Roland Music Mixer RE 20 User Guide

Thank you, and congratulations on your choice of the BOSS RE-20 Space Echo.  
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 understanding 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  
The RE-20 uses COSM technology to faithfully simulate the characteristics of the famed  
Roland SPACE ECHO RE-201.  
Faithfully reproduces the characteristics of the RE-201, including the echo’s distinctive wow-  
and flutter-induced wavering and the compressed sound obtained with magnetic saturation.  
The Mode Selector carries on the tradition of the RE-201, offering twelve different  
reverberation effects through various combinations of the three playback heads and reverb.  
You can set delay times with the TAP input pedal and use an expression pedal (sold  
separately) for controlling parameters.  
Equipped with a “Virtual Tape Display,” which produces a visual image of a running tape.  
About COSM (Composite Object Sound Modeling)  
Composite Object Sound Modeling—or “COSM” for short—is  
BOSS/Roland’s innovative and powerful technology that’s used  
to digitally recreate the sound of classic musical instruments and  
effects. COSM analyzes the many factors that make up the original  
sound—including its electrical and physical characteristics—and  
creates a digital model that accurately reproduces the original.

INPUT Jacks  
EXP Pedal Jack  
(INPUT A/MONO, B)  
Connect an optional expression pedal (such as the  
Roland EV-5) to this jack.  
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.  
Once connected, the pedal can be used to control  
the repeat rate and intensity in real time.  
“Control Using an Expression Pedal” (p. 16)  
“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.  
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.  
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 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.  
When connected to both A/MONO and B, a ste-  
reo effect can be obtained when reverb is applied.  
If you are using the RE-20 in mono, connect to  
the A/MONO jack only.

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 last.  
When powering down: Turn off the power to your guitar amp first.  
• 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 power-  
up is required before the unit will operate normally.

Operating the RE-20  
Control Using an Expression Pedal  
You can control the following functions with an expression pedal (Roland EV-5; sold  
separately) connected to the EXP PEDAL jack on the rear panel.  
REPEAT RATE: The echo interval becomes shorter as the toe of the expression  
pedal is pressed further.  
In Long mode, the range for the Repeat Rate setting is twice that of  
Normal mode.  
INTENSITY:  
The Intensity increases as the toe of the expression pedal is pressed  
further, increasing the volume of the echo repeat sound (the  
feedback volume).  
ECHO LEVEL:  
This controls the level input to the echo. The volume of the echo  
sounds increases as the toe of the expression pedal is pressed further.  
* This function can be controlled only with an expression pedal.  
* The input level to the reverb is not changed.  
TWIST:  
Repeat Rate and Intensity are controlled simultaneously.  
In addition, this controls the ECHO VOLUME according to the  
echo level.  
As you further press down on the toe of the expression pedal, the  
echo sound starts to oscillate, then the oscillation rate increases  
and the pitch of the oscillation sound rises.  
The Repeat Rate and Intensity are set to the minimum value when the heel of the pedal  
is pressed down; when you press firmly on the toe of the pedal, the value changes to  
the value that’s been set with the knob.  
With the twist effect, the value that’s been set with the knob is obtained when the heel  
of the pedal is pressed down; when you press firmly on the toe of the pedal, the value  
changes to the maximum value.  
Expression pedal

About the Roland SPACE ECHO RE-201  
The Roland SPACE ECHO RE-201 is a reverb-equipped tape echo that debuted in 1974.  
About the Configuration of the Tape Echo/Reverb  
The tape echo section features an erase head, record head, and three playback heads  
arranged sequentially at equal intervals, such that a sound is played back three times  
at equal intervals.  
The three playback heads are switched with the MODE SELECTOR knob, making it  
possible to create different variations (patterns) of echo intervals.  
The reverb section is equipped with a spring reverb. The reverb signal path is  
connected in parallel to the tape echo section.  
Changing of the Echo Sound’s Pitch When  
REPEAT RATE is Changed  
Turning the REPEAT RATE knob to the right (clockwise) gradually increases the tape  
speed. As this happens, sounds are played back more closely together, and the pitch  
begins to rise.  
Simultaneously, the density of the sounds during recording gradually decreases, so  
when those sounds reach the playback heads, the pitches that were raised then begin  
to fall.  
Oscillation in the Tape Speed  
Even without any change in the REPEAT RATE knob setting, the tape speed is always  
changing slightly due to the resistance from mechanical friction, tape slippage, and  
other factors.  
This creates oscillations in the pitch of each of the three echo sounds, automatically  
producing the RE-201’s characteristic chorus effect.  
About the Change in Sound Quality with Magnetic Saturation  
Due to magnetic saturation, recording to and playing back from tape produces a sense  
of compression in the sound, giving it a characteristic warmth that is unique to tape.  
In addition, the sonic quality of playback and recording also changes with the change  
in tape speed.  
About the Reverb  
The RE-201’s reverb section includes three springs arranged in a “Z” formation. The  
vibration of each spring influences the motion of the others to produce the reverb’s  
characteristic sound.

Troubleshooting  
Power doesn’t come on  
Is the guitar or keyboard connected correctly  
to the INPUT A/MONO jack?  
Are the INTENSITY knob and INPUT  
VOLUME knob positioned correctly?  
Check the connections again (p. 7–p. 11).  
Sounds may become distorted with the knob at  
certain settings. Turn down the INTENSITY  
knob and INPUT VOLUME knob to an  
appropriate level. If in spite of these measures  
the sound is still distorted, lower the output  
level of the device connected to the INPUT jacks.  
*
The power will not turn on without a plug  
connected to the INPUT A/MONO jack.  
Have the batteries run down?  
Replace them with new batteries (p. 6).  
*
The batteries included with the RE-20 are meant only  
to confirm that the unit is functional at the factory.  
Echo sounds not cancelled even  
when effect is switched off  
*
To reduce battery consumption, be sure to  
disconnect the plug connected to the INPUT A/  
MONO jack whenever the unit is not in use.  
Do you have a long delay time set?  
Try turning the ECHO VOLUME knob  
completely to the left (counterclockwise); this  
allows you to cancel the continuing sounds.  
Is the specified AC adaptor (PSA series; sold  
separately) connected correctly?  
Never use any AC adaptor other than the  
adaptor specified.  
Is the Intensity turned up?  
Try turning the INTENSITY knob or ECHO  
VOLUME knob completely to the left  
(counterclockwise); this allows you to cancel  
the continuing sounds.  
No sound/Volume is low  
Sounds output even with no  
sound input  
Is the other equipment connected correctly?  
Check the connections again (p. 7–p. 11).  
Is the Intensity setting turned up?  
With higher Intensity settings, even when no  
sounds are being input, the repeat sound  
in the sound may occur.

Sample Settings  
AMBIENCE  
This sound adds a sense of  
space using a short delay and  
reverb.  
RICH ECHO  
This is a sumptuous sound  
with a rich reverb added to  
the delay. This produces an  
even greater effect when  
played back in stereo.  
MULTI SLAP  
Effective with muting  
techniques for giving the  
sound a prominent contour.  
This is even more effective  
with phrases timed to the  
repeat sound.  
SPACE  
Connecting an expression  
pedal and using the pedal to  
control the intensity in real  
time allows you to produce  
even more fantastic sounds.  
To make this setup effective,  
set the INTENSITY knob at a  
position between three  
o’clock and maximum.
