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 Dual Switch Pedal on
. A dual switch pedal must be wired as shown below. Any other wiring
pattern will not work correctly.
Continuous Control and Half Damper 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:
