NUX B-3RC Rechargeable Wireless Microphone System 2.4GHz
The NUX B-3RC is a self-contained rechargeable 2.4GHz wireless microphone system with an XLR plug-in transmitter and receiver, an NDM-4 dynamic cardioid microphone and a charging carry case, giving singers, presenters, fitness instructors and content creators a simple, cable-free microphone setup.
The NUX B-3RC is a compact, self-contained wireless microphone system that is quick to set up and easy to carry. The transmitter plugs straight onto the bottom of the supplied NDM-4 dynamic microphone, and the receiver plugs into a mixer, speaker or camera input. Switch both on and you are ready to go. It suits singers, MCs, presenters, teachers, fitness instructors, buskers and video creators who want a wireless mic without the complexity of a traditional system.
Plug In and Go
The transmitter and receiver both use standard XLR connections. The transmitter is XLR female, so it fits onto the NDM-4 or any other XLR dynamic microphone. The receiver is XLR male, so it plugs into a mixer channel, an active speaker or a DSLR camera aux input. The system can also be used without the microphone to send a mixer output wirelessly to an active speaker. Please note it is designed for dynamic microphones and does not provide phantom power.
Stable 2.4GHz Wireless
The B-3RC works in the 2.4GHz band, which means it can be used alongside conventional VHF and UHF wireless systems. Auto-pairing finds the most stable frequency within your chosen channel and connects both units on it. There are 6 channels to choose from, each with multiple frequencies to hop between, and a digitally encoded signal helps keep the connection reliable. Range is up to 30m, and latency is under 4.8ms.
Charging Case with Built-In Power Bank
When you have finished, the transmitter and receiver sit in the custom charging case, which has an internal power bank to recharge both units. The case itself charges via USB-C and has battery status indicators. A full charge gives around 3.5 hours of operation.
NDM-4 Dynamic Cardioid Microphone
The supplied NDM-4 is a dynamic cardioid microphone, which focuses on the voice in front of it and helps reduce background noise and feedback. It is a good everyday mic for speech and vocals.
