Atomos Sumo 19" SE HDR Monitor, Recorder, and Switcher

The Atomos Sumo 19" SE retains the 4K recording, monitoring, and switching capabilities of the previous generation while upgrading to a sharper 19" QLED touchscreen with 2000 cd/m² brightness. It supports four 12G-SDI inputs and one HDMI 2.0 input for signals up to 4K60, plus live Quad-HD switching and five-channel recording (four ISO channels + the live program). Genlock and LTC timecode are supported over HDMI and SDI for easy integration into broadcast pipelines.

The unit records in ProRes RAW and 10-bit 4:2:2 ProRes/DNxHR, and processes RAW/Log/HLG/PQ outputs from cameras or game consoles to display 10+ stops of HDR dynamic range in real time—ideal for director/client monitoring on set. Two full-size XLR inputs with +48V phantom power deliver balanced audio capture with per-channel meters, gain, and frame-delay controls.
