Configuración e instalación
Unha instalación axeitada é crucial para un rendemento e unha seguridade óptimos. Recoméndase ter isto ampLiificador instalado por un profesional cualificado.
1. Montaxe do Ampmáis vivo
Escolla unha localización de montaxe seca, ben ventilada e protexida da luz solar directa ou da calor excesiva. Asegúrese de que haxa espazo suficiente arredor do amplifier for air circulation. Use the provided mounting hardware to secure the ampvidador firmemente.
2. Conexións de cableado
Ensure the vehicle's battery is disconnected before making any electrical connections.
- Conexión de alimentación (+12 V): Connect a suitable gauge power cable from the vehicle's positive battery terminal to the +12V terminal on the amplifier. An in-line fuse (not supplied) should be installed within 18 inches (45 cm) of the battery.
- Conexión a terra (GND): Connect a short, heavy-gauge ground cable from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis.
- Acendido remoto (REM): Conecta un cable de acendido remoto da saída remota da unidade principal ao terminal REM do amplifier. If your head unit does not have a remote output, the amplifier features an auto-sense turn-on mode (DC offset or Audio Sense) which can be selected.
- Conexións dos altofalantes: Conecta os teus altofalantes ao amplifier's speaker output terminals. Observe correct polarity (+ to + and - to -). The amplifier supports 4-channel stereo or 2-channel bridged configurations.
- Input Connections (RCA or High-Level): Conecta as saídas RCA da unidade principal ao amplifier's RCA input jacks. If your head unit lacks RCA outputs, use the supplied high-level input adapters to connect to your head unit's speaker outputs.

Controis operativos
The JBL CLUB-704 amplifier features various controls to fine-tune your audio experience. These controls are typically located under a removable panel for protection and a clean aesthetic.
Imaxe 2: Primeiro plano view da amplifier's control panel, showing adjustable settings for gain, crossover frequency (HPF/LPF/FULL), bass boost, phase, and turn-on mode.
- Input Level (HI/LO): Selects between high-level (speaker-level) or low-level (RCA) input signals.
- Control de ganancia (MÍN/MÁX): Axusta a sensibilidade de entrada do amplifier to match the output of your head unit. Start with minimum gain and slowly increase until desired volume is achieved without distortion.
- Crossover (X-OVER - HPF/LPF/FULL): Selects the type of filter for the output.
- HPF (filtro paso alto): Allows frequencies above the set point to pass through, ideal for full-range speakers.
- LPF (filtro de paso baixo): Allows frequencies below the set point to pass through, ideal for subwoofers.
- COMPLETO: Allows all frequencies to pass through, bypassing the crossover.
- Frecuencia (FREQ): Adjusts the cutoff frequency for the HPF or LPF, typically ranging from 32Hz to 320Hz.
- Bass Boost (0dB/12dB): Provides an adjustable bass boost at 45Hz to enhance low-frequency output.
- Phase (0°/180°): Adjusts the phase of the output signal, useful for optimizing bass response with subwoofers.
- Turn-On Mode (DC/REM): Selects how the ampo lifier acende.
- DC: Detects a DC offset on the high-level inputs to turn on the ampmáis vivo.
- REM: Uses a dedicated remote turn-on wire from the head unit.
Mantemento
To ensure long-lasting performance from your JBL CLUB-704 amplifer, siga estas sinxelas pautas de mantemento:
- Limpeza: Limpe regularmente o amplifier's exterior with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners.
- Ventilación: Asegúrese de que o amplifier's cooling fins are free from obstructions to allow proper heat dissipation.
- Conexións: Comprobe periodicamente todas as conexións do cableado para asegurarse de que estean ben fixadas e libres de corrosión. As conexións soltas poden provocar un rendemento deficiente ou danos.
- Substitución de fusibles: If a fuse blows, replace it only with a fuse of the same type and rating (30A). Using an incorrect fuse can damage the amplificador ou provocar un incendio.
Resolución de problemas
Se tes problemas co teu amplifier, refer to the following common troubleshooting steps before contacting support:
- Sen enerxía: Check the power, ground, and remote turn-on connections. Verify the in-line fuse near the battery and the fuses on the amplifier. Ensure the vehicle's battery has sufficient charge.
- Sen son: Check all RCA or high-level input connections. Verify speaker wiring for correct polarity and secure connections. Ensure the head unit is powered on and sending an audio signal. Adjust gain settings.
- Son distorsionado: Reduce the gain setting on the amplifier. Check for proper impedance matching with your speakers. Ensure speaker wires are not shorted.
- Ampsobrequecemento do lificador: Asegurar o amplifier has adequate ventilation and is not covered. Check speaker impedance to ensure it is within the amplifier's rated limits.
- Protection Light On (PWR/PROT): If the protection light is illuminated, the amplifier has detected an issue (e.g., short circuit, overheating, low voltage). Disconnect power, check all wiring, and allow the unit to cool down before reconnecting.
