IMPORTANT NOTES

291a

In addition to the items listed under “USING THE UNIT SAFELY” on page 3, 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
speakers or other devices.

Placement

351

• Using the unit near power amplifiers (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.

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.

354a

• 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.

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.

Repairs and Data

452

• Please be aware that all data contained in the
unit’s memory may be lost when the unit is
sent for repairs. Important data should always
be written down on paper. During repairs,
due care is taken to avoid the loss of data.
However, in certain cases (such as when
circuitry related to memory itself is out of
order), we regret that it may not be possible to
restore the data, and Roland assumes no
liability concerning such loss of data.

5

IMPORTANT NOTES

Additional Precautions

553

• 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
losing important data, we recommend that
you periodically write down important data
you have stored in the unit’s memory on
paper.

552

• Unfortunately, it may be impossible to restore
the contents of data that was stored in the
unit’s memory once it has been lost. Roland
Corporation assumes no liability concerning
such loss of data.

553

• 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.

558a

• To avoid disturbing your neighbors, 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 (especially when it is late at night).

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.

562

• Use a cable from Roland to make the
connection. If using some other make of
connection cable, please note the following
precautions.

• 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 specifications, contact
the manufacturer of the cable.

Handling CD-ROMs

801

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

Copyright

852a

• When exchanging audio signals through a
digital connection with an external
instrument, this unit can perform recording
without being subject to the restrictions of the
Serial Copy Management System (SCMS).
This is because the unit is intended solely for
musical production, and is designed not to be
subject to restrictions as long as it is used to
record works (such as your own composi­tions) that do not infringe on the copyrights of
others. (SCMS is a feature that prohibits
second-generation and later copying through
a digital connection. It is built into MD
recorders and other consumer digital-audio
equipment as a copyright-protection feature.)

853

• Do not use this unit for purposes that could
infringe on a copyright held by a third party.
We assume no responsibility whatsoever with
regard to any infringements of third-party
copyrights arising through your use of this
unit.

Grounding terminal

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 infinitesimal electrical charge, which is
absolutely harmless. However, if you are concerned about this, connect the ground
terminal (see figure) 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 fire or explosion)

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

* You must leave this switch in the Off setting (toward the right) unless condenser

mics requiring a phantom power supply are connected to the XLR type jacks.
Malfunctions will occur if phantom power is supplied to dynamic mics or audio
playback devices. For details on the requirements of your mic, refer to the owner’s
manual for the mic you’re using.
(The UA-101’s phantom power supply is DC 48V, maximum of 20 mA.)

Installing the driver

In order to connect the UA-101 to your computer and
use it, you will need the correct driver.

This section explains how to install the driver you’ll need
when using the UA-101 in Hi-Speed USB mode on the
Windows XP operating system.

If you’re using the UA-101 in Full-Speed USB mode, you
must use the driver located in the
included CD-ROM.
For details on installation, refer to Readme_E.htm in the
respective folder.

If you’re using an operating system other than Windows
XP, use the appropriate driver from the USB1 folder of the
CD-ROM. Before you install the driver, be sure to read the
Readme_E.htm file located in each folder.

A driver is a piece of software
that passes data between the
UA-101 and an application
program running on your
computer when the UA-101 is
connected to your computer
via a USB cable. The driver
sends data from your
application software to the
UA-101, and sends data from
the UA-101 to your application
software.
