The success of an exhibition often hinges on how clearly your message is heard. Whether you are announcing live demos, sharing product details, or simply playing background music, having a reliable PA system can make or break your stand’s success
But here is the deal: not everyone has a sound engineer on speed dial. And honestly, you don’t need to be a tech wizard to run a basic PA system at your exhibition. With a little know-how and preparation, you can set up and operate it like a pro.
10 TIPS TO USE A BASIC PA SYSTEM
In this guide, we will break down everything one needs to know from choosing the right tools to playing it well. Moreover, even how to avoid feedback disasters. So let’s plug in your mic and get started.
WHY A PA SYSTEM MATTERS AT AN EXHIBITION
Before we get technical, let’s talk about why you need a PA system in the first place. Exhibitions are noisy. You have got people chatting, machines humming, and competitors doing their best to outshine you. A PA system helps:
- Amplify your voice so you don’t have to shout.
- Play background music to set the tone.
- Announce promotions or activities that pull visitors in.
- Add a professional touch to your stand.
Think of it as your audio sidekick, one that makes sure your message cuts through the clutter.
KNOW YOUR SYSTEM COMPONENTS
Let’s start with the basics, understanding the functions and features of the components. Usually, a basic PA system used for exhibitions includes the following:
- Microphone: For speaking or presenting.
- Mixer or amplifier: This controls the volume and audio input.
- Speakers: to project the sound outward.
- Cables and connectors to hook everything together.
- Optional extras: Bluetooth input, media players, or wireless mics.
You don’t need to go overboard; a simple setup with a mic, mixer, amplifier, and two speakers is usually enough. Especially if your stand is of the medium to small size, it will be all you may need.
TIP 1: CHOOSE THE RIGHT PA SYSTEM FOR YOUR SPACE
Not all exhibition booths are created equal. Some are open while others are enclosed or shared with neighbours. Here is how to match your PA to your space:
| BOOTH SIZE | SIZE | PA SYSTEM |
| Small Booth | 2x2m to 3x3m | A compact one portable PA system with built-in speakers and a microphone will do the job. |
| Medium Booth | up to 6×6 m | A system with external speakers and a separate mixer/amp. |
| Large Booth | Higher than 6×6 m | Get a more powerful system with multiple speakers placed strategically around your stand. |
Pro tip: always check your venue’s sound rules and regulations too, as some of them have decibel limits.
TIP 2: KEEP IT SIMPLE, DON’T OVERCOMPLICATE THE SETUP
Don’t overcomplicate your setup. When you’re juggling a dozen other exhibition tasks, the last thing you want is to fumble with tangled cables and blinking lights. So simplicity is the key here to achieve your goal. Before you start, here is what to keep in mind:
- Use colour-coded cables or label them for quick setup and teardown.
Stick with one or two microphones, a handheld, and a wireless lapel mic is usually enough.
- If you are playing music, a Bluetooth-enabled speaker system can save you a lot of hassle.
TIP 3: TEST IT BEFORE SHOW DAY
Would you try a new recipe for the first time during a dinner party? Probably not. The same goes for your PA system. Test it before the exhibition, ideally in a space similar to your booth space. So check the following:
- Sound Clarity: Walk around to make sure the sound covers the area.
- Feedback: Watch for that annoying squeal more on this below.
- Volume Levels: Make sure you are not blowing out your eardrums or going too quiet.
Moreover, do a dry run of your presentation or announcements with your mic to see how it sounds in real time.
TIP 4: MASTER THE MICROPHONE BASICS
Holding a microphone properly is half of the battle. Here is a crash course in mic etiquette for you in a few lines, check this out:
- Hold it 2-3 inches from your mouth.
- Speak clearly and confidently, don’t mumble or shout.
- Avoid moving it around too much, and it can create static or popping sounds.
- Use a mic stand if you are presenting hands-free.
And remember to mute your mic when not speaking. No one would like to hear your sneeze or random side chat.
TIP 5: BEAT THE FEEDBACK MONSTER
Feedback is that high-pitched scream that happens when the mic picks up sound from the speaker and loops it endlessly. It’s uncomfortable and unprofessional.
Here is how to avoid it:
- Keep the mic pointed away from the speakers.
- Don’t stand directly in front of the speakers while talking.
- Lower the volume slightly if feedback occurs.
- Use a unidirectional microphone that only picks up sound from one direction.
If all else fails, get someone to help you adjust levels while you test the mic live.
TIP 6: BALANCE YOUR SOUND LEVELS
A good PA system is not just about volume; it is about balance. You want your voice or music to be loud enough to hear, but not so loud that it scares people away. Here’s a quick checklist to help you strike the perfect balance:
- Keep background music at an ambient level so it doesn’t overpower conversations.
- Use the “gain” knob on your mixer to fine tune the input level from your mic.
- Adjust the EQ settings(bass, mid, treble) to make your voice sound warmer or clearer.
Suppose you’re playing music and speaking over it. Lower the music over it, lower the music volume while talking.
CONFIDENCE+ CLARITY= IMPACT
A good PA system helps you command attention, deliver your message clearly, and create a lively atmosphere. All of which are crucial at an exhibition.
And guess what? You don’t need a fancy rig or a sound tech team to make it work. With a bit of planning, practice, and the right mindset, you can run your own PA system smoothly and stress-free.
So go ahead, step up to the mic, turn up the volume, and let your brand’s voice shine.
