This high performance Ultra HD live production system is built for demanding environments where extensive routing, advanced layering and broadcast precision are essential. Its four bank architecture provides deep switching flexibility, allowing operators to manage complex shows that require multiple simultaneous mixes, advanced transitions and layered effects. The compact rack mounted chassis includes an integrated control panel with an LCD display, enabling direct operation for setup or emergency switching, while offering immediate visual feedback of program output and system status. This design supports both studio installations and mobile production workflows where reliability and adaptability are critical.
A key strength of this system lies in its forty standards converted 12G SDI inputs. These connections support a wide range of Ultra HD formats and ensure that every source automatically matches the required frame rate and resolution. This allows cameras, graphics engines and playback devices to be used seamlessly, regardless of their native output. Twenty four dedicated 12G SDI outputs provide versatile routing to monitors, recorders, media servers and transmission paths. The unit also includes multiple multiview outputs, enabling operators to configure detailed monitoring layouts that display numerous sources simultaneously with clarity suited for Ultra HD workflows.
Advanced real time processing expands the creative potential of the system. Four independent DVEs allow repositioning, resizing and layering of video sources for dynamic picture compositions. Sixteen ATEM Advanced Chroma Keyers provide precise keying performance, ideal for virtual sets, green screen work and complex graphical overlays. Two SuperSource processors deliver additional multi‑layer compositing capabilities by combining multiple sources into arranged layouts, making them suitable for multi‑participant interviews, panel discussions and sophisticated on air designs. These internal tools reduce reliance on external hardware, keeping configurations efficient and integrated.
Professional audio features complement the video capabilities. The built in Fairlight mixer includes advanced processing such as compression, limiting and equalisation on each channel, ensuring well balanced sound across large productions. Integrated talkback allows communication with camera operators and crew through standard broadcast workflows. Ethernet connectivity supports software control surfaces or optional hardware panels, enabling flexible operation across large control rooms or production teams. Quiet thermal management ensures stable performance even during long broadcasts or in compact control environments.
This comprehensive Ultra HD system offers exceptional scale, precision and creative control, making it a strong foundation for major live productions, studio broadcasts and technically demanding event environments.
