3.1 manopole di controllo
- si fondono: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is controlled by the Drive knob, allowing for fine-tuning of the blend ratio.
- Livello: Imposta il volume di uscita complessivo del pedale.
- Guidare: Controls the amount of gain in the overdriven signal.
- Basso: Adjusts the level of the low frequencies.
- Medi bassi: Adjusts the level of the low-mid frequencies. The center frequency can be switched between 500 Hz and 1 kHz.
- Ciao medi: Adjusts the level of the high-mid frequencies. The center frequency can be switched between 1.5 kHz and 3 kHz.
- Alti: Adjusts the level of the high frequencies.
Interruttori 3.2
- Cambio di attacco: Modifies the treble content of the overdriven signal. Options are Boost, Flat, and Cut.
- Cambio grugnito: Modifies the low-end content of the overdriven signal. Options are Thin, Raw, and Fat.
- Lo Mids Switch: Selects the center frequency for the Lo Mids knob (500 Hz or 1 kHz).
- Interruttore dei medi alti: Selects the center frequency for the Hi Mids knob (1.5 kHz or 3 kHz).
- Interruttore di sollevamento a terra: Disconnects the ground from the XLR output to help eliminate hum or ground loops when connected to external equipment.
3.3 Connessioni
- Input (1/4" Jack): Connect your bass guitar or other instrument here.
- Output (1/4" Jack): Connect to your bass amplifier o altri pedali per effetti.
- Direct Output (XLR): Provides a balanced output for connecting directly to a PA system, mixing console, or audio interface.
- Parallel Output (1/4" Jack): Outputs the unaffected input signal, useful for parallel processing or sending a clean signal to another device.
- Ingresso 9 V CC: Connect a regulated 9V DC power supply (center negative, minimum 30mA).
4. Impostazione
- Ensure the pedal is powered off before making any connections.
- Collega il tuo basso al Ingresso jack sul lato destro del pedale.
- Collegare il Produzione jack on the left side to your bass ampcontributo del lificatore.
- If using the balanced output, connect the Direct Output (XLR) to a PA system, mixing console, or audio interface.
- If you need an unaffected signal, connect the Uscita parallela su un altro dispositivo.
- Connect a regulated 9V DC (center negative) power supply to the Ingresso 9VDC. The pedal requires a minimum of 30mA. Note: A power supply is not included with the pedal.
- Once all connections are secure, you can power on the pedal.
5. Istruzioni per l'uso
5.1 Funzionamento di base
To activate the pedal, press the footswitch. The LED indicator will illuminate. To bypass the effect, press the footswitch again.
5.2 Tone Shaping
- Start with all EQ knobs (Low, Lo Mids, Hi Mids, Treble) at the 12 o'clock position for a flat response.
- Regolare il Guidare knob to achieve your desired level of overdrive. Higher settings will produce more distortion.
- Utilizzare il Miscela knob to mix the clean signal with the overdriven signal. This allows you to retain clarity and low-end presence while adding grit.
- Sperimenta con il Attacco E Grugnito switches to fine-tune the treble and bass characteristics of the overdriven tone.
- Utilize the 4-band EQ to sculpt your overall tone. The Lo Mids E Ciao Mids switches allow you to select different frequency centers for precise control.
- Regolare il Livello knob to match the output volume with your bypassed signal or to boost your signal for solos.
6. Manutenzione
- Mantenere pulito il pedale pulendolo con un panno morbido e asciutto. Evitare l'uso di detergenti abrasivi o solventi.
- Protect the pedal from extreme temperatures, moisture, and direct sunlight.
- Assicurarsi che tutti i cavi siano in buone condizioni e correttamente collegati per evitare perdite o danni al segnale.
- Always use a regulated 9V DC center-negative power supply to avoid damage to the unit.
7. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun suono | Incorrect power supply; cables not connected properly; pedal bypassed. | Verify 9V DC center-negative power supply is connected. Check all input/output cables. Ensure pedal is engaged (LED illuminated). |
| Ronzio o rumore eccessivo | Ground loop; faulty cables; interference from other equipment. | Coinvolgere il Sollevamento a terra switch on the XLR output. Try different cables. Ensure power supply is isolated and free from noise. Move pedal away from power transformers or other noisy electronics. |
| Weak or distorted signal (unintended) | Guadagno errato staging; faulty instrument cable. | Regolare Livello E Guidare knobs. Test with a different instrument cable. |
