Setup
The M-Audio SP-2 sustain pedal is designed for simple plug-and-play operation. Follow these steps for initial setup:
- Connect the Pedal: Locate the 1/4 inch sustain pedal input on your electronic keyboard, digital piano, synthesizer, or MIDI controller. Insert the 1/4 inch jack from the SP-2 pedal firmly into this input. The pedal features a 6-foot cable for flexible placement.

- Position the Pedal: Place the pedal on the floor in a comfortable position for playing. The underside of the pedal features specially designed rubber pads that grip the floor, preventing slippage during use.

- Adjust Polarity (if necessary): The M-Audio SP-2 includes a polarity switch located on the bottom of the pedal. If the sustain function behaves inversely (e.g., sustains when not pressed, or does not sustain when pressed), flip this switch to reverse the polarity. Some keyboards may require the keyboard to be powered off and on again after changing the polarity switch setting for the change to take effect.

Maintenance
The M-Audio SP-2 sustain pedal is built for durability and requires minimal maintenance. To ensure its longevity and optimal performance:
- Keep the pedal clean by wiping it with a soft, dry cloth.
- Avoid exposing the pedal to excessive moisture or extreme temperatures.
- Do not attempt to disassemble the pedal, as this may void the warranty.
Troubleshooting
If you encounter issues with your M-Audio SP-2 sustain pedal, consider the following common troubleshooting steps:
| Problem | Solution |
|---|---|
| Sustain function is reversed (e.g., sustains when not pressed, or does not sustain when pressed). | Locate the polarity switch on the bottom of the pedal and flip it to the opposite position. Power off and then power on your keyboard or instrument for the change to take effect. |
| Pedal slides on the floor during use. | Ensure the pedal is placed on a clean, dry surface. The rubber pads on the underside are designed to prevent slippage. If the surface is excessively smooth or dusty, clean it. |
| No sustain effect or intermittent sustain. | Check that the 1/4 inch jack is fully and securely inserted into the sustain input of your instrument. Try connecting the pedal to a different compatible instrument to rule out an issue with the instrument's input. |
