AudioControl LC1i 2-Channel Line Output Converter & Line Driver

The AudioControl LC1i is a two-channel active line output converter and line driver built to extract a clean preamp signal from factory radios for aftermarket amplifiers. Its OEM-friendly load switching and flexible turn-on options make it a practical choice for diverse installation scenarios.

• Two channels of speaker level inputs: Accepts high-level factory outputs with up to 40 Vrms input handling, enabling robust feeding of downstream amps. Maximum input: 40 Vrms / 400 W (20kΩ setting).
• Two channels of line level inputs: Provides available line-level feeds with an input impedance of 7kΩ for clean, low-noise signal transfer.
• Load Selection Switch: Works with selectable input impedance to match the input stage for reliable OEM integration across different vehicles.
• GTO Signal Sensing / Audio Sense / Remote Turn-On Modes: Offers flexible trigger options to turn the unit on from a factory source or an aftermarket head unit, improving installation versatility.
• Ground Isolation Switch: Helps minimize ground loop noise by isolating grounds between the LC1i and other components in the system.
• Preamp Outputs: One dual-channel preamp output with a maximum of 9.5 Vrms (13 V peak); gain adjustable ±12 dB; output impedance around 150 Ω.
• Frequency Response / Noise performance: 20 Hz – 50 kHz ±1 dB with THD of 0.01% and SNR > 110 dB for high-fidelity signal reproduction.
• Remote In / Remote Out: Remote In with GTO/Audio Sense control and 12 V DC Remote Out (active when the unit is on).
• Power and size: Compact 4.8" L × 3" D × 1" H chassis; 120 mA current draw; recommended 1 A fuse.
• In the box: LC1i, Speaker and Power connectors, Manual, Warranty downloads full line catalog literature.

The LC1i excels in factory-to-aftermarket builds, delivering a clean preamp signal to amplifiers while remaining in the system for future head-unit upgrades. Its impedance options, flexible trigger modes, and ground isolation address common OEM integration challenges, making it a versatile choice for multi-amp or subwoofer-inclusive setups.
