10. It has a compressor function to compress the dynamic range of the signal and compress the size of the output signal.

11. It has a limiter function to limit the size of the output signal to prevent the signal from being too large and damaging the sound reinforcement equipment.

12. It has a delay function to provide a maximum delay adjustment of 2000ms, which is used to adjust the delay of each output signal so that each audio signal is synchronized when it reaches the listener's ear.

13. It has an echo cancellation function for remote audio and video conferencing to eliminate echoes and increase voice clarity.

14. It has a noise cancellation function, which can effectively eliminate environmental noise such as air conditioning sound and fan sound, and improve voice clarity.

15. It has a feedback suppression function, and two processing solutions of notch filter + frequency shifter can effectively solve the problem of acoustic feedback.

16. Extremely low system processing delay, the delay is less than 3ms.

17. The panel has a 2-inch IPS true color display screen, which displays device network information, real-time level, channel mute status, matrix mixing and other status.

18. The panel has a USB interface, supports multimedia storage, and can store recording or playback.

19. Supports scene preset, import, and export, and supports 8 scenes.

20. Has the function of restoring factory settings.

21. Has an RS-232 interface, which can be used to connect to an external central control system to achieve centralized control.

22. Has an RS-485 interface, which can be connected to the central control system and camera tracking system, and can realize automatic camera tracking function.

23. Has an 8-channel programmable GPIO control interface (customizable input and output).

24. Supports channel copy, paste, and joint control functions.

25. Enternet multi-purpose data transmission and control port, which can support real-time management of single and multiple devices.

26. The audio processor has cross-platform software and can run 8 operating system versions, including Windows7/10/11, Galaxy Kylin Desktop Operating System (Zhaoxin Edition), Galaxy Kylin Desktop Operating System (Feitian Edition), macOS System, Tongxin UOS, and Ubuntu Desktop Edition Operating System.

27. The product has different control modes for PC client, mobile phone, and Android tablet. You can log in to the APP software and PC client at the same time to connect the device and realize the synchronization of multi-terminal data.

28. Supports operation and control through Android mobile phones and tablet APP software, device login, scene switching, input and output, matrix routing and channel settings.

29. Supports automatic power-off protection memory function.
