Exceptional features

The ATEM 4 M/E Constellation 4K features four mix banks and 40 SDI 12G inputs, with format conversion, 28 SDI 12G outputs, channels for digital visual effects, 16 keyers per chrominance, four outputs for simultaneous display of images in 16 windows each, 4 media players, communication system and USB port, which allows the device to be detected as a webcam.

Designed for large events

The ATEM 4 M/E Constellation 4K is ideal for concerts and music festivals, allowing cameras to be positioned at different points on stage for the best coverage. Even during live sporting events, the sheer number of connections, along with channels for visual effects, make it easy to create multi-layered compositions to show every detail of the action. Live broadcasts are the fastest way to produce programmes. The mixers in this line have outstanding internal graphics and a number of advanced compositors for chrominance overlays, providing everything needed for complex productions. They are also ideal for broadcasting religious ceremonies, as they not only offer the possibility of professional results, but are also easy to use, making it simple to train volunteer operators.


Professional style with mixing and effects

The ATEM 4 M/E Constellation 4K models offer the opportunity to view both programme and pre-recorded signals at the same time, in exactly the same way as broadcast mixers. In addition, both the ATEM Software Control program and the optional hardware panels allow you to switch between the two signals. In other words, it is possible to select a preamp signal on the corresponding bus to verify that it is the correct one before broadcasting it to the air. This process reduces the chances of making mistakes.

Front panel control

The control panel, built into the front of the unit, offers the opportunity to operate the mixer with ease at any time. The ATEM 4 M/E Constellation 4K models have similar features to the ATEM Mini version, making them ideal for those wishing to use more advanced equipment. The buttons are of the same quality as those used on larger panels, making them extremely reliable. They even allow you to control compositors, media and fade-to-black from the front panel. There is also a 5-pin connection, which makes it easy to use the intercom system. In addition, all mixer features can be accessed via the menus on the front panel display.


40x 12G-SDI inputs with format conversion

ATEM 4 M/E Constellation 4K features 40 independent 12G-SDI inputs, all with HD and UHD format conversion to different resolutions. This means you can convert an incoming 1080 HD signal to any other HD or UHD format, or use each of the SDI connections in a different format at the same time..

24 configurable 12G-SDI outputs

The ATEM 4 M/E Constellation 4K features 24 independent 12G-SDI outputs. The 12G outputs provide the ability to independently transmit any SDI signal, or internal source, to each of the SDI outputs, which is ideal for sending separate signals to on-stage displays, recorders, and processors for streaming over the internet. The SDI outputs can also be used to record each camera's image in isolation, with each recorder receiving a perfectly resynchronised signal from the mixer. In addition, all SDI outputs allow the integration of audio, as well as RP-188 timecode and signals for camera and Tally light control. They also facilitate communication with other crew members.

USB port for software

All ATEM Constellation 4K switchers feature a USB-C port, which allows them to be recognised as a webcam, making it easy to stream content over the internet. Simply connect any of these models to a computer and you can start broadcasting live using any of the dedicated software. This makes it possible to stream 1080p HD resolution images via platforms such as Zoom, Microsoft Teams or Skype, for professional-style presentations using multiple cameras. The USB port on these mixers also supports Open Broadcaster, XSplit Broadcaster and similar software.

Physical or virtual control panels

All Blackmagic Design ATEM switchers support a wide variety of control options and allow you to share panels between different models for different types of live events. The ATEM 4 M/E Constellation 4K includes full control software for Mac and Windows, which communicates with the switcher via Ethernet or USB and gives you the ability to operate the switcher, upload files, mix audio and control cameras. For more complex projects, we recommend connecting ATEM Camera Control Panel or ATEM Advanced Panel devices to operate the cameras with more precision or to switch between different signals, respectively. In addition, these devices feature development tools to create customised solutions.


4 Multiviewer with labels, indicators and vumeters

The simultaneous display provided by the Multiviewer's four outputs allows multiple sources to be monitored on a single monitor. The 4 M/E model has four simultaneous display outputs. In addition, all external signals and internal sources can be assigned to any of the outputs. In addition, labels and vumeters can be superimposed on the image in each window, and a red or green border can be displayed around the signal, indicating that it is on-air or a preamp, respectively.

Transitions, visual effects and more

The ATEM 4 M/E Constellation 4K mixers include a wide range of professional-quality transitions such as fades, dissolves and wipes, whose duration, position and direction can be adjusted, as well as their colour and border width. In addition, the unique digital visual effects processor allows the image to be pushed out of the screen, creating a new shot, as well as creating wipes with dynamic graphics. Moreover, in order to avoid mistakes, this range of devices offers the possibility to preview the transition to check it before broadcasting it on air.

Integrated visual effects

The ATEM 4 M/E Constellation 4K includes 4 channels of digital visual effects. This makes it possible to achieve an amazing quality of effects and to change the position and size of compositions in real time, as well as to create professional effects with simultaneous images (PIP), parallel shadows and adaptive three-dimensional borders. Moreover, these effects can be used in animated transitions, which add dynamism to broadcasts. In addition, the mixer makes it easy to combine these transitions with graphical elements to create customised wipes. The two- and four-bank versions offer SuperSource processors, while the 1M/E does not have SuperSource processors.


Professional intercom system

The ATEM Constellation includes a communication system that facilitates coordination between different members of the production. This includes a 5-pin headphone connection on the front panel and an RJ12 connection on the rear for common systems such as ClearCom and RTS. It also has channels for communicating with engineers and other team members, and allows you to control the local effect to hear your own voice, as well as mixing the programme audio. You can also communicate with Blackmagic Design cameras on SDI channels 15 and 16, and with engineers on channels 13 and 14. You can even mix the communication audio with the programme audio for live commentary.

Internal images and graphics

The ATEM 4 M/E Constellation 4K allows high-quality animations and graphics to be stored in RGBA format for instant playback. Specifically, the media players function as additional sources on the ATEM 4 M/E Constellation 4K, so there is no need for additional SDI inputs. The integrated media panel stores graphics for later use in the players. ATEM Software Control, included with the mixer, makes it easy to organise media files, but it is also possible to import them directly from Photoshop, using the ATEM Photoshop plug-in.

New chrominance compositor

The ATEM 4 M/E Constellation 4K is ideal for news bulletins or virtual sets, with 16 advanced keyers for luminance and chrominance overlays. The colour picker allows the background to be sampled for the purpose of automatically generating the mask parameters. In addition, controls for edges and reflections, as well as a colour corrector, are included for the foreground image so that its appearance matches that of the background, thus achieving a perfect composition. The compositor can also be used for masks with geometric shapes and digital visual effects, providing unparalleled versatility.

Extraordinary virtual scenery

Thanks to the 16 compositors for chrominance overlays in the mixing and effects banks, it is possible to achieve extraordinary virtual scenarios. In addition, one compositor per camera can be used to create a seamless composition on the custom background.

12G SDI connections for a range of HD and UHD formats

These switchers have 40x 12G SDI inputs, compatible with all types of HD and UHD sources. You can connect equipment in a variety of HD and UHD television formats, whether it's 720p, 1080i, 1080p or 2160p. Only this type of SDI connectivity provides the ability to switch between formats in different definitions, thus offering absolute flexibility for all types of projects. The SDI inputs also allow processing of the embedded audio, and mixing of audio from all video signals. The main outputs allow signals to be transmitted to control the camera, activate the Tally light and communicate with the operator. This means that it is possible to connect any of the SDI outputs to the camera, to get a return signal, control the unit and the intercom system.

Fairlight audio mixing

Thanks to the Fairlight tools, the ATEM Constellation allows for complex audio mixing. These mixers offer a total of 156 channels, more than any other mixer, for live productions. Audio is separated from the SDI inputs and transmitted to the audio mixer. All of these features are available via ATEM Software Control or through a compatible Mackie panel.

All features included at no additional cost

Unlike other mixers, all features are included in the retail price and are available and ready to use. There are no additional charges or monthly subscriptions. So there is no need to worry about a licence expiring just before starting a broadcast. The simultaneous display of images, the SuperSource function, digital visual effects and compositors are always activated and available to the user. In addition, ATEM Software Control can be run simultaneously on different computers. This is extremely important when dividing the work between different people involved in audio mixing, graphics preparation, camera control and mixer operation.
