The Blackmagic Design ATEM 4 M/E Constellation 4K is the ultimate flagship live production switcher, engineered for the world's most demanding 4K Ultra HD broadcasts, major live events, and large-scale studio productions. This powerhouse system features four fully independent Mix Effects (M/E) banks, each a complete production switcher in its own right, providing unprecedented layering, effects, and control capabilities. It is designed to handle massive input counts and deliver pristine 4Kp60 output, supporting the entire workflow from ingest to transmission within a fully featured, redundant, and scalable hardware frame.

Every M/E bank is equipped with multiple upstream and downstream keyers, a dedicated advanced 2D/3D DVE for complex motion graphics and picture-in-picture effects, and its own media players for clips and stills. The integrated Fairlight audio console offers a professional digital audio mixer with fader control, EQ, dynamics, and extensive mixing capabilities across dozens of channels, potentially eliminating the need for an external audio desk. The system includes a comprehensive built-in 16-channel multi-viewer, support for dozens of 12G-SDI and HDMI inputs (expandable via cards), and advanced features like macros, super sources, and multiviewer layouts.

Housed in a redundant 4RU rackmount chassis with dual hot-swappable power supplies and network control ports, the ATEM 4 M/E Constellation 4K is built for 24/7 mission-critical reliability. It is controlled via multiple ATEM Advanced Panels (sold separately), which provide tactile, broadcast-style control over every function. By combining extreme processing power, massive I/O flexibility, integrated broadcast audio, and fault-tolerant design, this switcher represents a complete, future-proof production ecosystem for premier sports networks, global broadcasters, and elite event production companies.
