IMPORTANT NOTES
Power Supply
¹Do not connect this unit to same electrical
outlet that is being used by an electrical
appliance that is controlled by an
inverter or a motor (such as a refrigerator,
washing machine, microwave oven, or
air conditioner). Depending on the way
in which the electrical appliance is used,
power supply noise may cause this unit
to malfunction or may produce audible
noise. If it is not practical to use a separate
electrical outlet, connect a power supply
noise lter between this unit and the
electrical outlet.
Placement
¹Using the unit near power ampliers (or
other equipment containing large power
transformers) may induce hum. To alleviate
the problem, change the orientation of
this unit; or move it farther away from the
source of interference.
¹This unit may interfere with radio and
television reception. Do not use this unit in
the vicinity of such receivers.
¹Noise may be produced if wireless
communications devices, such as cell
phones, are operated in the vicinity of this
unit. Such noise could occur when receiving
or initiating a call, or while conversing.
Should you experience such problems, you
should relocate such wireless devices so
they are at a greater distance from this unit,
or switch them o.
¹When moved from one location to
another where the temperature and/or
humidity is very dierent, water droplets
(condensation) may form inside the unit.
Damage or malfunction may result if you
attempt to use the unit in this condition.
Therefore, before using the unit, you must
allow it to stand for several hours, until the
condensation has completely evaporated.
¹Depending on the material and
temperature of the surface on which you
place the unit, its rubber feet may discolor
or mar the surface.
¹Do not place containers or anything else
containing liquid on top of this unit. Also,
whenever any liquid has been spilled on
the surface of this unit, be sure to promptly
wipe it away using a soft, dry cloth.
Repairs and Data
¹Before sending the unit away for repairs, be
sure to make a backup of the data stored
within it; or you may prefer to write down
the needed information. Although we will
do our utmost to preserve the data stored
in your unit when we carry out repairs, in
some cases, such as when the memory
section is physically damaged, restoration
of the stored content may be impossible.
Roland assumes no liability concerning the
restoration of any stored content that has
been lost.
Maintenance
¹Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility
of discoloration and/or deformation.
Additional Precautions
¹Any data stored within the unit can be lost
as the result of equipment failure, incorrect
operation, etc. To protect yourself against
the irretrievable loss of data, be sure to
make a backup of the data stored within
it; or you may prefer to write down the
needed information.
¹Roland assumes no liability concerning the
restoration of any stored content that has
been lost.
¹Use a reasonable amount of care when
using the unit’s buttons, sliders, or other
controls; and when using its jacks and
connectors. Rough handling can lead to
malfunctions.
¹Never strike or apply strong pressure to the
display.
¹When disconnecting all cables, grasp the
connector itself—never pull on the cable.
This way you will avoid causing shorts, or
damage to the cable’s internal elements.
¹A small amount of heat will radiate from the
unit during normal operation.
¹To avoid disturbing others nearby, try to
keep the unit’s volume at reasonable levels.
¹When disposing of the packing carton
or cushioning material in which this unit
was packed, you must observe the waste
disposal regulations that apply to your
locality.

of health problems. Roland Corporation will
accept no responsibility for any such health
problems that may occur in yourself or in
viewers.
¹Do not use connection cables that contain a
built-in resistor.
¹This unit cannot be used to directly
connect to a network operated by
a telecommunications provider
(such as a mobile or landline-based
telecommunications company, an Internet

Outputting separate scenes to dierent output destinations (Dual mode)
There are two methods of outputting a scene: PGM/PST mode (factory setting)
and Dual mode.
For PGM/PST mode, only one scene is output. For Dual mode, two scenes can be
output independently.
This lets you select the optimal scene to match output destinations for dierent
purposes (example: for stage use and for streaming).
MEMO
¹You can use two video buses, PGM 1 and PGM 2 in Dual mode. You can also
set the video bus assignment for each output connector.
Scene switching is always performed as a freeze-frame cut.
¹The output method for scenes is set in System mode. For details on System
mode, refer to the Reference Manual (Roland website).
Output images in Dual mode
You can use the two built-in monitors on this unit to
select the scene to send to each video bus (PGM 1,
PGM 2).
Video Output: Overview
With the VR-400UHD, you can freely arrange multiple input videos and combine them into a single screen.
The combined video image is called a “scene”. You can switch between output videos for each scene. The scene preview is shown on the built-in
monitor, letting you check the preview while switching between scenes.
By preparing the scenes beforehand according to how the event proceeds, including the titles and captions as well as the screen layout, you can
smoothly operate this unit and produce a video with a live-action feel.
How the scenes are organized
Each scene is composed of three layers: a background layer, layer 1 and layer 2.
On each layer, you can display the input video signal from the HDMI 4K IN connector and the still images imported into this unit. You can also use
the crop function to cut out a certain part of the input video or still image.
It’s easy to create the screen layout you want just by enlarging or shrinking the layer window (display region) or by moving a window to the
desired location. You can also use the luminance key or chroma key on layers 1 and 2 to create a key composite video.

¹The layer stacking order cannot be edited.
¹You can choose whether to show or hide each
layer.
Number of scenes that can be created
Each group of eight scenes is managed as a“bank”.
The VR-400UHD has eight banks, so you can create a total of 64 scenes (8 scenes × 8 banks).
DSK layer
A DSK layer is positioned in front of the scenes. The DSK layer lets you use DSK composition to add video or text (titles, captions, etc.) to a scene.
SceneScene
DSK layer
¹Video on the DSK layer cannot be magnied or reduced.
¹In addition to the DSK layer, you can composite the still image from the
logo layer, but only for video output from the 4K STREAMING port.
What is a DSK (downstream keyer)?
DSK is a function that lets you composite more video and text on top
of an already composited video.
This is called “downstream keyer” because the key is composited in
the downstream process.
For DSK composition, you can use a luminance key, a chroma key or a
still image (.png) with an alpha channel as the alpha key.
