Blackmagic Design BMD-SWATEMSCN2/2ME2/4K ATEM 2 M/E Constellation UHD 4K Live Production Switcher

Powerful Live Production Switcher for 4K Broadcast Environments

The ATEM 2 M/E Constellation 4K is a high-end live video switcher built for professional multi-camera productions. With 20 genuine 12G‑SDI inputs and 12 outputs, it offers full UHD resolution support and robust signal distribution. Whether you're directing broadcasts, live events, or studio shows, this switcher provides all the bandwidth and control you need for top-tier video workflows.

Seamless Connectivity With Multi‑Format SDI Support

Engineered to handle 12G, 3G, and HD‑SDI simultaneously, this switcher offers format-flexible compatibility across input channels. Each source supports its own frame rate and format conversion, simplifying mixed-resolution production environments and reducing the need for external converters.

High‑Definition Monitoring With Multiview Support

Featuring up to 16 multiview windows, the switcher allows simultaneous feed monitoring on a single screen. This provides operators and directors with a real-time layout of program, preview, audio meters, and camera views—enabling fast decision-making and accurate signal routing.

Advanced Audio Mixer and Keying Tools Onboard

Integrated into the switcher is a full 48‑channel audio mixer with individual controls per input, along with comprehensive mix-minus support. The system also includes 8 upstream and 2 downstream keyers, alongside chroma, luma, and pattern generators, offering total control over layering, graphics, compositing, and visual effects.

USB‑C Webcam Output for Streaming Integration

A USB‑C port outputs clean program feed as webcam video, enabling seamless connection to live streaming services or conferencing platforms without additional capture hardware. This makes it easy to integrate broadcast-level video into cloud-based workflows and content delivery systems.

Flexible Control Options for Any Production Environment

This switcher supports both physical control panels and software control on macOS or Windows systems. Operators can engage with hardware for tactile precision or use remote software control in collaborative, multi-user setups—providing workflow options for broadcast trucks, studios, or mobile set-ups.
