NVX XLOC66X 6-Channel Line Output Converter

1. Introducción

The NVX XLOC66X is a high-voltage active line output converter designed to seamlessly integrate aftermarket amplifiers with factory car audio systems. Modern factory head units often lack RCA outputs, which are essential for connecting aftermarket amplifiers. This device converts high-level speaker signals from your factory stereo into low-level RCA signals, allowing for a clean and reliable connection to your amplifier. It features 6 input channels and 6 output channels, impedance matching, and a remote level control for enhanced audio system flexibility.

Please read this manual thoroughly before installation and operation to ensure proper use and optimal performance of your NVX XLOC66X.

2. Características principales

• 6-Channel Speaker Level Inputs: Accepts high-level signals from up to six speaker channels.
• 6-Channel RCA Outputs: Provides low-level RCA outputs for front, rear, and subwoofer ampconexiones más duraderas.
• Alto voltage Handling: Capable of handling up to 40V (400 watts RMS) speaker level inputs.
• Alto volumen de salidatage: Delivers up to 9.5 Volts of output for strong signal to ampsalvavidas.
• Encendido automático: Features automatic turn-on via DC offset detection or audio signal detection, eliminating the need for a dedicated remote wire from the head unit.
• Load Selection Switch: Adjustable impedance (20, 60, or 20K ohms) to prevent factory stereo shutdown issues.
• Control remoto con cable del nivel de graves: Included for convenient adjustment of subwoofer output level.
• LED Clip Indicator: Provides visual feedback for optimal gain setting and to prevent signal clipping.

3. Configuración e instalación

3.1 Precauciones de seguridad

• Always disconnect the vehicle's negative battery terminal before starting any electrical installation.
• Asegúrese de que todo el cableado esté adecuadamente aislado y asegurado para evitar cortocircuitos y daños.
• Consulte con un instalador de audio para automóvil profesional si no está seguro acerca de alguna parte del proceso de instalación.

3.2 Mounting the XLOC66X

Choose a secure, dry location for mounting the XLOC66X, away from excessive heat or moisture. Ensure adequate ventilation around the unit. Use the provided mounting screws to secure the device.

3.3 conexiones de cableado

The XLOC66X features a terminal block for power, ground, remote, and speaker level inputs, and RCA jacks for low-level outputs.

• 12 V (Alimentación): Connect to a constant 12V power source from the vehicle's battery. Use an appropriate gauge wire and an inline fuse (not included) near the battery.
• GND (tierra): Connect to a solid chassis ground point in the vehicle. Ensure a clean, paint-free metal-to-metal connection.
• REM IN (Remote Input): Connect to the remote turn-on output of your head unit if available. This is optional if using DC offset or audio detection for turn-on.
• REM OUT (Salida remota): Provides a 12V remote turn-on signal for your aftermarket amplizador(es).
• CH1+ to CH6+ (Speaker Level Inputs): Connect these terminals to the corresponding positive and negative speaker wires from your factory head unit or factory amplificador. Asegúrese de la polaridad correcta.
• RCA Outputs (Front, Rear, Sub): Conéctelos a las entradas RCA de su mercado de accesorios. amplifier(s) using high-quality RCA cables.
• Remote Bass Knob Input: Connect the wired remote bass level control to the dedicated port on the XLOC66X.

3.4 Ajustes y configuraciones iniciales

Before powering on, configure the switches on the XLOC66X:

• Turn-on Mode Switch: Seleccione entre DC (DC offset detection), Dólar australiano (audio signal detection), or movimiento rápido del ojo (remote wire input). Choose the mode that best suits your vehicle's factory system.
• Load Select Switch (CH1-CH4 & CH5-CH6): Adjust the impedance presented to the factory stereo. Options are 20 Ω, 60 Ω, o 20 kΩ. Start with 20KΩ if unsure, and adjust if the factory stereo exhibits shutdown issues.
• Interruptor de modo de entrada: Seleccionar 4 canales for 4-channel input or 6 canales for 6-channel input, depending on your factory system's output.
• Ground Isolation Switch: Las opciones son Tierra (common ground), YO ASI (isolated ground), or 200 Ω (200 ohm isolated ground). Use this to address ground loop noise or alternator hum. Start with GND and switch to ISO or 200Ω if noise is present.
• Interruptor LPF (filtro de paso bajo): Empezar a ON if you want the subwoofer output to have a low-pass filter applied, or APAGADO Si tu amplifier handles the LPF.
• Perilla de refuerzo: This controls the bass boost for the subwoofer output. Start at 0 dB y ajuste según sea necesario.
• Gain Knobs (Front, Rear, Sub): These adjust the output level of the XLOC66X. Start at minimum (MIN) and adjust carefully during the operating phase.

4. Instrucciones de funcionamiento

4.1 Setting Gains

Proper gain setting is crucial for optimal sound quality and to prevent distortion. The XLOC66X features LED clip indicators for each output channel (Front, Rear, Sub).

1. Turn the gain knobs on the XLOC66X to their minimum (MIN) position.
2. Turn the gain knobs on your aftermarket amplifier(s) to their minimum setting.
3. Play a test tone (e.g., a 0dB sine wave at 1kHz for full-range, or 50Hz for subwoofer) at about 75% of your head unit's maximum volume.
4. Slowly increase the gain knob on the XLOC66X for one channel (e.g., Front) until the corresponding LED clip indicator just begins to flicker. Then, back off slightly until the LED is off. Repeat for Rear and Sub channels.
5. Once the XLOC66X gains are set, proceed to set the gains on your aftermarket amplifier(s) according to their respective manuals, ensuring no clipping occurs at the ampLifier stage.

4.2 Using the Remote Bass Control

The included wired remote bass level control allows you to conveniently adjust the output level of the subwoofer channel from your listening position. Connect it to the 'REMOTE' port on the XLOC66X. Rotate the knob to increase or decrease the subwoofer output.

4.3 Bass Boost and Low Pass Filter

The LPF switch and Boost knob affect the subwoofer output. If your subwoofer amplifier has its own low-pass filter, it is generally recommended to set the XLOC66X LPF to OFF. Use the Boost knob to add a subtle bass enhancement if desired, but avoid excessive boosting which can lead to distortion.

5. Mantenimiento

The NVX XLOC66X requires minimal maintenance. Keep the unit clean and free from dust and debris. Periodically check all wiring connections to ensure they are secure and free from corrosion. Avoid exposing the unit to extreme temperatures or moisture.
