The development trend of the equalizer


An equalizer composed of a digital filter is called a digital equalizer, a digital equalizer can be used as a graphic EQ, a parameter EQ can be made, and an EQ can be made of both, which not only has excellent performance indexes. It is easy to operate, and can also store frequency response equalization characteristics for multiple purposes at the same time, which can be used for different program requirements, and can store up to 99 frequency response characteristic curves. SONY's SRP-E300 is a versatile 2-channel digital equalizer with 10-band parametric equalization and 29-segment graphic equalization. It can work simultaneously or independently, with limiter and noise gate functions, high-precision 48kHz sampling, 20 Bit linear analog/digital to analog conversion; with analog and digital input/output; RS-232C C interface, can be used for external remote control, its appearance will gradually eliminate the ordinary analog equalizer , is a professional audio sound reinforcement field A very cost effective product.

The generation of sound: the fluctuation of the object through the air, causing the vibration of the eardrum, and the sense of hearing can be obtained.
Human ear hearing 20HZ--20KHZ sensitive 1KHz--4KHz most sensitive 3.4KHz
Human voice male 80Hz--500Hz female 100Hz--1KHz
Telephone 200/300--3KHZ
TV 100HZ
20--250 LOW (LF) 250--2KHz MID (MF) 2kHz--4KHz MH 4KHz--20KHz High (HF)
50Hz raises 2--3db, giving a strong sense of shock
60Hz boost, strengthen the intensity of the sound, give people a sense of shock, not to improve
50,100Hz is the frequency of the AC, the promotion is cautious
100--200Hz attenuation 3-6db, improved clarity
Attenuation of 6--12db below 100Hz can increase the clarity of the language
100--300Hz upgrade 3--5db to increase the fullness of music. For example: host Li Xiang
250--500Hz Lift 3-6db, thick, warm, for example: host Zhao Zhongxiang
300--500Hz increase 4--5db to increase the intensity of music
330Hz gives a solid sense of sound to make the bass soft and full, but it is not easy to increase too much, it will produce a "bathroom effect"
500Hz has a great influence on the strength, and the 2-4db is enhanced to give people a sense of intimacy and depth.
800--3KHz Lifting 3-6db, penetrating power is enhanced. It is also more suitable for the current TECHNO, TRANCE, HARD BASS, PROGRESSIVE but the 800Hz lifting should be especially cautious. This frequency will be noisy and narrow after lifting.
1--1.5KHz improves the brightness and level of the 4--5db sound, and the sound is bright and smooth, especially for male voices.
2--4KHz boosts 2--4db to increase vocal brightness
3KHz--10KHz improves 3-6db, tooth tone, enhances the sense of presence, but some are not suitable for promotion
Excessive 3KHz boost will cause hearing fatigue
4KHz should not be mentioned
5KHz boosting 6db can increase the volume of the sound by 3db, such as attenuating the 5KHz component of the mixed sound, which will make the distance of the sound farther.
If the 6.8KHz boost is too high, screams will occur, especially if the microphone is connected to the sound reinforcement system, which will cause high frequency feedback whistling.
A little boost above 8KHz can enhance the sound level and color
It is best not to increase or exceed the upper limit of 10KHz. It should be controlled within 3db. If you feel that the high frequency band is not enough, you can add the tone exciter to compensate after the equalization.
