When working with the equalizer, it is very important to understand that amplification of a frequency band leads to an increase in the overall level of the audio signal, and excessive amplification of the bands can often lead to distortion of the audio signal. In this regard, the weakening of the “unnecessary” frequencies often gives a better result than the amplification of the “necessary”. Therefore, the equalizer should be used very carefully and not used if there is no obvious need for it.
Equalizers have a wide range of applications. Their main purpose is to obtain an adequate (linear) sounding of the source material, the frequency response of which can be distorted due to shortcomings of acoustic systems, inter-unit processing devices, room parameters, etc. Continue reading
