This advanced live production system is architected to deliver extremely high performance for modern broadcast environments that require uncompromising Ultra HD and 8K capabilities. Built around a highly scalable four bank switching structure, it combines a dense array of professional inputs and outputs with sophisticated internal processing that allows operators to manage complex shows with ease. Its powerful electronics enable seamless operation in native 8K when needed, combining multiple processing engines to achieve the full resolution and bandwidth required for cutting edge workflows. The system integrates cleanly into professional facilities and mobile units where flexibility and reliability are essential.
This unit features forty 12G SDI inputs with full standards conversion on every channel, ensuring that cameras, graphics systems and playback devices can be mixed smoothly regardless of their native format. When operating in 8K, groups of inputs and processing features combine, allowing the system to deliver an impressive level of visual fidelity. The switcher supports a broad range of HD, Ultra HD and 8K frame rates, making it suitable for premium sports, large concerts and high profile broadcast events where resolution and fluidity must meet the highest standards. Multiple 12G SDI outputs, including aux, program and multiview feeds, support extensive signal routing and monitoring setups commonly used in large control rooms.
Creative capabilities are enhanced through four advanced digital video effects engines, which enable repositioning and layering of images in real time. Sixteen high performance chroma keyers allow precise keying for virtual environments and complex composites, while the system’s two SuperSource processors make it possible to build multi‑layered layouts for interviews, presentations or multi participant productions. These features are designed to work fluidly even when operating at the highest resolutions, ensuring consistent performance throughout demanding broadcasts.
A professional Fairlight audio mixer is integrated into the platform, offering extensive control including compression, limiting, expansion and parametric equalisation on each channel. This allows sound engineers to achieve broadcast quality mixes without external processors. The system also includes built in talkback, providing reliable communication between technical staff and camera operators. With Ethernet control, operators can work through software interfaces or hardware panels, adapting the system to facilities of any scale.
Designed for high end television production and future ready workflows, this platform delivers exceptional power, precision and flexibility for productions that require the very best in 8K live switching.
