Features

  • Upgrade your audio system while keeping your factory stereo: Convert speaker-level signals up to 400W (40V) per channel from your OEM radio or amplifier to high quality pre-amp output signals directed to aftermarket subwoofers, amplifiers, and processors.
  • Maximize your bass: AccuBASS processing technology corrects and restores bass roll-off when the volume is increased on the factory radio.
  • Seamlessly integrate with most vehicles: Onboard load selection switches (20 ohms, 60 ohms, and 20k ohms) allow interfacing with modern factory-amplified audio systems.
  • Connect to any factory audio system: Easily sum or separate audio signals by using the the Signal Bus switch.
  • Control subwoofer levels from the drivers seat: Includes the ACR-1 dash knob remote, a 20-foot remote cable, and metal housing with integrated removable mounting tabs for custom flush mount installations.
  • Gain full control over your sound: Fixed and variable outputs with discrete onboard level controls allow you customize your audio and make adjustments easily.
  • Choose your turn-on mode: Features selectable Great Turn On (GTO) signal sense and audio sense to automatically power the LOC or remote 12V input for manual control.
  • Eliminate noise: Selectable ground isolation switch allows you to remove ground buzz or alternator whine.

  • Save vehicle space: Designed with a compact slim chassis to fit discreetly in your car without taking up extra room. Dimensions: 6.9L x 3D x 1H (including speaker connectors).

Description

AudioControl brings you our most advanced line of LOCs yet. OEM integration has never been easier with the host of intelligent built-in features like LMC (Load Matching Circuit), allowing even the most finicky factory sound systems to no longer be an obstacle to great sound. Installer-friendly trigger modes offer flexibility and an expedited installation time since the units can be turned on via GTO Signal Sense (DC offset), audio signal sensing, or standard remote 12 volt input. All PRO series products feature AudioContol’s patented AccuBASS for restoring low frequency output diminished by factory processing, and an ACR-1 level control is included to dial in the perfect level for your subwoofer right from the comfort of the driver’s seat. The Pro series ensures that you will start with the clean, powerful signal you need to take your system from sounding good to sounding great.

  • Brilliant Line convertor.
I've used the AudioControl LC5i Pro with AccuBASS and have been very impressed with it. It delivers a clean signal, restores lost bass exceptionally well, and integrates perfectly with the factory head unit. The sound quality improvement was noticeable immediately, making it an excellent choice for anyone looking to upgrade their audio system without replacing the stock radio. ... show more

  • A MUST HAVE FOR THE NEWER FACTORY CARS/TRUCKS.
Great upgrade from my LC7i. It has basically fixed the headache i had with the low voltage i was getting because of the factory system that Chevy uses for the 19-23 Silverados. It also brought back allot of safety chimes I couldn't get because of the older LC7i I was using didn't have the load jumpers selector switches. ... show more

  • It’s audio control you already know
As a line input converter, it is probably the best. As for the bass restoration, that really depends on the music you’re listening to of course this is in the description. One thing to know is if you are trying to produce ultra low base tones, audio control cuts off all frequency below 20 Hz. So essentially the stuff you can’t hear, but what will make your car shake the hardest if you’re a serious bass head and are trying for a SPF build ... show more

  • Does exactly what you need it to do to a Factory Head unit. Get one.
Paid to have this installed with a 5 channel amp to the head unit of a Camry Hybrid and it works as intended. Good clean power from the head unit to my amp.
