ATEM 4 M/E Constellation HD

The massive 4 M/E model doubles the features of the 2 M/E model with 40 x 3G-SDI inputs, 24 x 3G-SDI outputs, 4 DVEs, 16 ATEM Advanced Keyers, 4 multiviews and 2 SuperSource for 12 x DVEs in total.

Designed for Massive Live Events!

With 4 powerful models, ATEM Constellation switchers are ideal for concerts and music festivals because you can place cameras on all areas of the stage for amazing coverage! Even live sports benefit from the huge number of inputs and DVEs let you build multi-layer compositions to cover the action. The fastest way to produce programming is live! With powerful internal graphics and lots of ATEM advanced chroma keyers, you get everything you need for complex program production. ATEM Constellation is also perfect for house of worship programming as it’s big enough to allow professional results, but it’s very simple to learn so it’s easy to train a volunteer crew!

True Broadcast Style Mix Effects Switching

ATEM Constellation uses a professional "program/preview" style operation, which is the exact same way large broadcasters use live production switchers. This means you are using the same type of switcher used by the television industry. Both the free ATEM Software Control and the optional hardware ATEM Advanced Panels will allow program/preview style switching. This means you can select a source on the preview bus to ensure it’s correct before pushing the CUT or AUTO button to switch it on air. This 2 step program/preview process means far fewer mistakes! Program/preview operation means ATEM Constellation is the best solution for training students for a career in broadcast television!

Up to 40 Standards Converted SDI Inputs!

The ATEM Constellation family features HD models that have up to 40 independent 3G-SDI inputs as well as a 4K model with 12G-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 models, 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 Customizable SDI Outputs

The ATEM Constellation family has a massive number of fully independent outputs. Even the small 1 M/E model has 6 x 3G-SDI outputs! The 2 M/E model has 12 x 3G-SDI outputs and the 4 M/E models have either a massive 24 x 3G-SDI or 12G-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.

USB Webcam Output for Video Software

For live streaming, the USB-C connection on ATEM Constellation operates as a webcam source. That means you can plug into a computer and get working with any video software! The software is tricked into thinking the ATEM Constellation is a common webcam, but it's really a live production switcher! That guarantees full compatibility with any video software in full resolution 1080HD quality. Choose any software you like, such as Zoom, Microsoft Teams or Skype for a new way to do presentations with a professional multi camera broadcast quality style! The ATEM Constellation webcam output also works with streaming software such as Open Broadcaster, XSplit Broadcaster and more!
