ATEM 4 M/E Constellation 4K
Massive 4 M/E Ultra HD live production switcher with 40 standards converted 12G‑SDI inputs, 24 12G-SDI aux outputs, 16 ATEM Advanced Keyers, 4 multiviews and 2 SuperSource for a total of 12 DVEs.

Introducing ATEM Constellation, the world’s most powerful HD and 4K live production switchers! These incredibly powerful switchers are available in 1 M/E models with 10 inputs, 2 M/E models with 20 inputs and massive 4 M/E models with 40 inputs! Plus each SDI input features a full standards converter! ATEM Constellation includes advanced features such as DVEs, ATEM advanced chroma keyers, media players, multiviews, and SuperSource processors! Plus the built in Fairlight audio mixer includes a compressor, limiter, 6 band parametric EQ and expander on each input. The free ATEM Software Control is included, or you can add a 1 M/E, 2 M/E or 4 M/E ATEM Advanced Panel!

Designed for Massive Live Events!
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!

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 4K models 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 models have 6 outputs! The 2 M/E models have 12 outputs and the 4 M/E models have a massive 24 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.

Broadcast Transitions, DVE, Stingers and More!
ATEM Constellation includes a wide range of broadcast quality native transitions such as mix, dip, wipe, and more. All transitions can be customized in the system control menus with adjustments for border color, border width, position, direction and a lot more! The ATEM Constellation switcher includes a powerful digital video effects processor for DVE transitions, which can be used to squeeze the current picture off screen revealing a new video under it. The DVE can even be used to create graphic wipe transitions. To eliminate errors, ATEM Constellation features a preview transition feature so you can setup your transitions before you switch it on air!
