For over two decades, AudioControl has been designing and manufacturing award-winning auto sound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems? Nothing sounds better than an awesome recording played back on a kick-butt system. Unfortunately, the acoustics of your vehicle can take away from your system's performance. While AudioControl products do not change the laws of physics (although they act as they do), auto sound enthusiasts have long known that AudioControl products "make good stereos sound better"

LC6i - 6 Channel Line Out Converter

AudioControl continues to simplify OEM integration with the new LC6i Six Channel Line Output Converter with internal summing. The LC6i is built on the same technology as its predecessor, the LC6. The LC6i converts speaker-level inputs from a factory radio or factory amplifier into high-quality pre-amp signals. The addition of internal summing capabilities and improved GTO™ signal-sense turn-on make the LC6i the perfect way to solve your OEM headaches.

The LC6i allows for the addition of aftermarket processors and amplifiers while maintaining the use of the factory volume and steering wheel controls. Internal signal summing and AudioControl's new GTO™ signal-sense turn-on make the LC6i a perfect OEM interface for a performance audio system.

The LC6i follows in the steps of the rampantly successful LC8 Eight Channel Line Output Converter, offering all of the same features for 6 channel systems at a reduced price. The LC6i accepts speaker-level signals, both crossed-over, and full range, and converts them to high-quality pre-amp signals. Signals from factory radios with built-in crossovers can be overcome by summing them together, internally, to provide a full-range preamp signal.

The LC6i provides the type of clean pre-amp signals installers are familiar with. Those who desire custom control over the sound can easily add one of AudioControl's many crossovers or equalizers which offer unlimited system design flexibility, clearly different than traditional OEM interfaces.

Speaker-Level Inputs

If you are like many people who enjoy the look and features of your factory-installed source unit but feel your system overall is lacking power and bass, we have good news. The LC6i has high-impedance speaker level inputs that allow it to accept amplified signals from all known factory-installed source units (even Bose) and output a high-quality pre-amp signal via standard RCA connectors. This will allow you to add better-quality aftermarket amplifiers, processors, and speakers while keeping the convenience features of your factory-installed source unit. Unlike inexpensive speaker-level and line-output converters, the LC6i offers the highest sound quality and can handle the full signal strength of a 400-watt amplifier.

GTO™ Signal-Sensing Inputs

Most factory-installed source units lack the features that make it easy to upgrade with really good-sounding, performance aftermarket products. One of those key features is a 12-volt trigger that will turn on devices like the LC6i and your external amplifiers. Therefore, we have equipped your LC6i with our unique GTO™ (Great Turn-On) signal-sensing inputs. Once the GTO input of your LC6i detects a speaker-level signal on the Main Inputs, it powers up. When the speaker-level signal goes away, your LC6i will automatically turn off. Optionally, your LC6i is also equipped with a standard 12-volt trigger (Remote In) that will allow you to turn on your LC6i in the traditional manner.

12-Volt Output Trigger

Since you will be using an external amplifier(s) and processor in your system, you will need the ability to "trigger" or turn on these devices (a romantic dinner won't quite work here). Your LC6i has a high-current 12-volt output (labeled Remote Out) that will provide a trigger to these remote devices when the LC6i is powered up. Please note that this output is not to be used as the main power for these devices.

Internal Channel Summing

The LC6i has the unique ability to internally sum together multiple (4 or 6) input channels from the factory source unit into 2 channels. This is particularly handy when using the LC6i with a factory system that has multiple, actively crossed-over signals being sent from the OEM source unit or amplifier(s). For example, in some vehicles, there is an actively crossed-over tweeter, midrange, and woofer all in the front of the vehicle. The LC6i lets you take all of those signals and sum them together to get a high-quality, full-range, pre-amp signal without the use of any additional cables or hardware.

AutoMode Inputs

Sometimes in life (and car audio) we need more outputs than inputs. Therefore we have equipped your LC6i with AutoMode inputs that take the Channel 2 signal and automatically feeds it to the Channel 3 outputs, provided there is no signal present on the Channel 3 inputs. This means your LC6i will accept two input channels and give you four output channels. Or it can accept four input channels and give you six output channels.

Great value

Gives your system a great sound better than the standard converter

AudioControl LC6i (Black)

This unit is amazing! I bought a new vehicle and wanted to add my 5 channel amp to the factory head unit since it already had bluetooth, satellite radio, and was integrated into my climate controls.. The amp had high-level inputs, but I quickly found out that the signals are attenuated from the radio out to the speakers so the amp sounded terrible. So I did some research, bought this unit, and used the 3 pairs of outputs and signal summing to restore the full signal to my amp. Once I added new speakers and hooked up my subs, the sound is everything I could want and more. Plus the GTO circuit works perfectly, I used the remote out from the unit as a turn-on signal for my amp. This is an indispensable product, I could not have done a clean-sounding install without it! If you want to keep your factory head unit, this is the way to go.

Look of stock, with big aftermarket sound!

I have a 2016 GMC Sierra with an 8-inch touch screen. I wanted to add new speakers and amps, but didn’t want to lose the factory look as the display is pretty nice. I thought about aftermarket, but after finding out that I needed to cut apart the inside of the dash, I said forget it and gave the Audio Control LC6i a shot. I’m glad I did! I couldn’t be happier. Nice clean sound! The auto remote turn on is a great feature! I have no issues with it as of yet, and yes it shuts off when there is no signal present. Thank you for the audio control. I will recommend it!

Great Value

If you are interested in upgrading your vehicle sound system while keeping your factory stereo but adding multiple apps and speakers this is the product for you. Installed right this will ensure you add 4 channel full range speakers plus a separate channel for bass and then some. Well worth the money for a quality product from audio control.

It works just like I expected. I would definitely purchase it again if I had to.
