SECTION 1 - STARTUP
SUPPLYING POWER

Line Conditioning - The RP-6, like any piece of computer hardware,
is sensitive to voltage drops, spikes, and surges. Interference such as
lightning or power “brownouts” can seriously, and in extreme cases,
permanently damage the circuitry inside the unit. Here are some ways
to avoid this type of damage:
• Spike/Surge Suppressors - This is an inexpensive solution to all
but the most severe of AC line conditions. Surge protected
power strips usually cost only slightly more than unprotected
strips, making them a worthy investment for protection of all your
valuable gear.
• AC Line Conditioners - This is the best way to go for total protection from improper line voltages, albeit the more expensive
way. Line conditioners constantly monitor for excessively high or
low voltages and adjust accordingly, thus delivering consistent
power levels.
FRONT PANEL CONTROLS
The front panel controls and functions of the RP-6 are as follows (refer
to diagram):
Section 1 - Startup
6
RP-6 Owner’s Manual
1) Pedalboard - The RP-6’s pedalboard consists of six footswitches.
The two Mode footswitches to the right of the Parameter Matrix
allow you to change from Program mode to Bank mode by pressing the UP & DOWN footswitches simultaneously. When changing
modes, the appropriate LED will light to indicate whether you are in
Program mode or Bank Mode. In Program Mode, the <UP> and
<DOWN> footswitches allow you to move through Programs, while
the four main switches, labeled 1 - 4, act as toggle On/Off switches for Distortion, Modulation, Delay, and Reverb. In Bank mode,
the <UP> and <DOWN> footswitches allow you to move through
Banks, while the 1-4 footswitches are used to select Programs. If
footswitches 1 and 2 are pressed simultaneously, Tuner Mode will
be activated. If footswitches 3 and 4 are pressed simultaneously,
Bypass Mode will be activated.
2) Parameter Matrix - The Parameter Matrix consists of a group of
horizontal Effect LEDs and a second group of vertical Parameter
LEDs. The Effect LEDs are: Compressor, Distortion, Silencer,
Equalization, Speaker Cab, Wah Wah, Mod/Pitch, Dual Delay, and
Reverb. This matrix shows you exactly what Effects and Parameters
are in use.
3) Display Window - The display window shows all current operating
and programming information and is comprised of two parts: the
seven segment LED displays and the Signal, Clip, and Store indicator LEDs. The first numeric LED in the display window indicates
whether you are in a User (U) or Factory Bank (F). The second
indicates the Bank number currently in use, and the third indicates
which Program number is currently in use. These numbers change
as you scroll through the available Programs. The functions of the
Signal, Clip, and Store indicator LEDs are as follows:
• Signal - Indicates whether a signal is entering the RP-6.
• Clip - Indicates analog clipping in the RP-6. Digital clipping can
be detected when the third vertical LED from the top of the
Parameter Matrix flashes. Distortion may be heard in the output
signal if either analog or digital clipping occurs. If analog clipping occurs, check the Distortion On/Off levels. The levels may
need to be lowered to eliminate the problem. To reduce digital
clipping, the Master Volume and/or Effects levels should be
checked and adjusted accordingly. As always, let your ears be
the judge.
• Store - Lights when a Parameter has been changed in a
Program. When <STORE> is pressed once, the first seven segment LED in the Display window will flash. Once you have
selected the Bank and Program location where you want to store
your effects, press the <STORE> key again (see page 11, under
Edit Mode for further information on storing a Program).
Section 1 - Startup

4) Value, Store and Edit Keys - The Value <UP> and <DOWN> keys
allow you to scroll through the RP-6’s Programs, or change
Parameter values in Edit mode. The <STORE> key allows you to
store an edited Program in memory for later use. The <EDIT> key
allows you to edit the User and Factory Programs.
5) Parameter Select Keys -The <LEFT> and <RIGHT> Parameter
keys allow you to navigate the horizontal Effect LEDs of the
Parameter matrix. The <UP> and <DOWN> Parameter keys allow
you to navigate the vertical Parameter LEDs of the Parameter
matrix. These keys are only active in Edit mode.
6) Output Level - Controls the overall output level of the RP-6. Also
controls the overall level of the headphones.
7) Presence - Enhances the high frequency content of the overall
sound. This will affect all presets.
8) Continuous Control Pedal - This volume-type pedal allows realtime control over Parameters in the RP-6.

SECTION 2 - BASIC OPERATIONS
ABOUT THE RP-6 MODES
The RP-6 offers five modes, allowing easy operation of the Effects and
Parameters. The modes are as follows:
PROGRAM MODE
Allows you to scroll through the 40 Programs by using the <UP> and
<DOWN> Value keys as well as the <UP> and <DOWN> footswitches. Enter Program mode by pressing the <UP> and <DOWN>
footswitches simultaneously until the Program LED lights and a P
appears briefly in the display window. Footswitches 1-4 act as on/off
toggle switches for the specified effects. Exit Program mode by
changing to another mode.
BANK MODE
Allows you to scroll quickly through Banks without going through
every Program to get to the next Bank. Enter Bank mode by pressing
the <UP> and <DOWN> footswitches simultaneously until the Bank
LED lights and a B appears briefly in the display window. When you
enter Bank mode, the Bank and Program numbers from the previous
mode will be retained. When a Program number is displayed in the
third LED of the display window, you can use the Value <UP> and
<DOWN> keys to scroll through Programs and Banks. This works
exactly like Program mode.
When the <UP> and <DOWN> footswitches are used in Bank mode,
you will scroll through Banks only. When you change a Bank using
this method, the previous Program number is not displayed with the
new Bank. The LEDs above footswitches 1-4 will begin flashing, indicating that you can choose a Program in the selected Bank by pressing one of the four footswitches. Once a Program number has been
selected, both the Bank and Program numbers will be displayed. Exit
Bank mode by changing to another mode.
EDIT MODE
Allows you to change Effects and Parameters in a Program. Enter Edit
mode by pressing the <EDIT> key. The Display window now shows
the value of the Parameter indicated by the LEDs in the Matrix. You
can scroll through the Parameter matrix using the Parameter Select
keys. The <UP> and <DOWN> keys allow you to scroll through the
vertical Parameter LEDs, while the <LEFT> and <RIGHT> keys allow
you to scroll through the horizontal Effect LEDs.
After selecting a Parameter, you can scroll through its values with the
<UP> and <DOWN> Data keys. When moving through Parameter values, the decimal point next to the Parameter value will flash when a
stored value has been changed. If you return to the original value, the
decimal point will stop flashing. If you exit Edit mode after changing
the Parameters and then return to Edit mode, the last viewed
Parameter will be displayed.
Section 2 - Basic Operations
RP-6 Owner’s Manual

STORE MODE
Once you have modified the Parameters and Effects, you can store
them to a user Program location. When you change an Effect or
Parameter in a Program, the Store LED will light, indicating that you
have changed a Parameter and need to store the changes. Press the
<STORE> key once and the first seven segment LED in the Display
window will flash U. Select the Program and Bank you want to store
your changes to, and press the <STORE> key again to save the
changes. Exit this mode by pressing any footswitch or Value key.
BYPASS MODE
Allows you to bypass the RP-6’s Effects. Enter this mode by pressing
footswitches 3 & 4 simultaneously. BYP will appear in the display
window to indicate you are in Bypass mode. Exit this mode by pressing any of the footswitches. When you exit this mode, the RP-6 will
default to the last mode you used. Bypass is not available while in
Edit mode.w
TUNER MODE
Allows you to tune your guitar. Enter Tuner mode by pressing
footswitches 1 & 2 simultaneously. tun will appear briefly in the display window followed by --- to indicate that you are in Tuner mode. To
begin tuning play a note on your guitar (a harmonic at the 12th fret will
work best). The display window will show the note being played and
the horizontal Parameter Matrix LEDs just under the tuning bar will
light. Once the LED directly under the IN TUNE of the tuning bar is lit,
the note will be in tune. If the note is not in tune, 1 or 2 of the LEDs left
or right of the IN TUNE LED will be lit. If they are to the left, the note is
flat and should be tuned up. If the LEDs are to the right, the note is
sharp and should tuned down. You can change your tuning preference by using the value <UP> and <DOWN> keys. The default factory setting is : A=440 Hz. The tuning reference control ranges from 427
Hz to 453 Hz, which is the equivalent of ± 50 cents (1/2 semitone) in
either direction form 440 Hz.
When you scroll down from 427 Hz, you will also find alternate
dropped tunings. Alternate tunings are A = Ab (415), A = G (392),
and A = Gb (370). The display window will briefly flash the currently
selected tuning preference.
Exit this mode by pressing any of the footswitches. When you exit this
mode, the RP-6 will default to the last mode you used. Tuner is disabled in Edit mode.

The RP-6 offers a three band parametric equalizer with preset Q’s.
The center frequency of each band is adjustable along with its gain
(boost or cut).
High Q settings yield narrow bandwidth, where boost and cut have
minimal effect on adjacent frequencies of the program material. Low
Q settings affect a wider number of frequencies when the selected
band is boosted or cut.

Ambience, or reverberation, is produced when sound energy is
reflected off room surfaces and objects. Using reverberation in
recorded program material gives the listener a sense that the material
is being performed in an actual room or hall. It is this similarity to actual acoustic spaces that makes reverberation a useful tool in recorded
music. Reverb Parameters and their functions are as follows:
On / Off..........................Turns the Module on or off.
Type ..............................Allows you to choose your ambience or setting you want to use. There are ten available
type settings:
SPr=Spring
StU=Studio
pLa=Plate
Gar=Garage
sOU=Sound Stage
HAL=Hall
bAt=Bathroom
CHU=Church
CLU=Club
ArE=Arena
Level..............................Controls the amount of reverb signal to be
mixed in with the dry signal. Ranges from 0 to
100.
EQ Frequency ...............Adjusts the center frequency of the Reverb
EQ. Varies from .02 to 16 kHz.
EQ Gain.........................Allows you to increase and decrease the level
of the EQ frequency. Varies from -15 to 15 dB.
Decay Time ...................The amount of time it takes for the Reverb to
fade to inaudibility. Ranges from 1 to 10.
