The blackmagic ATEM 2 M/E Constellation HD switcher with 20 3G-SDI inputs is a high-definition live production switcher packed with advanced features. The dual M/E effects bank design includes 20 standard-converting 3G-SDI inputs and 12 independent 3G-SDI aux outputs. It also offers a USB webcam output, processor for SuperSource, DVE, colour keys, media player, multiview and more. It also includes a talkback function and a professional Fairlight audio mixer with EQ and dynamics. In addition, the switcher has two multiview outputs with up to 16 routable windows that can display inputs, key video, graphics and photos from the media pool, as well as programme output. Each input connects to an integrated Fairlight audio mixer that supports up to 48 audio channels. The switcher has a reference video input and each input is equipped with a frame synchroniser, frame rate converter and format converter. This makes it possible to combine cameras, formats, non-genlocked cameras and video input from computer sources. Upstream and downstream keyers and effects are supported. All this is done live and in real time, with no rendering required. You can control the Blackmagic ATEM 2 M/E Constellation HD switcher using the built-in front panel, optional Blackmagic ATEM panels or downloadable control software.
