Equalizers - What they are and how to buy them Equalizers have been around since the 1970’s, the original ones were analogue equalizers. These were the very first stereo equalizers, designed with a very simple idea, which was to pass the Alternating Current (AC) signal though capacitors and inductors to balance sound through speakers. Those first audio equalizers became the grandparents of today’s modern digital sound technologies. Stereo equalizers became more sophisticated in their manipulations of sound and the development of graphic equalizers allowed the average user to visualize the music and adjust the controls. When these audio equalizers where first developed they had sliding controls but that fixed the frequencies and limited the precision needed for digital. Today many graphic equalizers for the home have automatic controls but still allow users to visualize the music. Most graphic equalizers are now used in recording studios, bands, and high-end sound systems. Today, many computers have audio equalizers built into their systems when you go into the sound software they often make the screen look like a graphic equalizer.

Equalizers are important is modern music they are used to change the frequency response while in the recording studio. From there, music lovers use stereo equalizers to smooth sounds from speakers of lower quality, balance higher quality speakers to bring out crystal sounds or balance multiple speakers in a surround sound system. Car equalizers with a stereo are essential. Without a good car equalizer, sounds would be unbalanced because of the number of speakers installed inside the car. By reducing the base frequencies in the music, cars get a crisper sound and a reduction of echoing. Using a car equalizer is necessary for any quality car sound system. When buying an audio equalizer there are a number of things to consider. Compatibility is important. Music lovers don’t want to purchase a stereo equalizer designed for a TV surround system and use it with a high end stereo. They also don’t want to purchased a stereo equalizer and use it in a car. Each of these equalizers specially designed to control sound in specific areas. Ease of use should be another consideration when buy an audio equalizer. Many stereo equalizers are automatic or graphic equalizers, which are easier to learn and to adjust sound. Users, who are not experience with the use of an equalizer, may wish to avoid purchasing the more complex parametric processors. These equalizers manipulate multiple channels and should only be used by advanced music lovers. Finally, price and quality are important considerations when buying an audio equalizer. By doing research and shopping around buyers can find the right stereo equalizer. Prices vary and sometimes spending a lot of money does not necessarily mean purchase of the best equalizer. Make sure to read the equalizer’s manual. Unlike some products, equalizers are all different in their use and the manufacturer will know best how to get the best sound from it. Sound technicians determine the original manufacturer settings and buyers should not change any setting until they fully read the manufacturers suggestions.
