The Ultimate 4K Engine for Massive Live Productions
Meet the Blackmagic Design ATEM 4 M/E Constellation 4K, a powerhouse Ultra HD live production switcher engineered for the most demanding broadcasts and live events. Housed in a compact rack-mount design, this switcher packs an incredible amount of power, transforming complex productions into seamless, professional broadcasts. It’s the ideal solution for concerts, music festivals, live sports, and houses of worship, providing the massive I/O, advanced features, and intuitive control needed to create stunning multi-camera content. Despite its immense capabilities, an innovative high-efficiency thermal system ensures it runs cool and quiet, making it perfect for any production environment.
At its core, the ATEM 4 M/E Constellation 4K is built for flexibility and scale. With a staggering 40 standards-converted 12G-SDI inputs, you can connect virtually any camera or 4K source, and each input will be automatically converted to the switcher's video standard. This eliminates the need for external converters and simplifies setup, allowing you to focus on creativity. The 24 fully assignable 12G-SDI auxiliary outputs provide complete freedom to send independent feeds to stage screens, recorders, and streaming processors. Add to that a professional 156-channel Fairlight audio mixer with EQ and dynamics on every input, and you have a complete, integrated solution for both world-class video and audio.
From complex multi-layer effects to flawless virtual sets, the creative toolset is limitless. It features 16 advanced chroma keyers, 4 independent DVEs, and 2 powerful SuperSource processors for creating sophisticated picture-in-picture compositions without tying up your primary resources. The built-in media pool stores broadcast-quality graphics and animations, ready for instant playback. Control is effortless, whether using the built-in front panel for quick access, the free ATEM Software Control for Mac and Windows, or integrating professional ATEM Advanced Panels for a traditional broadcast workflow. For modern streaming, the USB-C output functions as a high-quality webcam, ensuring instant compatibility with popular software like Zoom, Teams, and OBS.
