NUX B-6 PRO Wireless System for Wind Instruments

Introduction

Thank you for choosing the NUX B-6 PRO wireless system for your wind instrument!

The B-6 PRO is a high-end wireless transmission system specifically designed for wind instruments. Operating on the globally available 2.4 GHz frequency band, it features automatic channel detection and pairing for effortless setup: simply turn on the transmitter and receiver, and they will pair in seconds.

Delivering 24-bit/48 kHz audio using a cutting-edge algorithm, the B-6 PRO ensures stable, high-quality sound with ultra-low latency, down to 3.6 ms, and a transmission range of up to 50 meters. EQ curves tailored for different wind instruments are included, enhancing tonal accuracy and performance.

Lightweight and easy to install, the B-6 PRO is primarily designed for soprano, alto, and tenor saxophones, but is also compatible with trumpets and other wind instruments.

Operation

Automatic Pairing

Each B-6 PRO set is factory-preset with a pairing ID. When the receiver and transmitter are powered on, they will pair automatically within seconds, establishing a stable connection on the best transmission channel.

1. Turn on the transmitter (TX) and receiver (RX) using their power switches. They will automatically recognize each other and complete the pairing process in seconds.
2. The RX screen will display information such as signal input level, wireless connection quality, and battery charge for both TX and RX.
3. Attach the TX to the instrument's bell using its rubber clip (refer to TX presentation for details). You can now start using the device.
4. The footswitch can be used to control the tuner or switch the boost effect, among other customizable functions.

Manual Pairing

If you need to reassign the pairing ID or pair the RX with a different B-6 PRO TX, follow these steps:

1. Power on the RX; the screen will display "Scanning". Press and hold the "Back" button; the screen will display "Pairing".
2. Power on the TX, then press the "Main Button". The TX and RX will begin to pair.
3. When pairing is successful, the screen will display "PAIRED".

Connection Scenarios

Scenario 1: Connect the RX to an amplifier or mixer.

Scenario 2: Connect the RX to an amplifier or mixer. You can also integrate your effects loop into the RX using the Send/Return jacks.

Charging

Charging the Transmitter (TX)

There are two ways to charge the transmitter:

1. Charge the TX using the RX: Turn on the RX and place the TX on the magnetic charging spot. The TX LED will light up red while charging.
2. Charge the TX using a 5V/500mA AC adapter connected to the USB-C port.

Charging the Receiver (RX)

The B-6 PRO comes with a 9V DC, 1.2A AC adapter. Plug it into the RX's DC 9V input for charging.

ATTENTION: Only use the original 9V DC, 1.2A adapter to charge the B-6 Pro RX. Using an uncertified adapter may damage the product's circuitry.

ATTENTION: The USB-C port is not intended for charging!

Tips for Improving Wireless Performance

If you experience interference or disconnections 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".
• Ensure the RX is fully charged and powered on.
• Make sure no large objects obstruct the signal transmission between the TX and RX.
• Reduce the distance between the TX and RX. For example, on stage, you can place the RX near the TX and use a long cable to connect to the mixer or amp.
• When using multiple wireless systems, ensure at least one meter of separation between each TX/RX pair.
• Keep the RX away from Wi-Fi access points, computers, Bluetooth devices, and other active 2.4 GHz sources.
• Disable non-essential Wi-Fi on computers, phones, and other portable devices. Avoid high-traffic Wi-Fi activities like large file downloads or streaming movies.
• Avoid placing the TX and RX near metal surfaces or other high-density materials.
• During soundcheck, identify "dead zones" where the signal is weak and try to avoid them during performances.
• The optimal operating distance is between 10 and 35 meters.

FAVORITE EQ Presets

The system includes various EQ presets tailored for different wind instruments:

Note: Microphone position affects sound. You can position the microphone in-axis or off-axis to the bell according to your preference.
