It is a live switcher designed for HD and UHD 4K streaming productions. Twenty 12G-SDI inputs support UHD 4K video up to 59.94 fps, and are backward compatible with 1080p, 1080i, or 720p (inputs are unscaled, so all sources must be the same resolution). All inputs are frame-synchronized, so unsynchronized sources can be used. Audio is supported through all SDI inputs plus 2 sets of dedicated analog stereo inputs through XLR and RCA. To mix on the box, connect a computer running ATEM software control and have immediate control of all audio channel inputs. Connections for time code, reference and control are also available. The SDI outputs are available for scheduling and preview, and can operate in HD or UHD resolutions, just like the inputs. Two preview outputs allow you to extend your multi-view across two screens.
Like its namesake, ATEM 4 M / E Broadcast Studio 4K features four mixing effect buses for creating advanced effects to increase production value. Within each mixing effects bus, there are 4 built-in upstream keyers, for a total of 16 keyers, allowing your production to take advantage of many layers of video and graphics simultaneously. Two rear encoders are also available for errors, logos, and global lower thirds. Built-in DVE processing allows you to adjust video footage with control over size and rotation, plus 3D edges, 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 the ATEM switch firmware to be updated in the future and for internal configuration. The entire ATEM 4 M / E Broadcast Studio 4K chassis fits within a standard 19 “equipment rack, requiring only 2 RU. Redundant internal power supplies require separately available standard IEC cables for power.
