专业音响 - c-mark 如何灵活使用调音台上的均衡器（Professional audio - c-mark how to flexibly use the equalizer on the console） How to flexibly use the equalizer on the console One function of the mixer is the major modification of timbre, and now the mixer (except some high-grade) tones are almost without exception three segment equalizer: high frequency and low frequency and a frequency equalizer, namely high frequency lOkHz or 2kHz, 80Hz or 100Hz bass, some are a English. HI and LO allow you to guess, but guess the above parameters will be pretty close. If is the parameter adjustable, for if people use the general parametric equalizer, know the frequency at a button frequency, then the button above to enhance or attenuate it. But the high bass knob some careless sound and repeat, see the bass button on the 80Hz or 100Hz that this channel is in the electric guitar what, think it is no use this frequency cut left, see the treble button on the lOkHz or 12kHz will toggle to the left side. To think that this channel is electric bass can also be this not completely mistaken, because it involves the understanding of the characteristics of the three segment equalizer, the mixer on the general frequency parametric equalizer is a band-pass filter with a high Q value, narrow frequency band, it is a peak frequency characteristic, frequency band is very narrow, but the frequency can move around. With the sweep knob with a lifting and attenuation knob, and the treble and bass knob is a low Q value, wideband bandpass filter, frequency curve is scaffolding, which mark the 80Hz bass knob refers to its center frequency, it is 80Hz the center of a region, it may extend to the upper limit of 300Hz, and the lower limit may be extended to 20Hz. So is the treble knob, 10kHz or 12kHz as its center frequency, its extension may reach 16kHz, the extension may be 5~6kHz, so indiscriminate all it will decay or increase is extremely wrong, because it is not a point you get, but a sound area. I sometimes feel in
