The NUX B-3 is a snap-on 2.4GHz wireless system that turns any wired dynamic microphone into a wireless microphone with a plug-in transmitter and receiver.
Snap-on XLR pair: transmitter on the mic, receiver on the mixer, PA or camera.
6 channels: switchable 2.4GHz channels to avoid interference.
Under 4 ms latency: real-time sound for stage and video.
5-hour battery: USB-rechargeable with power-saving sleep mode.
The NUX B-3 is a snap-on wireless microphone system that turns a favourite wired dynamic microphone into a wireless microphone. A compact transmitter plugs directly into the microphone’s XLR output and a matching receiver plugs into a mixer, PA system, camera or audio interface input, removing the cable run entirely. It operates on the worldwide licence-free 2.4GHz band with six switchable channels, delivers high-resolution digital audio with under 4 ms of latency, and runs for up to 5 hours on its built-in rechargeable batteries, making it a practical upgrade for singers, presenters, interviewers and videographers who already own a microphone they trust.
This listing describes the original B-3 snap-on system, not the later B-3 Plus bundle or the B-3RC handheld system, which have different specifications.
Why Choose NUX B-3?
The B-3 is chosen because it keeps the microphone and simply removes the cable. Instead of buying a complete new wireless microphone, a performer keeps the dynamic microphone whose sound and handling they already know, and gains the freedom to move around a stage, a hall or a shoot location. Six channels with simple selection help avoid interference when other wireless devices are nearby, and the plug-and-play pairing means there are no menus, no rack units and no frequency licences to arrange. Battery operation with USB recharging removes the running cost and waste of disposable batteries, and a power-saving sleep mode stretches the charge when the microphone is switched off but the system is left running. With a 100-foot outdoor range and latency under 4 ms, speech and singing stay synchronised and natural, with no distracting delay.
Key Features
Snap-on XLR design: transmitter fits a dynamic microphone’s XLR output; receiver fits a mixer, PA or camera XLR input.
2.4GHz licence-free operation: worldwide ISM band with six switchable channels to avoid interference.
High-resolution digital audio: 32-bit 48kHz audio quality with 108 dB dynamic range.
Under 4 ms latency: effectively real-time sound for live performance and video.
Up to 5 hours battery life: built-in rechargeable lithium-ion batteries, USB rechargeable, with sleep mode.
100-foot range: over 30 metres line of sight outdoors for stages, halls and location shoots.
Best Suited For
The B-3 suits singers and presenters who want to roam a stage, wedding and event hosts, teachers and trainers, interviewers, and videographers recording a subject who is already miked with a dynamic microphone. It is ideal for small venues, churches, schools, conference rooms and mobile video work where a full rack wireless system would be excessive. It is designed for dynamic microphones; the transmitter does not provide phantom power, so condenser microphones that need phantom power cannot be used with it. Users who need a complete microphone included, or a multi-channel rack system for large productions, should consider a bundled or rack wireless system instead.
Setup and Connection Guide
Plug the B-3 transmitter into the XLR output of a dynamic microphone and plug the receiver into the XLR input of a mixer, PA system, audio interface or camera adapter. Switch both units on and select one of the six channels on each unit so transmitter and receiver match, then set the receiving device’s input gain as you would for a wired microphone and check levels before the performance. Charge both units over USB before a session; a full charge gives up to 5 hours of use, and leaving the microphone switched off while the B-3 runs engages the power-saving sleep mode. If interference appears, switch both units to another of the six channels. For camera use, confirm the camera’s audio input type and use the appropriate adapter, since the receiver output is XLR and some cameras need a 3.5 mm adapter, which is a separate accessory.
Frequently Asked Questions
Does the NUX B-3 include a microphone?
No. The B-3 is a snap-on transmitter and receiver pair that makes an existing wired dynamic microphone wireless. It does not include a microphone in this configuration.
Can I use a condenser microphone with the NUX B-3?
No. The B-3 transmitter does not provide phantom power, so condenser microphones that require phantom power cannot be used. It is designed for dynamic microphones with an XLR output.
How far can I move from the receiver with the NUX B-3?
The published range is over 100 feet, around 30 metres, line of sight outdoors. Walls, crowds, bodies and other 2.4GHz traffic can reduce the practical range indoors, so a clear path and a free channel give the best results.
