How NUX Intelligent Frequency-Hopping Works
Like a jazz musician who always finds the right note — when interference pops up, it instantly “changes key,” to not miss a beat...
While in use, it automatically scans the 2.4GHz band and switches to the cleaner channel when interference is detected, ensuring a stable connection and clear audio throughout your performance.
Like a motorcycle navigating through crowded traffic more easily than a truck...
NUX's advance Audio Zip/Unzip technology with 24-bit/48kHz quality to ensure clear and stable sound. The 1MHz Zip technology enhances anti-interference performance — “like a motorcycle (1MHz) navigating around traffic along a crowded highway (2.4GHz~2.483GHz) more smoothly than a truck (4MHz).” The Unzip technology preserves high-resolution sound quality without any compromise.
A Multifunction Pedal Receiver
The B-8 packs everything you need into one smart unit — wireless system, tuner, junction box, boost, buffer, DI output, and guitar input. This all-in-one design makes setup faster, keeps your stage tidy, and helps you perform more efficiently.
On-Board Tuner
Features NUX’s high-sensitivity tuner for accurate and smooth tuning. The A4 reference frequency can be adjusted from 430Hz to 450Hz, with customizable animations.
Four tuning modes available:
- Chromatic
- Guitar Standard
- Guitar Compensated
- Bass
Clean Boost up to +12dB
Increase your guitar volume and dynamics with 0 to +12dB 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.
Beltpack Transmitter w/ Cable Tone Switch
The compact beltpack clips easily to a strap or pocket. Its jack design prevents rotation and loosening—keeping the plug secure even during energetic movement.
Fits electric and electro-acoustic guitars, basses, and other instruments with pickups.
The transmitter features a cable tone simulation commonly favored by guitarists seeking a richer sound. To engage this function, simply toggle the switch.
Junction Box w/ Buffer
Make your pedalboard setup neater and easier to use by optimizing your cable routing all while ensuring stable signal.
