NVX XFLOC4 4-Channel Line Output Converter Instruction Manual

1. Introduction

The NVX XFLOC4 is a 4-channel adjustable line output converter designed to integrate aftermarket amplifiers with factory car audio systems. This device converts high-level speaker signals from your vehicle's factory stereo into low-level RCA signals, which are required by most aftermarket amplifiers.

It features an integrated digital noise filter to ensure clear audio reproduction and a DC amplifier turn-on trigger for convenient system activation. This manual provides detailed instructions for the proper installation, operation, and maintenance of your NVX XFLOC4 to ensure optimal performance and longevity.

2. Key Features

• 4-Channel Conversion: Converts speaker-level signals to RCA line-level signals for up to four channels.
• Integrated Digital Noise Filter: Reduces unwanted interference for enhanced sound clarity.
• Adjustable 3:1 Step-Down Output: Allows precise tuning of output levels (up to 160W maximum input).
• DC Amplifier Turn-On Trigger: Provides a remote turn-on signal for external amplifiers.
• Low Distortion Design: Engineered for clear, high-quality sound reproduction.

3. Setup and Installation

Proper installation is crucial for the performance of your NVX XFLOC4. If you are unsure about any steps, it is recommended to consult a professional car audio installer.

3.3 Connection Steps

1. Disconnect Vehicle Battery: Before starting any wiring, disconnect the negative terminal of your vehicle's battery to prevent electrical shorts.
2. Identify Speaker Wires: Locate the speaker wires from your factory stereo or amplifier. You will need to identify the positive (+) and negative (-) wires for each of the four channels (Front Left, Front Right, Rear Left, Rear Right). Refer to your vehicle's service manual or a reliable wiring diagram for accurate identification.
3. Connect Speaker Inputs: Connect the corresponding speaker wires from your vehicle to the input wires of the XFLOC4's harness. Ensure correct polarity (positive to positive, negative to negative).
   • Typically, solid colors are positive, and striped colors are negative, but this can vary. Always verify.
4. Connect Power and Ground:
   • Connect the +12V (Red) wire from the XFLOC4 harness to a switched +12V power source in your vehicle.
   • Connect the Ground (Black) wire from the XFLOC4 harness to a solid chassis ground point. Ensure a clean, secure connection.
5. Connect Remote Turn-On Output: Connect the Remote (Blue) wire from the XFLOC4 harness to the remote turn-on input of your aftermarket amplifier. The XFLOC4 will generate a turn-on signal for your amplifier when it detects an audio signal.
6. Connect RCA Outputs: Connect the RCA output cables from the XFLOC4 to the corresponding RCA inputs on your aftermarket amplifier (e.g., Front Left RCA to Front Left input on amp, etc.).
7. Secure Wiring: Ensure all connections are secure and properly insulated using wire nuts, electrical tape, or heat shrink tubing. Route wires away from moving parts and heat sources.
8. Mount the XFLOC4: Mount the XFLOC4 unit in a secure, dry location, away from excessive heat or moisture.
9. Reconnect Battery: Once all connections are verified, reconnect the negative terminal of your vehicle's battery.

4. Operating Instructions

After successful installation, the NVX XFLOC4 requires minimal operation. The primary adjustment is setting the output level to match your amplifier's input sensitivity.

4.1 Adjusting Output Levels

The XFLOC4 features individual adjustment potentiometers (small screws) for each channel (Left, Right, Rear Left, Rear Right) on the unit. These allow you to fine-tune the signal level sent to your amplifier.

1. Start with the adjustment screws turned fully counter-clockwise (minimum output).
2. Turn on your car audio system and play a familiar piece of music at a moderate volume.
3. Slowly turn the adjustment screws clockwise for each channel until you achieve a clean, undistorted sound from your amplifier. Avoid turning them up too high, as this can introduce distortion.
4. Adjust your amplifier's gain settings according to its manufacturer's instructions, ensuring that the amplifier is not clipping (distorting). The XFLOC4's output should be set to provide a strong, clean signal to the amplifier without overdriving it.

The integrated digital noise filter operates automatically to minimize interference, contributing to the overall clarity of your audio system.

5. Maintenance

The NVX XFLOC4 is designed for reliable, long-term operation with minimal maintenance.

• Periodic Inspection: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
• Cleaning: If necessary, gently wipe the exterior of the unit with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
• Environmental Protection: Ensure the unit remains in a dry environment, protected from extreme temperatures and direct sunlight.
