AudioControl LCQ-1

Overview: The AudioControl LCQ-1 is a powerful six-channel signal processor that provides a gateway between factory installed source units and aftermarket amplifiers. It is a compact, six-channel, high-performance, OEM line-output converter with independent multichannel equalizers to custom tune your car audio system. The LCQ-1 allows you to easily "tune" your audio system & receive improved 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. No longer will you have to compromise when performing basic amplifier additions to a factory installed audio system. The active circuitry used in the LCQ-1 provides dramatically better sound quality & enhances the bass response. AccuBASS: 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. Factory installed amplifiers and woofers are (unfortunately) not designed to reproduce bass at high volumes. Car manufacturers adapt to this by taking the bass out of the signal when you turn up the volume. AudioControl developed the patent pending AccuBASS circuit to restore bass. After a quick and easy one-time setting, the AccuBASS circuit takes over the bass just as the factory system rolls off. You get smooth, seamless, and rock solid bass response regardless of volume level. Individual Equalization Controls: To custom tune your system, the LCQ-1 gives you dedicated equalization controls for the Front, Rear, & Subwoofer outputs. Channel Type Equalization Frequencies Level Adjustment Front 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 8kHz -12 to +12 dB Rear 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 8kHz -12 to +12 dB Subwoofer 31.5Hz, 50Hz, 63Hz, 80Hz, 1000Hz -12 to +12 dB 6ch Speaker Level Inputs: The LCQ-1 has active, high-voltage, high-impedance (20K Ohms) speaker-level inputs that accepts signals from high power, factory installed amplifiers (up to 400 watts per channel). This means the AudioControl LCQ-1 will work with factory-installed audio systems and give you a higher-quality signal with lower noise, lower distortion, and higher output voltage. These inputs get their signals from the speaker-level outputs of your factory installed source unit or amplifier. If your source unit has front, rear, & subwoofer speaker-level outputs, connect them to the three sets of inputs on your LCQ-1. AutoMode Input: If the source unit only has front & rear outputs, the Auto Mode circuitry in your LCQ-1 automatically routes the Channel 2 input channels to the (Channel 3) subwoofer channels. Internal Channel Summing: The LCQ-1 employs internal channel summing for interfacing with factory installed amplifiers with built-in crossovers. Channel summing lets you eliminate any factory-installed active crossovers. Many of today's factory stereo systems include separately amplified & crossed-over tweeters, midranges, & subs. If you are going to add aftermarket amps and speakers to the car you will need to combine (or sum) these separate signals into a single full-range signal for the new system. The LCQ-1 has the capability to combine together multiple (2, 4, or 6) input signals from the factory source unit into 2 channels. The LCQ-1 has internal jumpers that allow you to select which input signals will be summed into the Main outputs. When the jumper is moved to the "Sum" position, there will also be a corresponding green indicator light on the front of the LCQ-1. Note: The LCQ-1 is shipped from the factory in the non-summed (separate) position. Preamp Outputs: The AudioControl LCQ-1 is equipped with 3 stereo preamp outputs (Front/Main, Rear/Ch2, and Sub/Ch3) to connect to your aftermarket amplifier(s). Each stereo preamp output has an independent level control which allows you adjust the signal level from your factory source unit to match the input of your aftermarket amplifier(s). GTO (Great Turn-On) Circuit: The main speaker level inputs have a signal sensing circuit (GTO) that turns the unit "On" when there's a speaker level input signal, and turns the unit off when the signal disappears. Remote Output: The +12 volt DC remote output will trigger an amp to turn on whenever the LCQ-1 is "On". The remote's maximum current output is 1 amp. Optional Remote Control: You can add a multi-function dash control (161ACR2, sold separately) that allows you to set the level of the subwoofer. It also has an in/out switch for the equalizer function so you can hear the system before and after your tuning changes. The ACR-2 is a multi-function remote that gives you control over the level of the Channel 3/Subwoofer output so you can balance the bass level with the rest of the system. An additional feature of the ACR-2 dash remote is that it allows the equalization to be switched in and out of the audio circuit by tapping the switch. You can hear the system before and after the EQ adjustments. Installation: The LCQ-1 needs to be installed in the signal path between your OEM source unit (or factory amplifier) and aftermarket amplifier(s) and/or processor(s). Do not connect the LCQ-1 between the factory head unit and the factory amplifier. Locate the amplified speaker wires that are coming from your factory source unit and/or amplifier and connect them to the speaker-level inputs on the LCQ-1. In many cases you can find factory speaker leads in the rear of the vehicle or at the factory amplifier. Then use RCA connecting cables to connect the RCA outputs of the LCQ-1 to your aftermarket amplifier(s). Finally, connect +12V power and ground. The LCQ-1 has a 12-volt trigger input, but normally you will just let the GTO turn on circuit take care of that by itself.
