The AudioControl LC2i is a two-channel line-out converter designed to integrate with factory-installed car audio systems, enabling the addition of aftermarket amplifiers and subwoofers. It accepts speaker-level inputs, converting them to preamp signals, and features AccuBass processing to address bass roll-off common in factory setups. The device requires hardwired power and ground connections and offers an optional remote bass control for in-cabin adjustments. Installation involves careful consideration of vehicle-specific wiring and placement, with user reports indicating successful integration across a range of models.
Key Features of the AudioControl LC2i
The AudioControl LC2i provides several features designed to enhance existing car audio systems without requiring a complete overhaul. These features cater to users seeking improved sound quality and expanded audio capabilities.
Dual-Channel Active/Speaker-Level Input The LC2i functions as a two-channel line-out converter, accepting both active and speaker-level input signals. This broad compatibility allows integration with a diverse range of factory head units and amplifiers. The device can handle up to 400 watts of power per channel, facilitating seamless connection with high-output systems. This feature is particularly useful for retaining the factory amplifier while adding an external amplifier dedicated to a subwoofer.
Preamp Output and Level Matching The LC2i provides 9.5V preamp outputs, suitable for driving external amplifiers. These outputs allow for level matching, enabling users to fine-tune the signal strength to optimize performance with their chosen amplification equipment.
AccuBass Processing A key feature of the LC2i is its AccuBass technology. This circuitry is designed to correct the bass roll-off often present in factory audio systems, ensuring that low-frequency bass response is maintained even at lower volume levels. This prevents a loss of punch and impact in the bass frequencies.
Balanced Differential Inputs The LC2i incorporates balanced differential inputs, which contribute to noise-free audio signal transfer, resulting in superior sound quality. This minimizes interference and ensures a cleaner audio signal.
High Input Level Capacity The device has a maximum input level of 40 volts RMS, ensuring compatibility with a wide range of audio systems. This high input capacity allows the LC2i to function effectively with various factory audio configurations.
Optional Remote Control An optional remote bass level control is available for separate purchase. This allows users to adjust the bass output while driving, providing greater control over the audio experience without needing to directly access the LC2i unit itself.
Installation Requirements and Practical Considerations
Installing the AudioControl LC2i requires attention to several technical and logistical details. Proper preparation and adherence to manufacturer guidelines are crucial for a successful installation.
Power and Ground Connections The LC2i requires hardwired power and ground connections for operation. This necessitates connecting the device directly to the vehicle’s battery or an existing power circuit capable of supplying sufficient current. Secure connections and appropriate fusing are essential to prevent electrical issues or damage to the vehicle’s wiring system.
Speaker-Level Input Configuration Connecting the speaker-level inputs requires careful attention to wiring configurations, which can vary significantly depending on the vehicle model and factory system. Users should consult the vehicle’s wiring diagram or seek assistance from a professional installer to ensure correct connections.
Mounting and Space Considerations The LC2i is designed with a compact form factor, but users should still carefully plan its placement within the vehicle. Mounting options include direct attachment to the subwoofer enclosure, placement in the trunk, or installation under the dashboard. The integrated mounting flanges facilitate secure and flexible installation. It is important to ensure the device is not obstructed and that all connections remain accessible for future adjustments or troubleshooting.
Remote Turn-On Circuitry The LC2i features an optional GTO (Ground Trigger Output) turn-on circuit, which can eliminate the need for a traditional remote wire to activate the external amplifier. However, users should verify whether this feature is compatible with their specific amplifier and setup. Some amplifiers may still require a separate remote trigger connected to the vehicle’s ignition system.
Configuration and Tuning After installation, users may need to adjust the LC2i’s settings to optimize audio performance. The device includes threshold and level controls for bass response, as well as preamp output level adjustments. These settings should be fine-tuned based on user preferences and the characteristics of the external amplifier and subwoofer.
User Experiences and Installation Tips
User experiences documented in online forums and installation threads provide valuable insights into the practical aspects of installing and configuring the AudioControl LC2i.
Compatibility with Factory Systems User reports generally highlight the LC2i’s compatibility with a wide range of factory audio systems. However, successful integration often depends on careful wiring and signal routing.
Wiring Variations Users have noted that wire colors and pin assignments can vary significantly depending on the vehicle and factory wiring harness. Consulting the vehicle’s wiring diagram or a professional installer is highly recommended to ensure correct connections.
Recalibration and Troubleshooting In some cases, users may need to recalibrate the remote control or consult the manufacturer for troubleshooting assistance.
Retrofitting Factory Systems The LC2i is frequently used in retrofitting factory systems with minimal disruption, allowing users to add aftermarket components without replacing the entire audio setup.
Conclusion
The AudioControl LC2i is a versatile line-out converter designed to enhance factory audio systems by enabling the addition of external amplifiers and subwoofers. Its key features, including AccuBass processing, 9.5V preamp outputs, and the availability of an optional remote control, make it a suitable choice for users seeking improved audio performance. Successful installation requires careful attention to power and ground connections, speaker-level input configuration, and vehicle-specific wiring. Consulting manufacturer guidelines and incorporating practical tips from experienced users can ensure a smooth and effective integration into a wide range of car audio setups.
