5.2. Connexions de câblage
Ensure all power, ground, remote, and speaker wires are connected correctly and securely. Use the provided wiring harness and fuse.
- Power (RED +12V): Connect directly to the positive terminal of the vehicle's battery. Install the 25A fuse (included) as close to the battery as possible.
- Ground (BLACK GND): Raccordez-le à une surface métallique propre et non peinte du châssis du véhicule. Assurez-vous d'une connexion solide.
- Remote (BLUE REM): Connectez-le à la sortie de commande à distance de votre autoradio ou à une source 12V commutée.
- Speaker Outputs (FR+, FR-, FL+, FL-, RR+, RR-, RL+, RL-): Connect to your speakers according to their polarity. Refer to the diagram on the amplifier for correct channel assignments.
- Entrée audio RCA : Connectez les sorties RCA de votre autoradio à ampentrées RCA du lifier.

6. Fonctionnement
The NXL-N4 amplifier features adjustable controls to fine-tune your audio system.
6.1. Paramètres du crossover
Le amplifier includes selectable crossovers to optimize sound output for different speaker types:
- LPF (filtre passe-bas) : Allows only low frequencies to pass through, typically used for subwoofers.
- HPF (filtre passe-haut) : Allows only high frequencies to pass through, typically used for full-range or component speakers.
- COMPLET: Allows the full frequency range to pass through, suitable for full-range speakers without specific filtering.
Adjust the crossover switch according to your speaker configuration and desired sound profile.

6.2. Prenez le contrôle
The gain control matches the output voltage de votre autoradio à la sensibilité d'entrée de amplifier. Start with the gain set to minimum and slowly increase it until you achieve a clear, undistorted sound at your desired volume level. Avoid setting the gain too high, as this can lead to distortion and potential speaker damage.
7. Entretien
To ensure the longevity and performance of your DS18 NXL-N4 amplifier, follow these maintenance tips:
- Nettoyage: Essuyez périodiquement le ampl'extérieur de l'amplificateur avec un doux, damp tissu. Évitez d'utiliser des produits chimiques agressifs ou des nettoyants abrasifs.
- Relations: Regularly check all wiring connections for tightness and corrosion, especially in marine environments.
- Ventilation: Assurez-vous que le amplifier's cooling fins are free from obstructions to maintain proper heat dissipation.
