Aux Input
The Aux Input allows you to connect an MP3 or CD player to the RP250 and jam with your favor-
ite artists. The signal from your MP3 or CD player is output through the left, right, and headphone
outputs of the RP250. To use the Aux Input, connect the headphone output of your MP3 or CD
player to the Aux Input on the rear panel of the RP250 using an 1/8" stereo cable, and press
play on your MP3 or CD player. Use the playing device’s volume control and the RP250’s Master
Level knob to balance the levels.
Expression Pedal
The Expression Pedal on the RP250 can be linked to control the RP250’s Volume, Wah, Wham-
my™, YaYa™, or almost any of the RP250’s other parameters in real time with your foot. When
a parameter has been linked to the Expression Pedal, a minimum (heel) and maximum (toe) value
can also be specified. Apply extra pressure to the toe of the Expression Pedal to activate the
V-switch, and the Expression Pedal switches between the linked parameter and the Wah. The
procedure for linking a parameter to the Expression Pedal is as follows:
1. Press either Edit button until the Expression row has been selected (indicated by the LED light-
ing on the Expression row).  appears in the display.
2. Rotate Knob2 until the desired parameter appears in the Display. See page 44 for a complete
list of parameters that can be linked to the Expression Pedal.
3. Rotate Knob3 to select the minimum (heel) value the assigned parameter will reach with the
Expression Pedal in the toe up position.
4. Rotate Knob 4 to select the maximum (toe) value the assigned parameter will reach with the
Expression Pedal in the toe down position.
5. Store your Expression Pedal assignment to your preset. See page 17 for more information on
the storing procedure.
