Engineered for Wind Instruments 
Engineered specifically for saxophones, trumpets, and other brass/woodwind instruments, this system tackles the unique challenges wind players face. Its precision clamping system contours perfectly to the instrument’s bell or mouthpiece, ensuring a secure, non-invasive fit that doesn’t interfere with your performance. This thoughtful innovation solves the long-standing challenge of unreliable mic placement during live shows, delivering clean, consistent audio capture, so your sound is as expressive as your playing, maintaining full artistic freedom.

Effortless Setup with Auto Pairing & Frequency Hopping
The NUX B-6 PRO takes the hassle out of setup with its automatic pairing, just power on the transmitter and receiver, and they'll sync in seconds. It also features intelligent frequency hopping technology, which automatically scans and switches to the most stable signal. This ensures seamless, interference-free wireless transmission, even in crowded performance environments.

Extended Range, Ultra-Low Latency for Pro-Level Performance 
Equipped with next-generation wireless transmission technology, the NUX B-6 PRO is designed to deliver exceptional signal stability and responsiveness. With a maximum range of up to 165 feet and latency as low as 3.6ms, it ensures that your performance stays in perfect sync, whether you're on a large stage or moving through a dynamic venue.

The system allows you to optimize transmission settings in real-time, choosing between Low Latency Mode for ultra-fast response or Stable Mode for enhanced signal reliability in challenging environments. This balance of speed and stability makes the B-6PRO ideal for both live shows and professional studio sessions.

Patented Shock-Absorbing Gooseneck Microphone Design 
The NUX B-6 PRO introduces a newly engineered shock absorption system, specially designed to minimize unwanted resonance and handling noise during live performance. This patented gooseneck structure effectively isolates the microphone from mechanical vibrations and button clicks, ensuring that what your audience hears is only your playing, not the distractions. At it's core is a custom unidirectional electret condenser microphone, delivering clear, detailed, and focused sound capture tailored specifically for wind instruments.

Quick Installation with a Secure, Instrument-Friendly Clamp Design

Engineered for fast, hassle-free setup, the clamp includes a flexible, rubber-coated contact grip that securely attaches to the bell of saxophones, trumpets and other brass or woodwind instruments. This thoughtful design ensures stability during movement while protecting your instrument’s finish, giving you reliable performance without compromise.

Gentle, Non-Slip Contact 
The soft rubber-coated contact points prevent direct metal-to-metal friction, eliminating scratches and wear while enhancing both safety and stability.
