Blackmagic Videohub 40x40 12G

This large format 12G-SDI video router is built for professional facilities that require high connection density, absolute reliability and complete format flexibility. Designed in a robust two rack unit chassis, it supports simultaneous routing of SD, HD and Ultra HD signals, allowing modern mixed format workflows to operate without compromise. Zero latency switching ensures live productions, studios and OB environments maintain perfect timing across complex signal paths.

A standout feature is the large full HD LCD integrated into the front panel. This display provides clear live video previews of connected sources before routing, alongside easily readable routing labels and detected video standards. This visual feedback significantly reduces the risk of errors during fast paced operation. Routing can be performed directly using the front panel buttons or with the precision spin knob equipped with an electronic clutch, offering both speed and accuracy for technical operators. 

With forty 12G-SDI inputs and forty 12G-SDI outputs, the router supports all common SDI data rates from legacy SD-SDI through to full 12G-SDI. Each input automatically detects its signal standard independently, allowing different resolutions and frame rates to be connected at the same time. Full SDI reclocking on every output maintains signal integrity, reduces jitter and ensures clean distribution over long cable runs.

For mission critical installations, redundant power supplies are built in, increasing operational security and uptime. Reference inputs support both tri sync and black burst, with a loop through reference output for seamless integration into synchronised broadcast infrastructures. External control is available via Ethernet, supporting software control panels for macOS and Windows, as well as dedicated hardware panels. A USB-C connection is included for configuration and software updates, while crosspoint settings are preserved and instantly restored after power loss. 

Combining high density routing, intuitive local control and enterprise level reliability, this solution is ideally suited for broadcast studios, central machine rooms, large live venues and post production facilities that demand performance and flexibility at scale.
