Switch Pedal Problems
If you are having problems with connecting or using a switch pedal, check if one of the
following might be the issue:
• Sustain or Sostenuto is stuck “on”. Be sure the pedal is plugged in before switching
on the power. Turn power off then on if necessary.
• The pedal is acting backwards (“on” when up instead of down). Power cycle the unit
making sure to NOT press on the pedal during startup.
• A dual switch pedal is not working correctly, see Connecting a Switch Pedal on page 2-6.
A dual switch pedal must be wired as shown below. Any other wiring pattern will not
work correctly.
Continuous Control Pedal Problems
The continuous control pedal must be wired to a single stereo 1/4-inch plug as follows:
• Wiper to Tip
• Top end of resistance element to Ring
• Bottom end of resistance element to Sleeve
These connections are shown schematically below:
