The Complete Guide to Audio Systems for Corporate Events
Audio is the backbone of communication at any event. It’s the invisible thread connecting presenters to audiences. Whether you’re hosting a breakout session or a general session for 500 guests, the clarity and consistency of your sound define how your event feels.
Here’s how to build a system that sounds professional and performs reliably, every time.
Start with the Room and Audience Size
Small rooms (under 100 people)
Use two powered speakers, a small mixer, and wireless handheld or lavalier mics for maximum flexibility.
Medium rooms (100–400 people)
Deploy distributed 12–15” speakers or compact line arrays. This prevents audio “hot spots” and uneven coverage.
Large sessions or ballrooms
Add subwoofers for low-end warmth and delay fills for rear coverage. AVR Expos engineers design systems that keep speech intelligible in large rooms.
Choosing Microphones
Wireless vs. wired
Wireless offers freedom and speed; wired is fail-proof. We stock Shure and Sennheiser systems with proper frequency coordination to avoid interference.
Lavalier, handheld, or headset
Lavs are great for presenters, handhelds for audience Q&A, and headsets for speakers who move dynamically.
Mixers and Signal Flow
Digital mixers
QSC TouchMix and Allen & Heath QU series mixers allow pre-saved EQ curves and fast recall. They’re compact, reliable, and optimized for corporate AV setups.
Playback and integration
We route laptops, video playback devices, and phones through DI boxes for clean, balanced signal flow into the system.
Redundancy and Power Management
Fail-safe design
We use labeled signal paths, redundant wireless receivers, and UPS backup systems to ensure stability.
On-site support
Every major event includes a dedicated AVR Expos technician to monitor audio quality throughout.
