Manuale utente del pedale boost Armor Buffer serie Dr.J JOYO D57

1. Introduzione

The JOYO Dr.J Series D57 Armor Buffer Boost Pedal is designed to enhance your electric guitar's signal integrity and provide an adjustable boost. This pedal combines two essential functions: a buffer to prevent signal degradation over long cable runs or complex pedalboards, and a booster to increase your signal level for solos or to drive your amplifier harder.

The buffer circuit actively maintains your guitar's original tone and dynamic range, ensuring that your sound remains clear and vibrant throughout your effects chain. The integrated boost function offers up to 20 dB of clean gain, allowing for precise volume adjustments or dynamic emphasis.

Equipped with True Bypass switching, the D57 ensures that your signal remains unaffected when the pedal is disengaged, preserving your instrument's natural tone.

Controlli e Connessioni:

• Manopola GAIN: This control adjusts the output level of the boost function. Turning it clockwise increases the boost level, providing up to 20 dB of additional gain.
• Pedale BOOST: Engages or disengages the boost effect. When engaged, the pedal's boost circuit is active, and the GAIN knob setting is applied.
• IN Buffer: The input buffer circuit. It receives the signal from your guitar or the preceding pedal in your chain, optimizing it for the effects chain.
• OUT Buffer: The output buffer circuit. It sends the processed signal to your amplifier or the next pedal, ensuring a strong and clear signal delivery.
• Nel Jack: 1/4-inch mono input jack for connecting your guitar or the output of another effect pedal.
• FUORI Jack: 1/4-inch mono output jack for connecting to your amplifier or the input of another effect pedal.
• Ingresso 9 V CC: Ingresso di alimentazione per un alimentatore da 9 V CC (centro negativo).

3. Impostazione

3.1 Requisiti di alimentazione

The D57 pedal requires a 9V DC power supply with a minimum current output of 800mA. The power supply connector must be center negative. Ensure you use a compatible power supply to prevent damage to the unit.

Nota: A power supply is not included with the pedal and must be purchased separately.

3.2 Collegamento del pedale

1. Collega la tua chitarra elettrica al IN jack of the D57 pedal using a standard 1/4-inch instrument cable.
2. Collegare il FUORI jack of the D57 pedal to the input of your amplifier or the next pedal in your effects chain using another 1/4-inch instrument cable.
3. Connect a compatible 9V DC center negative power supply to the Ingresso 9 V CC jack. The pedal will power on automatically.

Ensure all connections are secure before operating the pedal.

4. Istruzioni per l'uso

4.1 Buffer Function

The buffer circuit of the D57 pedal is always active when the pedal is powered on. Its primary role is to maintain the strength and clarity of your guitar signal, especially when using long cables or a large number of true bypass pedals. The IN Buffer optimizes the signal entering your effects chain, and the OUT Buffer ensures a robust signal is sent to your amppiù vivace.

4.2 Funzione boost

The boost function provides an additional gain stage to increase your signal level. This is useful for:

• Incrementoasing volume for solos to stand out in a mix.
• Driving the input of an amplifier or another overdrive/distortion pedal for more saturation.
• Compensating for signal loss in complex setups.

To use the boost function:

1. Imposta il GUADAGNO knob to your desired boost level. Start with the knob at a lower setting and gradually increase it.
2. Premere il tasto AUMENTO footswitch to engage the boost effect. The LED indicator (if present, not explicitly mentioned but common) will illuminate.
3. Premere il tasto AUMENTO footswitch again to disengage the boost effect.

Experiment with the GAIN knob to find the optimal boost level for your playing style and setup.

4.3 Vero bypass

The D57 pedal features True Bypass switching. This means that when the boost effect is disengaged, the pedal's circuitry is completely removed from your signal path, ensuring that your guitar's tone remains pure and unaltered. The buffer circuit, however, remains active to maintain signal integrity.

5. Manutenzione

• Pulizia: Utilizzare un panno morbido e asciutto per pulire l'esterno del pedale. Evitare detergenti abrasivi o solventi, poiché potrebbero danneggiare la finitura.
• Magazzinaggio: Conservare il pedale in un ambiente asciutto, lontano da temperature estreme, umidità e luce solare diretta.
• Energia: Disconnect the power supply when the pedal is not in use for extended periods to prolong its lifespan.
• Connessioni: Periodically check all cable connections for wear and tear. Replace damaged cables to ensure optimal performance.

6. Risoluzione Dei Problemi

• Nessun suono:
  • Assicurarsi che l'alimentatore sia collegato correttamente e funzioni.
  • Check all instrument cables for proper connection and integrity.
  • Verify your guitar's volume and tone controls are not set to zero.
  • Conferma il tuo amplifier is powered on and its volume is audible.
• Weak Signal or Tone Loss:
  • The D57's buffer is designed to prevent this. If experiencing issues, check cable quality and length.
  • Ensure the GAIN knob is set appropriately if the boost is engaged.
• Rumore/ronzio indesiderato:
  • Utilizzare un alimentatore CC da 9 V regolato e di alta qualità, progettato specificamente per i pedali per chitarra.
  • Assicurarsi che tutti i cavi siano schermati e in buone condizioni.
  • Keep the pedal away from sources of electromagnetic interference (e.g., power transformers, fluorescent lights).
