The multi-format AV-HS400 live switcher is an all-in-one system that easily integrates into existing HD/SD workflows, flawlessly mixing HD and SD video sources. With a built-in MultiViewer image preview, expandable HD/SD architecture, 3D digital effects and a host of other advanced features, the HS400 provides all the functions you need for superb results. The HS400's built-in MultiViewer can output 4, 6, or 10 images from different sources to a single high-resolution display, eliminating the need for multiple HD source and preview monitors. For added creative flexibility, the switcher offers a broad selection of wipe patterns including 3-D digital effects and features a high-quality chroma key for applications such as green screen in broadcast and production. The HS400's modular architecture comes standard with four HD/SD-SDI inputs and four HD/SDI outputs and can be expanded to support up to 8 inputs and 8 outputs with optional I/O boards. The switcher has a built-in, switchable 10-bit frame synchronizer for each input, for glitch-free switching, even with non-synchronous sources such as Blu-Ray DVD players or remote camera feeds.
