2. Característiques del producte

• Integrated Power Supply and Tuner: Combines two essential pedalboard functions into a single unit, saving space and simplifying setup.
• Isolated 8-Channel DC 9V Output: Features 8 isolated outputs to prevent ground loops and noise. Two outputs provide 500mA for high-current digital effects, and six outputs provide 100mA for standard analog pedals.
• Low Noise Filtered Output: Designed with filtered outputs to ensure clean power delivery and minimize unwanted noise.
• Protecció contra curtcircuits i sobrecorrents: Each output is protected against short circuits and overcurrent conditions, safeguarding your pedals.
• True Bypass Tuner: The integrated tuner features true bypass wiring, ensuring that your instrument's tone remains unaffected when the tuner is disengaged.
• Pantalla LED gran: Provides a clear and easy-to-read display for tuning status.
• Construcció duradora: Housed in a robust aluminum-alloy casing with a stoving varnish finish for stability and longevity.

4. Configuració

Follow these steps to set up your JOYO Power Tune JF-18R pedal:

1. Connect Power to JF-18R: Connect the provided power adapter to the DC 9V input jack (IN) on the JF-18R pedal and plug the adapter into a standard AC outlet.
2. Connecteu l'instrument: Plug your guitar or bass into the 1/4-inch input jack (IN) on the right side of the JF-18R pedal.
3. Connecta't a Amplifier/Other Pedals: Connect the 1/4-inch output jack (OUT) on the left side of the JF-18R pedal to your amplifier or the input of your next effects pedal in the signal chain.
4. Power Your Pedals: Use the included DC power cords to connect your other effects pedals to the isolated DC 9V outputs on the top of the JF-18R. Ensure you match the current requirements (100mA or 500mA) of your pedals to the correct outputs.

5. Instruccions de funcionament

5.1. Funció d'afinador

To use the tuner function:

1. Press the footswitch (labeled "True Bypass") to engage the tuner mode. The LED display will activate.
2. Play a single note on your instrument. The display will show the detected note and indicate whether it is sharp, flat, or in tune.
3. Adjust your instrument's tuning until the display indicates the note is in tune (typically a stable green light or center indicator).
4. Press the footswitch again to disengage the tuner and return to true bypass mode, allowing your signal to pass through unaffected.

5.2. Power Supply Function

The JF-18R provides stable power to your effects pedals:

• El 500mA outputs are suitable for high-current digital pedals such as delays, reverbs, and multi-effects units.
• El 100mA outputs are ideal for most standard analog pedals like overdrives, distortions, and compressors.
• Always ensure the total current draw of your connected pedals does not exceed the maximum capacity of each output.
• Use the provided DC power cords and polarity reversing cable as needed for your specific pedals. Most pedals use center-negative polarity.

6. Manteniment

• Keep the pedal clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Do not expose the unit to excessive moisture, heat, or direct sunlight.
• Assegureu-vos que tots els cables estiguin connectats correctament per evitar problemes intermitents.
• Store the pedal in a safe place when not in use to prevent physical damage.

7. Solució De Problemes

• No Power to Pedals:
  • Ensure the main power adapter for the JF-18R is correctly connected and plugged into a working outlet.
  • Verify that the DC power cords connecting the JF-18R to your pedals are secure.
  • Check the current draw of your pedals and ensure they are connected to appropriate 100mA or 500mA outputs.
  • Test individual pedals with a known working power source to rule out pedal malfunction.
• Tuner Not Responding/Inaccurate:
  • Ensure your instrument is properly connected to the JF-18R's input.
  • Play single notes clearly and allow the tuner to register.
  • Check for any loose connections in your signal chain.
• Soroll/bruix no desitjat:
  • The JF-18R features isolated outputs to minimize noise. Ensure all pedals are connected to the isolated outputs.
  • Check for faulty cables or power adapters.
  • Ensure the power adapter for the JF-18R is a genuine JOYO adapter or a reliable alternative that meets specifications.
