When we do upgrades, we audio geeks still tend to configure our sound to the best hertz and decibel we can get. Sometimes, even though we've upgraded to the best speakers or subwoofers, there is still room for small adjustments to achieve that perfect sound. This is where equalizers come in.
Equalizers are devices that lets you tweak your sound frequencies in different spectrum. When done right, it can improve your car sound and eliminate unwanted frequencies and customize your music. Equalizers come in different forms. It can be built in your head unit or receiver; or it can come as a separate in dash unit which can be classified as graphic, parametric or digital.
Graphic equalizers are the most common and can be used easily. It is makes use of sliders that represents the shape of the frequency you are trying to achieve hence the name. The sliders are used to cut or boost certain parts of the sound frequency whichever you desire.
Parametric equalizers is a little more complex than the graphic. It will allow you to adjust the width and center point of any frequency band. A parametric equalizer will also allow for Q adjustment (the quality of the curve of the band passed by the filter) of a frequency.
Digital equalizers offer the best of both worlds. From the graphical equalizer, it takes the ability of a user to see the adjustments made on the frequency. From parametric equalizers, it takes the ability to control the actual parameters of sound. The values are displayed on a screen digitally.
