Audiotek CX4 2-Way Car Audio Passive Crossover Networks User Manual

1. Introduction

The Audiotek CX4 is a high-performance 2-way passive crossover network designed for car audio systems. Its primary function is to separate the audio signal into distinct frequency ranges, directing high frequencies to tweeters and low frequencies to woofers. This ensures that each speaker driver receives only the frequencies it is designed to reproduce, resulting in clearer sound reproduction and improved overall audio quality in your vehicle. This manual provides essential information for the proper installation, operation, and maintenance of your Audiotek CX4 crossover networks.

5. Setup and Installation

The Audiotek CX4 crossover networks are designed for straightforward integration into your car audio system. Follow these general steps for installation.

5.1. Mounting Location

Choose a dry, secure location within your vehicle that is protected from direct sunlight, extreme temperatures, and moisture. The compact size of the CX4 allows for flexible placement. Ensure there is adequate ventilation around the unit.

5.2. Wiring Connections

The CX4 features clearly labeled terminals for input, woofer output, and tweeter output. Refer to the diagram below for proper wiring.

• Input (Eingang): Connect the audio signal from your amplifier's full-range output to the "INPUT" terminals on the crossover. Ensure correct polarity (+ to + and - to -).
• Woofer Output (Tiefton): Connect your woofer speaker to the "WOOFER" terminals. Maintain correct polarity.
• Tweeter Output (Hochton): Connect your tweeter speaker to the "TWEETER" terminals. Maintain correct polarity.

5.3. Tweeter Level Adjustment

The CX4 allows you to adjust the tweeter output level to match your system and listening preferences. There are three selectable settings:

• 0dB: Standard tweeter output.
• -3dB: Slightly reduced tweeter output.
• -6dB: Further reduced tweeter output.

Select the desired setting by moving the jumper or switch located near the tweeter terminals. Experiment with these settings to achieve the best balance between your woofers and tweeters.

After all connections are made, double-check all wiring for correct polarity and secure connections before reconnecting the vehicle's battery.

6. Operation

The Audiotek CX4 is a passive crossover, meaning it does not require external power to operate. Once correctly installed and wired, it will automatically filter the audio signal from your amplifier, sending the appropriate frequencies to your connected woofers and tweeters.

The crossover point of 3.5 kHz ensures that frequencies below this point are directed to the woofer, and frequencies above are directed to the tweeter. This optimized distribution of sound frequencies enhances the clarity and definition of your car audio system.

7. Maintenance

The Audiotek CX4 crossover networks require minimal maintenance.

• Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Periodically check all wiring connections to ensure they remain secure and free from corrosion.
• Avoid exposing the unit to liquids or extreme temperatures.

8. Troubleshooting

If you experience issues with your Audiotek CX4 crossover networks, refer to the following common troubleshooting steps:

If troubleshooting steps do not resolve the issue, please contact Audiotek customer support or a qualified car audio technician.
