IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on page 3–4, please read and observe the following:
Power Supply
301
• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled by
an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. 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 filter between this unit and the
electrical outlet.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to other devices.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce noise or
unstable image on video output. To alleviate the problem,
change the orientation of this unit; or move it farther away
from the source of interference.
352a
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
352b
• Noise 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 off.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, 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.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Additional Precautions
551
• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend to take
memo of your important data (settings etc.) you have
stored in the unit’s memory dial.
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in memory dial once it has been
lost. Roland /Edirol assumes no liability concerning such
loss of data.

• Use 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.
556
• When connecting / 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.
558b
• To avoid disturbing your neighbors, try to keep the audio
volume at reasonable levels (especially when it is late at
night) if you enjoy listening to music.
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.

Welcome
Thank you, and congratulations on your choice of the Edirol V-4. The V-4 is a video mixer/effects
processor that delivers image quality rivaling professional equipment, and provides four channels
of video input.
With a rich array of inputs and easy operation, the V-4 allows performances and presentations that
include images to be made more expressive than ever before.
The V-4 can also be controlled from external MIDI devices. Images projected on the stage can be
controlled while you play an instrument, adding impressive impact to a stage performance.
We hope you will enjoy the V-4’s versatile video functionality in a wide range of applications.
9
Features of the V-4
Features of the V-4
Four-channels of video inputs
The V-4 provides two S-video inputs and four video (composite) inputs. Of the four channels 1
through 4, S-video can be used for inputs 1 and 2. If both S-video and video (composite) are input
to channels 1/2, the S-video input will take priority and will be automatically selected.
Two independent frame synchronizers
Even when using unstable video input signals such as VHS and Hi-8, the frame synchronizers
within the V-4 will correct the synchronization signal. This means you can use a wide range of
image sources without worrying about noise produced by degradation of the synchronization
signals.
High-quality digital effects
Effects are processed digitally. Diverse and high-quality effects such as Picture In Picture, Mirror,
and Multi can be independently applied to both channels A and B.
Simple operation
Switching and mixing video sources is extremely easy. The T-bar type video fader can be installed
in either the horizontal or vertical orientation, whichever you prefer.
Preview function
Before switching sources, you can use a preview TV screen to view the images being input on each
channel without affecting the output image.
Switching and effects synchronized to music
The V-4 lets you tap BPM (Beats Per Minute) to switch images or control effects. This is particularly
useful when music and video need to be synchronized, such as in a video jockey performance.
Control from external MIDI devices
The V-4 provides MIDI connectors. An external MIDI device can control effects and switching
images. Setup is particularly easy if a Roland or Edirol product that supports V-LINK is
connected—simply press the V-LINK button on the control device.

About Ground Terminal
In some cases, depending on the environment in which the unit is installed, the surface of the panel
may sometimes feel rough and grainy. This is due to an infinitesimal electrical charge, which is
absolutely harmless. However, if you are concerned about this, connect ground terminal (see
figure) with an external ground. When the unit is grounded, a slight noise may result, depending
on the particulars of your installation. If you are unsure of the connection method, contact nearest
Roland/Edirol
“Information” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)

Connecting peripheral devices
This section explains how to connect your peripheral devices to the V-4. You can connect up to four video
playback devices (sources). Here’s how to connect sources such as a video camcorder, VCR, DVD player, or DV7PR, and play them back to create an impressive video performance. To prevent malfunction and/or damage to
other devices, always turn down the volume, and turn off the power on all devices before making any connections.
Typical connection example
* The V4 does not have audio inputs so will not mix audio. Audio outputs can be connected directly to speakers or via an
audio mixer if mixing of audio from multiple devices is necessary.
* No video cables come with this product. Please use appropriate video cables for connection with source devices or TV
monitor/Projector.
* It is recommended to use composite cable rather than S-video cable where you need to connect devices long distances
(unless using S-video amplifiers). If devices are installed closer to the V-4, it is recommended to use S-video cables so that
you can obtain better image quality.
* If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the S-
video signal will take priority.

Video signal flow
The video signals received from the four input jacks are assigned to channels A or B of the video
mixer. (These assignments are made manually.) The signal of A and B channels are processed by
the video mixer section, and sent via the output fader to the output jack.
* Various setting menus like effect parameters are displayed on preview monitor.
* If both video (composite) and S-video signals are input simultaneously to the same channel (channel 1 or 2 only), the S-
video signal will take priority.
* When switching on Preview Selector is done, image on preview monitor may flicker briefly. This does not affect image
from output jacks.
