The ATEM 4 M/E Constellation 4K is the 40-input Ultra HD member of Blackmagic Design's Constellation switcher line. It is designed for broadcast, events and streaming teams that need a full 4 M/E workflow, 12G-SDI infrastructure and independent standards conversion on every input without moving to the larger Plus chassis.
It keeps the core creative toolset of the 4 M/E family: 4 DVEs, 16 ATEM Advanced Chroma Keyers, 4 media players, 4 Ultra HD multiviews, 2 SuperSource processors, talkback and a 156-channel Fairlight audio mixer. The 2U rack format makes it the lower-footprint alternative to the 4K Plus while retaining professional SDI routing and software or hardware panel control.
The ATEM 4 M/E Constellation 4K Plus is Blackmagic Design's high-density Ultra HD live production switcher for arenas, broadcast control rooms, houses of worship and multi-camera streaming builds. It combines 80 standards-converted 12G-SDI inputs with 48 aux outputs, four independent Ultra HD multiviews and a full 4 M/E architecture for productions that need many sources online at once.
Creative tools are built into the chassis rather than licensed separately: 4 DVEs, 16 ATEM Advanced Chroma Keyers, 4 media players, 2 SuperSource processors, front-panel emergency control, talkback and a 156-channel Fairlight audio mixer. It is a 4U rack system for professional SDI infrastructure, control panels and engineering workflows.
