Atomos has announced its new 19 inch Sumo production monitor that also records 4K 12bit Raw, 10bit ProRes/DNxHR, plus 1080p60 live switching and recording


Atomos says it’s the first production/studio monitor to combine a 19” HDR 1200nit 10+ stop panel with 4K 12bit Raw or 10bit 422 ProRes/DNxHR recording and HD recording up to 240p or live switching and recording of four 1080p60 channels.


“Seeing innovation come to life is the most exciting part of making technology products. Sumo is one of the most remarkable video products I have worked on.” said Jeromy Young CEO and co-founder of Atomos. “Versatile and highly advanced yet simple to use, it covers all kinds of high quality production from end to end at a fraction of traditional costs. The Atomos Sumo is truly revolutionary”.


Here are the basic specs


HDR on-set grading and editing

Sumo’s panel is driven by the AtomHDR engine which maps the Log/PQ/HLG from popular cameras. Atomos says the Sumo can also be used with NLE or grading suites for HDR or SDR editing or grading.


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

It captures 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. 


Live Switching

The Sumo can switch and mix a live record and stream or record 4 x HD ISO recordings using the QuadLink SDI connections. 


Balanced XLR Monitor and Record with 48V Phantom

The Sumo has full size XLR connections to connect and power external microphones for analogue audio with dedicated meters and adjustments for frame delay and gain. 48V phantom mics or line level audio are all synchronized. There is also a 3.5mm stereo headphone jack and built-in speakers for on set review or complete internal recording review.


High Bright 1200nit 19” calibrated 1920×1080 monitor

The Sumo has a 1200nit display and an optional hood is available. Sumo’s calibration input lets you use X-Rite’s i1DisplayPro for HDR and Rec709 monitoring. 



Sumo has HDMI 2.0 & 3G QuadLink/6G/12G SDI connections. 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 open protocol that supports HDR automation including importing of camera settings. There is also support for Genlock and LTC timecode.


Build and mounting options

The Sumo has an aluminium alloy chassis with built-in armour that houses ten mounting points around the bezel/top/bottom/side, a rear panel VESA mount and an included stand for a variety of mounting configurations. The optional mounting plates connect 2 x V-Lock / Anton Bauer batteries which in tandem with Atomos’ continuous power system allows batteries to be hot swapped. 


The Sumo’s total weight comes in at 6.2kg (13.7lb) and will launch in quarter three of this year at a price of around $2.5k
