Controlling the knob parameters using an expression pedal (EXP FUNCTION)

You can control the rotary speaker rotation speed as well as the LEVEL, DRIVE and BALANCE settings with a separately sold expression pedal (such as a Roland EV-30 or EV-5) that you’ve connected to the SPEED jack.

You can set the respective values for when the expression pedal is at MAX position (pressed down firmly with your toes) and at MIN position (pressed down firmly with your heel), and make continuous changes.

With the factory settings, the rotation speed of the rotary speaker can be controlled by the expression pedal.

Follow the steps below to change the parameter that’s controlled by the expression pedal.

  1. Turn off the RT-2 (unplug the cable from the INPUT A (MONO) jack).
  2. Turn the [FAST] knob to the maximum (MAX) setting.
  3. Turn all other knobs besides the [FAST] knob to the minimum (MIN) setting.
  4. Set the [MODE] switch to the “III” position.
  5. Turn on the power by connecting a plug to the INPUT A (MONO) jack while holding down the pedal switch.
  6. The CHECK indicator blinks, and the unit enters settings mode.
  7. Use the [DRIVE] knob to select the parameter to assign to the expression pedal.
  8. The VIRTUAL ROTOR display changes according to the parameter selected.
  9. Virtual rotor (red) display

    (factory setting)

    Controls the rotation speed of the rotary speaker.

    • When you press down on the expression pedal with your heel, the value changes until it reaches the setting of the [SLOW] knob; and when you press down on the expression pedal with your toes, the value changes until it reaches the setting of the [FAST] knob.
    • The CHECK indicator lights up orange while the expression pedal is controlling the rotation speed.
  10. Use the [SLOW] knob to set the minimum value that’s reached when you press the expression pedal with your heel.
  11. This can’t be set if you’ve selected the rotation speed of the rotary speakers in step 6.
  12. Use the [FAST] knob to set the maximum value that’s reached when you press the expression pedal with your toes.
  13. This can’t be set if you’ve selected the rotation speed of the rotary speakers in step 6.
  14. Press the pedal switch.
  15. The CHECK indicator rapidly blinks red, and the expression pedal parameter settings are stored in memory.
  16. The device can be used normally after around 2–3 seconds.

 

NOTE

Under the following conditions, the pedal switch only works as the effect on/off switch, regardless of the action of the pedal switch you set.
