Atomos AO-ATOMSUMO19 (AOATOMSUMO19, AO/ATOMSUMO19, AO ATOMSUMO19, ao-atomsumo19) Atomos Sumo 19" HDR/High Brightness Monitor Recorder

BUILT FOR PRODUCTIONThe first production monitor that also records 4K 12bit Raw, 10bit ProRes/DNxHR, plus 1080p60 live switching and recording

Rugged construction. Flexible mounting

The Aluminium alloy chassis with built-in armor houses ten mounting points around the top/bottom/side, a rear panel VESA mount and an included stand for a variety of mounting configurations. Alongside of the XLR connections for power and balanced audio, there is a 3.5mm stereo headphone jack and built-in speakers. The optional mounting plates connect dual V-Lock or Anton Bauer batteries work in tandem with our patent pending continuous power system. This allows batteries to be hot swapped to ensure you are never without power in the field.


Seamlessly connect any SDI or HDMI device and convert between HDMI 2.0 and SDI (3G QuadLink/6G/12G) in any combination. Quad SDI inputs connect cameras with multiple 1.5 or 3G SDI outputs without the need for converters. HDMI 2.0 supports up to 4Kp60 input/output along with the very latest Atomos open protocol that supports HDR automation including importing of camera settings. There is also support for Genlock and LTC timecode.

Professional Recording

12-bit Raw, 10-bit ProRes/DNxHR up to 4Kp60

Capture the RAW output from Sony FS5/FS7/FS700, Canon C300MKII/ C500 or Panasonic Varicam LT over SDI up to 12-bit 4Kp30 as CDNG or 10-bit Apple ProRes / Avid DNxHR up to 4Kp60 / 2Kp240 depending on the camera’s capability. The processing power of Sumo preserves pristine quality direct from the sensor with data rates of up to 3.2 Gbps.

Monitor. Switch. Record

Live Switch and Record up to four 1080/60p channels, 4 x ISO record and playback

Make working with multi-cam a breeze. Switch and mix a live record and stream or record 4 x HD ISO recordings using the QuadLink SDI connections. Switch between feeds on screen with cueing, cross fade and hard cuts from the locked sources or tag and adjust final edits with advanced metadata tagging preserving ISO feeds, with the desired final result infinitely editable.

XLR Monitor & Record

Balanced XLR Monitor & Record with 48V Phantom

Eliminate the need for a separate audio recorder by using the full size XLR connections to connect and power external microphones for balanced analogue audio with dedicated meters and adjustments for frame delay and gain. 48V phantom mics or line level audio are all seamlessly synchronized for the most advanced audio feature set in a monitor today. There is also a 3.5mm stereo headphone jack and built-in speakers for on set instant immersive review or complete internal recording review anytime anywhere with clients or production team.

Go HDR Today.

In the field & the studio

Sumo’s 19” 1920x1080 10-bit LCD panel is driven by the AtomHDR engine which precisely maps the Log/PQ/HLG from popular cameras, game consoles or TV makers to perfectly resolve 10+ stops of HDR in real time. The brightness range and vivid colors of HDR bring scenes to life either on the monitor itself, or when output to larger HDR/Rec709 displays for on set review. It can also be used with popular NLE or grading suites for affordable HDR or SDR editing or grading in the studio.

High Bright for REC709 Outdoor shooting

1200nit 19” calibrated 1920x1080 monitor

The extremely bright 1200nit display means you can accurately monitor, even when outside in full daylight. Additionally, for the ultimate low light performance an optional hood is available. The simplicity of AtomOS means its only a single tap on screen to bring up focus peaking, 2:1/1:1 zoom, Zebra, False Color, Frame guides, SMPTE Safe Area, Waveform, RGB parade, Vectorscope, Anamorphic desqueeze and a flexible 3D LUT implementation to upload your own LUTs as .cube files.

Trust what you see

Calibrate for accurate color

Like all high-end monitor’s, Sumo also has optional calibration to compensate for the natural color and brightness drift that monitors exhibit over time. Sumo’s calibration input lets you use X-Rite’s i1DisplayPro to always ensure accurate HDR and Rec709 monitoring.

Continuous Power

Never go without power

The optional mounting plates connect dual V-Lock or Anton Bauer batteries that work in tandem with our patent pending continuous power system. Sumo automatically swaps to the second battery when power is low, allowing the drained battery to be hot swapped to ensure you are never without power in the field
