Equalizer trends

Use of digital filter consisting of equalizer is called digital equalizer, digital equalizer to make graphic EQ, parametric EQ can be made, and you can make both EQ, it not only each performance index superior, easy to operate, but also can also store multiple uses balanced frequency response characteristics for different programmes require selection, you can store up to 99 frequency response curve. SONY's SRP-E300 is a versatile 2-channel digital equalizer with 10 parametric Equalization and 29 illustrations balanced, or independent work with limiter and noise gate function, high-precision 48kHz sampling, 20-bit linear modulus/DAC; with analog and digital input/output; RS-232CC interface for external control, that it will phase out ordinary analog equalizer, is a professional audio amplification areas have very high performance-cost ratio products. Sound production: objects propagation through the air waves, vibrations, caused by a vibrating membrane for auditory senses. Human auditory 20HZ--20KHZ sensitive 1KHz--4KHz most sensitive 3.4KHz human voice male 80Hz--500Hz female 100Hz--1KHz phone 200/300--3KHZ TV 100HZ20--250 LOW (LF) 250--2KHz MID (MF) 2kHz--4KHz MH 4KHz--20KHz High (HF) 50Hz upgrade 2-3db, gives a strong sense of shock, enhanced sound 60Hz, to striking sense, not much lifting 50, 100Hz is AC frequency, upgrading is carefully 100--200Hz attenuate 3-6db, legible 100Hz following attenuation 6-12db, can increase the clarity of the language--300Hz promotion 100 3-5db increasing the richness of the music, for example: Moderator Lixiang 250--500Hz upgrade 3-6db, thick, warm for example: Moderator Zhao Zhongxiang 300--500Hz upgrade 4-5db increasing the intensity of the music to sound 330Hz gives a solid feeling of fullness the bass, but not soft, too, will have the effect of the "bathroom" effect on the intensity of the 500Hz, upgrading 2-4db gives people a sense of closeness and depth--3KHz lifting 800 3-6db, penetrating more suitable for the enhanced. also TECHNO, TRANCE now, HARD BASS, PROGRESSIVE but 800Hz Office upgrade to special care, the frequency increase would be noisy and narrow sense 1--1.5KHz upgrade 4-5db sound brightness and levels have increased, the tone is bright and smooth, especially for boys is especially apparent in the 2-2--4KHz upgrade adds voice 4db brightness 3KHz--10KHz raise 3-6db, tooth sound, enhanced presence, but also some not suitable for lifting 3KHz upgrade too much will produce auditory fatigue 4KHz Department should not mention 5KHz upgrade failure by 6db makes sound volume seems to increase the 3db, such as attenuation mixed sound 5KHz component, makes sound sense become far distance 6.8KHz upgrade too high results in scream, particularly attached microphone PA system causes high frequency feedback whistling 8KHz above a little upgrade to enhance the sound levels and color are more than a band 10KHz preferable not to upgrade or not to upgrade, to control in 3db, if they feel a sense of high frequency content, can be balanced after receiving tone actuator to compensate.
