Wireless. Effortless
B-3RC has auto-pairing and channel group selection. Plug the Transmitter (TX) into your mic, the Receiver (RX) into the PA system, and you are good to go. The units will automatically detect each other and choose the best channel from all 6 channels.
Delivering detailed consideration for performers’ control needs, B-3RC allows you to swiftly mute from the Transmitter (TX)’s power switch button.
With a relatively neutral frequency response, the sound design delivers balanced performance across low, mid, and high frequencies. It avoids excessive bass boost that could cloud clarity, ensuring a clean and pleasant tone for music playback, instruments, and vocals alike.
The Transmitter (TX) and Receiver (RX) measure just 80mm in length and weigh only 36g each.
Long-lasting lithium battery brings up to 3.5 hours of using time on one charge. With the charging case, charging could never be easier. And you can charge the case through the USB-C port.
The LED indicators on the TX, RX, and charging case allow you to intuitively monitor the battery state.
