AudioControl LC2i

2-channel line output converter for adding amps to your factory system

Looking for great sound from your factory radio? Would you like to upgrade your car’s premium system? AudioControl’s LC2i line output converter takes amplified speaker-level signals and converts them into high-quality preamp signals that can be fed to another processor or amplifier. In other words, it lets you create an awesome car audio system without disturbing your factory controls or features.


Overview: The AudioControl LC2i is an active, high-voltage OEM line converter. This compact, two-channel processor with active input circuitry, accepts speaker-level signals of up to 400-watts per channel from factory-installed source units or amplifiers. It then converts the speaker-level signals to high-quality pre-amp signals that can then be directed to after market processors and/or amplifiers. You no longer have to compromise when performing basic amplifier additions to factory installed audio systems. You can enjoy maximum sound quality while maintaining the use of your factory volume and steering wheel controls.

Compact Chassis Design: The AudioControl LC2i active, high-voltage OEM line converter features a compact chassis for an unobtrusive installation.

Two Channel Speaker-Level Input: The AudioControl LC2i features two channels of active speaker-level inputs that accept up to 400-watt signals. The two-channel line-output converter features four removable flat-head set-screw terminals for quick connection.

9.5V Preamp Outputs: The AudioControl LC2i is equipped with 9.5-volt preamp outputs w/ level matching controls. It features a pair of Main preamp outputs (for full-range amplifiers) and a pair of Bass preamp outputs (for subwoofer amplifiers).

Active Circuitry: The active circuitry used in the LC2i provides dramatically better sound quality and does not compromise the bass response.

AccuBass: The AudioControl LC2i features AccuBass processing for correction of bass roll-off. AccuBass processing automatically corrects for the bass roll-off that is common with many factory installed audio systems. AccuBass Bass Compensation works at any volume level.

Threshold & Level Controls: Simple “Threshold” and “Level” controls allow users to optimize the bass response to match their speaker system.

GTO (Great Turn On): The AudioControl LC2i utilizes selectable GTO auto sensing turn-on circuitry so no remote wire is needed. The LC2i turns on using the unit’s speaker-level inputs. It also provides a 12-volt trigger output to turn on your amplifier.

Remote Level Control: The AudioControl LC2i is equipped with a Bass Control Input (RJ-11) for optional remote bass level control (sold separately).

Mounting: The LC2i features integrated mounting flanges to mount the unit under a seat, in the trunk, or under the dash. No mounting hardware is supplied.

Power Connections: The AudioControl LC2i requires a hardwired power and ground connection to your vehicle’s 12-volt electrical system. The line-output converter features removable flat-head set-screw terminals for simple connection.
