Blackmagic Design ATEM 4 M/E Constellation 4K
The Blackmagic Design ATEM 4 M/E Constellation 4K is a high-density, 2RU rackmount live production switcher designed for the most demanding Ultra HD broadcasts. While it shares many physical characteristics with the flagship 8K model, it is optimized for a pure 12G-SDI 4K workflow, offering a massive amount of I/O and internal processing power.
Core Functionality
-
40 Standards-Converted 12G-SDI Inputs: Every input features its own dedicated up, down, and cross converter. You can plug in a mix of 720p, 1080p, and 2160p sources at various frame rates, and the switcher will automatically normalize them to match your project's global standard.
-
24 Independent 12G-SDI Aux Outputs: These "smart" outputs are fully assignable. You can route any internal source (cameras, media players, or clean feeds) to any output, which is essential for complex stadium displays, multiple recorders, or diverse program returns.
-
4 Independent Multiviews: Features four 12G-SDI multiview outputs. Each can be customized to show 4, 7, 10, 13, or 16 views, allowing you to monitor up to 64 total views across four monitors simultaneously.
-
Webcam Output: Includes a USB-C port that the computer sees as a standard webcam. This allows you to use your full 40-camera broadcast setup for high-end streaming via Zoom, OBS, or Microsoft Teams at 1080p.
Internal Processing & Keying
-
16 ATEM Advanced Keyers: Each of the 4 M/E rows features 4 high-end chroma keyers. This allows for massive multi-layered compositions or complex virtual sets with multiple green-screen layers.
-
2 Independent SuperSource Processors: These are essentially "switchers within the switcher." They allow you to create complex multi-box layouts (e.g., a 4-person panel interview over a background) without using up your main M/E banks or DVEs.
-
156-Channel Fairlight Audio Mixer: A massive internal digital mixer that supports EQ, dynamics, and noise gating on every SDI input. It also features MADI inputs and outputs for expanding your audio setup to external consoles.

| DVEs | 4 independent 4K DVEs |
| Media Pool | 60 Stills + 400 Frame UHD Clip Storage |

| Power | 2 x Internal 100-240V AC (Redundant) |
Operational Insight
In a 2026 production environment, the 4 M/E Constellation 4K is the "Goldilocks" choice for large-scale Ultra HD work. It offers the same 40-input density as the 8K model but at a lower price point and with a streamlined 4K-focused firmware that boots twice as fast as legacy models.
The front panel features a full set of control buttons and a built-in LCD, which is a lifesaver for "emergency switching" or initial setup if your network connection to the control room is lost.
Expert Note on Audio: This unit features a dedicated MADI input that can bring in 32 additional digital audio channels. This allows you to link an ATEM Microphone Converter or a professional audio desk directly into the switcher’s digital fabric with zero latency.
