4. Configuración e instalación
4.1 Localización de montaxe
Escolla un lugar de montaxe que estea seco, ben ventilado e seguro. Evite montar o amplifier directly on carpet or in enclosed spaces that restrict airflow. Common locations include under seats, in the trunk, or behind panels.
4.2 Procedemento de montaxe
- Coloca o ampo adaptador na localización de montaxe desexada e marque as posicións para os parafusos de montaxe.
- Drill pilot holes if necessary, ensuring no wires or vehicle components are damaged.
- Asegure o amplificador usando os parafusos de montaxe fornecidos.
5. Conexións
5.1 Power and Ground Connections
Proper power and ground connections are critical for amprendemento e seguridade do 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 (activación remota): Connect to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with the head unit.
- +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: O amplifier includes an integrated fuse. Ensure it is correctly rated.
5.2 Conexións de altofalantes
Connect your speakers to the SPEAKER terminals. Observe correct polarity (positive to positive, negative to negative).
- Modo estéreo: Connect left speaker to L+ and L-, right speaker to R+ and R-.
- Modo ponte: 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 ampmáis vivo.
5.3 Conexións de entrada
The TH90.2 offers both low-level (RCA) and high-level inputs.
- ENTRADA DE LIÑA (RCA): Conecte os cables RCA da toma de corrente da unidade principalamp saídas ao 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.
- SAÍDA DE LIÑA (RCA): These outputs allow you to pass the audio signal to another amplifier nun multi-ampsistema de eliminación.
6. Controis e axustes
The TH90.2 amplifier features several controls for fine-tuning your audio system.
- GAÑA: Este control coincide co 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 (Interruptor de división):
- HP (Paso alto): Allows frequencies above the set HPF point to pass through. Useful for full-range speakers to prevent low-frequency distortion.
- COMPLETO: Allows all frequencies to pass through.
- LP (Paso baixo): Allows frequencies below the set LPF point to pass through. Essential for subwoofers.
- HPF (filtro paso alto): Adjusts the cutoff frequency for the high-pass filter (40Hz - 400Hz).
- LPF (filtro paso baixo): Adjusts the cutoff frequency for the low-pass filter (40Hz - 400Hz).
7. Instrucións de funcionamento
Once all connections are made and verified, and initial gain settings are established:
- Acenda o contacto e a unidade principal do seu vehículo. O 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. Mantemento
The MTX Audio TH90.2 ampO lificador require un mantemento mínimo para garantir un rendemento a longo prazo.
- Limpeza: Limpar periodicamente o ampo exterior do lifador cun pano suave e seco. Non empregue produtos químicos agresivos nin produtos de limpeza abrasivos.
- Ventilación: Asegúrese de que o amplifier's heat sinks are free from obstructions to allow for proper airflow.
- Conexións: Comprobe ocasionalmente todas as conexións de alimentación, terra e altofalantes para asegurarse de que estean seguras e libres de corrosión.
