If you’re wondering how to build a PA system that delivers reliable, clear audio for your space, you’ve come to the right place.
Building a PA system involves establishing needs, choosing the right gear, choosing between wired and wireless options, and establishing if an installer is needed.
Whether you’re setting up for a school, business, church, or event venue, getting the fundamentals right is key to lasting performance.
Our expert PA system installers have prepared this beginner’s guide to help you understand the ins and outs.
Quick Summary
- Start with your needs: Audience size, space type, and usage.
- Use the right gear: Microphones, speakers, amplifiers, mixers, cabling.
- Choose between wired or wireless systems.
- Smart IP-based systems offer added features like remote access and emergency alerts.
- Professional installation ensures optimal setup and support.
1. Pick Your Components
Building a PA system requires the following core components:
Microphones
- Wired mics: Reliable, ideal for fixed setups.
- Wireless mics: Flexible and portable.
- Lapel/headset mics: Perfect for presentations or teaching.
Mixers & Amplifiers
- Mixers let you control volume levels, inputs, and sound quality.
- Amplifiers boost the signal for effective sound distribution.
Speakers
- Wall-mounted, ceiling-mounted or portable options.
- Active (built-in amplifier) or passive (requires external amp).
Control Panels
Touch panels or desktop interfaces to control audio zones, volume, and source.
Cabling or IP Networking
- Traditional wired setups use speaker and mic cables.
- Modern IP-based systems run over your network with Power over Ethernet (PoE).
Emergency Duress Features (Optional)
Smart systems can include built-in duress buttons, emergency override, and remote access.
3. Wired vs Wireless PA Systems
| Feature | Wired Systems | Wireless Systems |
|---|---|---|
| Reliability | Highly reliable, stable connection | Subject to interference or dropouts |
| Installation | Takes longer, more infrastructure | Faster to install, easier to relocate |
| Scalability | Better for fixed setups | Great for flexible/multi-zone use |
| Cost | Lower long-term costs | Higher initial investment |
Choose wired if reliability is your priority. Go wireless if flexibility and remote control are more important.
4. Planning Your Setup
- Map the coverage area (rooms, outdoor zones, etc.)
- Identify control locations (reception desk, office, AV room)
- Decide on fixed vs portable equipment
- Choose your preferred brand (e.g. AXIS or AXIOM for IP-based systems)
5. Step-by-Step: How to Build Your Own PA System
- Choose your components based on environment and goals
- Mount speakers in appropriate locations (ceiling, wall, pole, etc.)
- Connect microphones to the mixer
- Run signal to amplifier, then to speakers (or connect IP speakers over network)
- Install control panel in easy-access area
- Power on system and configure zones/volume levels
- Test the system for sound clarity and coverage
- Train users on how to operate the system
