B-11 PRO
Where Technology Meets Elegance
The NUX B-11 PRO Wireless System is a perfect fusion of advanced technology and refined elegance, designed specifically for violin and viola.
It frees you completely from the limitations of traditional wired pickups. Powered by NUX’s advanced wireless technology, it delivers professional-grade 24-bit / 48 kHz high-quality audio transmission.
With an ultra-low latency of just 3.6 ms and a transmission range of up to 165 feet, you gain complete freedom of movement on stage—letting the music flow effortlessly.
Automatic Pairing + Intelligent Frequency Hopping
Simply power on the transmitter and receiver, and they will automatically pair within seconds.
During operation, the system continuously scans the surrounding wireless environment. When interference is detected, it instantly switches to a cleaner channel, ensuring a stable connection and clear, uninterrupted audio.
Longer Range, Lower Latency
Powered by NUX’s advanced 2.4 GHz wireless technology, the system delivers outstanding transmission performance and sound quality.
During use, the transmission mode can be adjusted between Low Latency and Stable according to the surrounding environment.
Latency can be as low as 3.6 ms, with a transmission range of up to 50 meters (165 feet).
Upgraded Microphone Assembly
Equipped with a cardioid condenser instrument microphone, capturing a natural, full-bodied tone rich in detail.
A newly designed shock-absorbing structure significantly reduces vibration while further minimizing the size and weight of the microphone assembly—greatly enhancing the overall playing experience.
Quick Installation, Stable and Reliable
Designed specifically for violin and viola, the transmitter features a magnetic design that allows quick attachment to the transmitter mount during performance breaks, or easy removal for charging. (The transmitter mount is fixed to the edge of the instrument body.)
High-Capacity Lithium Battery + Magnetic Charging
Both the transmitter and receiver are equipped with high-capacity lithium batteries. A fully charged transmitter provides up to 6.5 hours of operation.
During breaks, the transmitter can be conveniently placed on top of the receiver for charging.
Built-in Reverb Effect
Features a professional-grade built-in reverb effect, activated with a single press of the button on the right side of the transmitter.
Detailed reverb parameters can be adjusted through the receiver’s UI menu.
