JCPower LC55i Line-Out Converter for Subwoofer & Bass Restoration Processor Car Audio

The JCPower LC55i Line Out Converter is a specialized, single-channel line out converter engineered specifically for subwoofer amplifiers. This unit provides a powerful solution for integrating aftermarket subwoofers with factory audio systems, offering enhanced bass performance and flexible control.

Subwoofer-Specific Design

Unlike multi-channel line out converters, the LC55i is dedicated to subwoofer signals. This focused design ensures optimal performance for subwoofer applications, delivering a clean and powerful signal to your subwoofer amplifier.

Seamless Factory Integration and Versatile Trigger Modes

The LC55i converts speaker-level (or High-level) signals from your factory head unit into preamp-level (or low-level) RCA outputs, making it easy to connect aftermarket amplifiers. This eliminates the need for complex wiring or modifications to your factory system, preserving its original functionality while significantly upgrading your audio quality.

It also offers multiple trigger modes for seamless integration with your vehicle’s electrical system. These include:

• Remote In: Allows for traditional remote turn-on using a 12V signal from your head unit or another source, providing standard remote activation.
• DC On: Utilizes DC offset detection. The LC44i automatically powers up, along with any connected amplifiers, when it detects a DC voltage on the speaker-level input. This eliminates the need for a separate remote wire, simplifying installation, especially in vehicles with factory amplifiers that output DC offset.
• Audio Sensing: The converter also automatically turns on when it detects the presence of an audio signal (AC voltage) from the factory head unit, providing an alternative trigger mode for systems without DC offset.

These versatile trigger modes ensure compatibility with a wide range of vehicle setups, simplifying installation and ensuring reliable operation.

Built-In Bass Restoration (Harmonic Reconstruction)

The LC55i incorporates a built-in bass restoration processor that functions similarly to the LC11i and LC24i. It analyzes incoming audio signals and detects harmonic patterns of missing bass notes. Then, it reconstructs and synthesizes low bass frequencies based on those harmonics. This “bass recovery” process adds depth and fullness to the subwoofer’s output, especially beneficial when dealing with compressed audio, factory systems, or older recordings and music genres that filter out low frequencies or where these low frequencies don’t exist. This feature enhances the “feel-it” bass, making the subwoofer’s performance across a variety of genres including:

• Older Hip-Hop, Rap, Trap, and R&B: Restores the deep 808s and sub-bass that define these genres.
• Reggaeton, Latin Urban, and Dembow: Rebuilds the heavy low-end energy that drives modern Latin beats.
• Old-School Classics & Freestyle: Adds missing bass to vintage mixes, giving them a renewed sense of depth and power.
• Reggae and Dub: Delivers the warm, deep bass groove expected from roots and dub music.
• Mexican Regional Music: From Banda and Norteño to Cumbia and Corrido, the LC55i adds depth and richness to the traditional rhythms and bass lines.
• Classic Rock and Metal: helps restore low-end body to tracks that lack sub-bass but still need a full system response.

By restoring lost low-frequency information, the LC55i ensures that your subwoofer delivers a powerful and impactful bass response across a wide range of musical styles.

Adjustable Output Voltage

The LC55i offers adjustable output voltage settings (10V, 7.5V, 5V), allowing you to match the output signal to your subwoofer amplifier’s input sensitivity. This ensures optimal signal transfer and minimizes distortion.

Unique “Sweep” and “Wide” Bass Controls

Instead of traditional bass level and frequency controls, the LC55i features “Sweep” and “Wide” controls. These unique controls allow you to precisely shape the bass enhancement, providing greater flexibility in tailoring your subwoofer’s output. The “Sweep” control adjusts the center frequency of the bass boost, and the “Wide” control adjusts the bandwidth of the boost.

Switchable Subsonic Filter

The LC55i includes a switchable subsonic filter, which helps to eliminate ultra-low frequencies that can cause unwanted cone movement and distortion. This feature protects your subwoofer and improves overall sound quality.

Easy Subwoofer Integration

The LC55i simplifies the process of adding a subwoofer to your factory audio system. Its single-channel design, built-in bass restoration, and adjustable output voltage make it an ideal solution for subwoofer integration.

Key Features:

• Single-Channel Design: Optimized for subwoofer amplifiers.
• Built-in Bass Restoration: Corrects bass roll-off for enhanced low-frequency response.
• Adjustable Output Voltage: Ensures compatibility with a wide range of amplifiers.
• “Sweep” and “Wide” Bass Controls: Provides precise bass shaping.
• Switchable Subsonic Filter: Eliminates unwanted ultra-low frequencies.
• Simplified Installation: Streamlines subwoofer integration with factory systems.
