The SC-390 Scaler Switcher is a highly integrated audio and video switcher. It supports YUV, YC, CV, VGA, DVI, HDMI, and 3G-SDI input as well as DVI, HDMI, and SDI video format output. It adopts our unique audio and video switching technology and is designed to meet current display equipment's requirements on high quality, high resolution videos.

Our scaler switcher supports multiple input and output resolutions. It provides panel keys for synchronous operation with PC software. This switching device also has operation memory function. In case of no operations within 10 seconds after setting, current system status will be automatically saved. In addition, our scaler switcher has temperature self-checking function. It will measure the temperature every 3 seconds and display the temperature value on the LCD screen, thus ensuring safe use.
