1. Introduktion
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.

5. Opsætning og installation
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 Ledningsforbindelser
Før du foretager nogen tilslutninger, skal du frakoble bilens negative batteripol.
- Strøm og jord:
- Tilslut GND terminal to a clean, solid chassis ground point in the vehicle.
- Tilslut 12V terminal to a constant 12V power source from the vehicle's battery, preferably through a fused connection.
- Fjerntænding:
- If using the XLOC88X to turn on an amplifier, tilslut amplifier's remote input to the REM UD terminal of the XLOC88X.
- De 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.
- Indgange på højttalerniveau:
- 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.
- RCA udgange:
- Tilslut RCA-kabler fra CH1/2 to CH7/8 RCA Outputs on the XLOC88X to the corresponding RCA inputs on your aftermarket amplifier(e).
- Fjernniveau kontrol:
- Connect the included remote level control to the FJERN port on the XLOC88X. Mount the remote control in an accessible location for the user.
6. Betjeningsvejledning
Once installed, configure the XLOC88X settings for optimal audio performance.
6.1 Første opsætning og justeringer
- Tænd tilstand:
- Indstil Tænd tilstand 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).
- Jordisolering:
- If you experience noise (e.g., engine whine), adjust the Jordisolering switch. Start with GND, then try ISO, og endelig 200Ω to find the setting that minimizes noise.
- Indlæs Vælg:
- De Indlæs Vælg 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, eller 20KΩ to match your factory system's requirements.
- Inputtilstand:
- Indstil Inputtilstand skifte til 8CH if you are using all 8 speaker level inputs. Set to 4CH if you are only using 4 inputs and want to sum them to 8 outputs.
- LPF (lavpasfilter):
- If connecting to a subwoofer amplifier, you may activate the LPF switch to filter out high frequencies.
- Boost:
- De Boost switch provides a 0dB or 12dB bass boost. Use sparingly to avoid distortion.
- Forstærkningsjustering:
- With the factory stereo volume set to about 75% of maximum, slowly increase the Gevinst controls on the XLOC88X until the corresponding Klip indicator just begins to flash. Then, back off slightly until the clip indicator no longer illuminates. This ensures a clean, undistorted signal to your amplivligere.
- Adjust the gain on your aftermarket amplifier(s) according to their respective manuals, using the clean signal from the XLOC88X.
- Fjernniveau kontrol:
- The remote level control allows for convenient adjustment of the output level from the XLOC88X, typically used for subwoofer level control.
7. Vedligeholdelse
The NVX XLOC88X requires minimal maintenance to ensure long-term performance.
- Rensning: Use a soft, dry cloth to wipe the unit. Do not use harsh chemicals or abrasive cleaners.
- Tilslutningstjek: Kontrollér regelmæssigt alle ledningsforbindelser for at sikre, at de er fastgjorte og fri for korrosion.
- Miljø: Ensure the mounting location remains dry and free from excessive heat or vibration.
8. Fejlfinding
If you encounter issues with your XLOC88X, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| No power to XLOC88X | Incorrect 12V or GND connection; Blown fuse. | Check 12V and GND wiring. Verify fuse in 12V line. |
| Ingen lydudgang | Incorrect speaker level input wiring; RCA output not connected; Gain set too low; Incorrect Turn On Mode. | Verify all input/output connections. Check gain settings. Ensure XLOC88X is powered on and Turn On Mode is correct. |
| Forvrænget lyd | Gain set too high (clipping); Factory stereo output too high; Incorrect Load Select. | Reduce XLOC88X gain until clip indicator stops flashing. Adjust factory stereo volume. Experiment with Load Select settings. |
| Engine whine or noise | Ground loop; Poor ground connection; Signal interference. | Adjust Ground Isolation switch (GND, ISO, 200Ω). Ensure a clean, solid ground connection. Reroute signal cables away from power cables. |
| Factory stereo shuts off or reduces volume | Incorrect Load Select setting. | Adjust Load Select switches (20Ω, 60Ω, 20KΩ) to find the optimal setting for your factory stereo. |
