Introduction

Congratulations on your purchase of the EQS, the

worlds first six channel pre-amp equalizer from AudioControl, the leading manufacturer of performance signal processors and analyzers. Whether this is your first product from the rainforest dwellers of AudioControl or you are already a firm believer, you will definitely enjoy how great the EQS can make your performance autosound system sound.

Now before you start salivating too much just thinking

about the benefits of the EQS, take a few minutes to sit back,

have a latte’, decaffeinated if necessary, and read through this manual. It contains lots of useful facts and information - - and besides, we

spent a lot of time writing it!

KEY FEATURES OF THE EQS FEATURES AND HIGHLIGHTS

Dual-bandwidth Equalization: Car interiors vary

widely in size and acoustic make-up. In addition doors, kick-

Here are some of the cool features that are enclosed in

this magical box:

· Dual-bandwidth equalization

· 13 volt pre-amp line driver

· Auto Select

Inputs

· Voltage indicator LED’s

· Speaker level inputs

· PFM subsonic filter

· Balanced differential inputs

panels, and rear decks don’t make the best location for speaker placement causing your high performance speaker system to sound somewhat lackluster. The EQS offers maximum equalization controls for each area of the audio spectrum. One-third octave bass equalization combined with one-half and full octave high frequency equalization offers an ideal level of control.

13 Volt Pre-Amp Line Driver: The EQS offers a high

quality line driver that takes the low output voltage of a source unit and increases it up to 18dB (13 volts peak). This allows you to maximize the signal-to-noise of your system and drive your amplifiers to their maximum output without clipping. No hiss, clicks, or pops plus maximum sound quality.

Auto Select

Inputs: Whether your source unit has

two, four, or six outputs, the EQS will automatically switch the inputs to maximize your equalization controls.

EQS

Speaker Level Inputs: If you are like many people and

like the look and features of your factory installed source unit but feel it’s lacking power and bass, we have good news. The EQS has a unique high impedance speaker level input that will interface with most factory installed source units (even Bose) and let you add amplifiers and speakers to your hearts content. However, unlike some of the cheesy speaker level line output converters available, the EQS offers a very high fidelity sound quality input.

PFM Subsonic Filter: This unique feature is legendary

with many AudioControl fanatics for it’s ability to fine-tune the bass response of any system. Why waste power on nasty subsonic information when your Programmable Frequency Match (PFM) filter will help you clean things up.

Bulletproof Warranty: The most important feature

of all. Every AudioControl product is

selflessly designed and

manufactured by the occupants of our

rainforest factory. We take every effort to ensure that you will have many years of enjoyment out of your EQS. To ensure the performance of your new toy, we highly recommend that you allow your authorized AudioControl dealer to perform the installation. Not only do they have all the right knowledge and tools, but in the unlikely chance your EQS should stop working, we will back it with a limited five years parts and labor warranty. Should you choose to install it yourself we will still give you one-year parts and labor warranty. To activate your warranty, you need to FILL OUT

AND SEND IN YOUR WARRANTY CARD!

We also recommend that you save your invoice or sales slip as proof of installation and ownership. Not only is it necessary for warranty purposes, but should your EQS ”disappear” one day while your car is parked at your local latte’ stand, you will find insurance companies very unforgiving without proof of purchase.

QUICK INSTALLATION INFORMATION

For those of you short on time but high on ambition we offer the following section to speed up your installation of the EQS:

1. The EQS needs to be installed in the signal path between

your source unit and an external amplifier(s). If this is not obvious to you, quickly pack up your EQS and run to your nearest authorized AudioControl dealer to have them perform the installation. You will thank us later.

2. Physically mount the EQS in a location that keeps it away

from soda spills, food crumbs, and curious fingers. However you will want to select a location that allows you access to the equalization controls.

3. Hook up +12 volt power,

-12 volt ground, and remote turn-on. If you need to know more, then read on. Heck if you don’t think you need to

Figure 1: Basic EQS System

know more, you should still read on, because you can never know too much.

4. Level match the inputs of your EQS to your source and then adjust the outputs to match with your amplifier inputs.

Note: You will want to turn the gains on your amplifiers

DOWN to maximize your systems performance.

5. Now comes the fun apart. Set your equalization controls to where your system sounds the most balanced yet dynamic. More about this in the section titled “Adjusting Your Equalizer”…and you thought you would not have to read the rest on the manual. Hah!
