The B-8S Guitar Wireless System is a professional-grade solution in NUX’s PRO Series. Built on our third-generation platform, it combines anti-interference tech, intelligent frequency hopping, 1MHz narrowband transmission, Audio Zip/Unzip, six stability levels, and a true-diversity dual-antenna design for rock-solid, reliable signal. The latest firmware further improves wireless performance with better transmission efficiency and stronger interference resistance.
Designed for guitars, basses, and any instrument with a 1/4″ output, the system pairs a beltpack transmitter with a multifunction pedal receiver. It operates at 2.4 GHz, supports auto-pairing, delivers 24-bit / 48 kHz audio, achieves latency down to 2.5 ms, and reaches up to 165 ft (50 m) line-of-sight. The transmitter’s built-in lithium battery provides up to 6.5 hours of runtime! Enough for rehearsals, sessions, and gigs.
Intelligent Frequency Hopping
While in use, the B-8S automatically scans the 2.4 GHz band and switches to the cleaner channel when interference is detected, ensuring a stable connection and clear audio throughout your performance.
1 MHz Narrowband Transmission for Improved Spectrum Efficiency
The B-8S system reduces the channel bandwidth from 2 MHz to 1 MHz, significantly improving utilization of the 2.4 GHz frequency band and increasing the number of available channels to up to 79. This gives the intelligent frequency-hopping technology more channel options to effectively avoid interference from Wi-Fi and other wireless devices. Even in environments with a high density of wireless equipment, the B-8S delivers stable and reliable signal transmission.
For bands with multiple guitarists, up to 10 B-8S systems can be used simultaneously while maintaining optimal wireless performance and signal stability.
6-Level Stability and Audio Zip/Unzip
The B-8S offers six stability levels, with latency ranging from 2.5 ms to 8.7 ms. Higher stability levels increase the number of signal transmissions, with up to 12 transmissions occurring within 8.7 ms. Since interference varies over time, more frequent transmissions can help reduce interference-related issues.
The B-8S uses Audio Zip/Unzip technology to deliver 24-bit / 48 kHz audio quality, ensuring clear and stable sound in combination with its six-level stability settings.
The 1 MHz Zip technology enhances anti-interference performance. It works like a motorcycle using a narrow 1 MHz lane to navigate smoothly through traffic on a crowded 2.4–2.483 GHz highway, compared with a wider 4 MHz truck.
Beltpack Transmitter
The compact beltpack clips easily onto a strap or pocket. Its jack design prevents rotation and loosening, keeping the plug securely in place even during energetic movement.
The B-8S is compatible with electric guitars, electro-acoustic guitars, basses, and other instruments equipped with pickups.
Cable Tone
The TX features a cable tone simulation which is normally used by some guitar players to get a warmer sound. If you want it, you can flip the switch and turn it on.
A Multifunction Pedal Receiver
The B-8S combines multiple practical features into a single unit, including wireless transmission, a tuner, a junction box, boost and buffer functions, DI functionality, a guitar input, and a magnetic charging port for the transmitter.
This all-in-one design simplifies stage setup and signal management, improving workflow and enhancing live performance efficiency.
A 2.4-Inch Color Display with Horizontal and Vertical display
The receiver features a 2.4-inch color screen that displays the battery level, input volume, and settings in real time, making monitoring and adjustments quick and easy while improving on-stage efficiency. The screen supports both Horizontal and Vertical display modes to accommodate different usage needs.
And On-Board Tuner
The included tuner features NUX’s high-sensitivity tuning technology for accurate and smooth tuning. Four tuning modes are available: Chromatic, Guitar Standard, Guitar Compensated, and Bass. The A4 reference frequency is adjustable from 430 Hz to 450 Hz, with customizable tuner animations.
A 12 dB Clean Boost
Increase your guitar volume and dynamics with 0 to +12 dB boost for a fuller sound. Ideal for soloing, enhancing an overdrive, and maintaining consistent output during pickup changes. This ensures a clear and powerful performance.
Magnetic Charging Port
The pedal receiver has a magnetic charging port. Just place the transmitter on it to start charging—no plugs needed. The magnetic connection is secure and lets you quickly recharge during breaks.
Junction Box with Buffer
A built-in Send/Return loop, Input/Output interfaces, and buffer function simplify effects connections, optimize cable routing, and ensure a stable signal, making pedalboard setup easier and neater.
DI Output to the Mixer
The B-8S also features a professional-grade DI output with a balanced XLR connection, reducing signal loss and noise while improving overall sound quality.
No additional equipment is required, making setup simple and convenient for both live performance and recording.
Receiver Power
Supports a standard 9 V / 500 mA or 12 V / 500 mA (center-negative) power supply used by most pedals. It is recommended to use the power adapter included in the package to reduce noise and ensure stable, clear audio.
