Product Highlights

Designed to cater to all music lovers in mind, the AudioControl LC7i provides a great in-car audio experience. It was first launched back in May 2016 and subsequently, is considered a great DSP to buy in 2020. It allows car owners to retain their factory installed source unit and subsequently increases the system’s performance by leaps and bounds.

The LC7i incorporates AccuBASS ®, a patented process that automatically targets and corrects any issues involved with bass quality. AudioControl’s unique circuitry restores the bass and allows for flexibility when powering signals downstream to single or multiple factory amps.

Additionally, the LC7i also fits compactly into the chassis, enabling easy upgrades to the factory-installed audio system.

Features

  • Optional ACR- 1 remote that allows the user complete control of the subwoofer level
  • Six channels of active speaker level inputs that accept up to 400 watts per channel
  • GTO™ (Great Turn-On) Circuit that powers up the LC7i when it detects a signal on the speaker level input
  • Output level control
  • Internal channel summing that allows interfacing with factory-installed amplifiers with built-in crossovers
  • Dimensions:
    7.5”W x 4.7”D x 1.2”H
    Weight : 1.5 lbs (0.7 kg)

What’s in the Box:

  • LC7i
  • Speaker and power connectors
  • Manual
  • Warranty: 5-year warranty

What We Like About AudioControl LC7i

AccuBASS™ is a patented feature that is incorporated in AudioControl LC7i that restores bass frequencies on a factory system that rolls off the bass as you increase volume.

There are two AccuBASS settings:

1. AccuBASS Threshold that determines when AccuBASS turns on
2. AccuBASS level that adjusts how much bass can be restored.

There also exists a status LED light that lights up when AccuBASS is active.

To initially set up the AccuBASS, set the Threshold all the way to the left and then the Level knob at the 12 o’clock position. Then, start playing music that has a lot of bass, slowly turning up the head unit volume until you hear the bass dropping.

Now, slowly turn up the Threshold dial clockwise until the status LED illuminates and you can hear the bass being restored. Now that you’ve set the Threshold, you can adjust the AccuBASS Level knob to your preference.

It really is that simple and you can now listen to uninterrupted, high-quality music with spectacular bass, exactly how you like it.

PROS

  • Easy setup
  • Fits well into compact chassis
  • Comes with wireless features
  • Best restoration feature
