4. Configurazione e installazione

Proper installation is crucial for optimal performance and safety. If you are not confident in performing the installation yourself, please seek professional assistance.

4.1. Posizionamento

The compact design of the NB-3000 allows for flexible placement. Common locations include:

• Under a car seat (ensure adequate clearance and ventilation).
• Nel bagagliaio.
• Behind a rear seat.

Secure the subwoofer firmly to prevent it from moving during vehicle operation. Use mounting brackets or straps if provided or necessary.

4.2. Collegamenti elettrici

Prima di effettuare qualsiasi collegamento, assicurarsi che il terminale negativo della batteria del veicolo sia scollegato.

1. Collegamento di alimentazione (BATT+): Connect a suitable gauge power cable (e.g., 8 AWG or 10 AWG, depending on cable length and power requirements) directly from the vehicle's positive battery terminal to the "POWER" terminal on the subwoofer's high-level input connector. Install an in-line fuse (e.g., 20A-30A) within 18 inches (45 cm) of the battery.
2. Collegamento a terra (GND): Connect a short, heavy gauge ground cable (same gauge as power cable) from the "GND" terminal on the subwoofer's high-level input connector to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical contact.
3. Accensione remota (REM): Connect a remote turn-on wire from your car stereo's remote output (usually a blue/white wire) to the "REM" terminal on the subwoofer's high-level input connector. This wire tells the subwoofer to turn on and off with your car stereo. If your stereo does not have a remote output, you may need to use an ignition-switched 12V source.
4. Ingresso audio:
   • Ingresso a basso livello (RCA): If your car stereo has RCA pre-outs, connect RCA cables from the stereo's subwoofer or rear pre-outs to the "CH1" and "CH2" RCA inputs on the subwoofer.
   • Input di alto livello: If your car stereo does not have RCA pre-outs, connect the speaker wires from your stereo's rear speakers to the "HIGH LEVEL INPUT" terminals on the subwoofer's connector. Ensure correct polarity (+ to + and - to -).
5. Controllo del livello a distanza: Connect the wired remote control cable to the "REMOTE" port on the subwoofer's control panel. Mount the remote control in a convenient location for the driver.

Dopo aver effettuato tutti i collegamenti, ricollegare il terminale negativo della batteria del veicolo.

5. Istruzioni per l'uso

Once installed, you can adjust the subwoofer's settings for optimal sound.

5.1. Accensione iniziale

Turn on your car stereo. The "POWER" indicator light on the subwoofer's control panel should illuminate (green). If the "PROTECT" light (red) illuminates, there may be a wiring issue or fault. Refer to the Troubleshooting section.

5.2. Regolazione dei controlli

• GUADAGNO (MIN/MAX): This knob controls the input sensitivity. Start with the GAIN set to minimum (MIN). Play music with a moderate bass level. Slowly increase the GAIN until the bass output blends well with your main speakers without distortion. Avoid setting the GAIN too high, as this can cause distortion and damage.
• FREQ (Frequenza): This knob adjusts the low-pass filter (LPF) crossover frequency, typically from 50Hz to 160Hz. The LPF ensures that only low frequencies are sent to the subwoofer. Adjust this to blend smoothly with your main speakers. A common starting point is around 80-100Hz.
• FASE (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Listen to music with strong bass and switch between 0° and 180°. Choose the setting that provides the most impactful and cohesive bass response.
• REMOTE (Level Control): The wired remote control allows you to conveniently adjust the subwoofer's output level from the driver's seat without accessing the main unit.

6. Manutenzione

The Peiying NB-3000 requires minimal maintenance.

• Mantenere l'unità pulita pulendola con un panno morbido e asciutto. Non utilizzare prodotti chimici aggressivi o detergenti abrasivi.
• Controllare periodicamente tutti i collegamenti elettrici per accertarsi che siano saldi e privi di corrosione.
• Ensure the area around the subwoofer is clear to allow for proper ventilation.
