B-3RC is a self-contained re-chargeable wireless system operating on the license-free 2.4GHz band. The XLR plug-in transmitter and receiver are supplied with the NDM-4 dynamic microphone, providing a complete wireless microphone set that can also be used with any other XLR dynamic microphone of choice. Simply plug the transmitter onto the microphone and plug the receiver into an input channel or DSLR camera aux input and switch both units on. The B-3RC system can also be used without the microphone for wireless transmission of a mixer output to an active speaker. Auto-pairing detects the most stable frequency within the selected channel and connects both units on that carrier. There are 6 channels to choose from, each with multiple frequencies to hop between and a digitally encoded signal for the best possible signal integrity. When not in use, the transmitter and receiver are stored in a custom charge case, which has an internal power bank to re-charge both units and can itself be powered or charged from a USB-C connection with battery status indicators. Operating on the 2.4GHz band means that B-3RC can be used alongside conventional VHF and UHF wireless systems.
