Why add an equalizer?

Equalizers will separate each tone control known as bands, equalizers may have five bands, nine bands, twelve bands and more!

Each band may control many different types of voice's and musical instruments.

The low base for instance will control large drums. The mid bass will control the smaller drums. The midrange will control human voice, and so on…..

The more the band’s the more control you have over your music sound reproduction.

Typically five to nine bands will work just fine in most automotive applications, adding more bands will simply increase the control you have over your music.

Typically there are two different types of equalizers on the market today:

• Graphic

• Parametric

Graphic

Graphic equalizers are the most popular, and are typically mounted under the radio, glove compartment, or any other location that is easily accessible.

Graphic equalizers have earned their name by the way the controls are aligned. That is, that once you have chosen your desired sound tone, it will look somewhat like a graph.

Parametric

Parametric equalizers accomplish the same goals however, they are typically mounted in the trunk and all tone controls are preset and left as they are, unless otherwise changed.

Parametric equalizes do not indicate the graph and are set to a specific frequency.

Passive or Active?

Passive

Passive equalizers are the most popular and simply indicate they are Pre-amp only and are designed to go from the radio pre-amp into the equalizer and then into your vehicle’s amplifiers.

Active

Active equalizers are equalizers with built in amplifiers, while this is a more convenient type of equalizer to install, it does have its disadvantages.

• Limitations of its power output.

• Expansion capabilities.
