NUX B-6 PRO Wireless System for Wind Instruments

Overview

Thank you for choosing the NUX B-6 PRO wireless system for your wind instrument! The B-6 PRO is a high-quality wireless transmission system specifically designed for wind instruments. It operates in the globally available 2.4 GHz frequency band and features automatic pairing and channel detection for seamless configuration: simply turn on the transmitter and receiver, and pairing occurs within seconds.

The B-6 PRO utilizes an advanced algorithm providing 24-bit/48 kHz audio quality, ensuring stable, high-fidelity sound with an extremely low latency of just 3.6 ms and a transmission range of up to 50 meters. It also offers custom frequency response curves tailored for different wind instruments, ensuring precise tonal tuning and high performance.

The B-6 PRO is lightweight and easy to install. It is specifically designed for soprano, alto, and tenor saxophones but can also be used for trumpets and other wind instruments. Its reliable clip-on design ensures it can be comfortably attached to the instrument without affecting playability, solving common sound pickup issues. For added convenience, the transmitter (TX) can be docked to the receiver (RX) for charging when not in use, making it an ideal solution for both practice and performance.

Features

TX (Transmitter)

Interface & I/O

The TX unit includes:

• Main Button: A button with an integrated display. Press to cycle through 'FAVORITE EQ' presets. Press and hold to turn the TX (Transmitter) on/off. If paired with the RX (Receiver), press and hold for 1.5 seconds to mute the TX (Transmitter); press again to resume normal operation.
• Charging Contacts: Used to connect to the RX (Receiver) for charging.
• USB-C Port: This port serves two functions: connecting the microphone for audio transmission and emergency charging of the transmitter.

Status Indicators

Main Button Status Indicator:

• Battery Status: Green (Battery > 75%), Orange (75% ≥ Battery > 50%), Red (50% ≥ Battery > 15%), Red blinking (15% ≥ Battery > 0%).
• Pairing Status: Green (Successful pairing with RX), Green blinking (Pairing with RX in progress), Red blinking (Not paired with RX), Red (Muted).

Installation

Step 1: Plug the USB-C connector of the gooseneck microphone into the USB-C port on the TX (Transmitter) until you hear a 'click'. The connection is now secured.

Step 2: Press the 'ears' on both sides of the transmitter to open the rubber clip, then attach it to the edge of the instrument's bell (e.g., saxophone bell).

Step 3: Adjust the gooseneck downwards so the microphone is positioned centrally in front of the instrument's bell at an optimal distance.

RX (Receiver)

Interface & I/O

The RX unit features:

Operation

Automatic Pairing

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

1. Turn on the power switches for TX (Transmitter) and RX (Receiver). The devices will automatically detect each other and complete pairing within seconds.
2. The RX (Receiver) display will show information such as signal input level, wireless connection quality, and battery status of both TX and RX.
3. Attach the TX (Transmitter) to the instrument's bell using the clip (refer to TX introduction for details). You can now use the system.
4. In addition to other functions adjustable in the menu, the footswitch can be used to control the tuner or toggle the boost effect.

Manual Re-pairing

Each B-6 PRO set is factory-preset with a pairing ID. If you need to re-pair the ID or pair the RX (Receiver) with a different B-6 PRO TX (Transmitter), follow these steps:

1. Turn on the RX (Receiver). The display will show 'Scanning'. Press and hold the 'Back' button. The display will show 'Pairing'.
2. Turn on the TX (Transmitter) and press the 'Main Button'. The TX (Transmitter) and RX (Receiver) will pair with each other.
3. Upon successful pairing, the display will show 'PAIRED'.

Connection Scenarios

Scenario 1: Connect the RX (Receiver) to an amplifier or mixer via the 6.35mm jack output.

Scenario 2: Connect the RX (Receiver) to an amplifier or mixer. You can also integrate your effects loop into the RX (Receiver) via the Send/Return connectors.

TIP: If noise occurs when connecting the RX (Receiver) to a computer and amplifier via the 6.35mm jack output, try connecting the amplifier via the 'DI OUT' to avoid noise.

Charging and Maintenance

Charging the TX (Transmitter)

There are two ways to charge the transmitter:

1. Charge the TX (Transmitter) via the RX (Receiver). Turn on the RX (Receiver) and place the TX (Transmitter) in the magnetic charging position. The LED indicator on the TX (Transmitter) will glow red during charging.
2. Charge the TX (Transmitter) via the USB-C port using a 5V/500mA power adapter.

Charging the RX (Receiver)

The B-6 PRO comes with a 9V/1.2A DC power adapter. Plug it into the DC 9V port of the RX (Receiver) to charge the device.

CAUTION! Always use the original 9V/1.2A DC power adapter to charge the B-6 PRO receiver. Using a non-certified adapter may damage the circuitry.

CAUTION! The USB-C port is not intended for charging!

Tips and Methods for Improving Wireless System Performance

If you experience interference or connection problems while using the B-6 PRO, try the following:

• 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.
• Verify that the signal transmission between the TX (Transmitter) and RX (Receiver) is not obstructed by objects.
• Reduce the distance between the TX (Transmitter) and RX (Receiver). On stage, for example, you can place the RX (Receiver) near the TX (Transmitter) and use a long cable to the mixer or speakers.
• If using two or more wireless systems, ensure there is at least a 1-meter (3 ft) distance between each TX (Transmitter) and RX (Receiver) pair.
• Position the RX (Receiver) further away from Wi-Fi access points, computers, Bluetooth devices, or other active 2.4 GHz sources.
• Disable unnecessary Wi-Fi connections on computers, mobile 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 soundcheck, identify 'dead spots' where the signal is weak and try to avoid these areas during the performance.
• The optimal operating distance is 10 to 35 meters (33 to 115 ft).

Settings and Customization

Favorite EQ Curves

The B-6 PRO offers 13 preset EQ curves tailored for various wind instruments:

• Soprano Saxophone 1: Custom-tailored for soprano saxophones, delivering a full, brilliant tone that cuts through excellently. Recommended microphone position: on-axis with the bell.
• Soprano Saxophone 2: Specifically designed for soprano saxophones to reduce the emphasis on high frequencies caused by direct pickup from the bell. The sound is natural and soft, offering a realistic listening experience. Recommended microphone position: on-axis with the bell.
• Alto Saxophone 1: Custom-tailored for alto saxophones, providing a clear and full sound with added texture and air. Recommended microphone position: off-axis to the bell.
• Alto Saxophone 2: Custom-tailored for alto saxophones, offering a warm, soft, and subtle sound with added width and depth. Recommended microphone position: off-axis to the bell.
• Tenor Saxophone 1: Custom-tailored for tenor saxophones to produce a heavy and metallic sound. Recommended microphone position: on-axis with the bell.
• Tenor Saxophone 2: Custom-tailored for tenor saxophones, delivering a natural, soft, and full sound. Recommended microphone position: on-axis with the bell.
• Trumpet 1: Specifically adapted for trumpets, providing a neutral tone reminiscent of a large-diaphragm microphone.
• Trumpet 2: Specifically designed for trumpets, emulating the sound of small wireless microphones often used in live concerts, with stronger presence.
• Trumpet mute: Custom-tailored for muted trumpet applications. When using a mute, position the microphone slightly further away to simplify operation (as shown in the illustration).
• General EQ: Suitable for various wind instruments that produce a natural and soft tone.
• Flat: An unadjusted frequency curve.
• EQ1: User-defined equalizer based on the Flat curve.
• EQ2: User-defined equalizer based on the Flat curve.

NOTE: Changing the microphone position will result in tonal variations. You can adjust the microphone position between 'on-axis' and 'off-axis' relative to the bell as needed (as shown in the illustration).
