Contents Safety Instructions
User Manual Conventions
The Sumo19 is designed to a high standard but there are some things
you should be aware of to prolong the life of the unit and for your own
safety.
Using the Sumo19 safely
Although the Sumo19 is very lightweight compared to all the devices it
replaces, it is still a solid object that could cause injury if misused.
• Always make sure that the Sumo19 is mounted securely and is unable
to fall onto anyone nearby. This is especially important when there are
children present who might be tempted to pull on cables.
• Always ensure that cable runs to the Sumo19 are clearly visible and do
not present a trip hazard.
• Do not place on uneven or unstable surfaces.
• Do not insert anything but Sumo19 Master Disk caddies in the Master
Disk slot on the side of the Sumo19.
• Do not touch the Sumo19’s screen with sharp, metallic or abrasive objects.
• Donotexposetostrongelectricalormagneticelds.
• Do not expose to or use near liquids, rain or moisture.
• Do not dispose of the Sumo19 in municipal waste and do not incinerate it,
always follow local regulations for safe disposal.
Care of disk drives
Spinning disks and SSDs are very sensitive to damage from static electricity.
Please observe all the usual ESD precautions when handling them.
Please see the section Mechanical shock and vibration later in this manual
for information about how to handle and care for your disk drives.
SDI Cables
Please remember that SDI cables use locking connectors and will not
simply pull out if they are jerked or tripped over. They are therefore a
signicanttriphazardtoyourequipment,whichmaybedamagedifthe

What you also need
Widelyavailable2.5”drivesarethebasicstoragemediumfor4KMonitor
recorder. We work closely with all the leading drive manufacturers to
qualify as many options as possible. Hard drives / HDD or Spinning disk
can only be used for HD recording. Solid State Drives / SSD are required
for4Krecordingorformoredemandingproductionenvironmentsthatmay
not be suited to HDDs.
See the section below about when you should consider using SSDs.
Which drives should you use?
There are so many drives available, and newer models appear all the
time. We are not able to test all drives but here are some guidelines.
Spinning Disk Drives (HDD) are recommended for recording up to
1080p30/1080i60 HD video only
Solid State Drives (SSDs) are recommended for recording up to
4KUHDp30and4KDCIp30fromRAW
Speed and reliability are the main factors. Here are a few things to
bear in mind:
• Disk drive data rates tend to be given in megabytes per second,
and codec data rates are normally given in megabits per second.
It’s very easy to get confused. But there’s no need to be, because all
you have to do to convert megabits to megabytes is divide by 8. So if
you’re recording at 220 megabits per second, that’s going to result in
220/8 megabytes per second, which is 27.5 megabytes per second.
• We recommend at least 7200 RPM drives. Just remember that the
higher the bit-rate of the codec you’re using, the faster the drive
needstobe,with4Krecordingyourdatarateisfourtimesfromthat
of HD recording, please ensure your drive is capable of keeping up
with4Kwritespeedrequirements.
Atomos regularly test hard drives – please check this link before
purchasing drives: http://www.atomos.com/drives
MechanicalShockandVibrationforSpinningDiskHDD’s
Hard disks are precision mechanical devices that need to be handled
carefully. The use of mechanical drives or Solid State drives will vary
dependingontheintendedlmingapplication.
We can’t give rigid guidelines because there are so many different kinds
ofdrives,eachwhichhasdifferentmechanicalproperties.Youmaynd
variations between drives of the same type.
What we have found is that mechanical drives are suitable for most
purposes that don’t involve harsh vibration or mechanical shocks. We
would not advise using mechanical disks if there is a likelihood that they
might be dropped onto a hard surface.
Here are some things that you should bear in mind when using
spinning disks:
• Even though spinning drives can withstand substantial shocks
when they are not in use, they are more vulnerable when running.
Harsh treatment that may not actually damage the drive may interrupt
recordings at a much lower level of severity. We recommend that you
experiment with your drives by testing them in the conditions that you
normally work in.
• Do not bang or jolt the Sumo19 while recording.
•Donotusespinningdrives(HDD)forrecording4Kvideo
• Youwillndnoticeabledifferencesintheabilityofdrivestowithstand
shock and to continue recording during vibration and movement.

What you also need
File Recovery
• Your Sumo19 is able to detect when the drive is under stress and it
will recover from any break in a recording by waiting until the drive is
ready to continue, and then resuming from that point. If frames have
beendroppedbecauseofshockorvibration,a“Skippy”Kangaroo
symbol will appear on the home screen on the Sumo19, in the top
left hand corner of the display. This means that you will not normally
have to restart the Sumo19, even if a recording has been interrupted
by mechanical disruption to the disk drive. (see Monitoring and
Recording : Anti-shock technology for more information)
Taking into account most usage scenarios, we think that mechanical
disks will be suitable in the majority of cases when recording up to
1080p30 HD. Spinning disks are most sensitive when they are rotating.
It is obviously best to avoid dropping them but many disks now have a
“dropdetector”thatwilllockthemostfragilemechanicalpartsinplace
and protect them from surprisingly hard knocks. We recommend that
if you want to experiment with this, you do so with a drive that doesn’t
contain the day’s shoot!
Backing up and archiving
Remember that no storage medium, including tape, optical disks, spinning
disksandashmemory,iscompletelyimmunefromfailure.
You should bear this in mind when deciding how to manage your recorded
content. At the very least, you should consider the consequences for you
and your business if your storage medium were to suffer from a sudden
failure, and you should back up your content accordingly. Hard drives
that you can use for archiving are becoming increasingly affordable. You
mayndthatitiscompletelyfeasibleforyourtokeepyourmasterSumo19
disks on a shelf (just like tapes!), and, as a backup, store copies on large
hard drives, RAID arrays, Network Attached Storage (NAS) or LTO.
4K SDI cables (not included)
SDI cables are robust physically and electrically: you should rarely have
problems with signal transmission unless your cables are either damaged
or too long. Please remember that SDI cables use locking connectors and
will not simply pull out if they are jerked or tripped over. They are therefore
asignicanttriphazard,andalsoahazardtoyourequipment,whichmay
be damaged if the cables are mishandled or of a low grade. Please ensure

HDMI cables (not included)
HDMI cables are robust physically and electrically: you should rarely
have problems with signal transmission unless your cables are either
damaged or too long.
Atomos make a range of Professional HDMI cables which are ideal for
connecting between your camera and Atomos device.
Not all HDMI cables are created equal and there are a variety of different
qualities available. Please make sure you test your cables prior to
shooting.
Also check your connectivity at both the camera connector and the
recorder/monitorconnectortomakesureyouhavearmconnectionto
avoid any signal drop out.
If the SDI / HDMI cable is removed while recording the “Skippy”
image will also be displayed. To remove touch Skippy and he will
disappear ready for his next notication.

3. Mounting disks in the Master Caddy II
Mounting drives in the Master Caddy II
Insert the disk into the caddy, and secure with four screws. The caddy is
light and the disk just needs to be held securely. Don’t over-tighten the
screws. There are no connections to make because sliding the caddy
into the Sumo19 or the Docking station makes all the connections for you.
The Master Caddy can’t be inserted the wrong way round. Always make
sure that the disk connector faces the slot in the Sumo19. You have to be

Spinning disks and SSDs are very sensitive to damage from
static electricity. Please observe all the usual precautions
when handling them, especially DO NOT EVER touch the exposed
SATA connector as static electricity may be harmful
to your disk.
Master Caddy II drives are backwards compatible with previous
Atomos recorders, however Master Caddy 1 is not forward
compatible with the Sumo19 due to the compact latch design.

Battery Options
The Sumo19 can be powered by V-Lock / Anton Bauer batteries via the
XLR terminal (optional mounting plates available). Like all batteries, you
will need to take care of them. Make sure that you don’t short circuit the
connections because this can result in very high currents that can damage
thecellsandcouldposearehazard.
Charge new batteries before using them, using the battery charger
supplied by the manufacturer.
Before any type of disposal the battery should be discharged
completely. Tape the contacts with electrical tape and package so as
to prevent contacts accidentally coming together at any time.
Incineration must be performed by an approved and permitted waste
treatment facility that handles lithium ion batteries. If you are not sure
if your waste facility can handle lithium ion batteries, contact them and
verify if they are permitted or not.
DC Power
Once the Sumo19 is switched on, it will operate from your external
DC power source if available, if no DC power source is present, then the
battery will become the primary power source if it connected by the
XLR terminal. The battery will work as redundant power if DC power is
disconnected.
Continuous Power
The Sumo19 features an Atomos technology called Continuous Power
which uses battery looping technology for uninterrupted switching
between power sources during use.
The Sumo19 may be powered from NiMH & Li Ion 14.4V battery
systems via the XLR terminal for V-Lock / Anton Bauer batteries.

4. Synchronization
Located with the SDI input and output is another BNC connector marked
Genlock:Genlockisshortfor“GeneratorLock”invideosystems.The
Genlock is an input only and will lock the internal timing system in a video
device to an external reference signal during play back.
The Genlock BNC can also be used as a LTC Timecode input. This
allows for external LTC timecode to be used enabling multiple devices to
be sharing the same master timecode signal, which makes it perfect for
multi-camera setups. LTC is only available in Record mode and can be
accessed via the Time code menu
HDMI and SDI
Built in to the Sumo19 are are both SDI and HDMI conversion. This means
that either input is able to be routed out of both the HDMI and SDI outputs
at the same time. This allows you to use SDI cameras with other HDMI
equipment or HDMI cameras in an SDI infrastructure. To toggle between
SDI and HDMI inputs access the Input Menu (page 19).

6. Master Caddy II, Screw Mounts and Sun Hood cont.
Attaching the Sun Hood
ForHDR,theviewingexperiencecaneasilybeinuencedbythe
environmental conditions and the best experience for viewing HDR
requires that you minimise the ambient light between your eyes and the
screen to easily resolve the dynamic range of the scene.
For this reason, we have developed an optional sun hood for Sumo. It
consists of a zippered corner construction that allows the user to collapse
and use as screen protection during transportation and securely screws
to the front face of Sumo to provide shelter for privacy and premium
outdoor monitoring.
To assemble the sun hood please follow the following steps:
Attach the base to the Sumo19 in the orientation shown above.
This is a snug t in order to minimize external light bleed.
Push the sunhood in, align the top and bottom screw mounting holes and
attach the retaining screws.
As the retaining screws provide anchor point for mounting make sure
they are rmly connected to provide a solid base.
With the Sun hood base in place, take the main section and pop this out
to form a rectangular tunnel and zip up the sides to ensure it looks like
the image above.
