The Blackmagic Design ATEM SDI Pro is a live production switcher designed for use with up to four converted SDI inputs. It features two SDI outputs as well as a USB webcam output - so you can use it with computer applications. A Fairlight audio mixer gives you high-quality sound with options for EQ and Dynamic - and there are two additional microphone inputs - ideal for interviews. This Pro model features a built-in streaming engine allowing you to directly stream your broadcasts to popular streaming services via an ethernet connection. It also allows for instant recording by connecting a USB flash drive so you can save streams for future offline use. And you can do this anywhere with tethering available to 5G or 4G phones for streaming on the go. The ATEM SDI Pro is designed for ease of use with four numbered source selectors and at-hand controls for changing transition types and other visual features. It offers a range of different advanced features too including DVE for picture-in-picture transition effects green screen chroma key and a collection of 20 stills media pool. Included is a free ATEM Software Control download offering even deeper control and configuration from your computer.
