均衡器的调整（Equalizer adjustment）.doc

均衡器的调整（Equalizer adjustment） Now, the graphic equalizer used in the professional audio system is generally about 31 segments. The Q value of the push and pull potentiometer is constant, generally 1/3 octave, so whether it is lifting or attenuating a frequency, The bandwidth of the filter is always the same, the degree of frequency enhancement and attenuation is generally 618 dB, the most common is 12dB. The schematic equalizer passes the position of the push and pull keys on the panel, Can be very intuitive to reflect the frequency of ascension and attenuation. Commonly used professional graphics equalizer, frequency regulation range is generally 20Hz~20kHz, The frequency adjustment points are generally from low to high as follows: 20Hz, 25Hz, 32Hz, 40Hz, 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160Hz, 400Hz, 200Hz, 250Hz, 315Hz, and c., 500Hz, 630Hz, 800Hz, 1kHz, 1.25kHz, 1.6kHz, 2kHz, 2.5kHz, 3.15kHz, 4kHz, 5kHz, 6.3kHz, 8kHz,, 10kHz, 12.5kHz, 16kHz, 20kHz and a total of 31 frequency points, Because one of its main functions is to adjust the sound field in the room, it is also called a professional multi section schema room equalizer. Below I will own years of experience using the equalizer to write, I would like to refer to your reference: Adjust the sound field with an equalizer Among the three main functions of professional equalizer, adjusting the tone is the most basic and frequently used function, Even now, many sound engineers only know that the equalizer can adjust the tone without knowing the professional schema. The more important function of the room equalizer is to adjust the sound field and suppress the acoustic feedback. A very specialized way to tune the sound field with room equalizers is to adjust with the aid of a pink noise generator and a real-time spectrum analyzer. But most of us now the audio division is not possible to have these devices, only local materials, use of existing equipment to adjust the sound of, The simplest and most practical way is t
