AudioControl LCQ-1 Owner's Manual

   The LCQ-1 is your gateway to amazing sound from a factory head unit.  It 

is a compact, six-channel, high-performance, OEM 

line output converter with independent multi-

channel equalizers to custom tune the system. 

AudioControl’s  patent pending AccuBASS™ 

compensation corrects for the factory bass 

roll-off present in many of today’s cars.  

In short; the LCQ-1 can make every car 

sound amazing.

   If you want even more, add the 

optional dash mounted level control 

(ACR-2) which allows control of the 
subwoofer output. The ACR-2 will 

also operate as an in/out switch for the 

EQ section. Very handy addition!

Here are some of the cool things that your LCQ-1 does:
• Independent Front, Rear, and Subwoofer equalizers let you custom tune  

 your 

system

• AccuBASS™  bass compensation, so you can correct for the factory bass  

 

roll off, Patent Pending

• GTO™ - signal-sensing inputs to turn the LCQ-1 on automatically 
• Channel summing lets you eliminate any factory-installed active 
 crossovers 
• Active speaker-level inputs accept high power factory amplifier outputs
• AutoMode Inputs turn 2 inputs into 3 outputs 
• Compact size for quick, easy installation
•  Input for optional ACR-2 remote mounted bass level control 
•  Bulletproof 5 year warranty (When installed by an authorized

Quick Install Guide

Since some of you will want to install your LCQ-1 on your own we offer a 

few reminders in the following short section to speed up your installation of 
the: You should also refer to diagrams on page 9 and 10 as guidelines.

– Physically mount the LCQ-1 in a location that keeps it away from soda 

spills, food crumbs, and curious fingers. Select a location that allows you ac-
cess to the top panel equalization controls.

— The LCQ-1 needs to be installed in the signal path between your OEM 

source unit (or factory amplifier) and after-market 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 your LCQ-1.  In many cases you can find factory speaker leads in the 
rear of the vehicle or at the factory amplifier that are easy to access.

puts, connect them to the three sets of inputs on your LCQ-1. If the source unit 
only has front and rear outputs, the Auto Mode circuitry in your LCQ-1 auto-
matically routes the Channel 2 input channels to the (Channel 3) subwoofer 
channels. 

˜ Use RCA connecting cables to connect the RCA outputs of the  

LCQ-1 to your after market amplifier(s). If this is not obvious to you, quickly 
pack up your LCQ-1 and run to your nearest authorized AudioControl dealer to 
have them perform the installation. You will thank us later. 

™ Connect +12 power, and ground.  Note: 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.

š Connect your amplifier trigger input to the 12-volt trigger output of the LCQ-1. 
› Turn your amp gains fully down before turning on the system. 
œ Turn on the system and level match your LCQ-1 to your source unit, signal 

processor and amplifiers. For more help see our technical videos at
