4.2.1 Collegamento di alimentazione
- Connect the power cable (typically red) from the amplifier's +12V terminal to the positive terminal of the vehicle's battery.
- Install the fuse holder within 18 inches (45 cm) of the battery and insert the appropriate fuse (refer to specifications for fuse rating).
4.2.2 Collegamento a terra
- Connect the ground cable (typically black) from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis.
- Ensure the ground point is free of paint, rust, or dirt for a good electrical connection. The ground cable should be as short as possible, ideally less than 3 feet (1 meter).
4.2.3 Remote Turn-On Connection
- Connect the remote turn-on wire (typically blue) from the ampterminale REM del lifier all'uscita remota dell'unità principale. Questo filo trasforma il amplifier on and off with your car's audio system.
4.2.4 Input Connection (RCA or Speaker Level)
- Ingresso RCA: Se l'unità principale ha uscite pre-out RCA, collegarle a amplifier's RCA INPUT terminals (CH-1(L) and CH-2(R)).
- Ingresso livello altoparlante: If your head unit does not have RCA pre-outs, use the speaker level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding wires on the amplifier's speaker level input harness.
4.2.5 Collegamento degli altoparlanti
- Collega il/i tuo/i subwoofer al/i amplifier's SPEAKER OUTPUT terminals.
- Ensure correct polarity (+ to + and - to -) for optimal sound performance.
4.2.6 Remote Bass Control (Optional)
- If using an optional remote bass control, connect it to the REMOTE BASS CONTROL port on the amppiù vivace.
5. Istruzioni per l'uso
Una volta installato, regolare il ampimpostazioni del filtro per prestazioni audio ottimali.
5.1 Controlli e regolazioni
- GUADAGNO: This control matches the output level of your head unit to the input sensitivity of the amplifier. Start with the gain set to minimum, then slowly increase it until you achieve a clear, undistorted sound at your desired maximum volume from the head unit. Avoid setting the gain too high, as this can introduce distortion.
- LP FILTER (Low Pass Filter): Questo controllo imposta il limite di frequenza superiore per il amplifier's output. For subwoofers, set this to a frequency typically between 50Hz and 120Hz. This ensures that only low-frequency sounds are sent to the subwoofer, improving overall sound clarity.
- EQUALIZZAZIONE DEI BASSI: This control provides a bass boost at a specific frequency. Use sparingly and adjust carefully to avoid distortion or damage to your subwoofer.
- REMOTE BASS CONTROL: If connected, this allows for convenient adjustment of the bass level from the driver's seat.
6. Manutenzione
- Pulizia: Pulire periodicamente il ampl'esterno del filtro con un panno morbido e asciutto. Non utilizzare prodotti chimici aggressivi o detergenti abrasivi.
- Verifiche della connessione: Regularly inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Sostituzione fusibile: Se il amplifier stops working, check the fuse in the external fuse holder. Replace it only with a fuse of the exact same type and rating. Never use a higher-rated fuse.
