The ATEM 1 M/E Constellation UHD 4K Live Production Switcher adds UHD 4K capabilities and 12G-SDI ports to the familiar switcher construction of its predecessor. Designed for powerful live event UHD 4K switching, the unit features 10 individual 12G-SDI inputs that support 12G/3G/HD-SDI signals and deliver them to six 12G-SDI outputs or webcam USB-C output. In addition, the switcher has a multiview output with up to 16 routable windows that can display inputs, keyed video, graphics, and stills from the media pool, as well as the program output. Each input connects to a built-in Fairlight audio mixer supporting up to 28 channels of audio.
