NUX B-4 Wireless Microphone Transmitter Receiver System for Speaker Camera Amp Audio Interface 2.4G Portable Wireless System Rechargable
NUX B-4, a wireless microphone system tailored for those who want to get rid of the shackles of wire, can enjoy wireless fun with a simple setup.
1, small size, easy to carry.
The B-4 wireless microphone system defaults to the first channel as the preferred pairing channel. If you want to use other channels, please follow the steps below to complete the setup:
(1). Turn on the receiver and transmitter.
(2). Connect the receiver and transmitter to the microphone and mixer, respectively.
(3). Use the channel switch button to unify the receiver and transmitter channel adjustments.
(4). Wait for a while until you see the receiver's status indicator turn blue.
3. Use environment.
Due to the openness and convenience of the 2.4 GHz band, more and more consumer electronics products have begun to use this band. In order to avoid signal crosstalk, please keep at least 3 meters away from other wireless RF devices (eg 2.4GHz wireless router) when using B-4. (or set the router to 5.8GHz)
4, battery charging and sleep mode
When the receiver or transmitter is less than 10% charged, the B-4 will automatically alarm and automatically enter sleep mode. At this point, you need to charge the body using the included charging cable.
The status indicator will remain red while charging, and the status indicator will turn blue when the battery is fully charged.
If there is no signal input or no microphone inserted for 30 seconds, both the transmitter and receiver will enter the low power mode. When there is a signal input, both the transmitter and receiver will resume normal operation immediately.
If there is no signal input for 1 hour, both the transmitter and receiver will enter deep sleep mode. In deep sleep mode, you need to wake up the receiver and transmitter by pressing the CHANNEL button or reboot to resume normal operation.
