Roland Stereo Amplifier CUBE 15x User Guide

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.

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2,  
3, 4 and 5, please read and observe the following:

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.

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.
