WDC-903

Wireless Conference Discussion System

Product Description

WDC-903 digital wireless conference discussion system, with professional appearance design, perfect circuit composition and stable functional characteristics, can be cooperated with VTS-2000 automatic video tracking system and central control system to achieve functional diversification of modern high-tech conference. The data instruction of this wireless conference discussion system is transmitted by LoRa protocol. Audio works in UHF band. High fidelity circuit design can produce high quality sound effect. The system has anti-interference protection, which can effectively block the influence of computers, mobile phones and Bluetooth wireless devices in the environment. It is fully applicable to local government departments, business conference rooms, business venues and international conference centers.

Performance Introduction


LoRa Communication Protocol and UHF Audio Transmission Protocol

Using LoRa protocol 433Mhz wireless control signal, U-segment audio transmission technology.


Dante audio transmission protocol

With Dante interface, it can communicate with any device with Dante to transmit audio.


Multiple meeting modes

①Limited time mode ②First in first out mode ③Application mode ④Voice control mode


Extensibility

With antenna interface, it can be used together with the antenna system of the power card, so the transmission signal is very strong. Any number of wireless conference systems can be installed in the same building. It is used together with VTS-2000 automatic video tracking system to realize the automatic video tracking function of the conference. Equipped with RS-232 interface, it can connect various central control devices.


Automatic Power-on

The conference unit can automatically select or manually start the power supply. When the automatic start is selected, the host will send instructions to the conference unit when the host is started, and the conference unit will automatically turn on the power supply after receiving the instructions in the working mode.


Automatic Frequency Selection

With [AFS] (Auto Frequency Selection) function, enter the setup menu and select AFS function, the receiver will auto-scan and lock on to an open interference-free frequency.
