Figure 1 : Audio System HLC-2 Plus 2-Channel High-Low Converter. The image displays the main converter unit, a black rectangular box with a rotary knob for level adjustment (Min to Max) and a 'POWER' button. Two RJ-style cables with clear plastic connectors are shown connected to the unit, representing the wiring harness for signal input/output and remote turn-on.
The Audio System HLC-2 Plus is a 2-channel high-low converter designed to integrate aftermarket amplifiers with factory car stereos that lack RCA pre-outs. It converts high-level speaker signals into low-level RCA signals, providing a clean audio output for your amplifier. Key features include:
- Compatibility with all original OEM radios.
- 2-way high-low conversion with remote turn-on signal generation.
- Designed to prevent interference and turn-on noise.
- Excellent sound quality through PSA and 5-volt technology.
- Features a plug-in connection terminal for ease of installation.
- Fast and accurate music recognition.
5. Configuration et installation
5.1 Schéma de câblage (Général)
A detailed wiring diagram is crucial for correct installation. While specific diagrams may vary, the general connections are as follows:
- Entrée de haut niveau : Connect the speaker outputs from your factory radio to the high-level inputs of the HLC-2 Plus. Ensure correct polarity (positive to positive, negative to negative) for each channel.
- Sortie de bas niveau : Connect the RCA outputs from the HLC-2 Plus to the RCA inputs of your aftermarket amplifier.
- Allumage à distance : The HLC-2 Plus generates a remote turn-on signal. Connect this output to the remote input of your amplifier. This will turn on your amplifier automatically when the factory radio is powered on.
- Alimentation/Masse : The unit typically draws power from the high-level input signal, eliminating the need for a separate power wire. Ensure a good ground connection if specified by the manufacturer.
5.2 étapes d'installation
- Déconnecter la batterie : Débranchez toujours la borne négative de la batterie de votre véhicule avant d'entreprendre des travaux électriques.
- Access Speaker Wires: Locate and access the speaker output wires from your factory head unit or amplifier.
- Connect High-Level Inputs: Splice the factory speaker wires to the corresponding high-level input wires of the HLC-2 Plus. Use high-quality connectors or solder for secure connections.
- Connectez les sorties RCA : Run RCA cables from the HLC-2 Plus to your aftermarket amplifier.
- Connect Remote Wire: Connect the remote output wire from the HLC-2 Plus to the remote turn-on input of your amplifier.
- Monter le convertisseur : Securely mount the HLC-2 Plus in a dry, accessible location, away from heat sources and moving parts.
- Rebranchez la batterie : Une fois toutes les connexions vérifiées, rebranchez la batterie du véhicule.
6. Mode d'emploi
6.1 Mise sous tension initiale
After installation, turn on your vehicle's ignition and then the factory radio. The HLC-2 Plus should automatically detect the audio signal and send a remote turn-on signal to your amplifier, powering it on.
Réglage à 6.2 niveaux
The HLC-2 Plus features a rotary knob (Min-Max) for adjusting the output level. This allows you to match the output signal of the converter to the input sensitivity of your amplifier. Start with the knob at the minimum setting and gradually increase it while listening for distortion. Adjust until a clean, strong signal is achieved without clipping at the amplifier.
6.3 Bouton d'alimentation
The 'POWER' button on the unit is typically an indicator or a manual override. Refer to specific product documentation if its function deviates from automatic operation.
7. Entretien
- Veillez à ce que l'appareil reste propre et exempt de poussière et de débris. Utilisez un chiffon doux et sec pour le nettoyer.
- Ensure all wiring connections remain secure over time. Periodically check for loose connections.
- Avoid exposing the unit to direct sunlight or extreme heat, which can affect its lifespan.
- L'appareil ne contient aucune pièce réparable par l'utilisateur. N'essayez pas de l'ouvrir ou de le réparer vous-même.
8. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Aucun son de amplifier | Incorrect wiring; No remote signal; Amplifier not powered; HLC-2 Plus not receiving signal. | Check all wiring connections (high-level input, RCA output, remote). Ensure factory radio is on and producing sound. Verify ampConnexions d'alimentation et de mise à la terre de l'amplificateur. |
| Son déformé | Output level too high; Incorrect gain settings on amplifier. | Reduce the output level on the HLC-2 Plus. Adjust ampparamètres de gain du lificateur. |
| Ample lificateur ne s'allume pas | Remote wire not connected; HLC-2 Plus not detecting signal. | Verify remote wire connection from HLC-2 Plus to amplifier. Ensure factory radio is on and playing audio. |
| Engine noise/Whine | Ground loop issue; Poor wiring. | Ensure all components are properly grounded. Check for damaged or unshielded RCA cables. |
