Important Notes

291a

In addition to the items listed under “USING THE UNIT SAFELY” on page 3 and 4, please read and observe the following:

Power Supply: Use of Batteries

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.

303a

• The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.

304a

• When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way, you can prevent malfunction and/or damage to speakers or other devices.

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.

360

• 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.

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 buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.

554

• Never strike or apply strong pressure to the display.

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

• 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.

Important Notes

Handling Hard Disks

Important Performance and Image Data

811

• Once a hard disk fails to function normally, all data that has been stored on it could be destroyed. All hard disks eventually wear out. We recommend that you consider the hard disk not as a permanent storage site, but as a place to store data temporarily. We also recommend that you back up important performance and image data that cannot be recorded again onto the external media that is supported by your device. For instructions on how to make such backups, refer to the owner’s manual for your device. Note that Roland assumes no liability whatsoever, including monetary compensation, for the loss of any recorded content in the event of the malfunction of, or physical damage to the hard disk, or for any direct or incidental damages resulting from the loss of such data.

Precautions Regarding Setup and Use

812

• Certain hard disk setup procedures and usage conditions may result in the corruption of recorded data, malfunctioning, or physical damage to the disk, so be sure to observe the following precautions.

• Do not subject the hard disk to vibration or shock, especially while the unit is in operation.

• Do not place in locations that experience vibrations, unstable locations, locations that are not level, or places with extremely large sound pressure (110 dB or more, see below). If recording is impossible due to vibration or sound

pressure, a message is displayed in advance. (P.21)

• Do not set up the unit in any location where it may be affected by vibration from external sources, or on any surface that is not stable and level.

• If the device includes a cooling fan, ensure that the fan and the side panel air vents remain unobstructed.

• Do not leave the unit in any environment subject to temperature extremes; for example, in a closed automobile in summer or outdoors during winter.

• Do not use the unit in conditions of high temperature and humidity or in any location subject to rapid temperature changes.

• Do not unplug the power cord or switch off any circuit breakers in the circuit to which the unit is connected while the power is turned on.

• Do not move the unit while the power is turned on or immediately after turning off the power. When transporting the unit, first turn off the power and confirm that the display screen has gone off, disconnect the power plug, then wait at least two minutes before moving the device.

* Examples of places with extremely large sound pressure are

under railroad bridges, within 2 meters of an automobile horn, or near a PA speaker.

Emergency Procedures

813

* The following procedures are to be used as emergency mea-

sures only, and are not recommended for normal operation.

• If the device fails to respond to operational commands or does not complete operations, turn off the power. If the power does not shut off following normal shutdown procedures, disconnect the power plug. If the unit does not operate normally when the power is turned on again, it may mean that the hard disk has been damaged. In such instances, consult your dealer or the nearest Roland Service Center. Note, however, that it may not be possible to recover any data from the hard disk once it has been lost. If your device features drive check capabilities, use the drive check function to regularly confirm that there are no problems, even when the device is operating normally. For more detailed information on the shutdown and drive check procedures, refer to the Owner’s Manual.

851

• Recording, duplication, distribution, sale, lease, performance, or broadcast of copyrighted material (musical works, visual works, broadcasts, live performances, etc.) belonging to a third party in part or in whole without the permission of the copyright owner is forbidden by law.

852a

• This product can be used to record or duplicate audio or visual material without being limited by certain technological copy-protection measures. This is due to the fact that this product is intended to be used for the purpose of producing original music or video material, and is therefore designed so that material that does not infringe copyrights belonging to others (for example, your own original works) can be recorded or duplicated freely.

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.

Remaining hard disk capacity

Remaining hard disk capacity Displays the amount of free memory on the internal hard disk.

Introducing the R-4 Pro

When the [DISPLAY] button is pressed twice while the Main screen is showing, the display changes to show the recording buffer capacity (BUF: buffer gauge).

Remaining buffuer capacity

The recording buffer is memory that temporarily stores the input sound before it is written to the hard disk. The buffer gauge indicates how much of the recording buffer has been used. Normally, the recording buffer never reaches capacity because input sound is immediately written to the hard disk. However, if data cannot be written to the hard disk or if the hard disk processing capacity decreases and writing data to the hard disk is delayed due to the R-4 Pro use environment (vibrations or sound pressure), then the data may accumulate to an excess and the buffer may overflow. (The hard disk processing capacity may be affected if file arrangement on the disk becomes irregular due to project files being repeatedly written and deleted.)

* When the recording buffer is close to capacity, the “HDD buffering” message is displayed. If vibration or sound

pressure may be the cause, take the R-4 Pro to a location where there is no vibration or sound pressure and check if the recording buffer capacity is restored.

* When the recording buffer reaches capacity, the buffer gauge moves all the way to the right edge and the “HDD

Slow!” message is shown. Recording does not stop even if the “HDD Slow!” message is displayed, but some sound is not recorded. This message will not disappear until a button is pressed.

* The same message is displayed if the hard disk processing capacity is diminished and writing to the hard disk is

delayed even in a location where there is no vibration or sound pressure. For important recordings, we recommend formatting the hard disk before use.

Introducing the R-4 Pro

What is a project?

On the R-4 Pro, th e data that you r ecord an d play back is ha ndled as a project. On the hard disk, each project actually consists of a folder with one or more files, as shown below. If you connect the R-4 Pro to your computer, you’ll be able to see how these folders and files are organized. However, if you change, delete, or rename the files within a project, the R-4 Pro may be unable to play back that project. Please use caution.

In the system settings, the Recording Setup parameter Rec Mode (p. 73) lets you specify the type of project you want to record.

Limitations on file size

The R-4 Pro can handle files up to 2 GB in size. If the file size reaches 2 GB during recording, the file is closed. Then, a new file is created and recording continues. When you finish recording, these files appear as separate projects.

About BWF

Files created during recording and editing are in BWF (Broadcast Wave Format). BWF files contain information about the recording time and recording device (EDIROL R-4 Pro) in addition to the data of a conventional WAV file. Of course, BWF files can be loaded by playback devices or audio editing software as conventional WAV files. When the Setup-Mode for “6 Timecode” (p. 66) in the system settings is “OFF,” files are created in WAV format.

Caution when copying files from your computer

Be aware of the following when copying files from your computer into the R-4 Pro’s internal hard disk.

• The R-4 Pro can only record linear PCM WAV files at sampling frequencies of 44.1, 48, 88.2, 96, or 192 kHz and bit depths of 16 or 24 bits. It cannot play back any other type of file.

• File and folder names containing double-byte characters (e.g., Japanese) will not be displayed correctly.

• Any files other than WAV files cannot be recognized by the R-4 Pro, and will be ignored.

• Files beginning with “.” (dot) will be ignored.

• You must not copy files larger than 2 GB into the R-4 Pro’s internal hard disk. Doing so will make the R-4 Pro’s operation unstable, and in the worst case might even damage the files in the internal hard disk.

A four-channel WAV file will be created with a name consisting of the project name and a.wav extension.

Project Name

* If you want to load these files onto your computer, make sure

that your waveform editing software supports four-channel files.
