What Does A Digital Bass Processor Do?
Posted on November 11, 2011 | Speakers.
If you are to look at any system that has a serious car stereo in it you will most likely notice that most have a digital sound processor. The first time I saw one of these I thought it was just an overpriced bass boost, and that my current amp would do basically the same thing. Little did I know that a bass processor is much more than a bass boost.
A bass processor is installed before any crossovers or signal processors. So it would be hooked up right after your in dash unit. Always install before your crossover. At first you might think that a bass processor would be just for bass heads. This is not the case a bass processor can also improve the low end sound of all music from classical to rap. So what exactly does it do?
A good bass processor contains a circuit that accurately recreates and injects low frequency information back into the signal, giving your bass more impact. A bass processor will also allow you to customize this low end power to your specific vehicle. It does this by allowing you control the para-bass functions. What this does is allows you to adjust the sweep and the width of the bass.
The sweep will let you pick a certain frequency you want the bass restoration circuit to maximize. Having a lower sweep the bass will be centered around lower frequencies. While having the sweep higher means it will be centered around a higher frequency. While the width allows you to control how wide of a frequency range it will effect. If you have the width low the bass will be centered around a smaller frequency range, and turning this up higher will increase the frequency range.
So with all this bass processing going on you might be worried about your expensive subwoofers. I know that is something I was worried about when I first installed a “epicenter” by Audio Control a popular bass processor. I was mainly worried about the subsonic frequencies that can damage your stereo equipment.
If you look at any good bass processor will come with what is called subsonic filter. Subsonic frequencies are those that are not audible to the human ear. Sound frequencies that are below 20Hz are considered subsonic. A good bass processor will have a subsonic filter that will make sure you don’t waste your car stereo’s power on this subsonic information and will make sure you are putting all of your systems power to good use.
A subsonic filter is a huge feature to being able to fine tune your bass response. On most systems setting this filter at 33Hz will be good. If you want to protect you’re your speaker system even more though you can try a higher frequency. Often a higher frequency will sound louder and cleaner.
So whether your interest is in Beethoven’s kettle drums, Miles Davis’ trumpet, or the percussion of rap music, a digital bass processor will restore those long lost bass notes.
Car Stereo Systems – Amps, Subs, Speakers And CD Players

In the case of car audio, many contemplate constructing a well-balanced system, usually never. The most vital part of your music system is in fact managing the various highs, mids and lows, getting them to circulate beautifully inside of the car, collectively. This is going to allow you to hear the finest depth, every detail, your tunes can give.
CD receivers, for brand new vehicles, might already include a variety of options needed for you to enjoy tunes. They may possibly employ a 3.5mm front input jack which you can connect your portable songs player. Recent cars are currently offering decks that offer increasingly more ways for you to enjoy tunes.
Whenever you have an older vehicle, odds are, the preferred feature to choose to listen to music is going to be the FM radio, and some might certainly possess a CD player. Generally, these outdated receivers possibly will not deliver sufficient power for upgraded speakers, in case you want to change out the older speakers. The right route is always to replace your factory deck with an upgraded deck. This will certainly offer you a lot of songs playing choices together with improving power output to completely new speakers you will install.
Speakers in differing cars come set up offering diverse size speakers. For anyone who is uncertain which size speakers you may have, easily research the vehicle make, model and year to discover which size speakers your car has.
Do not be selfish with the speakers. In case you’re upgrading the front speakers, switch out your back speakers at the same time. It’s important to offer good music for your rear passengers as well.
If you’re searching for a louder sound system, you should purchase a 4-channel amp to power the four speakers installed in the front and back. Whenever you pick out your speakers, don’t forget to pay consideration to the RMS rating. The RMS rating will be the amount of watts the speaker will handle consistently. Whenever all four speakers are identical and handle 50 watts RMS each, buy an amp that offers 50 watts RMS for each channel.
When your speakers are diverse sizes for the front and back plus handle differing RMS ratings, by way of example, your front 4-inch speakers handle 40 watts RMS and the 5 1/4″ rear speakers handle 65 watts RMS, select a 4-channel amplifier that delivers 40 watts RMS per channel. Each speaker will definitely be loud enough and you simply are not going to have to be concerned with damaging the smaller speakers.
Just one sub will probably be good when you’d like to increase low frequency that plainly is not presently present. Your manufacturer speakers might actually sound fair, however when you turn the bass high, you are far from satisfied with the distortion from the speakers.
Get a subwoofer which could handle 150 – 300 watts RMS. This should be quite a lot of bass for virtually any factory system. In case you choose a subwoofer that can handle 200 watts RMS, make sure to suit it using an amplifier that delivers 150-200 watts RMS – whether it’s a single channel amplifier or you decide to bridge a 2-channel amp in 1 channel operation mode.
Should you have upgraded your speakers and purchase a 4-channel amplifier to be able to power them, take into consideration buying a subwoofer which could handle far more power. Typically a sub which can handle 500 watts RMS will supply quite a lot of bass for a system applying a 4-channel amp to power speakers in the front and rear.
If you need far more bass, you could simply install two subwoofers. This will move double the amount of air, generating twice as much bass. If trunk space isn’t a problem, a pair of subs will be fine.
For everyone seeking loud music, you will require an amplifier or multiple amps. It is wise to seek out an amp after you pick speakers or a sub you plan upon using. This will be for the reason that you must learn how many watts RMS the speakers and subs are equipped for. This will allow you to properly match an amp for the speakers as well as for your subwoofers.
Once you’ve got the components installed, turn the gain control dial on the amplifier for your subs down which means that there is no bass. Turn your deck up to around 75% and carefully turn the gain control dial up on the amplifier for the speakers until the loudest, but clearest sound is played through your speakers without distortion.
You should not get worried with regard to bass from your speakers. You should definitely have the bass turned down on your deck to an even 0 or a negative amount. You want the speakers playing all of the mids and highs loudly and clearly, along with almost no bass.
Now proceed to your car audio amplifier for the subwoofers and steadily turn the gain control dial up, and keep your receiver at about 75% volume with all the speakers performing. Carefully continue turning the dial up until the bass has quite nicely harmonized with the mids and highs of your speakers, however, without overpowering them. One or two minutes of adjustments and you’ve definitely made a well-balanced music system.
