Blackmagic ATEM 1 M/E Constellation 4K

This advanced Ultra HD switcher delivers exceptional performance for live productions that require speed, flexibility and uncompromising image quality. Its compact rack‑mountable form makes it ideal for portable systems while retaining the robust processing capabilities expected from modern multi‑camera workflows. With ten fully standards‑converted 12G‑SDI inputs, the system accepts a wide range of formats up to 2160p60 without the need for external converters. Each input performs real time frame rate and format conversion to ensure seamless integration of diverse sources, making it suitable for fast changing environments where content arrives from multiple devices and resolutions. 

The switcher provides six independent 12G‑SDI outputs that can serve as program, preview or auxiliary feeds. These outputs support embedded sixteen channel audio, time‑critical routing and format independent operation. Its built‑in multiview system displays up to sixteen sources simultaneously using a single Ultra HD output, with optional labels, audio meters and clean feed views. This monitoring flexibility enhances situational awareness during complex productions and allows operators to maintain full control over incoming sources, graphics and key layers without additional hardware. 

A built‑in digital video effects processor enables smooth repositioning, scaling and compositing of layers, while four advanced chroma keyers make it suitable for virtual sets, keyed graphics and live overlays. The internal architecture supports up to seven simultaneous layers, combining upstream and downstream keys with media players and masks. For productions requiring broadcast‑grade communication, integrated talkback and tally support help coordinate operators and camera crews. The system includes an internal timecode generator and direct Ethernet connectivity for linking to software or external hardware panels. A USB webcam output transforms the switcher into a direct video source for streaming platforms, allowing Ultra HD pipelines to integrate seamlessly with computer based workflows.

Audio performance is driven by a professional twenty‑eight channel Fairlight mixer that includes a full suite of dynamics processing and parametric equalisation. This integrated audio engine ensures that high quality sound accompanies the visual output and reduces dependence on external mixers. The front panel allows emergency switching with illuminated buttons and a built in display, while full control is available through the included software on Mac or Windows.
