Blackmagic ATEM 4 M/E Broadcast Studio 4K

  • Live switcher for HD & UHD 4K
  • 12G-SDI inputs
  • Supporting UHD 4K video
  • Compatible with 1080p, 1080i, or 720p sources




Audio is supported via all of the SDI inputs, plus 2 sets of dedicated analog stereo inputs via XLR and RCA. For in-the-box mixing, connect a computer running ATEM software control, and have immediate control of all audio channel inputs. Connections for timecode, reference, and control are also available. SDI outputs are available for program and preview, and they can operate at either HD or UHD resolutions, just like the inputs. Two preview outputs allow you to spread your multi-view over two displays.


Like its namesake, the ATEM 4 M/E Broadcast Studio 4K features four mix-effects buses for creating advanced effects to boost production value. Within each mix-effects bus, there are 4 built-in upstream keyers, for a total of 16 keyers, enabling your production to take advantage of many video and graphics layers simultaneously. Two downstream keyers for bugs, logos, and global lower-thirds are also available. The built-in DVE processing lets you adjust video streams with control over size and rotation, plus, 3D borders, drop shadows, and lighting effects are also available.


Other connectivity includes Ethernet for adding control surfaces, or for remote control over a network. USB connectivity allows for the ATEM switcher’s firmware to be updated in the future, and for internal settings. The entire chassis of the ATEM 4 M/E Broadcast Studio 4K fits inside a standard 19″ equipment rack, only requiring 2 RU of space. Internal redundant power supplies require separately available standard IEC cables for power.
