Product Introduction
Specification and parameters of the main control unit of the wireless conference system
I. System Description
This system is a wireless conference system operating in the UHF frequency band. It is fully digital-controlled and has 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. The system is easy to operate, does not require engineering installation, and is economically practical. It is the preferred choice for conference engineering.
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.
Using a unique new type of anti-noise single-direction high-sensitivity capacitor microphone core, the conference sound is made nearly 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.
For the conference application, an independent data communication algorithm has been developed. Within the signal range, the system response speed is not affected by the number of attendees.
Users can flexibly add or reduce the number of observer units. The default system observer unit capacity at factory is ≤ 255 (including 1 chairman).
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 conference unit and an idle time of over 20 hours.
Either a regular 5th-number battery or the original lithium battery provided by the manufacturer can be used. The accompanying charging box is equipped with an intelligent charging management circuit, which effectively protects the battery, extends its service life and ensures safety.
The large-screen LCD display and the hierarchical menu design make the operation simple and convenient. It also has various 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, which is grand and elegant. The peripheral unit is made of engineering plastic and features a novel exterior design. It is equipped with an internal antenna, making it both beautiful and appropriate.
The main control unit is equipped with a USB recording/speaking module, which enables USB recording/speaking functionality. It can also be connected via Bluetooth to third-party Bluetooth devices and simultaneously play the music from those devices.
