Overview
Thank you for choosing the NUX B-6 PRO wireless system for your wind instrument!
The B-6 PRO is a premium wireless transmission system engineered specifically for wind instruments. Operating on the globally available 2.4GHz frequency band, it features automatic pairing and channel detection for effortless setup—simply power on the transmitter and receiver, and they pair in seconds.
Delivering 24-bit/48kHz audio with an advanced algorithm, the B-6 PRO ensures stable, high-quality sound with ultra-low latency, as low as 3.6ms, and a transmission range of up to 50 meters (165 feet). Tailored frequency response curves are included to suit various wind instruments, enhancing tonal accuracy and performance.
Lightweight and easy to install, the B-6 PRO is designed primarily for soprano, alto, and tenor instruments but is also compatible with trumpets and other wind instruments. Its secure clip-on design ensures it attaches comfortably to the instrument without interfering with playability, solving common sound-capture challenges. For added convenience, the transmitter (TX) can be docked on the receiver (RX) for charging when not in use, making it an ideal solution for both practice and performance.

Operating Instructions
Automatic Pairing
Each B-6 PRO set is preset with a pairing ID from the factory. Once the receiver and transmitter are turned on, they will quickly pair within seconds and automatically establish a stable connection on the best transmission channel.
- Turn on the power switches for the TX (transmitter) and RX (receiver). They will automatically recognize each other and complete the pairing process within a few seconds.
- The RX (receiver) screen will display information such as the signal input level, the quality of the wireless connection, and the battery status of both the TX (transmitter) and RX (receiver).
- Secure the TX (transmitter) to the mouthpiece using its rubber clip (for details, please refer back to the TX introduction). At this point, you can begin using the device.
- You can also use the footswitch to control the tuner or toggle the boost effect, among other functions, which can be customized in the menu.
Manual Re-Pairing of ID
Each B-6 PRO set is preset with a pairing ID from the factory. If you need to re-pair the ID or pair the RX (receiver) with another B-6 PRO TX (transmitter), please follow these steps:
- Turn on the power for the RX (receiver); the screen will display “Scanning.” Press and hold the “Back” button, and the screen will show “Pairing.”
- Turn on the power for the TX (transmitter), then press the “Main Button.” The TX (transmitter) and RX (receiver) will begin to pair with each other.
- Once the pairing is successful, the screen will display “PAIRED”.
Connection Scenarios
- Connect the RX (receiver) to an amplifier or mixing console.
- Connect the RX (receiver) to an amplifier or mixing console. You can also integrate your effects loop into the RX (receiver) by using the send/return ports.
TIPS：If noise occurs when connecting the RX to a computer with a USB cable and a speaker via the 1/4 inch OUTPUT jack, in this case, please try to connect to the speaker via the “DI OUT” to avoid the noise issue.
Charging the TX (Transmitter)
There are two ways to charge the transmitter:
- Charge the TX (transmitter) using the RX (receiver). Turn on the RX (receiver) and place the TX (transmitter) in the magnetic charging position. The TX (transmitter)’s LED indicator will glow red while charging.
- Charge the TX (transmitter) with a 5V/500mA adapter using the USB-C port.
Charging the RX (receiver)
The B-6 PRO comes with a DC 9V 1.2A power adapter. Plug it into the RX (receiver)’s DC port to charge the device.
CAUTION
Please only use the original DC 9V 1.2A adapter to charge the B-6 Pro’s RX. If you use an uncertified adapter to charge the RX, it might cause damages to the circuit of the product.
CAUTION
The USB-C port is not for charging!
Tips and Methods to Improve Wireless System Performance
If you experience interference or disconnection issues while using the B-6 PRO, try the following methods:
| For optimal transmission performance, check for nearby Wi-Fi devices and set the B-6 PRO to the best position between “Low Latency” and “Stable” modes. |
| Ensure the RX (receiver) is fully charged and powered on. |
| Make sure there are no large objects obstructing the signal transmission between the TX (transmitter) and RX (receiver). |
| Reduce the distance between the TX (transmitter) and RX (receiver). For example, on stage, you can place the RX (receiver) close to the TX (transmitter) and use a long cable to connect to the mixing console or speaker. |
| When using two or more sets of wireless systems, ensure that there is at least 1 meter of separation between each TX (transmitter) and RX (receiver) pair. |
| Keep the RX (receiver) away from Wi-Fi access points, computers, Bluetooth devices, or other 2.4 GHz signal sources. |
| Turn off unnecessary Wi-Fi on computers, phones, and other portable devices. |
| Avoid high Wi-Fi traffic activities, such as downloading large files or watching movies. |
| Avoid placing the TX (transmitter) and RX (receiver) near metal surfaces or other high-density materials. |
| During sound checks, mark “blind spots” where the signal is weak, and try to avoid these areas during performances. |
| The optimal operating distance is 10m(33 feet) to 35m(115 feet). |
