Features

  • Upgrade your audio system while keeping your factory stereo: Convert speaker-level signals up to 400W 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.
  • Gain full control over your sound: Dual variable stereo gain controls and an LED clipping indicator allow you customize your audio and make adjustments easily.
  • 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.
  • Choose your turn-on mode: Features selectable Great Turn On (GTO) signal 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.
  • Turn on your other devices: By using the Remote Out, this line out converter can trigger up to 2 devices down the signal chain including amplifiers, line drivers, crossovers, or any other device with a Remote In.
  • Seamlessly integrate with late model vehicles: Onboard load selection switches allow factory amplifiers in modern systems to detect speaker loads and continue passing audio. Choose between 20 ohms, 60 ohms, and 20k ohms.
  • Save vehicle space: Designed with a compact slim chassis (6.9L x 3D x 1H including speaker connectors).

Description

The LC2i PRO join ranks with AudioControl’s most popular active line output converter, the LC2i. Adding a sub? Planning a full system? Either way, get the best possible signal from your factory sound system to your amplifiers. Load selection switches mean OEM integration has never been easier and the LC2i PRO will work with the most finicky factory sound systems. Installer friendly turn on trigger modes allow for flexibility via GTO Signal Sense (DC offset), audio sense, or remote 12 volt inputs. Compensate for factory bass roll-off with AudioContol’s patented AccuBASS and control your sub with the included ACR-1 level control.

    • Makes it so easy to add an amp and sub to a factory amplified system.
Simple install, easy to use, just what i needed. I added this to my vehicle that had a factory amplified sub already. I made a harness that plugged into to factory wires and ran it to the LC2. Super easy. I setup the LC2 to auto turn on. Super easy. I used the remote out to turn on the amp. Super easy. I didn't have to find and run a remote wire for anything. Super easy. It does what I needed it to do. It plays lower than what I expected. Im not positive, but it seems the bass roll off is under 30hz. It doesn't get much easier. ... show more

    • Great Product!
Awesome Product! No issues and setup was a breeze! I’m using a stock MyLink Chevy Headunit and works like a breeze once you figure out the wiring diagram! Well worth the money with the added option for load setting and ground options if having issues with alternator noise

    • Plenty of Bass on tap now. Say goodbye to bass roll off
If you have a Ford you're going to need this. Trust me it will wake up your subwoofer or any speaker thats behind it. Super easy to install and take your time with the adjustments to get it right. Watch youtube videos and you'll get it.

    • It made a noticeable difference
I used this on a BMW M5 with the stock sound system and was very impressed. Installation was straightforward and easy to complete. It made a noticeable difference in correcting the frequency curve and really improved the overall sound quality. Highly recommend for anyone looking to upgrade their factory system without a complicated install. ... show more

50,000 mile review. It's perfect. Does exactly what it's supposed to do. Works well with 16v input even though it's not advertised to. Compatible with any vehicle including my 2023 Tesla model 3 performance. Very durable. Sound quality is not an issue. Expensive for the money but you know you are getting a great product. ... show more
