ATEM 1 M/E Constellation 4K is a powerful 1 M/E Ultra HD live production switcher. It features 10 standards converted 12G-SDI inputs, 6 12G-SDI aux outputs, DVE, 4 ATEM Advanced Keyers, a 16 way multiview, media players and USB webcam output. You even get built in talkback and a professional 28 channel Fairlight audio mixer with EQ and dynamics!

Seriously Advanced Broadcast Power
ATEM Constellation switchers feature a compact rack mount design with a built in control panel. This allows operation of the switcher, critical during setup or for emergency use. Also included is a large LCD so you can see program output and change switcher settings via on screen menus. The compact design is perfect for portable live production, with the rear of the switcher including connections for 3G-SDI or 12G-SDI inputs, aux outputs, balanced audio and Ethernet for control. The top 4 M/E models even include RS-422 for serial control and MADI digital audio connections. Even with all this power, ATEM Constellation is extremely quiet with its innovative high efficiency thermal system.

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!

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!

Choose from Hardware or Software Control Panels
All ATEM switchers feature a wide range of hardware and software control options, plus it’s possible to share control panels between all ATEM models for different events. Included with ATEM Constellation is a free software based control panel for Mac and Windows. The software connects to the switcher via Ethernet or USB and you can control the switcher, upload media, mix audio and control cameras. Then, when you need more power, you can add an ATEM Advanced Panel for professional switching or an ATEM Camera Control Panel for controlling cameras. There's even an ATEM developer SDK so you can build your own custom automation control solution!

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!

Built in DVE for Video Effects
ATEM Constellation features up to 4 independent DVEs, depending on the model, that let you reposition graphics and create picture in picture compositions. You get amazing quality and the DVE supports position, resize and scale, all in real time. The DVE lets you create professional picture in picture effects with customizable 3D borders, shadows and lighting. DVEs can also be used to create amazing DVE transitions with squeeze and swoosh effects for adding excitement to your programming. You can even combine DVE transitions with custom graphics to create your own graphic wipe transitions! Then the 2 and 4 M/E models include SuperSource processors for even more DVEs!

Professional Broadcast Talkback
To keep crews working as a single creative team, ATEM Constellation features built in talkback. Talkback supports a 5 pin XLR headset connector, plus a rear mounted RJ12 connector for interfacing with industry standard talkback systems such as ClearCom or RTS. You get full talkback control including program and engineering loops, sidetone control for hearing the headset mic into the headphones and program mix. ATEM Constellation also supports SDI talkback that uses SDI channels 15 and 16 for 2-way communication with Blackmagic Design cameras. You can even use channels 13 and 14 for engineering talkback. It’s even possible to mix the talkback mic into the program audio for voiceovers!

Internal Media for Stills and Motion Graphics
The built in media pool stores broadcast quality RGBA graphics and animations that can be played back instantly by the 2 or 4 media players. Media players simply appear as additional input sources on the ATEM Constellation, so you don’t have to use extra SDI inputs for graphics. The built in media pool holds graphics for use with the media players and the 1 M/E models can hold 20 stills and 200 frame animations, the 2 M/E models can hold 40 stills and 400 frame animations and the 4 M/E models can hold 60 stills and up to 400 frame animations. You can easily manage all of your media using the included ATEM Software Control or download directly from Photoshop using the ATEM Photoshop plug-in.

Professional Fairlight Audio Mixer
With a built in Fairlight audio mixer, the ATEM Constellation makes it possible to do extremely complex live sound mixing. The internal mixer has up to 156 input channels, for the biggest audio mixer in a live production switcher! Audio is de-embedded from all the SDI video inputs and passed to the audio mixer. Then the 4 M/E models have extra audio mixer input channels for the MADI audio inputs. Each input channel features the highest quality 6 band parametric EQ and compressor, limiter, expander and noise gate as well as full panning. All this audio power can be controlled via the ATEM Software Control or a Mackie compatible panel.

New ATEM Advanced Keyer
Compose amazing multi layer live action
Layer live video, titles, graphics and animation over live video or graphic backgrounds with incredible quality using chroma, luma, linear and pattern keying. All ATEM live production switchers include powerful upstream keying for amazing broadcast effects! ATEM Constellation has 4 ATEM Advanced Keyers on each M/E row! On the 4 M/E models, that’s a massive 16 independent chroma keyers which means you can create mind blowing broadcast quality multi layer effects for your production.

Built‑in Multiviews
Monitor all your sources on a single monitor with labels, tally and audio meters!
ATEM live production switchers let you connect loads of sources and monitor them all at the same time using the built in multi view. Multiview makes it easy to see your cameras, graphics, preview and program outputs on a single screen. Depending on the model the ATEM Constellations feature up to 4 independent multiview outputs, that can each be individually customized or transformed into a single full resolution multiview. Each multiview can be independently set to 4, 7, 10, 13 or 16 simultaneous views. Each view also has on screen status including a custom label, VU meters and tally.

Internal Media Players
Load on-air graphics to eliminate complex external servers!
You can store broadcast quality RGBA graphics in the media pool ready for instant playback via the ATEM media players. The media players appear as input sources to your switcher. You can transition to graphics as full frame video or feed them to the keyers for overlaying video. Popular image formats such as PNG, TGA, BMP, GIF, JPEG and TIFF are supported. The advanced 4 M/E models can hold up to 60 stills and up to 3200 frame animations.
