?Constellation? Power in a 1U Chassis
The logical successor to the historic ATEM 1 M/E models, the ATEM 1 M/E Constellation 4K embodies the ?Constellation? range philosophy: 12G?SDI connectivity on all inputs/outputs, native Ultra HD processing, extended multiview, and modern workflows. Compared to previous generations, you benefit from conversion on every input, a direct USB?C webcam output, and a more powerful chroma key engine, all in a compact 1U form factor.
Who and What For?
Ideal for mobile production trucks, corporate studios, houses of worship, e-sports, education, or small TV stations, this 1 M/E switcher delivers professional 4K switching without complexity. Its USB?C webcam output simplifies streaming, while its 6 routable 12G?SDI outputs and 16-view multiview streamline live production on agile shoots.
Key Features for 4K Live Production
Video and Keying
The 10 12G?SDI inputs auto-detect formats from 720p to 2160p60 and synchronize with conversion. The M/E engine includes 4 advanced chroma keyers for green screen studios, 1 DVE for image effects, and a Stinger for broadcast transitions. Pattern and color generators speed up graphic setups.
Monitoring and Control
The configurable multiview (4 to 16 windows) displays labels, VU meters, and key/fill states. The front panel features a 2.2-inch LCD screen and emergency switching, while the Ethernet connection allows software control or via ATEM hardware panels.
Integrated Fairlight Audio
The 28-channel mixer manages SDI audio and analog sources with a 6-band parametric EQ, compressor, gate, expander, and limiter. The ?Audio-Follow-Video? mode ensures consistent audio/video transitions.
Simplified Streaming
The USB?C webcam output exposes the program at 720p or 1080p to streaming applications as a UVC camera, enabling immediate on-air broadcasting.
