Blackmagic Design ATEM 4 M/E Constellation 4K Switcher

The Blackmagic Design ATEM 4 M/E Constellation 4K is a powerful live production switcher designed for professional 4K workflows. It features 40 standards converted 12G-SDI inputs, giving you total flexibility with any camera or video source. Every input includes frame sync and format conversion, so mixing different formats is fast and easy. With 24 12G-SDI aux outputs, you can send clean feeds to screens, recorders, and encoders. The switcher also includes 4 Ultra HD multiviews, 4 digital video effects processors (DVEs), and 2 SuperSource processors, letting you build layered, professional content in real time.

Built for high-end production, the Blackmagic ATEM 4 M/E Constellation 4K includes a 156-channel Fairlight audio mixer. This mixer supports analog, MADI, and embedded SDI audio. You get full EQ, compressor, limiter, and gate on each input, along with parametric control and mix-minus support. This makes it ideal for live concerts, sporting events, and multi-source broadcasts. Audio is processed in real time, and the mixer is fully integrated with the ATEM control software.

Designed for mission-critical events, the Blackmagic ATEM Constellation includes a full front panel with control buttons, a menu knob, and a built-in LCD screen for real-time monitoring. You can operate the switcher directly without a control panel, perfect for setup, backup, or emergencies. The panel also has talkback controls and a 5-pin headset input for crew communication.

You can run up to 64 multiview windows across 4 Ultra HD outputs. Each window can display any input, including cameras, media players, or keyers. You can turn on tally indicators, audio meters, and source labels for easier live control. The multiview feature works in either HD or Ultra HD, giving you flexibility depending on your monitor setup.

The ATEM 4 M/E Constellation 4K includes 16 ATEM Advanced Chroma Keyers, which make virtual sets, news effects, and green screen work simple and clean. Each keyer features auto color sampling, edge adjustment, and a foreground corrector for better matching. You can even key in pattern or luma modes. These advanced keyers make this switcher perfect for streaming studios, churches, and training rooms.

Each DVE gives you smooth picture-in-picture effects, repositioning, and graphic transitions. You can add shadows, borders, and 3D effects in real time. Combine that with the two SuperSource processors, and you get multi-box layouts with custom backgrounds—ideal for interviews or panel shows. These tools help you add production value without extra hardware.

This Blackmagic ATEM Constellation also supports USB-C webcam output, so it works seamlessly with Zoom, Microsoft Teams, OBS, or any software that recognizes a webcam. This feature makes it easy to stream professional multi-cam productions from your computer. Just plug and go.

You also get 4 media players, each with fill and key outputs. The media pool holds up to 64 stills and 4 motion clips in formats like PNG, TGA, and TIFF. Add logos, lower-thirds, or transitions without giving up input sources.

On the back panel, you’ll find SDI inputs and outputs, analog audio jacks, MADI I/O, Ethernet, RS-422 serial ports, and a USB-C port for updates and configuration. The redundant power supplies and rack-mount 2U design make it ready for mobile trucks, control rooms, or flypacks.

The Blackmagic Design ATEM 4 M/E Constellation 4K is not just big—it’s smart, flexible, and made for professionals. Whether you're producing a live concert, streaming a virtual conference, or broadcasting from a house of worship, this switcher gives you top-tier tools at your fingertips.
