For over two decades, AudioControl has been designing and manufacturing award-winning autosound 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 kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".

LCQ-1 - 6 Channel Line Out converter with EQ and AccuBASS™

Audio enthusiasts can now rejoice with the introduction of AudioControl's LCQ-1, a powerful six-channel signal processor that provides a gateway between factory installed source units and after-market amplifiers. The LCQ-1 allows Mobile Electronics enthusiasts to easily "tune" their audio systems and receive truly amazing sound quality. An ideal combination of discrete equalization controls combined with AudioControl's unique OEM integration circuitry, the LCQ-1 maximizes the performance of factory installed audio systems. Enthusiasts, who want amazing audio performance that only comes from custom-tuned audio systems, will truly enjoy the LCQ-1.

Basic, inexpensive, passive line output converters generally deliver poor sound quality and diminishing bass response. The active circuitry used in the LCQ-1 provides dramatically better sound quality and enhances the bass response. No longer will audio enthusiasts have to compromise when performing basic amplifier additions to factory installed audio systems. Enthusiasts looking for great sound will really love this product.

Designed for maximum sound quality and enhanced audio performance, the LCQ-1 is the latest AudioControl processor to incorporate AccuBASS™. This patent pending process automatically corrects for the bass roll-off that is common with many factory-installed audio systems. AudioControl engineers designed the LCQ-1 to be a very high-value processor, so subsequently it is equipped with a number of installer friendly features that simplify the OEM connection and calibration process.

Key Features:

Speaker-Level Inputs:

If you are like many people who like the look and features of their factory-installed source unit, but feel your system overall is lacking power and bass, we have good news. The LCQ-1 has high-impedance speakerlevel inputs that allow it to accept amplified signals (up to 400 watts per channel) from most 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 amplifiers, processors and speakers while keeping the convenience features of your factory-installed source unit. Unlike inexpensive speaker-level and line-output converters available, the LCQ-1 offers high sound quality.

Auxiliary Source Input:

A set of auxiliary RCA inputs connects the audio signal of an iPod or other stereo source into the system through the LC8i. Tapping the included LC8i remote knob will change from Main input to the Aux inputs and tapping again will change the knob function from subwoofer level control to auxiliary volume control.

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 LC8i and your external amplifiers. Therefore, we have equipped your LC8i with our unique GTO™ (Great Turn On) signal-sensing inputs. Once the GTO input of your LC8i detects a speaker-level signal on the Main Inputs, it powers up. When the speaker-level signal goes away, your LC8i will automatically turn-off. Optionally, your LC8i is also equipped with a standard 12-volt trigger (Remote In) that will allow you to turn on your LC8i in the traditional manner.

Internal Channel Summing:

The LC8i has the capability to combine together multiple (2, 4, 6, or 8) input signals from the factory source unit into 2 channels. This is page particularly handy when using the LC8i with a factory system that has multiple, actively crossed over signals being sent from an 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 LC8i 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.

Equalizer Specifications

Type of Equalizer
This determines the way the equalizer processes the signal from the source unit. A parametric equalizer allows to you adjust the center point of the frequency band you are adjusting as well the bandwidth which can be narrowed or widened. A graphic equalizer has fixed frequency bands and bandwidth and only the frequency bands can be adjusted. A digital equalizer uses a software program to tune your system.
A graphic equalizer typically has more adjustable bands and is less expensive, whereas a parametric will have fewer bands but offer a greater level of control and provide more tuning options. Digital equalizers will tune your system with the most detail and precision but require a computer and are typically a little higher in price.
Equalizer Bands
The number of graphic or parametric equalizer bands the receiver has. The better the EQ, the more likely you will be able to "tweak" your sounds to your desire.
6 band
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
31.5 - 8000 Hz
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
12 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
8.5 volts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 22000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Mixed feelings

March 11, 2014

I ordered this for my 2013 civic. I used it with 2 pdx amps. When I took everything to the install shop, they said it looked like I had recieved a used piece of equipment. The internal jumpers were all moved around and not in their default setting. After a few hours they fixed the problem. I'm not sure if it was a factory thing or sonic but needless to say I am not a happy customer. The unit works and does as advertised but tuning everything is a big headache. If I could go back I would get the LC7 and just adjust bass and treble from the head unit. Overall the unit does produce background noise, and seems to be lacking for my subs. Unit is acceptable, but if you truly want a nice piece of equipment spend $100 more on a Hertz BitOne.

Not Worth the Money

October 29, 2015

I have owned this since 2012. This unit appeared to be exactly what I needed to retain my stock head unit and add an aftermarket amplifier. However, the unit does not fully work as advertised. My head unit has no amplifier turn-on lead, meaning that when the ignition switch is on, the LCQ-1 and amp are always on. But wait, the LCQ-1 has the ability to turn itself on by sensing an incoming signal from its speaker inputs. Great idea. Too bad it doesn't work. I tried two of these units and neither would recognize the source signal and power up. The Audio Control technical support was great but none of their suggestions to get it working the way I wanted succeeded. I wound up installing a switch in my dash to turn the loc off when I am not listening to my stereo. This unit is noisy too. I thought my amp was generating transistor hiss during idle. Turns out it is the LCQ-1. With the car off, the head unit off, and just the loc and amp turned on, there is considerable idle hiss present. Disconnecting the low level cables from the LCQ-1 to the amp proved this. With just the amp feeding my speakers, the hiss disappeared. Lastly, removing the cover to change jumper settings is a pain. Well, not the removal but reattaching the cover after you change the jumpers. They really blew it with the design, as it takes quite a bit of effort to get the darn cover back on correctly.

LCQ-1 product Review

December 23, 2013

Excellent product, Simplistic in use. The quality is great with separate bands for front , rear and sub. The auto summing is a must have for higher end vehicle integration, unfortunately you lose the fader control for front and rear. What could be improved are the setting controls. as you have to remove the face panel to access, and I have found the GTO sensing hit or miss. But overall a great product with lost of flexibility and AC tech support are readily available to assist.

Only thing better than this is almost twice the price (JBL). You can't beat the reviews or the amount of control you get from this unit, especially when you'd rather keep your stock radio.
