The Complete Guide to Audio Systems for Corporate Events

Communication within any destination is reliant on audio. It is the unseen rope between the presenters and the audiences. Whether you are setting up a break out session or a general session to accommodate 500 guests, the distinctiveness and harmony of your sound determine how your event will be experienced.

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.
