• Digital network conferencing technology, simple and stylish appearance, complying with electrical safety standards, line anti-interference and anti-static design

•Based on IoT application design, digital network architecture development, high-performance CPU processor, high-speed parallel processing, and low latency;

• Wired and wireless integration technology, a wireless microphone unit can be added at any time to achieve flexible speaking through the microphone;

• Adopt advanced TCP/IP network connection method, automatically obtain IP address or manually set IP, no need for complicated settings, plug and connect. If the network is connected to WIFI, wireless control and management of PC and host can be realized, and networked collaborative management can be realized. Distributed applications and management;

• The host supports three audio backups, namely microphone digital-analog backup, hand-in-hand ring backup, and host digital-analog backup. All adopt seamless audio backup to ensure that the audio signal does not drop;

• Embedded machine self-learning algorithm technology can use machine self-learning to determine whether the signal is background noise or system local noise, thereby starting the noise reduction algorithm ANC. At the same time, it also has environmental sound environment learning, which can judge the feedback signal and activate the suppression function AFC before the system howls, thereby suppressing the system howling.

• Ring-shaped hand-in-hand connection technology, the failure or replacement of one microphone will not affect the normal operation of other microphones in the system, making the system more reliable;

• Supports "hot plugging" of lines, no need to cut off the power during the meeting, and microphones can be added to the system at any time

• Cooperating with the camera tracking host, it can perform automatic camera tracking, support preset panoramic positions, and can also be connected to the central control to achieve camera tracking;

• The unit has an arbitrarily assigned ID address, which facilitates installation and avoids duplication of ID addresses.

• With the AOIP network module, real-time audio interconnection for large conferences or multiple conference rooms can be easily achieved. It uses mainstream standard network protocols to transmit audio signals with low latency and high efficiency. It can also be easily expanded to form a large conference system. Achieve flexible multi-conference room configuration function;

• Initiate check-in, voting, voting functions, and project the results on the big screen.

• 2 audio external line inputs and 2 audio line outputs, 1 balanced output;

• 2-way 8-core aviation connector can form 2 sets of hand-pull ring wiring methods. The connector is anti-oxidation and has a locking link to ensure reliable contact and does not fall off. The contacts are blocked from the air and are designed to be anti-oxidation. Reduce the risk of system instability caused by oxidation to ensure a more stable system;

• External wall controller is connected to realize on-site touch screen management, including conference mode, microphone status, demand service, microphone management, etc.

• The 4.3-inch touch screen on the front panel is used for conference host management and settings, which is convenient and efficient. It can also set and display the following information:

a. Five speech mode options: normal mode, first-in-first-out mode, free mode, application mode, voice wake-up mode

b. Speech mode restriction function: The number of speech units is adjustable from 1, 2, 4, and 6. The chairman unit and VIP unit are not restricted. PTT press and hold speech mode;

c. System volume adjustment, treble and bass adjustment

d. AFC adaptive feedback suppression on and off,

e. ANC automatic noise reduction on and off

f. System settings can set and view the host IP address, Chinese and English selection, status viewing, ID setting and help

g. Wireless microphone status query

h. Built-in real-time clock and perpetual calendar function, which can display the current time on the conference host and conference terminal for the convenience of participants.

• Connect to a computer and use it with system control software to have more functions：

a. The software can realize pre-meeting preparation, mid-meeting management, and post-meeting organization functions.

b. Microphone management can be centralized, such as microphone pickup gain adjustment, forced switch, and speaker information registration

c. Can initiate sign-in, voting, and voting functions

d. Check the microphone line status

e. The VIP unit can be set up through the software. The switch of the VIP unit is not limited by the number of conference units turned on at the same time and the speaking mode.

f. The host computer and the speaker microphone are interconnected, such as requests for tea, pen and paper, etc.
