NVX XLCA2 X-Series 2-Channel Line Out Converter Instruction Manual

1. ആമുഖം

The NVX XLCA2 X-Series 2-Channel Line Out Converter is designed to seamlessly integrate aftermarket amplifiers, speakers, and subwoofers with your vehicle's factory car stereo system. Modern factory stereos often come with advanced features like large touchscreens, hands-free Bluetooth, Apple CarPlay, and Android Auto, making it undesirable to replace them. However, these factory units may not provide the necessary low-level RCA outputs or optimal bass response required for high-performance aftermarket audio components.

The XLCA2 addresses these challenges by converting high-level speaker signals from your factory head unit into clean, low-level RCA signals, while also restoring lost bass frequencies with its advanced xBOOST technology. This manual provides detailed instructions for setting up, operating, and maintaining your NVX XLCA2 to ensure optimal audio performance.

2 പ്രധാന സവിശേഷതകൾ

2.1 High-Power 2-Channel Line Out Converter

The NVX XLCA2 is a robust 2-channel line out converter capable of handling speaker-level inputs up to 400 watts RMS per channel. It efficiently converts these high-level signals to low-level RCA signals, making it compatible with a wide range of aftermarket amplifiers. This ensures a clean signal transfer without degradation, crucial for high-fidelity audio systems.

2.2 xBOOST Technology for Enhanced Bass

Factory head units often implement a bass roll-off at higher volumes to protect their stock woofers. The XLCA2 features xBOOST technology, which intelligently detects and restores these lost bass frequencies. This ensures a deep, powerful, and undistorted bass response from your aftermarket subwoofers and speakers, even at high volume levels. The restored signal provides a full-range audio experience that factory systems often lack.

2.3 Selectable Auto-On for Efficiency

The Selectable Auto-On feature allows the XLCA2 to automatically power on when it detects an audio signal from the factory stereo. This eliminates the need for a separate remote turn-on wire from the head unit, simplifying installation and ensuring the unit only draws power when the vehicle's audio system is active. This feature also helps prevent turn-on and turn-off pops that can occur with basic line output converters.

2.4 Remote Bass Control Included

For convenient bass adjustment, the XLCA2 includes a remote bass knob. This allows you to easily control the subwoofer output level directly from the driver's seat, providing on-the-fly adjustments to suit your listening preferences and music genre.

2.5 Versatile Output Options

The XLCA2 offers a 9.5V pre-out, a 12V trigger out, and dual amplifier outputs. These versatile options provide flexibility for complex car audio setups, ensuring compatibility with various amplifiers and audio system configurations. The high pre-amp outputട്ട്പുട്ട് വോളിയംtage helps deliver a cleaner, less distorted signal to your amplifiers, allowing for lower gain settings and reduced noise.

3. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

Proper installation is crucial for optimal performance of your NVX XLCA2. It is recommended that installation be performed by a qualified car audio professional. Always disconnect the vehicle's battery before beginning any electrical work.

3.1 വയറിംഗ് കണക്ഷനുകൾ

• സ്പീക്കർ ലെവൽ ഇൻപുട്ടുകൾ: Connect the high-level speaker outputs from your factory head unit or amplifier to the speaker input terminals on the XLCA2. Ensure correct polarity (+/-) for each channel. The XLCA2 can accept up to 400 watts RMS per channel.
• RCA ഔട്ട്പുട്ടുകൾ: Connect the RCA outputs (Bass Output and Main Output) from the XLCA2 to the corresponding RCA inputs on your aftermarket ampജീവപര്യന്തം.
• Power (REM In +12V): Connect a +12V constant power source to the REM In terminal.
• ഗ്രൗണ്ട് (GND): Connect the GND terminal to a solid chassis ground point in the vehicle.
• Remote Turn-On (REM Out): The XLCA2 provides a 12V remote output to turn on your aftermarket amplifiers. Connect this to the remote turn-on input of your amplifiers. This feature is activated by the signal sensing technology.
• റിമോട്ട് ബാസ് നോബ്: Connect the remote bass knob to the dedicated Bass REM port on the XLCA2 using the provided cable.

3.2 പ്രാരംഭ സജ്ജീകരണം

After all connections are made, re-connect the vehicle's battery. Turn on your factory head unit. The XLCA2 should power on automatically via its signal sensing feature. Verify that your aftermarket amplifiers also turn on.

4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The NVX XLCA2 features several adjustable controls to optimize your audio system's performance.

4.1 Main Level Adjustment

The Main Level knob controls the overall output voltage of the main RCA outputs. Adjust this to match the input sensitivity of your main full-range amplifier(s). Start with the knob at minimum and slowly increase until a clean, undistorted signal is achieved at your ampലൈഫയറിന്റെ ഇൻപുട്ട്.

4.2 Bass Level Adjustment

The Bass Level knob controls the output voltage of the bass RCA outputs. Adjust this to match the input sensitivity of your subwoofer amplifier. This setting works in conjunction with the remote bass knob.

4.3 Bass-X Threshold Adjustment

The Bass-X Threshold knob adjusts the sensitivity of the xBOOST bass restoration circuit. This allows you to fine-tune how aggressively the XLCA2 restores lost bass frequencies. Experiment with this setting to achieve the desired bass impact without over-boosting or distortion.

4.4 Remote Bass Knob Operation

The remote bass knob provides convenient, real-time control over the bass output level. Turn the knob clockwise to increase bass and counter-clockwise to decrease it. This allows for quick adjustments based on music content or personal preference while driving.

5. പരിപാലനം

The NVX XLCA2 is designed for reliable operation with minimal maintenance. To ensure longevity and optimal performance:
