This unit features a 6:1 step-down ratio, adjustable gain output, and a DC amplifier turn-on trigger.

2. Principais características

• Operação em 4 canais: Supports front and rear speaker channels for comprehensive ampintegração do liffer.
• Adjustable Gain Output: Allows precise matching of the output signal to the amplifier's input sensitivity.
• High Power Input Capability: Handles up to 600 watts total (150 watts per channel) from the source unit.
• DC Amplifier Turn-On Trigger: Provides a remote turn-on signal for the amplifier, eliminating the need for a separate remote wire from the head unit.
• Low Distortion Design: Engineered for high-quality audio signal conversion with minimal distortion.

5.2 Etapas de conexão

1. Desconecte a bateria: Antes de começar, desconecte o terminal negativo da bateria do seu veículo para evitar curtos-circuitos.
2. Identify Speaker Wires: Locate the speaker output wires from your factory or aftermarket head unit. These will be connected to the input side of the XPLOC4's wiring harness.
3. Connect Speaker Inputs: Connect the corresponding speaker wires from your head unit to the input wires of the XPLOC4 harness. Match positive to positive and negative to negative for each channel (Front Left, Front Right, Rear Left, Rear Right).
4. Conexões de energia e aterramento:
   • Conecte o +12V (Yellow) wire from the XPLOC4 to a constant +12V power source.
   • Conecte o GND (preto) wire from the XPLOC4 to a solid chassis ground point.
5. Saída de ativação remota: The XPLOC4 provides a Remote (Blue) output wire. Connect this wire to the remote turn-on input of your aftermarket amplifier. This signal will turn on the amplifier when the head unit is active.
6. RCA Output Connections: Connect the RCA output cables from the XPLOC4 to the RCA input jacks on your aftermarket amplifier. Ensure Front Left/Right and Rear Left/Right channels are correctly matched.

6.1 Adjusting Gain Levels

The NVX XPLOC4 features adjustable gain controls for each channel pair (Front and Rear). These controls allow you to match the output level of the XPLOC4 to the input sensitivity of your amplifier, preventing distortion and optimizing sound quality.

1. Configuração inicial: Turn the gain adjustment screws on the XPLOC4 all the way down (counter-clockwise).
2. AmpGanho do lificador: Set the gain controls on your aftermarket amplifier to their minimum setting.
3. Volume da unidade principal: Turn your head unit volume up to about 75-80% of its maximum level.
4. Adjust XPLOC4 Gain: Slowly turn the gain adjustment screws on the XPLOC4 clockwise until the red LED indicator light just begins to flicker or illuminate steadily. This indicates that the signal is approaching clipping. Back off slightly until the LED is off or only flickers minimally.
5. Ajustar AmpGanho do lificador: Once the XPLOC4 gains are set, slowly increase the gain on your amplifier until the desired volume and sound quality are achieved without audible distortion.

The red LED indicator on the XPLOC4 serves as a clipping indicator. If it illuminates brightly or constantly, the input signal is too high, and distortion may occur. Reduce the head unit volume or the XPLOC4 gain until the LED is off or only flickers occasionally on peak notes.

7. Manutenção

The NVX XPLOC4 is designed for reliable operation and requires minimal maintenance. Ensure the unit is installed in a dry location, away from excessive heat and direct sunlight. Periodically check all wiring connections to ensure they remain secure and free from corrosion.

• Limpeza: Use um pano macio e seco para limpar a parte externa da unidade. Não use produtos químicos agressivos ou abrasivos.
• Ventilação: Ensure the unit has adequate ventilation to prevent overheating, although passive cooling is generally sufficient for this device.
