Blackmagic Design's ATEM Constellation switchers are among the most powerful HD and 4K live production switchers available! This 2 M/E model features 20 inputs. Each SDI input is equipped with a full standards converter.
ATEM Constellation switchers are designed with a compact rack mount featuring a built-in control panel, essential for setup and emergency operations. The large LCD displays program output and allows for switcher setting adjustments via on-screen menus. Ideal for portable live production, the rear panel includes connections for 3G-SDI or 12G-SDI inputs, auxiliary outputs, balanced audio, and Ethernet for control. Despite their powerful capabilities, ATEM Constellation switchers are extremely quiet thanks to their innovative high-efficiency thermal system.
This switcher is perfect for concerts, music festivals, and live sports due to their extensive input options and DVEs, which enable the creation of multi-layer compositions to capture all the action. The ATEM 2 M/E Constellation 4K's internal graphics and advanced chroma keyers provide everything needed for complex program production. It's also ideal for house of worship programming, combining professional quality with user-friendly operation, making it easy to train volunteer crews.
