Blackmagic Design ATEM 4 M/E Constellation 4K Plus

The Blackmagic Design ATEM 4 M/E Constellation 4K Plus is the top model in Blackmagic's live production switcher line, built for large-scale broadcast, concert, and sports productions that need to manage dozens of simultaneous 4K camera feeds. It's aimed at technical directors running complex, multi-layer live shows who also need serious on-board audio mixing rather than routing sound to a separate console. With standards conversion built into every input, it accepts mixed HD and Ultra HD sources on the same switcher without external converters.

• 80 standards-converted 12G-SDI inputs: Each input includes a dedicated standards converter, so mixed HD and Ultra HD sources can run on the same switcher simultaneously.
• 48 12G-SDI aux outputs: Independently routes any input or internal source to feeds for stage screens, recorders, or streaming processors.
• 16 ATEM Advanced Chroma Keyers: Four upstream keyers per M/E row support complex virtual-set compositing with foreground color correction.
• 2 SuperSource processors: Adds four extra DVE layers plus a background layer each, functioning as a built-in multi-layer VFX switcher.
• 156-channel Fairlight audio mixer: Includes 6-band parametric EQ, compressor, limiter, and expander on every input channel.
• 4 independent Ultra HD multiviews: Each customizable to show 4, 7, 10, 13, or 16 sources at once, for up to 64 views across four monitors.
• Built-in talkback: Supports 5-pin XLR headset connections plus SDI channel-based talkback direct to Blackmagic Design cameras.
