The Blackmagic Design ATEM 2 M/E Constellation HD is a large-scale professional live production switcher designed for high-end broadcast, major live events, and complex studio productions requiring multiple layers of video mixing and effects. As part of the Constellation series, it offers two independent Mix Effects (M/E) banks, each functioning as a complete production switcher with its own keyers, transitions, and upstream flexibility. This architecture allows directors to build layered compositions, perform advanced transitions between M/E banks, and manage complex graphics, virtual sets, and live feeds simultaneously.

The switcher is renowned for its extensive input capacity and processing power, supporting numerous SDI and HDMI sources in HD resolutions. Each M/E bank includes multiple keyers for graphics and chroma keying, a dedicated Media Pool for storing and playing back stills and clips, and a full Digital Video Effects (DVE) system for transformations like picture-in-picture and splitscreen. It integrates a professional Fairlight audio mixer with dozens of channels, offering EQ, dynamics, and mixing capabilities that rival standalone audio consoles. Control is managed through dedicated hardware control panels or software, with full redundancy options for mission-critical broadcasts.

Housed in a robust 2RU rackmount chassis, the ATEM Constellation HD is built for 24/7 reliability in broadcast facilities and mobile production trucks. It features redundant power supplies, dual control network ports, and a built-in multiviewer output for monitoring all sources and outputs. By combining massive processing resources, a flexible dual M/E design, and integrated broadcast audio, this switcher provides a comprehensive, scalable solution for the most demanding live television and event production workflows.
