The Blackmagic Design ATEM 2 M/E Constellation HD is a comprehensive 20-input, 12-output 3G-SDI video switcher designed for professional broadcast and livestream production. It features a built-in 48-channel Fairlight audio mixer with dynamics and 6-band EQ per channel, integrated talkback with 5-pin XLR and RJ12 connectivity, and a hardware streaming engine for direct output over Ethernet or USB-C. Advanced production tools include 8 chroma keyers, a SuperSource multi-layer processor with 4 DVE layers, and a media pool for storing graphics and stills, all controllable via the front panel or the ATEM Software Control app.
This switcher employs a professional program/preview workflow, ensuring clean transitions and mistake-free broadcasts, while automatic standard conversion on each 3G-SDI input simplifies multi-format productions.
