NUX B-7Pro｜ Stereo wireless in-ear monitoring system｜Wireless In-Ear Monitor System

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

The transmission range is up to 50 meters with very low transmission delay.

Features

• High-quality stereo monitoring
  B-7 PRO supports the transmission of stereo signals in the 2.4GHz frequency band. This is a global interference-free broadcast range, you can use it anywhere without being affected.
  Adopting 24-bit/48kHz sampling rate, you can have a high-quality sound.
  
• Fully automatic pairing
  The pairing steps are very simple, just turn on the transmitter and receiver and they will be paired in seconds. Each wireless system has a unique pairing algorithm, and they will automatically detect each other and pair.
  
• High-definition color LCD screen
  The B-7 PRO is equipped with a high-definition color LCD screen, which makes 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 the best transmission performance. When you set the transmission to LOWLATENCY, the transmission delay can be as low as 7.3ms.
  The wireless transmission range is up to 50 meters.
  
• Stable anti-interference mode
  To get the best performance, you can adjust the transmission parameters between low latency and stable.
  To avoid interference, please check if there are any Wi-Fi devices around TX & RX. For TX&RX, it is best to keep a distance of 0.8~1.0m from any other 2.4GHz devices to obtain the best performance.
  
• Ultra-long battery life
  The B-7 PRO's TX and RX have large built-in lithium-ion batteries that provide 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 the USB interface to use the B-7 PRO's recording function.
  When you're on stage with your band, you can record all incoming sound while monitoring wirelessly.
