If you remove the screw from the ground
terminal, be sure to replace it; don’t leave it
lying around where it could accidently be
swallowed by small children. When refastening
the screw, make that it is rmly fastened, so it
won’t come loose.

Precautions concerning use of phantom
power supply

Unless condenser microphones requiring
phantom power are connected to the XLR
connectors, you must leave the phantom
power turned o Supplying phantom power to
a dynamic microphone or to an audio playback
device may cause malfunctions. For details on
the requirements of your microphone, refer to
its owner’s manual.
(The DUO-CAPTURE EX’s phantom power
supply is DC 48 V, 6 mA for INPUT 1 and INPUT
2 combined.)

Handle leaking batteries carefully

• If uid has leaked from a battery, make sure
not to touch it with your bare hands.

• If any of the leaking uid gets into your
eyes, the loss of vision may result. Do not
rub your eyes; use clean water to ush them
thoroughly. Then, promptly see a doctor.

• Burning of the skin or dermatitis may result
if uid has gotten onto your skin or clothing.
Use clean water to ush aected areas
thoroughly; then, promptly see a doctor.

• Using a soft cloth, carefully wipe any
remaining uid from the inside of the battery
compartment. Then, install new batteries.

IMPORTANT NOTES

Power Supply

• Do 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.

• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.

• To prevent malfunction and equipment failure,
always make sure to turn o the power on all your
equipment before you make any connections.

• When using the optional AC adaptor, the DUO­CAPTURE EX will automatically be switched o after
10 consecutive hours of no communication with the
computer. After the power is automatically switched
o, turn the power o and then on if you want to use
the DUO-CAPTURE EX again.

Power Supply: Use of Batteries

• When installing or replacing batteries, always turn
this unit o and disconnect any other devices you
may have connected. This way, you can prevent
malfunction and damage.

• The life of the supplied batteries may be limited,
since its primary purpose was to enable testing.

• When operating this unit using batteries, please use
alkaline batteries or rechargeable Ni-MH batteries.

• This unit will not operate using batteries or bus
power unless the AC adaptor is disconnected.

• Even if batteries are installed, the unit will turn o
if you connect or disconnect the power cord from
the AC outlet while the unit is turned on, or if you
connect or disconnect the AC adaptor from the unit.
You must turn o the power before you connect or
disconnect the power cord or AC adaptor.

Placement

• Using 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.

• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.

• 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 o.

• Do not expose the unit to direct sunlight, place
it near devices that radiate heat, leave it inside
an enclosed vehicle, or otherwise subject it to
temperature extremes. Excessive heat can deform or
discolor the unit.

• When 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.

• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If you
do so, please make sure that the unit will not slip or
move accidentally.

• Do not put anything that contains water on this unit.
Also, avoid the use of insecticides, perfumes, alcohol,
nail polish, spray cans, etc., near the unit. Swiftly wipe
away any liquid that spills on the unit using a dry,
soft cloth.

41

IMPORTANT NOTES

Maintenance

• 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.

• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.

• 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.

• When 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.

• To avoid disturbing others nearby, try to keep the
unit’s volume at reasonable levels. You may prefer
to use headphones, so you do not need to be
concerned about those around you.

• 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.

• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to
this unit. The use of such cables can cause the sound
level to be extremely low, or impossible to hear. For
information on cable specications, contact the
manufacturer of the cable.

Handling CDs / DVDs

• Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty
CD/DVD discs may not be read properly. Keep your
discs clean using a commercially available CD/DVD
cleaner.

Grounding

• Depending on the circumstances of a particular
setup, you may experience a discomforting
sensation, or perceive that the surface feels gritty to
the touch when you touch this device, microphones
connected to it, or the metal portions of other
objects, such as guitars. This is due to an innitesimal
electrical charge, which is absolutely harmless.
However, if you are concerned about this, connect
the ground terminal (see gure) with
an external ground. When the unit is
grounded, a slight hum may occur,
depending on the particulars of your
installation. If you are unsure of the
connection method, contact the
nearest Roland Service Center, or an
authorized Roland distributor, as listed
on the “Information” page.

Unsuitable places for connection

• Water pipes (may result in shock or electrocution)

• Gas pipes (may result in re or explosion)

• Telephone-line ground or lightning rod (may be
dangerous in the event of lightning)
