Configuració i instal·lació
Muntatge del Ampmés viu
The Reference-3004A amplifier features a compact footprint, allowing for flexible installation in various vehicles. Choose a mounting location that:
- Provides sufficient airflow for cooling.
- Is protected from direct sunlight, moisture, and excessive vibration.
- Allows for easy access to wiring connections and controls.
Assegureu-vos el amplifier using the provided mounting screws. Ensure the heat sink side (opposite the connections) is positioned to allow for optimal heat dissipation, especially if installing vertically.

Connexions de cablejat
Proper wiring is crucial for performance and safety. Refer to the diagram below for connection points.
Imatge: Una imatge detallada view of the rear panel of the Infinity Reference-3004A amplifier, highlighting the power, ground, remote, RCA input/output, and speaker wire terminals.
- Power (BATT +12V): Connect to the positive terminal of the vehicle's battery using an appropriate gauge power cable (e.g., 4-gauge or 8-gauge depending on total system power). Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Terra (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection. Use the same gauge wire as the power cable.
- Remot (REM): Connecteu-lo a la sortida d'encesa remota de la unitat principal. Aquest cable encén el ampencén i apaga l'activador amb el teu estèreo.
- Input (FRONT/REAR RCA): Connect to the RCA pre-out jacks of your aftermarket head unit. For factory radios without RCA outputs, use the included bare wire-to-RCA adapters with speaker-level inputs. The amplifier's Balanced Differential Inputs ensure low noise and distortion.
- Sortides dels altaveus: Connect your speakers to the appropriate terminals. This is a 4-channel amplifier, allowing for connection of four speakers. It can also be bridged for 2-channel operation to power subwoofers.
Circuit de protecció
The Reference-3004A includes on-board circuitry to protect against shorts, high-temperature, overvoltage, i undervoltage conditions. An LED indicator (PWR/PROT) is provided to signal when one of these conditions exists.
Instruccions de funcionament
After installation, adjust the ampConfiguració del lifer per a un rendiment d'àudio òptim.

- Ajust de guany: El control de guany coincideix amb el amplifier's input sensitivity to the output of your head unit. Start with the gain set to minimum (fully counter-clockwise). Play a dynamic piece of music at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back it off slightly.
- Crossover Settings (HPF/LPF/FULL): The Reference-3004A features variable electronic crossover circuits for precise tuning.
- HPF (filtre de pas alt): Allows frequencies above the set point to pass through. Useful for protecting full-range speakers from low bass frequencies.
- LPF (filtre de pas baix): Allows frequencies below the set point to pass through. Typically used when bridging the amplifier to power subwoofers.
- COMPLET: Disables the crossover, allowing all frequencies to pass.
- PWR/PROT LED Indicator: A green light indicates normal operation (Power). A red light indicates the amplifier is in protection mode due to a fault (Protection).
Manteniment
The Infinity Reference-3004A amplifier requires minimal maintenance.
- Mantenir el ampEl lificador està net i lliure de pols i restes. Feu servir un drap suau i sec per netejar-lo.
- Ensure all wiring connections remain secure. Periodically check for loose connections.
- Do not block the ventilation fins, as this can lead to overheating.
