Since its release, the PTAU-2 wireless microphone system has been widely appreciated for its powerful interference resistance, streamlined operation, and excellent sound quality. We heard from many users who expressed a need for a bodypack transmitter to enable hands-free operation.

To meet this demand, we developed the PWB-A2—a compact, lightweight bodypack transmitter. It helps users stay fully engaged and mobile while enjoying smooth, reliable wireless performance—ideal for live performances, presentations, fitness instruction, and other high-mobility scenarios.

Here’s a closer look at the key features of the PWB-A2 bodypack transmitter:

Stable Signal, Confident Performance

Built with the same true diversity architecture as the PTAU-2 system, this PWB-A2 UHF wireless bodypack transmitter delivers a stable, clear signal with up to 400ft line-of-sight range—even in challenging RF environments. Its advanced anti-interference design helps prevent dropouts, glitches, and distortion, letting users stay fully focused throughout their performance.

Selectable Phantom Power, Greater System Flexibility

To meet more specialized microphone needs, the PWB-A2 offers selectable 9V and 12V phantom power, expanding support for a wider range of condenser microphones. The 9V mode supports most lavalier and headset mics, while 12V accommodates higher-voltage models used for clear vocal capture and for instruments like violins—greatly enhancing system compatibility and versatility. Note: Phantom power (both 9V and 12V) is not suitable for dynamic or ribbon microphones.

Intuitive Controls, Smooth Operation

The PWB-A2 offers dedicated volume and mute buttons for quick adjustments, helping prevent unwanted feedback or background noise. A lock function can be enabled after setup to avoid accidental touches—ensuring smooth, secure operation on stage. A clear LCD screen displays real-time channel, frequency, and battery status, giving users full confidence and control throughout their performance.

Lightweight Design, Comfortable Fit

Designed for comfort and durability, the PWB-A2 features a lightweight body with a soft-touch, scratch-resistant finish. Its secure belt clip holds it firmly to clothing or a waistband, staying put even during vigorous movement—providing reliable performance for high-mobility scenarios like live shows, teaching, or fitness instruction.

Easy Pairing, Broad Connections

Designed for the PTAU-2 wireless microphone system, the PWB-A2 supports IR synchronisation that enables quick pairing with the receiver. Equipped with a standard 3-pin mini XLR jack, it works seamlessly with most lavalier and headset microphones on the market, allowing users to choose the ideal microphone for various scenarios.
