1. Adopting Zenwin's original digital audio conferencing technology, which complies with the IEC60914 international standard

2. Supports 44.1kHz/48kHz audio sampling rates, and long-distance transmission will not have any impact on sound quality

3. The host and computer can be connected wirelessly through TC/IP or network access WiFi, and the host can achieve IP based address allocation for distributed application management

4. Zenwin audio technology can achieve flexible networking or independent partitioning of multiple conference systems, and can be applied in various conference fields for expansion

5. Dante network audio interface, supports pairing with any Dante audio device, and achieves computer upper computer software control and iPad software remote control by using TCP/IP connection to set various parameter values;

6. Supports Ethernet (POE) power supply, digital signal, DSP control, and a single cable digital link system unit using a ring loop connection (1 output and 1 backup input) to ensure efficient and normal use of the system. The system is more reliable and supports line "hot plugging", allowing for the addition of microphones to the system at any time

7. In conjunction with the camera tracking host, after using the computer preset, the camera can automatically track and support preset panoramic positions

8. The system host supports dual backup output of analog and digital signals, and supports POE power supply and dual backup power supply of external 24V modules;

9. Optional external 3.5-inch wall control touch screen for conference host management and settings, convenient and efficient, and can display the following information:

a、 Time limited mode: The speaking time limit can be set to 1-60 minutes, and the speaking will be automatically turned off when the time is up. After reaching the startup quantity, if another representative unit wants to speak, it will automatically enter the request to speak registration queue.

b、 First in, first out mode: In the first in, first out speaking mode (factory preset position), after reaching the number of power on units, the first speaking unit that is turned on is turned off by the later speaking unit.

c、 Application for speaking mode: The representative unit's speech must be approved by the chairman unit or operator. In this mode, the chairman unit always remains in a normally open state.

d、 First in, first out mode; 1/2/4/6 microphones can be selected to speak simultaneously, and the chairman microphone and VIP microphone can be pre-set without restrictions.

e、 Volume adjustment of the main output

10. The system can be connected to a PC for centralized microphone management. Through software, microphone pickup gain adjustment, forced switching, speaker information registration, sign in function, microphone line detection, and software settings for VIP units can be achieved. The switch of VIP units is not limited by the number of simultaneously opened conference units or speaking modes
