TrueWave Pro AIR-B4 Quad-Channel UHF Wireless Microphone System

Professional 4-Channel Wireless Microphone System for Events, Worship & Professional Audio

Take your live audio setup to the next level with the TrueWave Pro AIR-B4 Quad-Channel UHF Wireless Microphone System — a professional wireless microphone solution designed for events, houses of worship, conferences, schools, venues, presentations and live productions.

With four independent UHF wireless microphone channels, True Diversity reception, rechargeable handheld microphones, Auto Scan frequency selection and IR synchronisation, the AIR-B4 gives you the flexibility and reliability you need when multiple speakers or performers need to be heard clearly.

The system combines professional features with simple setup, making it an excellent choice for both permanent installations and mobile event production.

🎤 Four Wireless Microphones. One Professional System.

The AIR-B4 includes four rechargeable handheld wireless microphones, allowing up to four microphones to operate simultaneously through a single 1U rackmount receiver.

Whether you're running a church service, panel discussion, conference, school event, corporate presentation or live performance, four independent channels give you the flexibility to manage multiple presenters or performers without needing multiple receivers.

📡 True Diversity UHF Reception

Wireless reliability matters when you're on stage.

The AIR-B4 uses True Diversity UHF reception to help maintain a stable wireless connection and minimise the risk of unwanted signal interruptions. With an operating range of up to 100 metres line-of-sight, the system provides plenty of freedom for presenters and performers to move around the venue.

⚡ Fast & Easy Setup

Setting up multiple wireless microphones shouldn't be complicated.

The AIR-B4 features Auto Scan to help find a suitable operating frequency, while IR synchronisation makes pairing each microphone with the receiver quick and straightforward.

Simply scan, sync and start using your microphones.

🔋 Rechargeable Wireless Microphones

Forget constantly replacing disposable batteries.

Each AIR-B4 handheld microphone uses a removable 18650 rechargeable lithium battery and provides approximately 10 hours of battery life per charge.

Magnetic charging cables are included, making it easy to keep all four microphones ready for your next event.

🎚️ Professional Audio Connections

The 1U rackmount receiver provides four individual balanced XLR outputs, giving you independent control of each microphone through your mixer, digital console, amplifier or PA system.

A 6.35 mm mixed output is also provided when you want to combine the four microphone channels into a single output.

This makes the AIR-B4 suitable for everything from compact PA systems to professional installed audio systems.

🏢 Built for Professional Installations

The AIR-B4's 1U rackmount receiver is designed to integrate neatly into standard 19-inch equipment racks.

It is an ideal wireless microphone solution for:

• Houses of worship and churches

• Conference rooms and meeting spaces

• Corporate presentations

• Schools and universities

• Community halls
