Advanced Broadcast Power
The Blackmagic Design ATEM 4 M/E Constellation HD switchers have a compact rack mount design and an integrated control panel. This enables switcher operation, which is critical during setup or for emergency use. A large LCD is also included, allowing you to view program output and change switcher settings via on-screen menus. The switcher's compact design is ideal for portable live production, with connections for 3G-SDI inputs, 3G-SDI aux outputs, balanced audio, and Ethernet control on the rear. The top 4 M/E model even has serial control RS-422 and MADI digital audio connections. Despite its immense power, the ATEM Constellation is extremely quiet thanks to its innovative high efficiency thermal system.

Designed for Large-Scale Live Events
Blackmagic Design ATEM 4 M/E Constellation HD switchers, which come in three powerful models, are ideal for concerts and music festivals because they allow you to place cameras in all areas of the stage for incredible coverage! Even live sports benefit from a large number of inputs, and DVEs allow you to create multi-layer compositions to cover the action. Live programming is the quickest way to create content! You get everything you need for complex program production with powerful internal graphics and a plethora of ATEM advanced chroma keyers. ATEM Constellation is also ideal for house of worship programming because it is large enough to produce professional results while remaining simple enough to train a volunteer crew!

Mix Effects in True Broadcast Style Switching
Blackmagic Design ATEM 4 M/E Constellation HD employs a professional "program/preview" mode of operation, similar to how large broadcasters employ Production Equipment, Live Production Switchers. This means you're employing the same switcher as the television industry. Program/preview style switching will be possible with both the free ATEM Software Control and the optional hardware ATEM Advanced Panels. This means you can test a source on the preview bus before switching it on air by pressing the CUT or AUTO button. This two-step program/preview process results in far fewer errors! ATEM Constellation's program/preview operation means it is the best solution for preparing students for a career in broadcast television!

Up to 40 Standards Converted 3G-SDI Inputs
The Blackmagic Design ATEM 4 M/E Constellation HD family features models that have up to 40 independent 3G-SDI inputs, with each input featuring its own dedicated up and cross converter. That means it’s possible to convert any 1080p input source to the video standard of the switcher! That means you could have each switcher SDI input running a different television standard and all the inputs will just work! On the ATEM 4 M/E Constellation HD model, you can even loop out audio channels 1, 2, 3 and 4 from SDI inputs 1 to 30 to the two MADI digital audio outputs, so you can hand off the switcher input audio to an external audio engineer for mixing.

Up to 24 3G‑SDI Outputs
The Blackmagic Design ATEM 4 M/E Constellation HD family have a massive number of fully independent 3G-SDI outputs. Even the small 1 M/E model has 6 x 3G-SDI outputs! Then the 2 M/E model has 12 x 3G-SDI outputs and the 4 M/E model has a massive 24 x 3G-SDI outputs. These SDI outputs are very powerful because you can independently route any SDI input or any internal source to each SDI output. That’s perfect for running independent feeds to stage screens, master recorders and streaming processors. Or use the SDI outputs for ISO recorders, where each deck will get a resynchronized switcher input with matching timecode. All SDI outputs contain program audio, RP-188 timecode, SDI camera control, tally and talkback.

Complete Front-Panel Control
You can walk up to the Blackmagic Design ATEM 4 M/E Constellation HD and operate it at any time thanks to a control panel built into the front panel. ATEM Constellation HD has similar features to ATEM Mini, making it an excellent upgrade when you require a larger switcher! Furthermore, the front panel control buttons are the same premium type found on full-sized panels, making them extremely reliable. From the front panel, you can even control keyers, media, and fade to black! On the front panel, there is an industry standard 5 pin talkback headset connector as well as controls for talkback control. Furthermore, almost every operational feature of the switcher can be accessed via the front panel LCD and menu buttons!

Video Software with USB Webcam Output
The USB-C connection on the Blackmagic Design ATEM 4 M/E Constellation HD serves as a webcam source to aid in live streaming. That means you can plug it into a computer and use any video software! The software thinks the Blackmagic Design ATEM 4 M/E Constellation HD is a regular webcam, but it's actually a live production switcher! This ensures complete compatibility with any video software and full resolution 1080HD quality. Choose any software you want, such as Zoom, Microsoft Teams, or Skype, for a new way to present in a professional multi-camera broadcast quality style! The Blackmagic Design ATEM 4 M/E Constellation HD webcam output is also compatible with streaming software like Open Broadcaster, XSplit Broadcaster, and others!

Choose between hardware and software control panels
All ATEM switchers have a wide range of hardware and software control options, and control panels can be shared between all ATEM models for different events. A free software-based control panel for Mac and Windows is included with Blackmagic Design ATEM 4 M/E Constellation HD. You can control the switcher, upload media, mix audio, and control cameras using the software, which connects to the switcher via Ethernet or USB. When you require additional power, you can add an ATEM Advanced Panel for professional switching or an ATEM Camera Control Panel for camera control. There's even an ATEM developer SDK available to help you create your own custom automation control solution!

Multiview with Labels, Tally, and Meters
The built-in multiview feature allows you to monitor multiple sources on a single screen. The 1 M/E model comes with one multiview, the 2 M/E model comes with two independent multiviews, and the 4 M/E model comes with four independent multiviews! Any view can be fed from any external SDI input as well as any internal video source. All multiviews are completely customizable and can be set to 4, 7, 10, 13, or 16 simultaneous views. That adds up to 32 total views on the 2 M/E model and a whopping 64 total views across 4 monitors on the 4 M/E model! On each view, you can add the tally border, source label, and VU meters as an overlay. In addition, a red and green border will show the tally on each view, letting you know which sources are on the air.
