The Atomos Sumo 19″ SE HDR monitor, recorder and switcher features an enhanced 19-inch QLED touchscreen display with 1920 x 1080 pixels and 1200 cd/m² brightness. It offers the same 4K recording, monitoring and switching features as its predecessor, but with a sharper and brighter display. Four 12G-SDI inputs and one HDMI 2.0 input can receive video signals up to 4K60 and support live four-channel switching. Five-channel recording captures both input signals and live switching to create a single output video for efficient viewing. Genlock and LTC timecode are also supported by the HDMI 2.0 and Quad-SDI connectors.

The Sumo 19″ SE can record in ProRes RAW and 8-bit+FRC 422 ProRes/DNxHR encoding formats. RAW, Log, PQ and HLG outputs from various cameras or game consoles can be processed by the device and mapped to display HDR with more than 10 stops of dynamic range in real time. This makes the Sumo 19″ SE ideal for on-site monitoring by the director or client. Two XLR inputs with +48V phantom power support balanced audio recording with external equipment. With included tabletop feet, mounting accessories, and multiple power options, you can easily integrate the Sumo 19″ SE into your studio setup.
