AudioControl LC5i-PRO 5-Channel Line Output Converter w/ AccuBass

The AudioControl LC5i-PRO is a 5-channel line output converter with AccuBASS® built in, engineered for OEM integration and bass restoration in modern factory systems. It combines flexible high‑level inputs with precise output control for a clean, tunable signal path that car audio enthusiasts demand.

• Four-channel speaker-level inputs: Four channels of active speaker-level inputs (up to 40 Vrms input handling) designed to accommodate high‑level factory outputs while maintaining signal integrity.
• Fixed and variable outputs with discrete-level controls: Allows exact level matching and tuning of each channel, giving you consistent, repeatable results across system builds.
• AccuBASS® processing: Restores bass that factory processing may roll off, helping deeper, more natural low end without overdriving the rest of the system.
• ACR-1 dash remote included: Enables subwoofer level adjustment from the driver's seat for on‑the‑fly tuning during installation and setup.
• Load Selection Switch: Lets you select load scenarios to optimize performance with your particular amplifier or processor chain.
• GTO™ Signal Sensing / Audio Sense / 12V remote input: Flexible turn-on options via DC offset, audio sensing, or standard remote input to suit different vehicle wiring setups.
• Ground Isolation Switch: Reduces potential ground-loop and noise issues, helping maintain signal purity in complex vehicle electrical environments.
• 5 preamp outputs: 4 main outputs plus 1 dedicated bass output, simplifying routing to multiple amplifiers or processors in a multi‑channel install.
• High‑fidelity performance: Maximum output level 9.5 Vrms (13 V peak), output gain ±15 dB, output impedance 150 Ω, THD 0.01%, SNR >124 dB, and frequency response 20 Hz–20 kHz for a wide, clean audible range.
• Remote Out: 12V DC remote out is active whenever the unit is on, enabling reliable turn-on control for downstream gear.
• Compact physicals: Dimensions 7" L × 5.1" D × 1.14" H; weight 1.1 lbs., allowing easy installation in tight dash or enclosure spaces.
• In the box: LC5i PRO, ACR-1, 20′ Phone Cable, Speaker and Power connectors, Manual, Warranty downloads.

The LC5i-PRO is ideal for systems where OEM head units need to be preserved or enhanced without sacrificing bass or clarity. Its LMC Load Matching Circuit and versatile trigger options support stable, high‑fidelity integration, while the AccuBASS® technology and the included ACR-1 remote give you practical, on‑the‑spot control during dialing and tuning.
