2. Configuración e instalación
Una instalación correcta es crucial para un rendimiento óptimo y la seguridad. Se recomienda que la instalación la realice un profesional cualificado.
2.1 Conexiones de energía
- Potencia (B+): Connect a heavy-gauge wire directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Ensure an inline fuse (not supplied) is installed within 18 inches of the battery.
- Tierra (GND): Conecte un cable de calibre grueso desde el ampConecte el terminal GND del voltímetro a una superficie metálica limpia y sin pintar del chasis del vehículo. El punto de tierra debe ser lo más corto posible.
- Remoto (REM): Connect a wire from the vehicle's head unit's remote output to the ampTerminal REM del lificador. Esto activa el ampEncendido y apagado del amplificador con la unidad principal.
2.2 Conexiones de entrada de audio
- Entrada RCA: Conecte los cables RCA desde el preamplificador de su unidad principal.amp salidas a la ampLas tomas de entrada RCA del amplificador. amplifier features buffered pre-amp input circuitry.
- Salidas de línea RCA: Full range RCA line outputs are provided for daisy-chaining additional ampsalvavidas.
2.3 Conexiones de salida de los altavoces
- Conecte su(s) subwoofer(es) a la amplifier's speaker output terminals. The QB1500D is a mono amplifier designed for subwoofer applications. Ensure the total impedance of the connected speakers is within the amplifier's rated specifications (2 Ohm stable).
- El amplifier uses direct-connect integrated speaker wire terminals.
2.4 Fusión
El amplifier uses ATC type fuses. The recommended fuse configuration is 4 x 20 amp fuses, totaling 80 amps. Always replace fuses with the same type and rating.
3. Instrucciones de funcionamiento
The QB1500D amplifier ofrece varios controles para ajustar su sistema de audio.
- Control de nivel de entrada: This variable control matches the amplifier's input sensitivity to the output level of your head unit. Start with the control at minimum and slowly increase until desired volume is achieved without distortion.
- Cruce de paso bajo (LPF): The continuously variable 12dB low-pass crossover allows you to set the upper frequency limit for the amplifier's output, typically used to send only low frequencies to subwoofers.
- Refuerzo de graves: A continuously variable 12dB bass boost at 45Hz allows for enhancement of low-frequency output. Use this feature judiciously to avoid distortion or damage to speakers.
- Filtro subsónico: The continuously variable subsonic filter (15-55Hz) removes extremely low frequencies that are inaudible but can waste amplifier power and damage subwoofers. Adjust this to protect your subwoofers from over-excursion.
- Bass Remote Capability: El amplifier supports an optional bass remote (sold separately) for convenient level adjustment from the driver's seat.
4. Mantenimiento
The Quantum QB1500D ampEl lifier está diseñado para un funcionamiento confiable con un mantenimiento mínimo.
- Limpieza: Limpie periódicamente el ampLimpie el exterior del elevador con un paño suave y seco. Evite el uso de productos químicos agresivos o limpiadores abrasivos.
- Gestión del calor: The QSINK heat management system is designed to dissipate heat efficiently. Ensure the amplifier is installed in a location with adequate airflow and is not covered or obstructed. Overheating can lead to thermal shutdown and reduced performance.
- Conexiones: Periodically check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can cause poor performance or damage.
5. Solución de problemas
Si tiene problemas con su amplifier, consulte los siguientes problemas y soluciones comunes:
- Sin energía:
- Check the inline fuse near the battery and the fuses on the ampmás duradero.
- Verify all power, ground, and remote connections are secure and have proper voltage.
- Sin salida de audio:
- Ensure RCA input cables are securely connected to both the head unit and the ampmás duradero.
- Verifique las conexiones del cable del altavoz para verificar que la polaridad sea la adecuada y el contacto sea seguro.
- Verify the head unit is powered on and outputting audio.
- Sonido distorsionado:
- Adjust the input level control to prevent clipping.
- Check speaker impedance to ensure it matches the ampcapacidades del generador.
- Ensure proper settings for the low-pass crossover, bass boost, and subsonic filter.
- Amplifier Overheating (Thermal Shutdown):
- Asegúrese de que haya una ventilación adecuada alrededor del ampmás duradero.
- Check speaker impedance; running below the minimum rated impedance can cause excessive heat.
- Reduce the input level or bass boost settings.
- DC Short Circuit Protection: El amplifier is equipped with DC short circuit protection. If this protection activates, the amplifier will shut down. Check all speaker wiring for shorts to ground or between positive and negative terminals.
