NVX XLOC88X User Manual

1. Introducció

The NVX XLOC88X is an 8-channel high voltage active line output converter designed to integrate aftermarket amplifiers with factory car stereo systems. This device converts high-level speaker outputs from a factory head unit into low-level RCA signals, suitable for aftermarket amplifiers. It features impedance matching, noise isolation technology, and enhanced output controls to maintain audio quality and provide a clean signal to your amplifier. The XLOC88X allows for system upgrades without replacing the factory stereo, preserving original vehicle features such as large touchscreens, Bluetooth, Apple CarPlay, and Android Auto.

2. Informació de seguretat

• CH1+ to CH8- Speaker Level Inputs: Connects to the factory stereo's speaker wires.
• Turn On Mode Switch: Selects how the unit turns on (DC Offset, Audio Detection, or Remote Input).
• Ground Isolation Switch: Helps eliminate ground loop noise (GND, ISO, 200Ω).
• Load Select Switches (CH1-CH4, CH5-CH8): Adjusts the impedance load presented to the factory stereo (20Ω, 60Ω, 20KΩ).
• Interruptor de mode d'entrada: Selects between 8-channel or 4-channel input configuration.
• LPF Switch (Low Pass Filter): Activates or deactivates a low-pass filter.
• Interruptor de reforç: Provides a bass boost (0dB or 12dB).
• Gain Controls (CH1/2, CH3/4, CH5/6, CH7/8): Adjusts the output level for each pair of RCA channels.
• Indicadors de clip: LEDs that illuminate when the output signal is clipping, indicating distortion.
• Port de control de nivell remot: Connects the included remote level control.
• CH1/2 to CH7/8 RCA Outputs: Low-level audio outputs to connect to aftermarket ampaixecadors.

5. Configuració i instal·lació

Careful planning and execution are essential for optimal performance and safety.

5.1 Mounting the XLOC88X

• Choose a secure, dry location away from direct heat or moisture. Ensure adequate ventilation.
• Use the provided mounting screws to secure the unit.

5.2 Connexions de cablejat

Abans de fer qualsevol connexió, desconnecteu el terminal negatiu de la bateria del vehicle.

1. Energia i terra:
   • Connecteu el GND terminal to a clean, solid chassis ground point in the vehicle.
   • Connecteu el 12 V terminal to a constant 12V power source from the vehicle's battery, preferably through a fused connection.
2. Encès remot:
   • If using the XLOC88X to turn on an amplifier, connectar el amplifier's remote input to the REM FORA terminal of the XLOC88X.
   • El REM IN terminal is optional. If your factory stereo has a remote output, connect it here. Otherwise, the XLOC88X can generate a remote output based on DC offset or audio detection.
3. Entrades de nivell d'altaveu:
   • Carefully identify the positive (+) and negative (-) speaker wires from your factory stereo for each channel you intend to use (up to 8 channels).
   • Connect these wires to the corresponding CH1+ to CH8- terminals on the XLOC88X. Ensure correct polarity.
4. Sortides RCA:
   • Connect RCA cables from the CH1/2 to CH7/8 RCA Outputs on the XLOC88X to the corresponding RCA inputs on your aftermarket amplificador(s).
5. Control de nivell remot:
   • Connect the included remote level control to the COMANDAMENT port on the XLOC88X. Mount the remote control in an accessible location for the user.

6. Instruccions de funcionament

Once installed, configure the XLOC88X settings for optimal audio performance.

6.1 Initial Setup and Adjustments

1. Mode d'activació:
   • Estableix el Activa el mode switch based on your vehicle's factory stereo:
   • DC: Detects a DC offset on the speaker outputs when the stereo turns on.
   • AUD: Detects audio signal on the speaker outputs.
   • REM: Uses a traditional 12V remote turn-on signal from the factory stereo (connected to REM IN).
2. Aïllament del sòl:
   • If you experience noise (e.g., engine whine), adjust the Aïllament del sòl switch. Start with GND, then try ISO, i finalment 200Ω to find the setting that minimizes noise.
3. Selecció de càrrega:
   • El Selecció de càrrega switches (for CH1-CH4 and CH5-CH8) adjust the impedance presented to the factory stereo. This can prevent the factory stereo from detecting an open circuit and shutting off or reducing output. Experiment with 20Ω, 60Ω, o 20 KΩ to match your factory system's requirements.
4. Mode d'entrada:
   • Estableix el Mode d'entrada canviar a 8 canals if you are using all 8 speaker level inputs. Set to 4 canals if you are only using 4 inputs and want to sum them to 8 outputs.
5. LPF (filtre de pas baix):
   • If connecting to a subwoofer amplifier, you may activate the LPF switch to filter out high frequencies.
6. Impuls:
   • El Impulsar switch provides a 0dB or 12dB bass boost. Use sparingly to avoid distortion.
7. Ajust de guany:
   • With the factory stereo volume set to about 75% of maximum, slowly increase the Guanyar controls on the XLOC88X until the corresponding Clip indicator just begins to flash. Then, back off slightly until the clip indicator no longer illuminates. This ensures a clean, undistorted signal to your ampmés viu.
   • Adjust the gain on your aftermarket amplifier(s) according to their respective manuals, using the clean signal from the XLOC88X.
8. Control de nivell remot:
   • The remote level control allows for convenient adjustment of the output level from the XLOC88X, typically used for subwoofer level control.

7. Manteniment

The NVX XLOC88X requires minimal maintenance to ensure long-term performance.

• Neteja: Use a soft, dry cloth to wipe the unit. Do not use harsh chemicals or abrasive cleaners.
• Comprovacions de connexió: Inspeccioneu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
• Medi ambient: Ensure the mounting location remains dry and free from excessive heat or vibration.
