At regular intervals, be sure to pull out the power plug, and using a dry cloth,

wipe away any dust or foreign objects that may have accumulated.

Disconnect the power plug whenever the unit will not be used for an extended period of time

Fire may result in the unlikely event that a breakdown occurs.

Route all power cords and cables in such a way as to prevent them from getting entangled

Injury could result if someone were to trip on a cable and cause the unit to fall or topple.

Precautions concerning use of phantom power supply

Always turn the phantom power off when connecting any device other than condenser microphones that require phantom power. You risk causing damage if you mistakenly supply phantom power

to dynamic microphones, audio playback devices, or other devices that don’t require such power. Be sure to check the specifications of any microphone you intend to use by referring to the manual that came with it.

(This instrument’s phantom power: 48 V DC, 14 mA Max)

Do not remove the speaker grille and speaker

IMPORTANT NOTES

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 or a motor (such as a refrigerator, washing machine, microwave oven, or air conditioner). 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.

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 unit may interfere with radio and television reception. Do not use this unit 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 allow lighting devices that normally are used while their light source is very close to the unit (such as a piano light), or powerful spotlights to shine upon the same area of the unit for extended periods of time. 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.

•Do not paste stickers, decals, or the like to this instrument. Peeling such matter off the instrument may damage the exterior finish.

•Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface.

•Do not place containers or anything else containing liquid on top of this unit. Also, whenever any liquid has been spilled on the surface of this unit, be sure to promptly wipe it away using a soft, dry cloth.

Maintenance

•To clean the unit, use a dry, soft cloth; or one that is slightly dampened. Try to wipe the entire surface using an equal amount of strength, moving the

cloth along with the grain of the wood. Rubbing too hard in the same area can damage the finish.

•Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Repairs and Data

•Before sending the unit away for repairs, be sure to make a backup of the data stored within it; or you may prefer to write down the needed information. Although we will do our utmost to preserve the data stored in your unit when we carry out repairs, in some cases, such as when the memory section is physically damaged, restoration of the stored content may be impossible. Roland assumes no liability concerning the restoration of any stored content that has been lost.

Additional Precautions

•Roland assumes no liability concerning the restoration of any stored content that has been lost.

•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.

•When 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.

•A small amount of heat will radiate from the unit during normal operation.

•To avoid disturbing others nearby, try to keep the unit’s volume at reasonable levels.

•Do not use connection cables that contain a built-in resistor.

[NOTCH] knob

If turning on the [PHASE] button does not help, adjust the

[NOTCH] knob.

55 While acoustic feedback is occurring, turn the [NOTCH] (frequency) knob to find the location at which feedback is suppressed.

55 Turning the knob toward the right suppresses feedback at a higher frequency; turning the knob toward the left suppresses feedback at a lower frequency.

[ON] button

Switches HARMONY on/off.

[TYPE] button

Selects the type of harmony. The type switches each time you press the button.

	Type	Explanation
	HIGH	Adds harmony above the vocal sound that is

		vocalist records the same melody a second time,
		adding richness to the sound.
	LOW	Adds harmony below the vocal sound that is
		input.

*You can specify the reference pitch used when the harmony is added. For details, refer to “Specifying the Harmony Reference Pitch” (p. 8).
