Product Introduction
Wireless conferencing – Main Control Unit of Wireless Conference System (UHF, 255 Units, Video Tracking, USB/Bluetooth)
I. System Description
This system is a wireless conference system operating in the UHF frequency band. It is fully digitally controlled and features multiple speaking modes. It can be connected to a video host to achieve video tracking functionality. The power supply for the observer unit can use ordinary batteries or rechargeable lithium batteries, which is both convenient and environmentally friendly. This system is easy to operate, does not require engineering installation, and is economically practical. It is the preferred choice for conference engineering.

1.1 Functional Features
The sound signal transmission is achieved through FM modulation. It offers high fidelity, a high signal‑to‑noise ratio, and no sound delay. The unique new anti‑crowd‑noise single‑direction high‑sensitivity capacitor microphone core is used, making the conference sound almost perfect.
Both the audio channel and the control channel are transmitted via wireless means, without the need for cable laying. The signal coverage area can be moved freely, making the venue layout convenient and flexible.
An independent data communication algorithm has been developed for the conference application, ensuring that within the signal range, the system response speed is not affected by the number of attendees. Users can flexibly add or remove attendees. The default system capacity for attendees at factory delivery is ≤ 255 (including 1 chairperson).
It has rotation modes of 1-2-3-4, restriction modes of 1-2-3-4, and multiple conference speaking modes exclusive to the chairman. The main control unit can be connected to a video host to achieve the video tracking function for the audience units in the venue.
Ultra‑low power consumption, with a continuous speaking time of over 8 hours for the unit and an idle time of over 20 hours; either a 5th‑grade ordinary battery or the original lithium battery provided by the manufacturer can be used. The accompanying charging box has an intelligent charging management circuit, which effectively protects the battery, extends its service life and ensures safety.
Large‑screen LCD display. The hierarchical menu design makes the operation simple and convenient. It also has many functions such as battery level display, under‑voltage warning, frequency channel and signal indication.
The main control unit is designed with an all-metal structure, presenting a grand and dignified appearance. The auxiliary unit is made of engineering plastics with a novel design and is equipped with an internal antenna, looking both beautiful and appropriate.
