The Blackmagic Design Videohub 40x40 12G is a zero-latency SDI video routing switcher designed for professional broadcast, live production, and post-production signal distribution. It features 40 inputs and 40 outputs over 12G-SDI, allowing simultaneous routing of SD, HD, UHD, and DCI 4K signals across a single compact 2RU chassis. The router supports multi-rate SDI up to 12G, internal re-clocking on outputs, and reference sync input for integration into genlocked facilities. It is commonly used in broadcast trucks, live event infrastructures, studios, and production facilities requiring high-density signal routing and flexible source-to-destination mapping.
Blackmagic Videohub 40x40 12G is an advanced zero latency video router that supports any combination of SD, HD and Ultra HD on the router at the same time. It has 40 12G-SDI inputs and 40 12G-SDI outputs, redundant power and reference connections in two rack units size. The large full HD LCD lets you see video before routing and clearly displays routing labels and video standards. Routing can be performed by direct button selection and using the large spin knob control that has an electronic clutch. It also features SDI re-clocking, external Ethernet control and supports all SDI video standards up to 2160p60.
