What are Bass Restoration Processors?

When it comes to your car audio system, bass is an extremely important factor. In order for you to truly enjoy the music in your vehicle, you will need to be able to hear your music’s low frequencies! Although adding a subwoofer to your car audio system will definitely allow you to hear more of those low frequencies, a bass restoration processor digitally restores that heart-pounding bass that is still missing from your music. Bass restoration processors are the perfect add-on for those who want the lowest hitting bass possible. You can read this Knowledge Base Article if you’d like to learn about all the different types of sound processors.

1How a Bass Restoration Processor Works

A bass restoration processor, also called a bass booster or bass restoration processor, such as AudioControl’s Epicenter, has multiple adjustments which allow the user to bring out the ideal amount of bass for their music. Most of the time, they have three types ofAudioControl Epicenter adjustments: frequency, width, and level. The frequency adjustment allows you to choose the specific frequencies you would like brought out in your music. This allows you to have complete control over the bass in your system. Width adjustments on bass restoration processors allow you to choose the amount of frequencies that are affected. You can adjust the processor to affect a wide or narrow bandwidth of frequencies around the selected frequency. For example, if you have set the processor to affect 30 Hz, a narrow setting would only mainly affect that frequency, while a wide setting would affect a large range of frequencies around 30 Hz. Lastly, you can adjust the amount of manipulation for that selected frequency at the selected width, with the level adjustment. If you would like to get the most bass possible, you can crank the level knob up. In addition, you can also turn it all the way down if you would like to. For convenient adjusting of this setting, this knob is usually located on an included bass remote.

2Types of Bass Restoration Processors

Most bass restoration processors are the same, with some varying features such as different types of bass adjustments. Most of them include a bass remote, however there are a couple that do not have this accessory included. In addition, these sound processors have a variety of maximum output voltages. Lastly, most bass restoration processors have an auxiliary input, although there are a couple models that don’t come with this input.

2How to Wire a Bass Restoration Processor

Most bass processors are connected the same way. There are Ground, 12V power, and remote inputs on the processor that will all be hooked up to your aftermarket car stereo. The ground wire from your car stereos is going to go straight to the processor, the yellow 12V wire will also go straight from the car stereo to the processor, as well as the blue and white remote wire which will go from your car stereo – right to the bass processor. This will allow you to tie in power for the processor right from your car stereo. To get signal to the processor, you’re going to hook up an RCA from your car stereo’s subwoofer pre-out to the input of your monoblock amplifier. Then, you will use a jumper RCA connected from the output of your bass processor and into the input on your monoblock amplifier. And that’s all it takes to wire your bass processor up, so you can start restoring the bass in your car audio sound system.

Equalizer Buying Guide

Parametric and Graphic EQ's Are Both Used to Clean Up Your Sound

 

Buying an Equalizer

What Does an Equalizer Do?

If you have ever wanted to have more precise control over the sound in your vehicle’s sound system, you might want to think about investing in an equalizer. The basic definition of an equalizer is that is allows you to fine tune the sound in your car to your liking. These adjustments that an equalizer allows you to make are for specific ranges of sound known as ‘frequency bands’. An equalizer will smooth out the frequency response of your system and help you eliminate unwanted distortion.

Why Add an Equalizer?

Clarity and balance are crucial pieces of your vehicle’s sound system, and just buying a set of speakers with a bigger power rating on them won’t necessarily achieve the perfect sound you’re looking for. If you want to have pinpoint control over your sound, you’re going to need to add an equalizer. To put it simply, adding an equalizer to your sound system will allow you tune your sound to match your preferences, as well as to the acoustics of your specific car. Most aftermarket headunits include a built-in equalizer. Higher end aftermarket stereos have customizable EQs, but many have EQ presets that are preprogrammed for specific music types. If you are planning on using an equalizer with your factory sound system, you can even add an auxiliary input.

An important note about adding an equalizer to your system, it is not designed to make your system louder or make your amplifier produce more power.

What Kind of Equalizer?

There are several different types of equalizers available for you to install in your audio system. The two most common EQ types are Parametric Equalizers and Graphic Equalizers.

Graphic Equalizer:Graphic Equalizers are the Simplest EQ Format

A graphic equalizer is the simplest (and standard) type of EQ. Graphic EQs are made up of multiple sliders or controls. Each slider or control functions to boost or cut a small section of the audio spectrum at a preset frequency (or band). A typical graphic equalizer will have between 5 and 12 slider controls on its face for you to tweak specific bands of your sound. Your typical 5-band graphic equalizer will have sliders for 5 fixed frequencies: low bass (25-30Hz), mid-bass (80-150Hz), midrange (1kHz), upper midrange (10kHz) and treble or high frequency (20kHz). Unfortunately, the width of each one of these bands is preset and cannot be adjusted.

Parametric Equalizer:

A Parametric Equalizer allows you to take the functions of a graphic equalizer a step further by allowing you to adjust the width of each frequency band you adjust. A parametric equalizer is capable of controlling 3 aspects of each frequency: the level, the center (primary frequency), and the bandwidth (range of each frequency). This gives you even finer control over the sound adjustments you make to your sound system.

 

What Else to Look For?

Adding an EQ to Your System Allows You to Fine Tune Your Sound

It is important to be aware of just how precise you plan on getting with your sound adjustments. The most common equalizers come with 7 adjustable bands, and while there is theoretically no real limit on how many bands an EQ can have, they typically max out at around 30 bands. The more bands your equalizer has, the more you can tune your sound. The potential downside to equalizers with more bands is that they are more difficult to tune and do not offer much benefit unless you have access to specialized sound testing equipment that can precisely identify any technical issues in your sound settings.

Depending on how serious you plan on getting, you may want to think about purchasing an equalizer with more bands whereas if you just want something basic that will still make your system sound good you are probably safe with sticking with something around the 7 band norm.
