The right PA system depends on audience size, venue acoustics, event type, and whether the event is indoors or outdoors. Small events up to 80 guests start from £150, medium events from £400, and large events from £1,200. Always check for noise limiters before confirming any indoor venue setup. Outdoor events need significantly more power than indoor equivalents. Active speakers suit most hire setups. A sound engineer is recommended for any event above 100 guests or with multiple microphones.

This is one of the most important decisions you will make when organising any event. Get it right and the room sounds effortless. Get it wrong and guests strain to hear, sound cuts out during speeches, or the music feels flat and thin.
The right choice depends on your audience size, venue type, event format, and whether you need a technician to manage the system on the day. This guide explains what actually affects PA system choice, what realistic UK hire costs look like, and what to look for before booking.
Written by Jack Bridges, Founder of Beatz Hire and Event Production Specialist, supporting events across London and the South East.
At Beatz Hire, we supply PA systems, speakers, subwoofers, digital mixers, and wireless microphones for events across London, Surrey, Berkshire, Hampshire, Oxfordshire, and Buckinghamshire. We stock RCF and L-Acoustics systems alongside Allen and Heath digital mixers. This guide is based on real experience delivering sound for corporate events, conferences, festivals, weddings, and private functions across the South East.
A PA system, short for public address system, is the combination of speakers, subwoofers, a mixer, microphones, and cabling that captures, processes, and amplifies sound so an audience can hear clearly.
At its simplest, a PA system takes a voice or music source, runs it through a mixer where levels and tone are adjusted, and pushes the signal out through speakers. The size, power, and configuration of the system changes significantly depending on how many people need to hear it, how far away they are, and what kind of audio is being produced.
Speech and music have different requirements. A conference with one presenter needs clarity and even coverage above all else. A live band or DJ set needs low-end power, wider frequency range, and significantly more output. Choosing a system built for the wrong application is one of the most common reasons events have poor sound.
The number of guests is the starting point for any PA system decision, but it is not the only factor. Room shape, ceiling height, acoustic treatment, and whether the event is indoors or outdoors all affect what the system needs to do.
A compact dry room with 80 guests may need less system than a high-ceilinged hotel ballroom with the same number of people. Hard floors, glass walls, and reflective surfaces create echo and delay that a larger, more carefully placed system needs to manage.
The event type matters too. A corporate dinner with background music and a couple of speeches needs a completely different setup from a DJ night, an awards ceremony, or a conference with five panellists all needing live microphones.
Typical hire cost: from £150 to £400 per day
Small events including private parties, birthday celebrations, engagement parties, small corporate meetings, and intimate weddings generally need a compact active speaker setup.
Two active speakers on stands, a basic mixer, and one or two wireless microphones is the standard starting point. At this scale, subwoofers are not usually necessary for speech-led events, though they add quality to music-led ones.
A typical small event PA setup from Beatz Hire includes:
This setup handles clear speech coverage across most rooms up to around 80 guests without overpowering the space.
Typical hire cost: from £400 to £1,200 per day
Medium events including corporate dinners, weddings, awards ceremonies, product launches, and Christmas parties need a more capable system that can handle both speech and music without compromising either.
At this scale, subwoofers become important for music-led events. Without them, bass frequencies disappear and music feels thin. Multiple wireless microphone channels are needed for events with panel discussions, Q&A sessions, or multiple speakers.
A typical medium event PA setup from Beatz Hire includes:
Speaker placement becomes more important at this scale. Two speakers in the wrong position leave parts of the room with poor coverage. An experienced crew positions the system correctly before doors open.
Typical hire cost: from £1,200 to £3,500 per day
Large events including conferences, festivals, outdoor events, large corporate productions, and public shows require professional-grade systems designed to cover significant distances with consistent quality.
At this level, line array systems deliver even sound across the full audience area without excessive volume at the front. L-Acoustics and RCF HDL systems are the standard at this scale. Multiple subwoofer stacks handle low-end frequencies. A front-of-house engineer manages levels, microphone handovers, and any issues throughout the event.
A typical large event PA setup from Beatz Hire includes:
At this scale, a technician is not optional. Managing a large PA system in real time, handling microphone changeovers, and preventing feedback during a live event requires experience and constant attention.
Outdoor events present a fundamentally different challenge from indoor ones. Sound has no walls to reflect off, which means it disperses quickly in open air. A system that sounds loud and clear indoors can feel thin and distant at the same outdoor volume level.
Outdoor PA systems typically need significantly more output to achieve the same perceived volume as an indoor system. Subwoofers are particularly important outdoors because low-end frequencies disappear fastest in open air.
Speaker positioning matters more outdoors because there is no room to help distribute sound. Delay speakers or additional satellite speakers may be needed for longer sites where the main PA cannot reach evenly.
Power distribution is also a consideration. Many outdoor sites do not have convenient mains supply near the stage area, which means 16A power runs or generator hire may be required alongside the PA system.
Outdoor PA hire typically costs 20 to 40 percent more than an equivalent indoor setup due to the larger system requirements and additional logistics.
Noise limiters.
Many UK venues, particularly hotels, function rooms, and converted spaces, have automatic noise limiting systems installed. These cut power to the PA or reduce output if the volume goes above a set decibel level. They are often positioned near the stage where bass frequencies peak, which means they trigger frequently during music-led events.
We have been on events where a DJ's setup has triggered the noise limiter repeatedly during the first hour, disrupting the event and requiring a complete system change. This is entirely avoidable if the noise limiter is identified and accounted for before booking the system.
Before confirming a PA system for any indoor venue, always confirm:
This is one of the most important pre-event checks and one of the most frequently skipped.
The microphone choice is as important as the speakers. Different event formats need different microphone types.
Wireless lapel microphones suit keynote speakers and conference presenters who need hands-free delivery. They clip to clothing and pick up speech clearly without the presenter needing to hold anything.
Wireless handheld microphones suit comperes, awards presenters, and Q&A sessions. They are easy to pass between people and straightforward for guests to use without instruction.
Top-table or boundary microphones suit panel discussions where multiple people are seated at a table. A single boundary microphone picks up everyone within range without requiring each panellist to hold one.
Headset microphones suit performers and presenters who need total hands-free freedom of movement.
Getting the microphone choice wrong creates problems that even an excellent speaker system cannot fix. A lapel microphone worn in the wrong position creates handling noise and inconsistent pickup. A handheld microphone not held close enough to the mouth produces thin, distant audio.
Most hire setups use active speakers, which have built-in amplifiers. They are easier to set up, require fewer components, and work well for most event sizes.
Passive speakers require separate amplifiers and are more common at larger professional setups where engineers want greater control over amplifier levels and speaker distribution. They allow finer tuning of individual speaker zones across a complex venue.
For events up to around 200 guests, active systems are almost always the right choice. For larger productions with complex audio requirements, passive systems with separate amplification give the production team more control.
Six factors drive the final price of any PA system hire.
System size and specification. Larger systems with more speakers, subwoofers, and advanced mixers cost more. RCF and L-Acoustics systems are priced higher than entry-level alternatives because they deliver measurably better performance.
Indoor vs outdoor. Outdoor events require larger systems and additional logistics, increasing overall cost.
Hire duration. Day hire rates apply to single-day events. Multi-day events often attract lower per-day rates.
Delivery, setup, and collection. Some suppliers quote equipment only. Others include delivery and setup. Always confirm what is included before comparing prices.
Technician support. A technician managing the system throughout the event adds cost but reduces risk significantly. For events above 100 guests or any event with multiple microphones, this is worth including.
Additional equipment. Staging, lighting, DJ equipment, and screens all add to the total but booking through one supplier usually reduces overall cost and removes coordination problems on the day.
Some clients need individual items rather than a full package. Realistic day hire rates for common PA components:
Pricing depends on hire duration, delivery location, and whether setup support is included.
For events up to around 80 guests with a straightforward setup, a basic system can often be managed without a dedicated engineer if someone on site understands the equipment.
For anything larger, or any event with multiple microphones, live performers, speeches alongside music, or complex changeovers, a sound engineer is worth the cost. They manage levels in real time, prevent feedback, handle microphone handovers cleanly, and solve problems before they become audible to guests.
Sound engineer day rates typically range from £200 to £450 depending on event length and complexity.
Choosing a system based on price alone. A cheaper PA system in the wrong room sounds worse than a correctly specified mid-range system. Match the specification to the event, not the budget.
Ignoring room acoustics. Hard floors, glass walls, and high ceilings create echo. A system that sounds great in a dry room can sound chaotic in a reflective space without proper EQ and speaker positioning.
Skipping the sound check. Every room sounds different when it fills with people. A sound check in an empty room sets a starting point. An engineer then adjusts throughout the event as the room changes.
Poor speaker placement. Two speakers pointed straight ahead in a wide room leave the sides with poor coverage. Angling and positioning speakers correctly is as important as the speakers themselves.
Not checking for noise limiters. Covered in detail above. Always check before confirming any system for an indoor venue.
Assuming the venue has what you need. Many hotel and venue house systems are adequate for background music and basic presentations. They are not always suitable for DJ sets, live bands, or conferences with multiple wireless microphone channels. Always check before assuming.
For 100 guests in a typical indoor venue, two to four active speakers with at least one subwoofer, a digital mixer, and two to three wireless microphone channels is a sensible starting point. The exact system depends on whether the event is speech-led or music-led and the acoustics of the room.
Not always. For speech-only events in a small to medium room, subwoofers are not essential. They become more important when music is involved or when the event is outdoors where low-end frequencies dissipate quickly.
Active speakers have built-in amplifiers and are easier to set up. Passive speakers require separate amplifiers and offer greater control for larger, more complex setups. Most hire events use active systems.
The same equipment can technically be used in both environments, but outdoor events typically need more output to achieve the same coverage. A system sized for an indoor event will often feel underpowered outdoors.
For events above 100 guests, or any event with multiple microphones, live performers, or complex audio requirements, a sound engineer is strongly recommended. For smaller simple setups, it may not be necessary.
For summer events and December, three to six months is sensible. For other times of year, four to six weeks is usually sufficient for standard setups. Urgent bookings are possible where stock allows.
