Description：

 Besides loudspeaker, amplifier and mixer, peripheral equipments also play an important role in professional audio system. The aim of professional signal processing is to optimize the sound effect and protect the sub-equipments, with all kinds of modification and polishing to the audio signals. Typical equipments used for professional signal processing include: Equalizer, Compressor, Effecter, Exciter, Frequency shifting processor, etc.
　　Equalizer is a kind of audio equipment which can be used to adjust the frequency response curve. It can compensate the frequency deficiency in signals caused by various reasons, meanwhile avoid excess frequency in the signal. For example, equalizers can restrict the low frequency voice ranged 60~250Hz as well as high frequency noise ranged 6~12kHz. Equalizers can also be used for volume adjusting and timbre glorification. The original meaning of equalizer is to equalize the unbalanced frequency characteristics with the opposite frequency characteristics.
