A practical guide to PA system selection for events of different sizes, types and environments, written for operators who will be running the rig themselves.
PA system dry hirePA selection begins with the room, not the programme. Before you can decide what kind of system you need, you need to understand the space you are putting it in. Two questions determine the starting point:
How large is the audience area, and what shape is it? A long narrow room, a wide shallow room and a square room with equal throw distances in all directions need different coverage solutions. Know your room dimensions and where the audience is positioned relative to the stage.
What are the acoustic properties? Hard-walled rooms with low ceilings create reflections that fight PA coverage. Tented events with fabric surfaces behave differently again. An outdoor site with no boundaries at all has no reverb but far-throw requirements. The right system for each is different — sometimes substantially so.
| System Type | Best For | Considerations |
|---|---|---|
| Line Array | Larger audiences (300+), long throw requirements, outdoor events, concerts, festivals | Requires rigging or ground-stacking, heavier to transport, more complex to tune, needs experienced operator |
| Point Source | Smaller venues, corporate events, dinners, presentations, rooms up to ~300 people | Simpler to deploy, lighter, easier to position accurately, generally easier to tune for speech |
| Column Array | Speech-heavy events in reverberant rooms, churches, banqueting halls | Excellent directional control for speech, less suited to music-heavy programmes |
For most dry hire PA bookings at events between 100 and 500 people, a quality point-source system with appropriate sub support is the practical choice. Line array moves to the front when throw distance, audience depth or programme type demands it.
Subwoofers. For speech-only events, sub provision is minimal. The moment your programme includes music, DJ sets, live bands or playback with significant low-frequency content, sub support becomes important. A PA that sounds thin without subs in a music-heavy programme will underdeliver regardless of how clean the tops are. Discuss your programme type when booking to get the sub configuration right.
Stage monitoring. Performers need to hear themselves. Wedge monitors on stage are a separate part of the PA system from the FOH hangs and need their own amplification and console aux sends. Confirm the number of monitor mixes your programme requires. For solo performers or small acoustic sets, two or three mixes is typical. For full bands or large productions it can be significantly more, and in-ear monitoring systems can add further specification complexity.
Book the console your operator knows, not the most impressive option in the catalogue. A Yamaha CL5, a DiGiCo SD9 and an Allen and Heath dLive all produce excellent results in the hands of a qualified operator. They are very different to use, and on event day with 45 minutes left before doors, discovering a workflow you are not fluent in is a problem you do not need.
The console specification also needs to match the input count. Check:
A typical event PA system draws significantly more power than most people estimate before they do the calculation. Active loudspeakers with integrated amplification have their draw published in the spec sheet. Passive systems fed by separate amplifiers depend on the amp spec. Add these up before assuming the venue can supply what you need.
Rules of thumb for planning conversations with venue technical managers:
Your hire company can provide specific draw figures for every item on your kit list. Use them. Do not estimate.
