Benefits of 2.4G Wireless Digital Conference System
Stable Tranmission: The wireless audio transmission is stable and free from distortion, ensuring no signal loss or interference even in complex wireless environments.
Efficient Allocation: The system is designed with rational wireless signal distribution to prevent signal attenuation or insufficient coverage due to excessive concentration or blind spots.
Scalability: The system offers excellent scalability, allowing flexible addition or reduction of microphones, receivers, audio equipment, and other devices based on the size of the conference room, number of participants, and specific requirements.
User-Friendly Operation: The 2.4G wireless digital conference system features a carefully designed interface with intuitive controls, avoiding complicated procedures, allowing conference hosts, participants and technical support staff to easily master the system.
The 2.4G wireless digital conference system consists of a conference unit system, video matrix system, central control system, and professional sound reinforcement system.

2.4G Wireless Digital Conference 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.
