Description:

A stereo equalizer is an electronic device that can adjust the amplification of various frequency components of electrical signals separately. It compensates for the defects of speakers and sound field by adjusting electrical signals of different frequencies, and compensates and modifies various sound sources and other special Function, the equalizer adjusts the high-frequency, intermediate-frequency, and low-frequency electrical signals separately to improve the sound quality. Graphic equalizer, through the distribution of push-pull keys on the panel, can intuitively reflect the balance compensation curve that is called up, and the boost and attenuation of each frequency are clear at a glance. It uses constant Q technology, and each frequency point has a push-pull potential. Regardless of raising or attenuating a certain frequency, the frequency bandwidth of the filter is always the same. The graphic equalizer is simple in structure, intuitive and clear, so it is widely used in professional audio.
