Using the JS-8 with Other Devices

Computer Expression Pedal (EV-5, etc.) Footswitch (BOSS FS-6, etc.) Security Slot USB Cable USB Memory Connector One of these can be connected. Ground Terminal SD Card Connector EXP PEDAL/ CTL1,2 Jack (p.SZ) USB Connector Cover Holder (indentation) SD Card USB Memory Top

About the Cover Holder (indentation)

If you detach the cover of the USB connector, place it in the cover holder so that it won't be lost.

Cover Holder Ground Terminal

About the Ground 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)

About the SD Cards and the SD Card Connector

Insert the SD card, label side up, into the slot in the JS-8's rear panel.

Press the inserted SD card until you hear an audible "click."

Recording and playback on the JS-8 requires an SD card.

Never insert or remove an SD card while this unit's power is on. Doing so may corrupt the unit's data or the data on the SD card.

Carefully insert the SD card all the way in-until it is firmly in place.

To prevent dust from entering the SD card connector and to prevent the SD card from being stolen, you should screw on the connector cover.

About the USB Memory Connector

Only USB memory can be connected to the USB memory connector. Do not connect devices such as a hard disk or CD-ROM drive.

About the Expression Pedal and Footswitch

Use only the specified expression pedals and foot switches (Roland EV-5, BOSS FV-500L, FV-500H, FS-5U, FS-6; sold separately). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.

Never connect or disconnect the expression pedal or the footswitch while this unit's power is on.

The trademarks listed in this document are trademarks of their respective owners, which are separate companies from Roland/BOSS. Those companies are not affiliated with Roland/BOSS and have not licensed or authorized BOSS's JS-8. Their marks are used solely to identify the equipment whose sound is simulated.

Internal Effects

With the JS-8, you can use seven effects types simultaneously in a single effects patch, including AMP (amp modeling), FX (various effects), EQ (equalizer), NS (noise suppressor), DELAY (delay), CHORUS (chorus), and REVERB (reverb).

For the FX type, you can select among compressor, distortion, wah, and a wide variety of other effects.

Internal Effects
AMP (amp modeling)	Models sounds passed through guitar and bass amps.COSM modeling simulates not just preamp and speaker characteristics, but even miking as well.You can select from a large number of different amp types. . "AMP parameter list" ("MIC TYPE" (p. 24)
FX (effects)	Provides a wide variety of effects to choose from, including compressor, distortion, wah, and many others. . "FX parameter list" (p. 29)
EQ (equalizer)	Adjusts the volume levels for different frequencies in the low-frequency to high-frequency ranges.Low and high midrange settings feature parametric equalization. . "EQ parameter list" (p. 28)
NS (noise suppressor)	This effect suppresses noise and hum from the guitar's pickups.Since the noise reduction follows the guitar sound's envelope (the change in volume over time), it has practically no influence on the guitar sound itself, thus producing a highly natural effect. . "NOISE SUPPRESSOR parameter list" (p. 28)
DLY (delay)	A delayed sound is added to the normal guitar sound, producing a thicker tone with a distinctive ambience. . "DELAY parameter list" (p. 29)
CHO (chorus)	This effect adds a subtle frequency modulation, producing a beautiful sound with greater breadth and body. . "CHORUS parameter list" (p. 30)
REV (reverb)	This effect adds reverberation and other spatial effects.Set the REVERB TYPE to choose from a variety of different types of reverb sound. . "REVERB parameter list" (p. 30)

USB AUDIO ROUTING Description USB AUDIO ROUTING Description
DEFAULT	Select this setting when using the JS-8 as a USB audio interface or when playing the guitar while playing back songs with the computer.	RE-AMP	Select this setting when "re-amping" guitar sounds that were previously recorded without any effects added.MEMOUse the GUITAR LEVEL knob to adjust the volume level that's output from the USB connector of the JS-8.
GUITAR (EFX)	Select this setting when playing the guitar while playing back songs with the computer or when using the computer to record guitar sounds with effects added.	DIRECT OFF	Select this setting when playing audio from the computer as is.MEMOWith this setting, you cannot play guitar sounds directly through the JS-8's speakers.The only sound that can be played through the speakers is audio from the computer.
GUITAR (DRY)	Select this setting when playing the guitar while playing back songs with the computer or when using the computer to record guitar sounds without any effects added.MEMOWith this setting, you can still monitor the guitar sound with effects, but the DAW will capture the sound before effects are applied.	MEMOIf you turn the JS-8's power off with USB AUDIO ROUTING set to RE-AMP or DIRECT OFF, it will be set to DEFAULT the next time you turn the power on.

MEMO

What is "Re-Amping?"

This is a technique in which a guitar sound is recorded directly into a DAW without any effects, then played back through effects later to create a finished guitar sound after the fact. The advantage of re-amping is that, even after recording, you can use your recorded performance as is to create new sounds. This technique is particularly advantageous if you've ever recorded your guitar with effects added, and then later realized you were unhappy with the results, or found that the guitar gets "lost in the mix" after other parts are added.

With re-amping, you can focus on recording a great performance instead of worrying about getting the perfect effects sound. Once your performance has been recorded dry, you can then play it back through the JS-8's effects, adjust the sound just the way you want it, and then record the result as a new track in the DAW.

When you intend to record a sound dry and re-amp it later, choose GUITAR (DRY) as the JS-8's USB audio routing. This allows you to monitor the live guitar sound with effects (for inspiration during recording) while sending the dry sound to the DAW software. To play recorded audio from the DAW through the JS-8's effects, select RE-AMP as the USB audio routing.

Troubleshooting

Power not turning on

- Make sure the JS-8's AC adaptor is properly connected to the power outlet and the JS-8 (p. 4).

No sound

• Is the MASTER LEVEL knob turned down? (p. 8)

• Is the SPEAKER switch set to OFF? (p. 31)

• Are there any songs on the SD card?

Recorded sound is distorted

• Could the guitar level be excessive?

Adjust the GUITAR LEVEL (p. 8) or SONG LEVEL (p. 38) so that does not light.

Can't play MP3/WAV file

• Are the MP3 file's sampling rate and bit rate or the WAV file's sampling rate and quantization bit rate supported by the JS-8? [p. 3]
• Increasing the playback speed or changing the pitch of MP3s with higher bit rates may not be effective in playing back these files. In such cases, convert the song to JS-8 format. [p. 38]

ALWAYS OBSERVE THE FOLLOWING

WARNING

Do not open (or modify in any way) the unit or its AC adaptor.

Do not attempt to repair the unit, or replace parts within it (except when this manual provides specific instructions directing you to do so). Refer all servicing to your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" page.

Never install the unit in any of the following locations.

• Subject to temperature extremes (e.g., direct sunlight in an enclosed vehicle, near a heating duct, on top of heat-generating equipment); or are
• Damp (e.g., baths, washrooms, on wet floors); or are
• Exposed to steam or smoke; or are
• Subject to salt exposure; or are
• Humid; or are
• Exposed to rain; or are
  • Dusty or sandy; or are
• Subject to high levels of vibration and shakiness.

Make sure you always have the unit placed so it is level and sure to remain stable. Never place it on stands that could wobble, or on inclined surfaces.

Be sure to use only the AC adaptor supplied with the unit. Also, make sure the line voltage at the installation matches the input voltage specified on the AC adaptor's body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.

Use only the attached power-supply cord. Also, the supplied power cord must not be used with any other device.

WARNING

Do not excessively twist or bend the power cord, nor place heavy objects on it. Doing so can damage the cord, producing severed elements and short circuits. Damaged cords are fire and shock hazards!

This unit, either alone or in combination with an amplifier and headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level, or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should immediately stop using the unit, and consult an audiologist.

Do not allow any objects (e.g., flammable material, coins, pins); or liquids of any kind (water, soft drinks, etc.) to penetrate the unit.

Immediately turn the power off, remove the AC adaptor from the outlet, and request servicing by your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" page when: The AC adaptor, the power-supply cord, or the plug has been damaged; or

• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been spilled onto the unit; or
• The unit has been exposed to rain (or otherwise has become wet); or
  • The unit does not appear to operate normally or exhibits a marked change in performance.

In households with small children, an adult should provide supervision until the child is capable of following all the rules essential for the safe operation of the unit.

WARNING

Protect the unit from strong impact. (Do not drop it!)

Do not force the unit's power supply cord to share an outlet with an unreasonable number of other devices. Be especially careful when using extension cords-the total power used by all devices you have connected to the extension cord's outlet must never exceed the power rating (watts/amperes) for the extension cord. Excessive loads can cause the insulation on the cord to heat up and eventually melt through.

Before using the unit in a foreign country, consult with your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" page.

CAUTION

The unit and the AC adaptor should be located so their location or position does not interfere with their proper ventilation.

Always grasp only the plug on the AC adaptor cord when plugging into, or unplugging from, an outlet or this unit.

At regular intervals, you should unplug the AC adaptor and clean it by using a dry cloth to wipe all dust and other accumulations away from its prongs. Also, disconnect the power plug from the power outlet whenever the unit is to remain unused for an extended period of time. Any accumulation of dust between the power plug and the power outlet can result in poor insulation and lead to fire.

CAUTION

Try to prevent cords and cables from becoming entangled. Also, all cords and cables should be placed so they are out of the reach of children.

Never climb on top of, nor place heavy objects on the unit.

Never handle the AC adaptor or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit.

Before moving the unit, disconnect the AC adaptor and all cords coming from external devices.

Before cleaning the unit, turn off the power and unplug the AC adaptor from the outlet (p. 4).

Whenever you suspect the possibility of lightning in your area, disconnect the AC adaptor from the outlet.

Should you remove connector covers, screw, ground terminal, and SD cards, keep them in a safe place out of children's reach, so there is no chance of them being swallowed accidentally.

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 (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.

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

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

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.

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 off.

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 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.

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

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.

Repairs and Data

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 backed up on USB memory or computer, or written down on paper (when possible). 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.

Additional Precautions

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 that you periodically save a backup copy of important data you have stored in the unit's memory on USB memory or computer.

Unfortunately, it may be impossible to restore the contents of data that was stored on USB memory or computer once it has been lost. Roland Corporation and BOSS Corporation assume 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.

Never strike or apply strong pressure to the display.

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.

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).

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.

Use only the specified expression pedal (Roland EV-5, BOSS FV-500L, or FV-500H; sold separately). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.

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.
