Key features for live production
12G-SDI and conversions on all inputs
Each input features format and frame rate conversion, allowing heterogeneous HD and Ultra HD sources to be combined without external converters. The 12 routable SDI outputs adapt to studio needs.
Advanced keying and compositing
With 8 chroma keyers, 2 DVEs, 2 Stingers, and SuperSource, you can quickly build virtual sets, picture-in-picture, and complex video walls.
Integrated monitoring and audio
Two configurable multi views provide precise control over program, preview, and sources. The 48-channel Fairlight mixer with 6-band EQ and dynamics ensures professional sound management.
Seamless integration in control rooms
USB-C webcam output for streaming software, tally, talkback network, internal timecode generator, and control via ATEM software or optional hardware panel complete a solution focused on efficiency.
