System Composition:

The system consists of a conference unit system, video matrix system, central control system, and professional sound reinforcement system.

System Function:

• Audio Pickup: The system adopts a 2.4G wireless conference system, utilizing the ISM frequency band with 2.4G full-digital frequency-hopping (DSSS) modulation technology, ensuring strong anti-interference capability and full coexistence with WiFi.  The system features automatic camera tracking and video switching functions, as well as one-touch control of equipment, lighting, air conditioning, and curtain switches. It supports three speech modes: FIFO (First In, First Out), Normal Mode, and Chairman Mode, with a maximum of four microphone units active simultaneously, facilitating orderly meeting management. This system does not require complex cable installation and can be used without any frequency application during installation and operation. Its advanced 2.4G frequency-hopping modulation communication technology and digital transmission technology significantly reduce interference, ensuring stable system operation. With its unique 2.4G transmission characteristics, digital transmission technology, and comprehensive communication protocol, the system maximizes the security of conference content.

• Control Section: The system utilizes a digital mixer, digital audio matrix, and feedback suppressor to manage overall system control, ensuring clear sound reproduction without distortion or feedback. Additionally, various audio effects processing functions further enhance the audio experience.

• Sound Reinforcement System: Equipped with four 250W professional speakers, providing full venue coverage.
