ATEM 1 M/E Constellation HD is a high definition live production switcher packed with advanced features. The single M/E design includes 10 standards converted 3G‑SDI inputs and 6 independent 3G‑SDI aux outputs. It also includes a USB webcam output, DVE, chroma keyers, media players, multiview and more.

ATEM Constellation HD 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 the connections for 3G-SDI inputs, 3G-SDI aux outputs, balanced audio and Ethernet for control. The top 4 M/E model even includes 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.

ATEM Constellation HD 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!

The ATEM 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!

The ATEM 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! 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.

The built in multiview lets you monitor multiple sources on a single monitor. The 1 M/E model includes 1 multiview. All external SDI inputs, plus all internal video sources can be routed to any view. You can add the tally border plus source label and VU meters as an overlay on each view. Plus a red and green border will show tally on each view, so you know what sources are on air.

ATEM Constellation HD is the world’s first live production switcher that fully embraces live professional audio production! All SDI inputs are connected to a built in Fairlight audio mixer that features 6 band parametric EQ, compressor, limiter, noise gate and expander on each input. On the ATEM 4 M/E Constellation HD model there are 2 MADI outputs for breaking out channels 1, 2, 3 and 4 of the first 30 SDI inputs out to an external audio engineer, plus a MADI input for allowing an extra 32 external audio channels in to the audio mixer. The Fairlight audio mixer even has additional inputs for mixing audio from analog inputs, talkback microphones for voice over and more. A built-in Fairlight Audio Mixer also makes it possible to do complex live sound mixing.
