NUX B-7Pro｜Stereo Wireless In-Ear Monitor System｜Wireless In-Ear Monitor System

The NUX B-7 PRO is a personal professional wireless in-ear monitor system featuring automatic matching, a 2.4GHz operating frequency band, and high-quality stereo sound with a 24-bit/48kHz sampling rate.

It has a transmission range of up to 50 meters and very low transmission latency.

Features

• High-quality stereo monitoring
  The B-7 PRO supports stereo signal transmission in the 2.4GHz band. This is a globally interference-free broadcast range, allowing you to use it anywhere without being affected.
  With a 24-bit/48kHz sampling rate, you can enjoy high-quality sound.
  
• Fully automatic pairing
  Pairing is very simple; just turn on the transmitter and receiver, and they will pair within seconds. Each wireless system has a unique pairing algorithm that automatically detects and pairs with each other.
  
• High-definition color LCD screen
  The B-7 PRO is equipped with a high-definition color LCD screen, making it easy to view screen information when used on stage.
  
• Long distance, low latency
  The B-7 PRO wireless system uses the latest transmission technology to provide you with optimal transmission performance. When you set the transmission to LOWLATENCY, the transmission latency can be as low as 7.3ms.
  The wireless transmission range can reach 50 meters.
  
• Stable anti-interference mode
  To achieve optimal performance, you can adjust the transmission parameters between low latency and stability.
  To avoid interference, please check TX.&Are there any Wi-Fi devices around the RX? For the TX...&For the RX, it is best to keep a distance of 0.8 to 1.0 meters from any other 2.4GHz device to obtain the best performance.
  
• Ultra-long battery life
  The B-7 PRO TX and RX models feature a large built-in lithium-ion battery, providing up to 6 hours of battery life.
  You can easily place the RX on top of the TX to charge it.
  
• Audio recording
  Connect the B-7 PRO's TX (transmitter) to your phone or computer via USB interface to use the B-7 PRO's recording function.
  When you are performing on stage with an orchestra, you can record all incoming sound while wirelessly monitoring.
