The Blackmagic Design ATEM 4 M/E Broadcast Studio 4K is a high-capacity, rack-mountable live production switcher engineered for large-scale, multi-camera broadcasts and events. This system integrates a massive 40-input, 4 M/E (mix/effect) video switcher, a professional 16-channel audio mixer, a frame synchronizer, and a multi-viewer processor into a single 1RU unit, delivering studio-grade production power in a remarkably compact form factor. It is designed to serve as the central hub for the most demanding live productions, such as major sports broadcasts, national news programs, and large concert events, where complex layering of graphics, video effects, and multiple camera angles is required in real-time. The switcher supports 4K Ultra HD video at up to 60 frames per second across all inputs and outputs, ensuring compatibility with modern high-resolution production workflows.

A key feature of this system is its four fully independent M/E banks, each equipped with four keyers and two DVEs, allowing technical directors to build intricate, multi-layer compositions and switch between them seamlessly. Every input includes a frame synchronizer, enabling the integration of any video source regardless of its native timing. The integrated Fairlight audio mixer provides comprehensive control over embedded SDI audio, analog XLR inputs, and USB audio from computers, with features like ducking, delay, and parametric EQ on each channel. The built-in multi-viewer can output up to four separate HD multi-view feeds, each customizable with up to 16 windows, providing different operators with their own tailored view of all sources, outputs, and scopes.

Control of the ATEM 4 M/E Broadcast Studio 4K is achieved through the included ATEM Software Control application or via hardware control panels like the ATEM Advanced Panel for a tactile broadcast console experience. The switcher includes a hardware streaming engine for dual independent stream encodes and a built-in recording engine for capturing program and clean feed outputs directly to USB media. With support for 16-channel Dante audio networking, internal media players for clips and stills, and macro automation, it represents a complete, software-defined live production studio in a single chassis. This switcher is the cornerstone for broadcasters and production companies that require uncompromising performance, reliability, and creative flexibility for their most critical live events.
