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
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.
352
• This device may interfere with radio and television reception. Do not use this device in the vicinity
of such receivers.
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.
355
• To avoid possible breakdown, do not use the unit in a wet area, such as an area exposed to rain or
other moisture.
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
553*
• Use a reasonable amount of care when using the unit’s 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.

IMPORTANT NOTES
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.

Connections and driver installation (Macintosh)
* If you are a Windows user, refer to p. 9.
In order to use the UA-1A, you must first install a driver. UA1A uses a driver included with Mac OS.
Known issues: UA-1A
• Some applications such as Cakewalk’s Metro Series
and TC Work’s Spark Series cannot record/playback
at 48 kHz. Please use the UA-1A at 44.1 kHz.
• While the audio application is recording or playing,
do not connect/disconnect the USB cable. Doing so
may cause the application to freeze.
• You may hear sound hopping and/or noise when
you record and play back at the same time due to
high load on the CPU. However, the noise should
not be in the recording itself. Such noise should only
be found in the playback signal.
• If you are going to use the Virtual Sound Canvas 3,
you will need to select [Performance] from the
[Setting] menu, and set the Expression Mode to
Response Priority.
• The standard driver that comes with Mac OS is not
ASIO compatible.
• When you start up your computer with the UA-1A
connected, the computer may become unstable. If
this occurs, start up your computer before
connecting the UA-1A, and connect the UA-1A after
start-up.

Troubleshooting
• Does your computer or USB hub have sufficient power supply
• Does your computer meet the USB specifications?
• Is “Unknown Device” displayed for “Other devices” or “Universal
capacity?
The UA-1A cannot be connected if insufficient power is supplied to it. Check
whether one of the following cases apply.
If you are using the UA-1A with a notebook computer that is running on its
battery, operation may be unreliable with some models of computer. If this is
the case, connect the AC adaptor to your notebook computer.
The power conservation mode of your computer may limit the power that is
supplied to USB. Check the settings of your computer.
In some cases, the UA-1A cannot be used with a bus-powered hub (a hub that
does not contain a power supply). Please use a self-powered hub (a hub that
contains a power supply).
If you are using a computer that does not meet the USB specifications (such as
a homemade computer), operation may be unstable. In such cases, you may be
able to solve the problem by connecting a USB hub that contains a power
supply.

Troubleshooting
The “Add New Hardware Wizard” dialog box
appears even though you installed the drivers
If your computer or USB hub has two or more USB connectors, connecting the
UA-1A to a USB connector to which the UA-1A has never before been
connected may cause the Add New Hardware Wizard dialog box will appear
even though the drivers have already been installed. Install the drivers once
again as described in Connections and driver installation (Windows) (p. 9).
This is not a malfunction.
Drivers are not installed correctly
Use the procedure described in Deleting the USB Audio Device driver (p. 17)
to delete the USB Audio Device driver installed in your computer, and install
the UA-1A drivers once again as described in Connections and driver
installation (Windows) (p. 9). Check whether there is an item named
“Unknown Device” in “Other devices” or in “Universal Serial Bus
controllers.”
If you find “Unknown Device,” delete it.
A dialog box saying “Unknown Device found”
appears, and I can’t install the driver
Depending on your computer, not all of the Windows 98 files required to
support audio over USB may have been installed when the computer was
shipped.
Please check with the manufacturer of your computer.
