RP21D User’s Guide Section One - Introduction

Powering the RP21D

Once the audio connections have been made, connect the 4 pin connector of the power adapter to the power jack on the back of the RP21D and the other end to an AC outlet. Begin to play your guitar while adjusting the Input Level on the back panel of the RP21D. The Input Level should be adjusted so the clip LED lights occasionally on the strongest peaks of your signal.

At this point, turn the Output Level of the RP21D all the way down (counterclockwise). Then turn the power to your amplifier(s) on. Set the amp(s) to a clean setting and set the tone controls to a flat EQ response (on most amps, this would be 0 or 5 on the tone controls). Turn the Output Level of the RP21D up to achieve the desired volume level.

About the RP21D

Program Mode

When you first apply power to the RP21D, it will power up in Program mode. Program mode is indicated when the Program button is lit and is the mode used while you are performing. Using the footswitches while in Program mode allows you to access different Programs, turn effects on and off, access the tuner, bypass all effects, change banks, or adjust the values of any parameters assigned to the expression pedal. Rotating the Data Wheel selects Programs in the Program mode.

The Display

Understanding what the RP21D’s display is telling you is crucial to getting the most out of what the RP21D has to offer. There are several different sections to the display, and each section is telling you what the RP21D is currently doing, or listing options to alter the current sound.
