Any equalizer can be divided into three types of frequencies: high, mid, low. Each type correspond to several controls corresponding to a level of Hertz. To adjust the equalizer, turn up the music at a comfortable volume. First of all, remove the overemphasis of any frequency, as expressed in the rales. The sound should be clean and clear, not cutting ears. It should also be guided by personal taste. For example, someone who likes soft bass, someone tough, someone very low. In all cases, adjust a comfortable sound levels in all frequencies.
Adjust the equalizer depending on music. If there is a party where guests like pop songs, boost the midrange to highlight the voice of the singer and singing. If, for example, the bulk of the music will consist of dance beats, MIDs, instead, to lower and raise the high and low.

But you can align the equalizer in another way, if, for example, in the special room acoustics and layout. Thus, to properly adjust the equalizer, you can follow the examples of experts in sound, and can trust your ears. After all, in the end, the music you listen to and the sound should be like, first of all, you.
