Easily add an aftermarket amplifier or subwoofer to your vehicle’s factory audio system with this 6-channel active line output converter by AudioControl. The LC7iPRO converts speaker-level (high-level) audio signals to RCA preamp (low-level) signals so you can install an aftermarket amplifier or subwoofer without replacing your factory radio. This six-channel line output converter also features subwoofer control and AccuBASS technology so you can turn up the volume without losing bass.

• Compatible with most vehicles’ OEM audio systems: For use when adding aftermarket amplifiers to car audio systems without RCA preamp outputs.
• 6-channel interface with dual amplifier preamp outputs: Features three sets of active speaker-level inputs, three sets of full range main line-level outputs, and one set of low-passed bass line-level outputs for adding an aftermarket subwoofer.
• 400W (40V) peak power input per channel @ 20k ohms: For high-quality sound.
• 9.5V RMS (13V peak) maximum output voltage @ 14.4V: For efficient operation.
• AccuBASS processing: Recovers bass frequencies lost at higher volumes.
• Signal bus switch: Sum multiple input signals into a single channel output when connecting to premium factory systems with crossed-over speaker outputs for various speakers.
• Turn-on trigger mode switch: Choose between GTO Signal Sense (DC offset) and audio sense to automatically power the line output converter or use remote 12V input for manual control.
• Dual variable stereo gain controls with clipping indicator: Allows you to adjust main and bass output signals from -12dB to +12dB and indicates when levels are optimal.
• Selectable on-board load resistors: Including 20 ohms, 60 ohms, and 20k ohms impedance for newer factory-amplified vehicles.
• Selectable ground isolation: Choose from common, ISO (default), or 200 ohms.
• Dash remote level control: Adjust the bass output level for your subwoofer with the included ACR-1 attenuator knob.
• Slim chassis with integrated mounting brackets: Enables quick and easy installation.
• 5-year warranty: To protect against defects in materials and workmanship.
