Making the Connections and Turning the Power On

te Step

Switch on the amps power last!

Electric guitar

When connecting, turn down the volume all the way on all equipment!
Be sure to use a BOSS PSA-series adaptor. The use of any other adaptor may cause damage or malfunction.

Guitar a mp

Connect the equipment to the OUTPUT jack.
PSA-series AC adaptor (sold separately)
Connect a commercially available anti-theft security cable here. http://www.kensington.com/
Insert the plug into the INPUT jack to power up the ME-25.
PCS-31L cable, etc. (sold separately)
The INPUT jack doubles as the power switch. Power to the unit is turned on when you plug into the INPUT jack; the power is turned off when the cable is unplugged.
You can mix stereo audio from AUX IN with the output.
Digital audio player, etc.
The battery compartment is located on the underside.
Insert the included batteries, taking care to orient them correctly.
When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the buttons and controls. Also, you should try to orient the unit so no buttons or controls get damaged. When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over. If used improperly, batteries may explode or leak and cause damage or injury. In the interest of safety, please read and observe the following precautions. Carefully follow the installation instructions for batteries, and make sure you observe the correct polarity. Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries. Remove the batteries whenever the unit is to remain unused for an extended period of time. If a battery has leaked, use a soft piece of cloth or paper towel to wipe all remnants of the discharge from the battery compartment. Then install new batteries. To avoid inflammation of the skin, make sure that none of the battery discharge gets onto your hands or skin. Exercise the utmost caution so that none of the discharge gets near your eyes. Immediately rinse the affected area with running water if any of the discharge has entered the eyes. Never keep batteries together with metallic objects such as ballpoint pens, necklaces, hairpins, etc.

Stereo headphones

Digital recorder, etc.
Inserting a plug into the PHONES jack automatically activates the built-in guitar amp simulator, enabling you to enjoy a natural guitar sound when using headphones. When youre connecting the ME-25s OUTPUT to a normal guitar amp, disconnect the plug from the PHONES jack.
Expected battery life under continuous use: Carbon: 3 hours, Alkaline: 9 hours These figures will vary depending on the actual conditions of use. When operating on battery power only, the unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible. We recommend that you keep batteries installed in the unit even when you're powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.
About connecting the ME-25 to the other devices
Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. Raise the amp volume only after turning on the power to all connected devices. This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally. When connection cables with resistors are used, the volume level of equipment connected to INPUT and AUX IN may be low. If this happens, use connection cables that do not contain resistors. The ME-25 has no built-in amp or speakers. To hear sounds, youll need to provide a guitar amplifier, stereo headphones, or other such equipment. For mono output, connect a cable to the L/MONO jack only. If you want to send the output from the PHONES jack to a recorder or other device, use a connection cable such as the PCS-31L (available separately). The PCS-31L has a stereo phone plug on one end, and two phone plugs on the other end. If, instead, you were to use an ordinary guitar cable, only the sound of the L channel would be available in the output. On the ME-25, the level of the signal input via AUX cannot be adjusted. Youll need to perform that adjustment on the equipment youve connected. When needing to monitor the sound being input, first turn down the volume all the way on the device youve connected. Then, gradually raise the level until youve reached the appropriate volume.

Pressing this pedal for two seconds or longer enables the Phrase Loop feature.

Phrase Loop Play (p. 10)

You can save the settings you've adjusted. Saving Sounds (Memory Write) (p. 4)
Should you encounter unexpected results, such as no sound being produced, check the following. Are connections to other devices correctly made? Check the connections once more. Is the volume turned down? Check the volume levels on any connected amp or mixer. Has the level been lowered with the expression pedal? When the expression pedal is set to control volume, sounds are not output when the toe of the pedal is in the raised position.

Using the Sound Library

Whats the Sound Library?

The Sound Library contains sounds in a variety of styles. You can obtain ideal sounds with ease, simply by selecting a sound provided in the Sound Library. Six categories are available (CLEAN, CRUNCH, DRIVE, HEAVY, LEAD, and EXTREME), with ten different variations provided for each.
For information on Sound Library sounds, read the separate Sound Library List.
You can download a variety of the Sound Library sounds from the BOSS website (http://www.bosscorp.co.jp/sound/ME-25/). You can import downloaded sound libraries into the ME-25 using Librarian (p. 11).
1. Choose the category you want.
SL will appear in the display.
2. Choose the variation you want. 3. Press [EXIT].
This completes the procedure for selecting sounds from the Sound Library.
Sounds cannot be added and saved in the Sound Library using the ME-25 itself. Sounds that you like and want to reuse should be saved in memory (Memory Write).
When saving the sounds in memory, placing them in the order that you intend to use during the performance will be helpful.
Saving Sounds (Memory Write)
This saves the current effect, noise suppressor, and control settings in a memory.

1. Press [WRITE].

The memory number shown in the display will start blinking.
Until you perform a Memory Write operation, switching off the power or changing memories will cause any tones youve created to be lost. Carrying out a Memory Write operation causes the sound already saved at the destination memory to be lost.
2. Use the MEMORY pedals to choose the memory
number where youd like to save the memory.
Pressing and holding a pedal lets you switch memories successively.
To cancel the Memory Write procedure, press [EXIT].

3. Press [WRITE] again.

The memory number will blink more rapidly, indicating that the sound has been saved.
To copy a memory, call up the memory you want to copy, then simply carry out a Memory Write operation. You can copy the memory by choosing a different memory number and saving it there.

Use only the specified AC adaptor (PSA series), and make sure the line voltage at the installation matches the input voltage specified on the AC adaptors 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... 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...
Never expose Battery to excessive heat such as sunshine, fire or the like.

Placement

Repairs and Data

Handling DVD-ROMs

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.

Please be aware that all data contained in the units memory may be lost when the unit is sent for repairs. Important data should always be backed up on a 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.
Avoid touching or scratching the shiny underside (encoded surface) of the disc. Damaged or dirty DVD-ROM discs may not be read properly. Keep your discs clean using a commercially available DVD cleaner.

Copyright

Additional Precautions
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.
Power Supply: Use of Batteries
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 units memory on a computer. Unfortunately, it may be impossible to restore the contents of data that was stored in the units memory or computer once it has been lost. BOSS/ Roland Corporation assumes no liability concerning such loss of data. Use a reasonable amount of care when using the units buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions. 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 cables internal elements. To avoid disturbing your neighbors, try to keep the units 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. 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.

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. If youll be using the ME-25 for an extended time, we recommend that you use an AC adaptor. If you prefer to use a battery, we recommend an alkaline battery. Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and/or damage to speakers or other devices. Batteries are supplied with the unit. The life of these batteries may be limited, however, since their primary purpose was to enable testing. 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.

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.
