4.2 Procédure de montage

  1. Placez le amplifier in the desired mounting location and mark the positions for the mounting screws.
  2. Drill pilot holes if necessary, ensuring no wires or vehicle components are damaged.
  3. Sécuriser le amplifier using the provided mounting screws.

5. Connexions

5.1 Connexions d'alimentation et de mise à la terre

Proper power and ground connections are critical for ampPerformances et sécurité de l'amplificateur.

  • GND (Masse): Connect to a clean, unpainted metal surface of the vehicle chassis. The ground wire should be as short as possible (less than 3 feet) and of the same gauge as the power wire.
  • REM (Activation à distance) : Connect to the remote turn-on output of your head unit. This wire signals the ampL'amplificateur peut être allumé et éteint avec l'unité principale.
  • +BATT (12V Power): Connect directly to the positive terminal of the vehicle's battery. An in-line fuse holder with the appropriate fuse rating (typically 30A for TH90.2) must be installed within 18 inches of the battery.
  • FUSIBLE: Le amplifier includes an integrated fuse. Ensure it is correctly rated.

5.2 Connexions des enceintes

Connect your speakers to the SPEAKER terminals. Observe correct polarity (positive to positive, negative to negative).

  • Mode Stéréo: Connect left speaker to L+ and L-, right speaker to R+ and R-.
  • Mode ponté : For mono operation (e.g., a subwoofer), connect the speaker's positive terminal to R+ and the negative terminal to L-. Refer to the 'BRIDGE' markings on the amplifier.

5.3 Connexions d'entrée

The TH90.2 offers both low-level (RCA) and high-level inputs.

  • ENTRÉE DE LIGNE (RCA) : Connectez les câbles RCA à la sortie pré-enregistrée de votre autoradio.amp sorties vers le amplifier's LINE IN jacks.
  • HLI (High-Level Input): If your head unit does not have RCA outputs, use the provided high-level input connector. Connect your head unit's speaker wires to the HLI connector, observing polarity.
  • SORTIE LIGNE (RCA) : These outputs allow you to pass the audio signal to another amplifier dans un multi-ampsystème lificateur.

6. Commandes et réglages

Le TH90.2 amplifier features several controls for fine-tuning your audio system.

  • GAIN: Ce contrôle correspond à la amplifier's input sensitivity to the output level of your head unit. Start with the gain at minimum and slowly increase it until the sound is clear and undistorted at high volume levels from your head unit.
  • X-OVER (Crossover Switch):
    • HP (Passe-haut) : Allows frequencies above the set HPF point to pass through. Useful for full-range speakers to prevent low-frequency distortion.
    • COMPLET: Permet le passage de toutes les fréquences.
    • LP (Filtre passe-bas) : Allows frequencies below the set LPF point to pass through. Essential for subwoofers.
  • HPF (filtre passe-haut) : Adjusts the cutoff frequency for the high-pass filter (40Hz - 400Hz).
  • LPF (filtre passe-bas) : Adjusts the cutoff frequency for the low-pass filter (40Hz - 400Hz).

7. Mode d'emploi

Once all connections are made and verified, and initial gain settings are established:

  1. Mettez le contact de votre véhicule et allumez l'autoradio. amplifier's POWER indicator should illuminate.
