For your stereo or home theater system for its large can be frustrating, but it is a component that can really help your music and movie sound ... magic audio equalizer. An equalizer allows you to control different parts of spectrum. Being able to adapt certain "bands" or groups of frequencies to adjust the sound in relation to the system that plays in the room or played in.
An equalizer is liketone control in a home or car stereo. In fact, the tone control and EQ. Low adjusts the low frequency half adjusts the mid frequency and treble all the high frequencies. In this case, the tone controls do a 3-band equalizer ... low, medium and high.
Most have separate audio equalizer 7-band, 15 bands or 31 bands of equalization. The bands, the more control you have on the sound. In most cases, 7 to 10 bandsenough for a stereo equalizer. Note, an audio equalizer is generally separate controls for the left channel and right audio channel. Thus, a stereo 15-band equalizer is composed of 15 bands for the left channel and 15 bands for the right channel. Like most music and movie audio is already mixed and mastered, the adjustments you make in the equalizer must be made for both channels to maintain adequateimage.
The room from your stereo or home theater is in your system and how it shapes what will determine the best equalizer to your system and what is the best equalizer settings. A well-designed room and speaker placement good sometimes eliminate the need for an equalizer at all. But most stereo systems and home theater will require equalization.
Sometimes, the fourth its too "boomy". In this case, is reduced at low frequenciesmaking thud. Try to take some 250 Hz or 400 Hz and see how it sounds. The frequency bands are indicated on the equalizer. Each regulator will have a number that is the cursor of the frequency band is adjusted. After only a little time spent listening and adapting, you will be able to identify a frequency problem and an appropriate adjustment in the equalizer. Do the voices sound a bit weird? Try a drop of 2.5 kHz to soften the voice and get rid of this "horn", sometimeslisten to the voice frequency range.
Of course, the sound will change with every song and every movie seems a little different, but the addition of a home audio equalizer can "tune" the system to compensate for problems of acoustics and room to shape the sound of components to help others keep the sound as natural as possible, which should be your main objective to create a sound system.

Equalizers are signal processors that help you in finalizing your audio setup. Equalizers are used to fine tune a sytem's sound not to fix major setup mistakes. It is something you should set once to help you overcome acoustic problems in your car. Avoid the funny habit of adjusting the equalizer after each tune.
But that's another issue. Let's get an understanding of equalizers so you will be in a position to make more informed choices. After all, there won't be any equalizer to tweak endlessly if you don't have one.
There are graphic equalizers and parametric equalizers. A graphic equalizer has fixed frequencies that you can fine tune. But a parametric equalizer has adjustable frequencies. You dial in on the frequency you want to fine tune and then start fine-tuning.
If you're not experienced in audio processing, you're better off with a graphic equalizer. This is because it already has pre-Fixed frequencies (and this frequencies are usually the most important given the number of bands it has). This makes it a lot easier for you to start the fine-tuning process.
The parametric EQ gives a lot more control but is also a lot nore complicated.
There are also mono and stereo equalizers...
A stereo equalizer has two inputs and two outputs while a mono equalizer has just one input and one output.
This means that a stereo equalizer can be used for both channels of your audio setup. But this point has to be stressed...
You cannot set different controls for each of the channels if you're using a stereo equalizer. You can do that, though, with mono equalizers. However, you'll need two.
A mono equalizer (If you use two in your setup) also gives you a lot of room to compensate for a few things like delays and certain problems caused by poor speaker placement.
It is quite more expensive buying two mono EQs. So this is not an option for the fiscally challenged. The setup process is also more involving. If you're less technically inclined, you may as well go for the less complicated stereo equalizer. At least, you know what you shouldn't expect.
Lastly, there is the issue of whether you should go for a high level or low level output equalizer. I'm not going into how these work here. What I'll say, however, is that low level output equalizers are far better but are also a lot more expensive.
So if price is a big issue, go for what you can afford? Not really! Most audio specialists will recommend you do WITHOUT an equalizer in your setup if you are not ready to get a good low level equalizer.
