. . . Level Matching for Autosound . . .

?or Why is my system so noisy?

Introduction

With the advent of really high-performance automotive sound systems, the old problem of noise (in

its various forms) has once more raised its ugly head. Even if the manufacturer has done their

engineering homework, it’s still really easy to forget some detail during installation and make even

the quietest components seem noisy.

Consider:

• A head unit with an integral power amplifier.

• An outboard equalizer, with input and output level controls.

• An outboard power amplifier, with high- and low-level inputs.

What we have here is a potential disaster. If the level adjustments between the various components

aren’t made correctly, the finished system could be any of the following:

• Noisy

• Distorted

• Seemingly under powered

In this guide, we’ll discuss some of the causes of noise in audio systems and explore some ways of

dealing with them. Along the way, we’ll also cover the interface problem listed above. At times,

this guide may seem a bit long-winded. It is, but the risk of spreading misinformation by oversim-

plification is quite high so do yourself a favor and stick with us; the time you spend reading this

will be well spent.
