4K 8x8 Audiovisual Matrix Switcher M4K08

1. Adopt plug-in structure, with the number of input channels and output channels optional.

2. With optional HDMI, DVI, VGA, SDI and other interfaces, support full seamless output.

3. When the HDMI signal is output, it supports a variety of common resolutions such as 800*600~4K@30Hz.

4. Support 7.1 channel HDMI signal input, and support Dolby and other formats for audio.

5. Select the output resolution according to the display device, which can be set on the panel or the board.

6. Fully support interlaced/progressive, 25-60HZ and other digital signal inputs, and output in the set format.

7. Equipped with the auto calibration function (Auto adjust) for the input end, which can perform center correction for some non-standard digital signals according to the luminance component signal.

8. Support stereo audio separation output for each output, especially suitable for various remote video conferences and other occasions.

9. Signal processing and full conversion are 

Fully adopt FPGA programmable logic array for signal processing and full switching, in RGB444 format, without any color loss, with the effective signal bandwidth of 6G for a single channel.

10. Adopt high-speed digital switching technology to perfectly solve the phenomenon of crosstalk, ghosting and smearing. 100% true reproduction of the video effect of the input signal.

11. Support HDMI2.0 (partial), support 4KP@30/1080@60 full HD signal.

12. Adopt the HDMI2.0 interface for the video signal input, and the HDMI2.0 interface for the output end.

13. Long line drive capability: The input has automatic equalization, which can effectively reduce the deterministic jitter (ISI) caused by line transmission. The output has a pre-emphasis function, so that the receiving end can still receive signals after long-term transmission; the input supports receiving delay, and the effective time compensation should be performed when the differential pair lines are not equal in length.

14. Support HDCP (High-bandwidth Digital Content Protection) technology.

15. With power-off memory function and on-site memory function: With power-off on-site protection function; can save and recall 18 switching states.

16. When using the supporting software, it has the functions of input cropping and partial enlargement.

17. Input and output cards: Each board card has 2 channels.

18. With luxurious silicone buttons and luminous indication function, the current switching information can be obtained directly through the button backlight, easy to operate.

19. With 1 RS-232 communication interface and 1 network communication interface.

20. With built-in international universal power supply.
