ATEM SDI is a family of live production switchers designed for broadcasters who need extreme portability! ATEM SDI switchers are very similar to ATEM Mini, however the video connections are 3G-SDI and each model has double the number of video outputs! The USB works as a webcam for connecting video to computers. For audio the Fairlight mixer includes a compressor, limiter and 6 band parametric EQ on each input! ATEM SDI is fast to set up and easy to use. It includes 4 standards converted SDI inputs, USB webcam, 2 SDI outputs, Fairlight audio mixer with EQ and dynamics, DVE for picture in picture, transition effects, green screen chroma key, 20 stills media pool for titles and free ATEM Software Control.
