Description
  • Made of integrated all-aluminum alloy material to build a 1U chassis, the overall structure is exquisite and detailed
  • For the first time in the industry, it is equipped with an 11-inch color LCD display, which can display product information in detail and enhance the overall user experience
  • Adopt new digital wireless communication technology, combined with independently developed e ncryption algorithms, to effectively prevent frequency channeling and improve anti-interference capabilities
  • Use advanced wireless frequency band management technology to rationally plan the use of frequency points and significantly reduce potential mutual interference between frequency points
  • Built-in high-quality switching power supply, wide voltage stabilization range, high efficiency, low energy consumption and anti-interference, ensuring stable operation of the equipment
  • Adopt a convenient and intuitive shuttle knob design to replace the traditional complex button operation mode and simplify the operation process
  • Supports a variety of gesture operations, enabling contactless operation and control of the receiver
  • True diversity receiving host system, each channel adopts the dual receiving mechanism of channel diversity and antenna diversity to maximize the elimination of receiving dead spots and ensure the continuous stability and reliability of signal reception
  • Supports one-click screen lock to prevent misoperation. The device will automatically enter the screen saver state after no operation, improving the aesthetics of the product
  • The antenna interface integrates 9V voltage supply capability, which can directly connect and drive the active high-gain antenna without additional power supply, improving signal capture performance
  • Supports infrared frequency binding and can be paired with handheld microphones, bodypack microphones, and wireless conference microphones
  • Supports the channel color label function and matches the color indicator light on the microphone. Users can intuitively identify the corresponding connected receiver channels through the indicator lights of different colors on the microphone, achieving simple and efficient channel identification and management
  • Supports the transmit power adjustment function, allowing users to flexibly adjust the transmit power of the transmitter according to actual application scenarios and distance requirements, ensuring the best balance between signal coverage and energy consumption
  • Clear sound quality transmission supports perfect restoration of speech: up to 96kHz sampling rate is supported, and 32kHz/48kHz/96kHz sampling rate is optional
  • Supports real-time spectrum display system, which can display frequency signal strength within the frequency band in real time
  • With automatic frequency scanning function, you can find clean and interference-free frequency points with one click
  • Audio effect adjustment function: reverberation effect mode and feedback suppression mode can be turned on
  • Support scene preset function: optional conference mode, singing mode, handheld mode and custom mode
  • Support intelligent mute mode: optionally turn on the channel mute after 0/5/10 seconds when there is no speech, and automatically turn off the mute function when speaking
  • The system interface supports bilingual display in Chinese and English
  • Support central control: volume adjustment, frequency switching, mode switching and other operations can be controlled
