Blackmagic ATEM 2 M/E Constellation 4K
The ATEM 2 M/E Constellation 4K is a 2 M/E Ultra HD live production switcher built for larger multi-camera shows. It brings in 20 12G-SDI inputs, each with its own standards converter so any camera or source can be reconciled to the switcher's format, and sends out 12 12G-SDI aux outputs. Eight ATEM Advanced Keyers, two multiviews and a SuperSource push the total DVE count to six, giving an operator room for picture-in-picture layouts, chroma keying and complex graphics on a single production.
Audio is handled by a built-in 48 channel Fairlight mixer with EQ and dynamics, and there is talkback plus media players and a USB webcam output on board. Tri-Sync or Black Burst reference is available on all 20 inputs, and Ethernet control runs over 10/100/1000 BASE-T. It pairs with the optional ATEM 2 M/E Advanced Panel 20 and ships as Blackmagic part number BMD-SWATEMSCN2/2ME2/4K.
