Six Channel Line Output Converter  

with Multi-Channel Equalization and AccuBASS™

   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!

• Independent Front, Rear, and Subwoofer equalizers let you custom tune

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.

Note: If your source unit has front, rear, and subwoofer speaker-level out-

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.

 C12 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.

 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

will extend the normal one-year warranty to a full 

five years
