Owner’s Manual

Thank you, and congratulations on your choice of the Roland CUBE-15X Guitar Amplifier.

Before using this unit, carefully read the sections entitled

•IMPORTANT SAFETY INSTRUCTIONS (page 2)

•USING THE UNIT SAFELY (page 3–5)

•IMPORTANT NOTES (page 5)

Additionally, in order to feel assured that you have gained a good grasp of every

feature provided by your new unit, Owner’s manual should be read in its entirety.

The manual should be saved and kept on hand as a convenient reference.

Main Features

• 15-watt output, compact, high-performance guitar amp with built-in 20 cm (8-

inch) speaker; channel can be switched between “CLEAN” and “LEAD.”

• The LEAD channel provides four different distortion sounds: OVERDRIVE,

DISTORTION, METAL, and METAL STACK.

• The CUBE-15X includes Roland’s Power Squeezer function. This feature enables

you to reduce the maximum output from 15 watts to 2 watts at the press of a single

button. When switched on, Power Squeezer reproduces the distortion of a fully-

cranked power amp along with a great sound, regardless of the volume level, but

with a 2-watt output that is easy to handle in the home.

• Includes easy-to-use, three-band equalizer (Bass/Middle/Treble).

• Equipped with “RECORDING OUT jack” convenient for use in recording and for

use as headphone out.

• The unit is equipped with an external input jack, which is convenient for your

practice sessions. Use this to play along with sounds from CD players and MP3

players.

supply noise filter between this unit and the electrical outlet.

557

307

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

normal operation.

558a

• 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.

• To avoid disturbing your neighbors, try to keep the unit’s

308

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).

• Although the LEDs are switched off when the POWER

switch is switched off, this does not mean that the unit has

been completely disconnected from the source of power. If

you need to turn off the power completely, first turn off

the POWER switch, then unplug the power cord from the

power outlet. For this reason, the outlet into which you

choose to connect the power cord’s plug should be one

that is within easy reach and readily accessible.

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

• Use a cable from Roland to make the connection. If using

some other make of connection cable, please note the

following precautions.

Maintenance

401a

• 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 infor-

mation on cable specifications, contact the manufac-

turer of the cable.

• 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,

Wrap the power cord around the cord hook when trans-

porting or storing the unit.

Panel descriptions

Control Panel

1. INPUT Jack

10.AUX IN Jack

Connect your guitar here.

You can connect a CD player, MP3 player or other kind

of device and have it play along with your guitar.

This accepts a stereo miniature phone plug. However, the

speaker and RECORDING OUT/PHONES output is monaural.

Determine the volume level by adjusting the volume control of

the connected device.

2. SELECT Switch

Switches between the CLEAN and LEAD channels.

You can confirm which channel is selected by checking

the indicator’s color (CLEAN: green; LEAD: red).

CLEAN Channel

The Power Squeezer function is also applied to sounds input

from the AUX IN jack.

3. VOLUME Knob

Adjusts the CLEAN channel volume.

11. RECORDING OUT/PHONES Jack

When Using RECORDING OUT

Use mono 1/4” phone plugs when

connecting to this jack.

LEAD Channel

4. LEAD Channel

You can select from the following four types.

Volume level of RECORDING OUT can be

easily adjusted if you set the CLEAN or LEAD

Channel VOLUME knob as shown in the

diagram on the right.

OVERDRIVE

Natural distortion sound similar to that obtained by

turning an amp’s volume up completely.

When Using Headphones

Connect headphones to this jack.

DISTORTION

Harder distortion than OVERDRIVE.

No sound is played through the unit’s speaker while the

RECORDING OUT/PHONES jack is in use.

METAL

Even harder and heavier than DISTORTION, which can get

long sustained notes.

12. POWER SQUEEZER Switch

Switching on the Power Squeezer function allows you to

reduce the amp’s output to 2 watts.

METAL STACK

Very fat sound of a Heavy Metal full amp stack.

Switching this on allows you to produce a sound that

preserves the same tone and balance as when the amp is

played at maximum volume, but at an output of 2 watts, for

volume levels that are more suitable for the average home.

5. GAIN Knob

Adjusts the LEAD channel’s distortion level.

6. VOLUME Knob

Adjusts the LEAD channel volume.

13.POWER Switch

This switches the power on and off.

EQUALIZER

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.

7. BASS Knob

Adjusts the tone quality of the lower range.

8. MIDDLE Knob

If you need to turn off the power completely, first turn off the

POWER switch, then unplug the power cord from the power

outlet. Refer to “Power Supply” (p. 5).

Adjusts the tone quality of the midrange.

9. TREBLE Knob

Adjusts the tone quality of the upper range.

No sound will be produced when BASS, MIDDLE, and

TREBLE knob are all set to 0.

6. Before switching off the power, lower the volume on each of

the devices in your system and then TURN OFF the devices

in the reverse order to which they were switched on.

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. For protection from sudden big sound,

always make sure to have the volume level turned down before

switching on power. Even with the volume all the way down,

you may still hear some sound when the power is switched on

and off, but this is normal, and does not indicate a malfunction.

If you need to turn off the power completely, first turn off the

POWER switch, then unplug the power cord from the power

outlet. Refer to “Power Supply” (p. 5).

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.

Electric Guitar

Switching the Power On and Off

Before making the connections, be sure that the volume setting

of the VOLUME knob for both amplifiers is set to “0.”

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.

When connection cables with resistors are used, the volume

level of equipment connected to the inputs may be low. If this

happens, use connection cables that do not contain resistors,

such as those from the Roland PCS series.

and connected devices are set to 0.
