The Blackmagic Design ATEM Constellation 8K is Blackmagic’s flagship, heavy-duty 2RU live production switcher. It is built for large-scale broadcast facilities, live event venues, mobile production trucks, and high-end studio environments. A standout feature is dual-mode flexibility: it operates as a massive HD / Ultra HD (4K) switcher with maximum input density, or can be combined into a native 8K switcher.  

Pulled directly from a professional, climate-controlled, smoke-free corporate broadcast facility. All units have been tested, factory reset, and are running stable firmware. Expect minor cosmetic rack-wear/scuffs on the outer casing, but front panels and technical functionality are excellent.
