A friend has a Hemingway DP-501 mark 1 digital piano where the metal plug came away from the plastic body, on the wire from the pedal board. The pedals are switches, not continuous controllers like more advanced units. I used a multimeter to figure out the wiring. With my dyscalculia it took over an hour to do this, checking and double checking. Then I soldered in a new plug. I made a table of the pin-outs which might be helpful to someone else 🙂
| Pedal (Position) | Function | Wire Colour | DIN Pin |
|---|---|---|---|
| Left | Soft | Red | 2 |
| Middle | Sostenuto | White | 4 |
| Right | Sustain | Green | 3 |
| – | Common (GND) | Brown | 1 |
It is not a bad piano at all, certainly good enough for kids to learn piano with dynamics and a decent sound if you turn up the treble. But the action is a bit clunky compared to similarly priced Casio models that are without the big speakers.
