The B-8 Guitar Wireless System is a professional-grade solution in NUX’s Pro Series. Built on their 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.

6-Level Stability And Audio Zip/Unzip

The B-8 offers 6 levels of stability (2.5ms–8.7ms). Higher stability levels increase the number of signal transmissions, with up to 12 transmissions every 8.7ms. (Since interference is time-varying, more frequent transmissions can help avoid interference issues.)

It uses Audio Zip/Unzip technology with 24-bit/48kHz quality to ensure clear and stable sound, working in combination with 6-level stability settings. 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.

Beltpack Transmitter

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. 

Cable Tone

The TX features a cable tone simulation which is normally used for some guitar players to get a warmer sound. If you want it, you can pull the switch and turn it on.

A Multifunction Pedal Receiver

The B-8 combines multiple practical features into one unit, including wireless transmission, tuner, junction box, boost, buffer, DI functions, guitar input and a magnetic charging port for the transmitter.

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.
