Product Features:

●All-digital network conference technology, in line with IEC60914 international standards;

●Developed based on digital network architecture with built-in high-performance CPU processor for faster processing speed and better sound quality;

●Networked collaborative management, the system host can set the IP address, and control the PC computer and host between the use of advanced TCP/IP networked connection, such as network access WIFI, PC and host wireless control management can be achieved;

●Multiple conference hosts can be used separately as independent conference systems, and can be easily expanded to form a large conference system to achieve flexible multi-room configuration functions;

●The host can realize real-time audio interconnection of large conference or multiple conference rooms through the optional AoIP module, which supports mainstream network audio protocols;

●Built-in high-speed DSP processor, based on artificial intelligence self-learning algorithm developed auto feedback control (AFC) and auto noise cancellation technology (ANC), the feedback signal caused by whistling deep learning analysis, quickly remove the repetitive signal caused by whistling, learning analysis of environmental noise and background noise and current sound, etc., to remove useless noise;

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

●Support line "hot plugging", no need to power off during the meeting, can add microphone access to the system at any time;

●With the camera tracking host, the camera can be automatically tracked, support the preset panoramic position, but also access to the central control to achieve camera tracking;

●Adjustable directivity with the microphone, supporting five polar patterns: Omni-Directional, Cardioid, Super Cardioid, Strong directional, Figure-of-Eight, etc.;

●Built-in real-time clock, perpetual calendar function, can display the current time on the conference host and conference terminal, convenient for the participants to view;

●2-way audio external line input and 2-way audio line output, 1-way balanced output;

●4-way 8-core aviation connector, can form 2 groups of hand-held ring wiring method to ensure a more stable system;

●Front panel 3.5" wall control screen for conference host management and design, convenient and efficient, while the following information can be set and displayed:

a: Four modes of speech: Normal mode, FIFO mode, Free mode, Apply mode

b: Speaking mode limit function: the number of speaking units 1, 2, 4, 6 adjustable, the chairman of the unit and VIP units are not limited.

c: System volume adjustment, high and low sound adjustment.

d: (AFC) Auto feedback control on and off

e: (ANC) Auto noise cancellation on and off

f: System setup and view host IP address, Chinese and English selection, status view

g: ID settings and help

●Connected to a computer with the system control software, with more functions

a: The software can realize the function of preparing before the meeting, managing during the meeting and organizing after the meeting.

b: Check-in function can be initiated.

c: Check the microphone line condition

d: VIP unit can be set through the software, the VIP unit switch is not limited by the number of simultaneously open conference units and speaking mode

e: Host and speaking microphone for interconnection, such as tea, pen and paper requests
