Thank you, and congratulations on your choice of BOSS CE-20 Dimensional Processor.
Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY”
and “IMPORTANT NOTES” (separate sheet).
These sections provide important information concerning the proper operation of the
unit. Additionally, in order to feel assured that you have gained a good grasp of every
feature provided by your new unit, this manual should be read in its entirety. The
manual should be saved and kept on hand as a convenient reference.
Main Features
●
Provides six chorus sound types, including newly developed “RICH,” “BASS,” and
“ACOUSTIC” sounds, plus CE-1 and SDD-320 modeling.
●
New “BRILLIANCE” control lets you adjust the guitar’s harmonic content and the chorus’s
characteristic glistening effect.
●
“AMBIENCE” control developed especially for chorus lets you add greater body and
richness to the chorus effect.
●
All inputs and outputs are stereo-compatible.
●
Internal preamp (+4 dBu) lets you apply chorus to guitar and bass amp sends and returns
even after sounds are created.
●
Comes equipped with a headphone jack, allowing you to use headphones for easy monitoring.
Batteries are supplied with the unit. The life of these batteries may be limited,
however, since their primary purpose was to enable testing.
Insert the included batteries as shown in figure, being careful to orient the batteries
correctly.
fig.02
• 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.
• Make sure the “+” and “–” ends of the batteries are oriented correctly.
• When the batteries run down, the POWER indicator gets dim. If this happens,
replace with new batteries.
• When replacing the batteries, use six AA type.
• Avoid using new batteries together with used ones. In addition, avoid mixing
different types of batteries. Doing so can result in fluid leakage.
• Battery life can vary depending on battery type.
Continuous usage time under battery power is about 10 hours with
alkaline batteries and about 4 hours with carbon batteries. (This may
vary according to usage conditions.)

Making the Connections
• The use of an AC adaptor is recommended as the unit’s power consumption is
relatively high. Should you prefer to use batteries, please use the alkaline type.
• 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.
• Use a cable from Roland to make the connection. If using some other make of
connection cable, please note the following precautions.
• 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.
• When the unit is running on battery power, the power comes on when you insert
the connector plug into the INPUT R (MONO) jack.
• 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.
• If there are batteries in the unit while an AC adaptor is being used, normal
operation will continue should the line voltage be interrupted (power blackout or
power cord disconnection).
• 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 powering up:Turn on the power to your guitar amp
When powering down: Turn off the power to your guitar amp
• 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, but this is normal, and does not indicate a
malfunction.
• 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.
• Turn on the power before you connect headphones. When turning off the power,
first unplug the headphones, then switch off the power.
• Please observe due caution when using headphones while the LEVEL switch is set
to +4 dBu, since their volume may get significantly higher.

Troubleshooting
The power doesn’t come on.
❍ Is the guitar connected correctly to the
INPUT R (MONO) jack?
→ Check the connections again (p. 3–9).
* When running off batteries, the unit won’t
switch on unless there’s something plugged
into the INPUT jack. This helps conserve the
batteries.
❍
Is the plug connected to the INPUT L jack?
→ When using battery power, connect the
plug to the INPUT R (MONO) jack.
❍ Have the batteries run down?
→ Replace with fresh batteries (p. 2).
❍ Is the specified AC adaptor (PSA-series
sold separately) connected correctly?
→ Check the connections again (p. 3–9).
There is no sound/volume
is too low.
❍
Is the other equipment connected correctly?
→ Check the connections again (p. 3–9).
❍ Is the volume turned down on the
connected guitar/bass amp, effects
processor, or other device?
→ Check the settings on the connected
equipment (p. 3–9).
❍ Is the LEVEL switch on the rear panel set
correctly?
→ Set the LEVEL switch to match the
connected equipment (p. 3–9).
❍ Is the direct sound ON/OFF set to OFF?
→ Only the effect sound is output when this is
set to OFF. When you want to output the
direct sound as well, set this to ON (p. 22).
❍ Is the effect level set to minimum?
→ Operate the E.LEVEL knob to adjust the
effect level.
Sound is distorted.
❍ Are the EFFECT TONE (LOW/HIGH),
BRILLIANCE, and AMBIENCE knobs
positioned correctly?
→ Sounds may become distorted with the
knobs at certain settings. Turn down one or
more of these knobs, or turn down the
E.LEVEL knob until the PEAK indicator
does not light up too frequently. If in spite
of these measures the sound is still
distorted, lower the output level of the
device connected to the INPUT jacks, or set
the LEVEL switch to AMPLIFIER SEND/
RETURN (+4 dBu).
Is the LEVEL switch set to GUITAR/BASS?
❍
→
When connecting to guitar amps, bass amps,
or other such gear, or when connecting to
equipment that outputs sound at high
volumes, set the LEVEL switch to
AMPLIFIER SEND/RETURN (+4 dBu).
Pressing the MEMORY/MANUAL
pedal does not call up the
intended memory.
❍ Is the proper Pedal mode set for your
current application?
→ The MANUAL/MEMORY pedal (or the
MANUAL/MEMORY pedal when pressed
simultaneously with EFFECT ON/OFF
pedal) functions differently according to the
Pedal mode settings. Use the most
appropriate setting for your particular
application (p. 11–12).
The volume level of the
instrument connected to INPUT
jack is too low.
❍ Could you be using a connection cable
that contains a resistor?
→ Use a connection cable that does not
contain a resistor.
