5. Configuració i instal·lació
Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Si no esteu segurs de cap dels passos a seguir, consulteu un instal·lador professional.
5.1. Muntatge del Ampmés viu
- Choose a mounting location that is dry, well-ventilated, and protected from physical damage.
- Assegureu-vos d'espai suficient al voltant de amplifier for proper airflow to the cooling system.
- Assegureu-vos el amplifier firmly to a solid surface using appropriate screws.
5.2. Connexions de cablejat
Follow the wiring diagram carefully for power, ground, remote, and speaker connections.

5.2.1. Connexió d'alimentació
- Connect a high-quality power cable (positive, red) from the vehicle's battery to the +12V terminal al amplifier. Install an appropriate fuse (max. 12 inches from the battery) in line with the positive cable.
- Connect a ground cable (negative, black) of the same gauge as the power cable from the GND terminal al amplifier to a clean, unpainted metal point on the vehicle's chassis. Ensure a good electrical connection.
- Connect a remote turn-on wire (blue, 18 AWG recommended) from your head unit's remote output to the REM terminal al amplificador. Aquest cable fa que el ampengegueu i apagueu l'activador amb la unitat principal.
5.2.2. Connexió d'entrada d'àudio
- Connecteu els cables RCA des del pre-emissor de la unitat principalamp outputs (Front and Rear) to the corresponding ENTRADA RCA jacks on the ampmés viu.
5.2.3. Connexió de sortida d'altaveus
- Connecteu els vostres altaveus al CONNECTOR DE SORTIDA terminals. Ensure correct polarity (+ to + and - to -).
- For 4-channel operation, connect each speaker to its dedicated channel.
- For bridged operation (e.g., 2-channel or 3-channel), refer to the specific bridging instructions provided in the full product manual or consult a professional. The HL 2000.4 supports bridging for increased power output to fewer channels.
6. Instruccions de funcionament
6.1. Engegada inicial
- After all connections are made and verified, reconnect the vehicle's battery.
- Engegueu la unitat principal. El amplifier's POWER indicator should illuminate. If the PROT (Protection) indicator lights up, refer to the troubleshooting section.
6.2. Ajust dels controls
- LEVEL (Gain): Start with the LEVEL control at minimum. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's LEVEL control until you hear distortion, then back off slightly. This sets the gain correctly, preventing clipping and maximizing sound quality.
- CROSSOVER (HPF/LPF):
- FLAT (Full Range): Use this setting if your speakers are designed to play the full audio spectrum or if you are using an external crossover.
- HPF (filtre de pas alt): Use for speakers that should only reproduce mid-range and high frequencies (e.g., component speakers, full-range speakers not intended for deep bass). This filters out low frequencies.
- LPF (Low-Pass Filter): Use for subwoofers, allowing only low frequencies to pass through.
- INTENSIFICACIÓ DELS SONS MÉS GREUS: Use this control sparingly to enhance bass frequencies. Excessive bass boost can lead to distortion and potential speaker damage.
7. Manteniment
- Mantenir el amplifier clean and free from dust. Use a soft, dry cloth for cleaning.
- Ensure that the ventilation openings are not blocked to maintain proper cooling.
- Comproveu periòdicament totes les connexions del cablejat per verificar si estan ben ajustades i si hi ha corrosió.
- No utilitzeu productes químics agressius ni netejadors abrasius a la ampmés viu.
