5. Connexions
5.1 Power and Ground Connections
Proper power and ground connections are critical for amprendiment i seguretat del lificador.
- GND (terra): 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 (encesa remota): Connecteu-lo a la sortida d'encesa remota de la unitat principal. Aquest cable indica el amplificador per encendre i apagar amb la unitat principal.
- +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: El amplifier includes an integrated fuse. Ensure it is correctly rated.
5.2 Connexions d'altaveus
Connect your speakers to the SPEAKER terminals. Observe correct polarity (positive to positive, negative to negative).
- Mode estèreo: Connect left speaker to L+ and L-, right speaker to R+ and R-.
- Mode pont: 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 ampmés viu.
5.3 Connexions d'entrada
The TH90.2 offers both low-level (RCA) and high-level inputs.
- ENTRADA DE LÍNIA (RCA): Connecteu els cables RCA des del pre-emissor de la unitat principalamp sortides al 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.
- SORTIDA DE LÍNIA (RCA): These outputs allow you to pass the audio signal to another amplificador en una multi-ampsistema de filtració.
6. Controls i ajustos
The TH90.2 amplifier features several controls for fine-tuning your audio system.
- GUANY: Aquest control coincideix amb el 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 (Pas alt): Allows frequencies above the set HPF point to pass through. Useful for full-range speakers to prevent low-frequency distortion.
- COMPLET: Allows all frequencies to pass through.
- LP (Pas baix): Allows frequencies below the set LPF point to pass through. Essential for subwoofers.
- HPF (filtre de pas alt): Adjusts the cutoff frequency for the high-pass filter (40Hz - 400Hz).
- LPF (filtre de pas baix): Adjusts the cutoff frequency for the low-pass filter (40Hz - 400Hz).
7. Instruccions de funcionament
Once all connections are made and verified, and initial gain settings are established:
- Engegueu l'encesa i la unitat principal del vehicle. El amplifier's POWER indicator should illuminate.
- Play a familiar audio track at a moderate volume.
- Adjust the gain control as described in Section 6 to achieve clear, undistorted sound.
- Fine-tune the crossover settings (HPF/LPF) to blend the amplifier's output with other speakers in your system.
- If the PROTECT indicator illuminates, refer to the Troubleshooting section.
8. Manteniment
The MTX Audio TH90.2 ampEl lificador requereix un manteniment mínim per garantir un rendiment a llarg termini.
