Product Description:

Kd-MF-08 ~ Kd-MF-72 small and medium-sized HD multi-format matrix series, use rack-mount pure hardware architecture. Input board, output board, fan, power supply are of modular design. Input and output board hot swap recovery time ≤2s, startup time ≤10s. High-performance multi-signal, multi-format modular plug-in matrix system with flexible configuration of input and output boards. As the transmission signal image no compression, no loss, no distortion, the transmission signal process high-definition, real-time, no delay features, to achieve the real "full HD" signal, making it output high-quality non-jitter signal image.

The matrix adopts a plug-in structure, making installation flexible. Input and output boards can be arbitrarily selected from a variety of signals, including 12/3G-SDI, HD-SDI, SD-SDI, HDMI, DVI, VGA, YPbPr, CVBS, HDBaseT, and optical fiber. The output of each channel can freely choose the input of any channel for conversion and switching, and will not interfere with other outputs. Bit rate can reach 18Gbps, and the resolution can reach 3840×2160@60Hz at max.
