- Sense energia:
- Ensure the power supply meets the 9VDC, 300mA minimum, center-negative specification.
- Verify the power cable is securely connected to both the pedal and the power source.
- Prova amb una font d'alimentació diferent si està disponible.
- No Sound/Effect:
- Check all audio cables for proper connection and functionality.
- Ensure the pedal is engaged (Bypass footswitch).
- Verify the MIX knob is not set to fully dry (counter-clockwise).
- Confirm the PROG knob is set to a desired delay program.
- Unwanted Noise/Buzzing:
- Use an isolated power supply. Daisy-chain power supplies can introduce noise.
- Comproveu si hi ha bucles de terra a la cadena de senyals.
- Assegureu-vos que tots els cables estiguin blindats i en bon estat.
- Tone Alteration (Bypassed or Dry Signal):
- While the D1 is designed for high fidelity, some users may perceive subtle tonal changes depending on their specific amplifier and signal chain. Experiment with pedal order and buffer placement.
- Ensure the pedal is receiving adequate, clean power.
