Blackmagic Design ATEM 2 M/E Constellation 4K – 20-Input Switcher
Product Overview
The Blackmagic Design ATEM 2 M/E Constellation 4K is an advanced 2 M/E Ultra HD live production switcher with 20 standards-converted 12G-SDI inputs, 12 12G-SDI aux outputs, 8 ATEM Advanced Keyers, two multiviews, two DVEs, and a SuperSource processor for a total of 6 DVEs. It's built for demanding multi-camera live production with a built-in control panel and Fairlight audio.
Product Description
Part of the ATEM Constellation family — Blackmagic's most powerful HD and 4K live production switchers — the 2 M/E model offers 20 inputs, each with a full standards converter so mixed-format sources just work. It includes ATEM Advanced Chroma Keyers, media players, dual multiviews, and a SuperSource multi-layer processor, plus a built-in Fairlight audio mixer with a compressor, limiter, 6-band parametric EQ, and expander on every input. The free ATEM Software Control is included, and you can add a 1 M/E, 2 M/E, or 4 M/E ATEM Advanced Panel.
The compact rack-mount chassis has a built-in control panel for walk-up operation — critical during setup or emergencies — with a large LCD for program output and on-screen menus. The rear panel carries 12G-SDI inputs, aux outputs, balanced audio, and Ethernet control, and the switcher runs quietly thanks to a high-efficiency thermal system. ATEM Constellation uses professional program/preview operation, the same two-step workflow used by broadcasters, so sources are confirmed on preview before being cut to air. Front-panel access includes keyer, media, and fade-to-black control plus a 5-pin talkback headset connector.
