2. Instrucións de seguridade

• Desconecte sempre o terminal negativo da batería do vehículo antes de comezar calquera traballo eléctrico.
• Asegúrate de que todo o cableado estea correctamente colocado e fixado para evitar danos por bordos afiados ou pezas móbiles.
• Empregue cableado do calibre axeitado para as conexións de alimentación e terra, tal e como se especifica na sección de instalación.
• Instala o ampo refrigerador nun lugar que permita unha ventilación axeitada para evitar o sobrequecemento.
• Evite montar o amplifter en zonas expostas a humidade ou vibracións excesivas.
• Se non tes claro algún dos pasos de instalación, consulta cun instalador profesional de audio para automóbiles.
• Isto amplifier is equipped with 2-way protection circuitry. Do not attempt to bypass or modify these safety features.

3. Configuración e instalación

3.1 Montaxe do Ampmáis vivo

The Hifonics GE14004 amplifier is designed for surface mounting. Choose a secure location in your vehicle that is dry, well-ventilated, and protected from direct sunlight or excessive heat. Ensure there is sufficient space around the amplifier for air circulation to prevent overheating. Avoid mounting on carpeted surfaces that may restrict airflow.

3.2 Conexións de cableado

O cableado axeitado é fundamental para amplifier performance and safety. Refer to the diagrams below for correct connections.

3.2.1 Panel de entrada e control

Imaxe 2: Front panel of the Hifonics GE14004 amplifier, displaying RCA inputs (CH1-CH4), high-level inputs, gain level controls (LEVEL), mode switches (2CH, 4CH, FULL, HP, LP), crossover frequency adjustments (X-OVER), bass EQ, and subsonic filter controls.

• Entradas RCA: Conecta as saídas RCA da unidade principal ao amplifier's RCA inputs (CH1-CH4). The RCA Jacks allow for daisy-chaining multiple amplifiers without splitter cords.
• Entradas de alto nivel: If your head unit does not have RCA outputs, use the high-level inputs.
• Gain Control (LEVEL): Axusta a sensibilidade de entrada para que coincida coa saída da unidade principal.
• Interruptor de modo: Select between 2-channel or 4-channel operation.
• Crossover (X-OVER):
  • COMPLETO: Full range audio.
  • HP (Paso alto): Allows frequencies above the set point (40Hz-300Hz) to pass.
  • LP (Paso baixo): Allows frequencies below the set point (40Hz-300Hz) to pass.
• Ecualizador de graves: Adjusts bass boost.
• Filtro subsónico: Filters out ultra-low frequencies (10Hz-40Hz) that are inaudible and can damage subwoofers.
• Cambio de fase: Adjusts the phase from 0-180 degrees.

3.2.2 Panel de saída de alimentación e altofalantes

Imaxe 3: Rear panel of the Hifonics GE14004 amplifier, showing the power input terminals (GND, REM, +12V), the 60A fuse, and speaker output terminals (CH1-CH4, bridged options).

• GND (terra): Connect to a clean, unpainted metal surface of the vehicle chassis. Use a short cable of the same gauge as the power cable.
• REM (activación remota): Connect to the remote output of your head unit. This turns the ampacende e apaga o activador coa unidade principal.
• +12V (Potencia): Connect directly to the positive terminal of the vehicle's battery. Install an in-line fuse holder (not included) within 18 inches of the battery.
• Fusible: O amplifier includes a 60A fuse. Do not replace with a fuse of a different rating.
• Saídas de altofalantes: Connect your speakers to these terminals. The amplifier supports 2 Ohm stable operation. For bridged mode, refer to the markings on the ampmáis vivo.

4. Instrucións de funcionamento

After completing all wiring connections, double-check them before reconnecting the vehicle's battery.

1. Encendido inicial: Reconnect the battery. Turn on your head unit. The ampO adaptador debería acenderse, o que se indica cun indicador LED (se está presente).
2. Axuste de ganancia: Comeza co amplifier's gain control set to minimum. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the amplifier's gain until you hear distortion, then back off slightly. This sets the maximum clean output.
3. Configuración de cruce: Adjust the High Pass (HP) and Low Pass (LP) filters according to your speaker types and desired sound. For full-range speakers, use HP. For subwoofers, use LP.
4. Bass Boost and Subsonic Filter: Adjust these controls to fine-tune the bass response. Use the subsonic filter to protect subwoofers from damaging low frequencies.
5. Cambio de fase: Experiment with the phase shift (0-180 degrees) to achieve optimal bass integration with your other speakers.

5. Mantemento

• Limpeza: Limpar periodicamente o amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or solvents. Ensure ventilation fins are free from dust and debris.
• Conexións: Regularly check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Substitución de fusibles: If the fuse blows, replace it only with a fuse of the exact same rating (60A). A repeatedly blown fuse indicates a problem that requires professional diagnosis.
