使用均衡器调整音色的方法（Method for adjusting timbre by using equalizer） 1. frequency adjustment good audio pitch and fullness, firmness: under normal circumstances the frequency range of 20Hz-315Hz is divided into low-frequency. The focus of this section is to adjust the main pitch audio part, like a Pyramid, no basic part will not have the spire part, so bass the frequency adjustment is very important. In concrete operation: A.25Hz 32Hz, the two frequencies are basically complete decay, because now many speakers have bass frequencies down to this band. B.40Hz, 50Hz these two frequencies happen to be the current 220V AC frequency, in order to reduce the power supply part of the interference, we generally put the two frequency attenuation of about 5 dB C.63Hz, 80Hz, 100Hz, these three frequencies determine the fullness of the sound source, generally do not make big ascension and attenuation D.125Hz, 160Hz, 200Hz, 250Hz of the four point source determines the strength and stiffness, improve too much of the sound attenuation are too stiff, sound vague, virtual, so that several points in the low frequency band is the key. The low frequency need to pay attention to a point of the 3 dB is added to the bass part and the load of the power is doubled, so the adjustment must be careful attention should be paid to the tone, but also take into account the sound field, but also the capacity of power amplifier. 2. if the adjustment of each stress source of the two or three overtone and rounded, bright degree: under normal circumstances the frequency range of 400Hz-2.5KHz is divided into intermediate frequency, we know that the main source of the most part will pitch in the bass part, then the 2 overtone of them, the 3 overtone, four overtone...... Will be in the audio section; there are some sources due to a higher frequency, the main part of pitch in the band. In this period of adjustment is the focus of most of the source of the good two or three overtone and timbre rounded, bright degree
