineer is tucked behind a structure, positioned too far to one side or unable to hear the same sound as the majority of the audience, accurately mixing the event becomes much harder.
Ideally, front of house should sit somewhere representative of the main listening area.
The FOH position may also house lighting, video and other production control, so its footprint and cable routes should be included in the site plan from the beginning.
Outdoor PA System Hire From TruCru
Festival production is a major part of what we do at TruCru.
From smaller outdoor events through to nationally recognised festivals, our team provides professional PA systems, mixing consoles, wireless systems and experienced audio crew for events across the UK.
Our audio inventory includes equipment from trusted live production brands including Martin Audio, Allen & Heath and Sennheiser, with systems available for anything from a single performance area through to complex multi-stage festivals.
We can provide standalone outdoor PA system hire, assisted equipment hire or complete festival production incorporating staging, lighting, video, rigging and technical crew.
Most importantly, the system is planned around your event.
If you are organising an outdoor festival and are unsure what PA equipment you need, speak to the TruCru team. We can review your site, audience numbers and production requirements before recommending a system that gives your audience clear, consistent sound from the first act to the final encore.
