Making Connections

Your RP-3 can be connected in several different ways to meet the requirements of specific applications. The following diagrams offer some

different ways your RP-3 can be connected.

RP-3 into two 2X12 Combo Amplifiers

For those of you out there that feel that “bigger is better”, this set-up should work quite nicely for you. First plug into the input of the RP-3.
Connect both RP-3 outputs into the inputs of both of the amplifiers. Using a set-up such as this will let you produce guitar tones with lots of

Running Direct into a Mixer

The RP-3 provides you with a Cabinet Emulator for running direct to a mixing board.

A set-up such as this, will give you the ability to run directly to the mixing/recording board. To help ensure great recording tones, use the
Speaker Cabinet emulator that is located in the RP-3. The first thing you will want to do when using this set-up is, first run into the Input of the
RP-3. Then run out of both of the Outputs into 2 inputs on the mixing board and pan each channel hard left and hard right. Now to use the
Cabinet emulator, simply press the <Edit> button and then use the Parameter select buttons to move you through the Effects matrix until you
reach the Cabinet emulator effect. The Parameter select buttons and the Value buttons will help you fine-tune the Cabinet emulator.

Section 3 - Basic Operations

About the RP-3’s Modes

The RP-3 offers several modes, allowing easy operation of the Effects and Parameters. The modes are as follows:

PROGRAM MODE

Allows you to scroll through the 30 Factory and 30 User Programs by using the Value <UP> and <DOWN> buttons as well as the <UP>
and <DOWN> foot switches. Select Program mode from Bank mode by pressing the <2> and <3> foot switches simultaneously until the
Program Mode LED lights and a P appears briefly in the display window. Foot switches <1-3> act as on/off toggle switches for the specified

effects.

BANK MODE

Allows you to scroll quickly through Factory and User Banks by using the <UP> and <DOWN> foot switches. Select Bank mode by pressing
the <2> and <3> foot switches 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 display
window, you can also use the Value <UP> and <DOWN> buttons to scroll through Programs and Banks.

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 foot switches <1-3> will begin flashing,
indicating that you can choose a Program in the selected Bank by pressing one of the three foot switches. Once a program number has been
selected, both the Bank and Program numbers will be displayed.

EDIT MODE

Allows you to modify effect Parameters in a program. Enter Edit mode by pressing the <Edit> button. 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 buttons.
The Parameter Select <UP> and <DOWN> buttons allow you to scroll through the vertical effect LEDs, while the <LEFT> and <RIGHT>
buttons allow you to scroll through the horizontal parameter LEDs.

After selecting a Parameter, you can change its value with the Value <UP> and <DOWN> buttons. When changing Parameter values, a
decimal point will begin flashing in the lower right corner of the display when the value shown is not the stored value for the program. 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.

STORE MODE

Once you have modified the Parameters and Effects, you can store them to a User Program location. When Effects or Parameters have changed
in a Program, the decimal point in the lower right corner of the display will flash, indicating a change and you need to store the changes. Press
the <Store> button once and the both of the seven segment LEDs in the display window will flash. Select the User bank and program
location you want using the Value <UP> and <DOWN> buttons and press the <Store> button again to save the changes.

RP-3

Section - 3 Basic Operations

BYPASS MODE

Allows you to bypass the RP-3’s Effects. Enter this mode by pressing footswitches <1 & 2> simultaneously and BY 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-3 will default
to the last mode you were in.

TUNER MODE

Allows you to tune your guitar. Enter Tuner mode by pressing and holding footswitches <1 & 2> simultaneously. Now tu 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 vertical effects matrix LEDs (tuning bar) will light. Once
the green LED on the tuning bar is lit, the note is in tune. If the note is not in tune, 1 or 2 of the LEDs above or below the green IN TUNE LED
will be lit. If LED’s below are lit, the note is flat and should be tuned up. If the LEDs above are lit, the note is sharp and should tuned down.
You can change your tuning preference by using the Value <UP> and <DOWN> buttons while in Tuner mode. The default factory setting is:
40 A=440 Hz. The tuning reference control ranges from 27 (427) Hz to 53 (453) Hz, which is the equivalent of ± 50 cents (1/2 semitone)
in either direction form 440 Hz.

When you scroll down from 27 (427) Hz, you will also find alternate dropped tunings. Alternate tunings are A = Ab ((ab), A = G (g), and A

= Gb (gb). The display window will briefly flash the currently selected tuning preference.

Exit this mode by pressing any one of the footswitches. When you exit this mode, the RP-3 will default to the last mode you used.

LEARN-A-LICK MODE

The Learn-A-Lick function allows you to record a 12 second passage of music and play it back as slow as 1/4 speed with no change in pitch.
This is very useful for picking out the notes of a fast solo passage.
There are 3 functions for Learn-A-Lick. They include:

• Start / Stop

• Rewind

• Record

Using Learn-A-Lick

• Connect the headphone output of your CD or tape player to the Jam-a-long input jack on the rear panel using an 1/8” stereo plug. Set the
level to a desired listening level using the CD or tape player volume control.

• Press the <UP> and <DOWN> footswitches simultaneously to enter Learn-a-lick mode.

• Cue up to the passage you want to record and hit pause on the CD or tape player.

• Release the pause button and press the <3> foot switch together when you are ready to begin recording the passage. The display will
read: rE and recording will begin. When recording is completed, the phrase is set into an auto-loop playback mode. Stop or press
pause on the CD or Tape player.

• Pressing the <TEMPO DN> foot switch will slow the playback down to 1/4 speed in 1/8th speed intervals.

• Pressing the <TEMPO UP> foot switch will increase the playback speed to normal speed at 1/8th speed intervals.

• Pressing the <REWIND> foot switch steps back through the loop at 1 second intervals.

• The Expression pedal will control output level of auto loop.

• To re-record a passage, press the <RECORD> foot switch again.

• To exit the Learn-A-Lick mode, press the <UP> and <DOWN> footswitches simultaneously.

Ambience, or reverberation, is produced when sound energy is reflected off room surfaces and objects. Using reverb 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:

Reverb Turns the Reverb effect on or off.

Type Allows you to choose your ambience or setting you want to use. There are ten available type settings:

CL=Club HA=Hall

St=Studio Ch=Church
ro=Room Ar=Arena
PL=Plate Sp=Spring
gA=Garage

Level Controls the amount of reverb signal to be mixed in with the dry signal. Ranges from 0 to 99.

Decay Time The amount of time it takes for the Reverb to fade to inaudibility. Ranges from 1 to 10.

The RP-3’s programmable Speaker Cabinet circuitry allows you to use it in both recording and live situations without lugging heavy amps
and/or cabinets around. Just connect the RP-3’s outputs to a mixing console and kick in the Speaker Cabinet. Parameters are as follows:

Cabinet Turns the Cabinet Emulator on or off.

Type Selects the tonal characteristics of the simulated cabinet. There are 9 different cabinet types; 1 being the

brightest and 9 being the darkest.

Note: When headphones are plugged in, the Speaker Cabinet Emulator is engaged globally on all programs. This will affect the

sound at the left and right main outputs.
