This advanced live production switcher delivers professional broadcast performance in a compact, rack‑mountable chassis designed for studios, mobile rigs and event environments. It is built to provide the speed and precision required for multi camera workflows while maintaining the reliability expected in continuous live operation. With ten fully standards‑converted 3G‑SDI inputs, the system accepts a wide array of HD sources without the need for external converters. Each input re‑synchronises incoming feeds automatically, ensuring seamless integration even when cameras or playback devices run at different formats or frame rates. This makes it ideal for complex productions where equipment consistency cannot always be guaranteed.
Six 3G‑SDI outputs offer flexible routing options for program, auxiliary feeds, monitors and external recorders. These outputs allow operators to distribute clean signals throughout the production chain while maintaining full control over the routing configuration. The switcher includes powerful chroma keying capabilities with four advanced keyers suitable for green screen, virtual sets and high‑quality compositing. A built‑in digital video effects processor provides smooth picture positioning for transitions, overlays and picture‑in‑picture layouts, supporting more creative production styles without additional hardware.
A sixteen‑window multiview display streamlines monitoring by combining all essential sources into a single HD output. Operators can view cameras, media players, key masks, program and preview feeds simultaneously, significantly improving oversight during fast‑paced shows. Integrated media players allow quick loading of still graphics for titles, logos or visual branding, and the unit’s onboard talkback system improves communication between directors and camera operators. USB webcam output enables direct use with software‑based streaming tools, allowing the switcher to appear as a standard video source to applications commonly used in corporate, education or online broadcasting.
Designed for both standalone use and integration with control surfaces, this model supports front‑panel operation for quick adjustments or emergency control. The efficient thermal design keeps the unit extremely quiet, making it suitable for control rooms and other noise‑sensitive environments. Its compact size and professional connectivity ensure it adapts well to both fixed installations and portable flight cases, offering dependable performance for any HD broadcast workflow.
