Blackmagic Design ATEM 4 M/E Broadcast Studio 4K. The Blackmagic Design ATEM 4 M/E Broadcast Studio 4K is a live switcher designed for HD and UHD 4K broadcast productions. Twenty 12G-SDI inputs support UHD 4K video up to 59.94 fps, and are backward compatible with 1080p, 1080i, or 720p sources as well (inputs do not feature scaling, so all sources must be of the same resolution).

All inputs are frame synchronized, so non-genlocked sources can be used. Audio is supported via all SDI inputs plus 2 sets of dedicated analog stereo inputs via XLR and RCA.
