About the Roland SPACE ECHO RE-201
The Roland SPACE ECHO RE-201 tape echo
debuted in 1974. Even today, with the machine
no longer in production, it remains a worldfamous device that is still widely acclaimed.
The sound of the RE-201, especially the
pleasing chorus effect created by the subtle
wavering from the movement of the tape—
and the characteristic compressed sound
that results from magnetic saturation of the
tape—continues to intrigue numerous
musicians.

Adjusts the input levels for
Inputs A and B.
* You can adjust the input level
with the INPUT VOLUME
knob regardless of whether the
effect is switched on or off.
ECHO VOLUME Knob
Adjusts the volume of the echo.
The volume of the echo sounds increases
as the knob is turned further to the right.
INTENSITY Knob
This adjusts the volume of the echo repeat sound (the feedback
volume). The volume of the feedback increases as the knob is
turned further to the right. With certain sounds and knob settings,
you can also produce oscillation.

Panel Descriptions
POWER Indicator
This indicator shows whether the power is on or off, and also functions as a battery-check indicator.
* When the indicator starts to dim or fails to light, the batteries are exhausted. When this occurs, install
new batteries. For instructions on replacing the batteries, refer to “Installing Batteries” (p. 6).
TAP Indicator
EFFECT ON/OFF Indicator
This lights up when the effect is on.
This flashes in time with the delay
time set by the tap input.
* The light is turned off when the twist
effect is applied.
EFFECT ON/OFF Pedal
This alternately switches the effect on
or off each time the pedal is pressed.
Even when the effect is switched off,
the echo sounds still fade gradually.
* Turning up the INTENSITY knob
causes the echo sounds to continue.
Virtual Tape Display
The movement of the light provides a visual
image resembling a running tape.
The movement of the light is synchronized to
the virtual tape speed.

TAP Pedal
You can set the delay time (tap
delay time) by briefly depressing
this pedal at the desired tempo (tap
input). Also, you can obtain the
“twist” effect by keeping the pedal
depressed (p. 14).
* The maximum values that can be set
for the tap delay time in Normal/
Long mode and Variation mode
differ (p. 18).

INPUT Jacks
(INPUT A/MONO, B)
These input jacks are used for
connecting electric guitars, keyboards,
other instruments, and effects
processors.
Connect mono instruments or effects to
the A/MONO jack.
“Making the Connections” (p. 7)
* The A/MONO jack also doubles as the
power switch. The power comes on when a
plug is inserted into the A/MONO jack,
and goes off when it is unplugged.
Unplug any connected cords when the
unit is not in use.
OUTPUT Jacks
(OUTPUT A/MONO, OUTPUT B)
Use these jacks to connect the RE-20 to a guitar
amp, a keyboard amp, or to an effects
processor, mixer, multitrack recorder, or other
such device.
When connected to both A/MONO and B, a stereo effect can be obtained when reverb is applied.
If you are using the RE-20 in mono, connect to
the A/MONO jack only.
“Making the Connections” (p. 7)
EXP Pedal Jack
Connect an optional expression pedal (such as the
Roland EV-5) to this jack.
Once connected, the pedal can be used to control
the repeat rate and intensity in real time.
“Control Using an Expression Pedal” (p. 16)
DIRECT Switch
This switches the direct sound on and off.
If you want to turn off output of the
direct sound, set the DIRECT switch
to OFF.
DC IN (AC Adaptor)
Jack
This jack is for connecting an
AC adaptor (BOSS PSA series,
sold separately).
Using an AC adaptor makes
possible long performances
without worrying about your
batteries going dead.
* When you are using an AC
adaptor, be sure to use only the
specified type (PSA series).
Using an adaptor other than
the specified type may cause
the unit to malfunction, or
cause damage to the unit.

Installing Batteries
Insert the batteries as shown below, being careful to orient the batteries correctly.
fig.010
• 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 it 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.
• Batteries are supplied with the unit. The life of these batteries may be limited,
however, since their primary purpose is to enable testing.
• When the batteries run down, the POWER indicator grows dim. If this happens, install
with new batteries.
• When replacing the batteries, use six AA type batteries.
• 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 32 hours with alkaline batteries
and about 9 hours with carbon batteries. (This may vary according to usage
conditions.)

Making the Connections
• When using an AC adaptor, be sure to use only the specified type (PSA series; sold
separately).
Using an adaptor other than the specified type may cause the unit to malfunction, or
cause damage to the unit.
• To prevent malfunction and/or damage to speakers or other devices, always turn
down the volume and turn off the power to all devices before making any connections.
• 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.
• Some connection cables contain resistors. When connection cables with resistors are
used, the sound level may be extremely low, or impossible to hear. For information on
cable specifications, contact the manufacturer of the cable.
• The INPUT A/MONO jack doubles as a power switch. Inserting a plug in the INPUT
A/MONO jack turns on the power; the power is switched off when the plug is
disconnected. Be sure to unplug the cable from this jack when the RE-20 is not in use.
• 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 POWER indicator will become dim when
battery power gets too low. Replace the batteries as soon as possible.
• This unit is equipped with a protection circuit. A brief interval (a few seconds) after powerup is required before the unit will operate normally.
