Blackmagic ATEM 4 M/E Constellation 4K Plus
The ATEM 4 M/E Constellation 4K Plus is a 5RU live production switcher with forty 12G-SDI inputs and four full mix effects rows, all running at 2160p60. It is built for the shows where an eight input switcher runs out of room on the first rehearsal, and where every source needs to stay in 4K rather than being downscaled to fit.
Each M/E carries four upstream keyers, and there are 40 keyers, 4 DVEs and 32 SuperSource layers across the unit, plus multiple downstream keyers and independent multi views. Audio is a full Fairlight mixer with EQ and dynamics on every input. Control is over Ethernet from ATEM Software Control or from any of the ATEM hardware panels.
