Blackmagic ATEM 4 ME Constellation 4K Plus
The Blackmagic Design ATEM 4 M/E Constellation 4K Plus is a high‑performance Ultra HD live production switcher engineered for professional broadcasters and live event producers. Featuring four mix‑effects rows, 80 standards‑converted 12G‑SDI inputs with frame synchronizers, and support for SD, HD, and 2160p60 Ultra HD formats, it seamlessly integrates diverse camera sources in real time. Housed in a 4 RU rack‑mount chassis, it includes four independent Digital Video Effects engines for dynamic transitions, real‑time keying, and multi‑layer compositing. Its 10‑bit 4:2:2 color processing ensures broadcast‑quality color fidelity across every feed.
Output flexibility is unmatched with 48 independent 12G‑SDI aux outputs and 52 total video output channels—including USB‑C webcam streaming at 1080p/720p—and four configurable Ultra HD multiview outputs, each capable of displaying up to 16 routable windows. Two built‑in SuperSource processors add eight additional DVEs plus a background layer, empowering advanced picture‑in‑picture layouts and virtual set creations. The integrated media pool holds up to 60 broadcast‑quality stills and 1,200 frame‑based animations, instantly accessible through four media players for graphics, logos, and lower thirds. Customizable aux feeds simplify multi‑language broadcasting and large‑venue screen routing.
Comprehensive audio and keying capabilities are built in, with a Fairlight audio mixer delivering up to 298 channels of processing, two MADI inputs, four MADI outputs, balanced analog I/O, and SDI de‑embedding/embedding. Sixteen ATEM Advanced Chroma Keyers (four per M/E) provide professional green screen and luminance keying with precise controls for edge, flare, and foreground color correction. Four downstream keyers and built‑in pattern generators expand creative options for overlays, custom wipes, and sophisticated multi‑layer effects. Talkback functionality via XLR, RJ12, and SDI channels ensures seamless communication between directors, vision mixers, and camera crews.
Control and integration are streamlined through the free ATEM Software Control for Mac/Windows or optional ATEM Advanced Panels, offering tactile pushbutton switching, joystick‑based DVE manipulation, and on‑screen parameter editing via a built‑in LCD. Connectivity includes a reference input for genlock, RJ45 Ethernet for network control, RS‑422 serial, and dual IEC C14 power inputs for redundancy. An efficient thermal design guarantees whisper‑quiet operation under heavy loads, while the rugged chassis and 1‑year manufacturer’s warranty provide confidence for mission‑critical live productions. The ATEM 4 M/E Constellation 4K Plus sets the standard for scalable, broadcast‑grade 4K live production solutions.
