Summary
The usual volume adjustment is to adjust the overall amplitude of the sound wave (that is, the overall volume), while the equalizer adjusts the volume of a certain part of the frequency band (or the whole frequency band) of the sound wave. The debugging of the equalizer needs to be based on the vocal characteristics of the human voice. Because everyone's voice is different, there is no unified standard for specific debugging.
What is an equalizer?
Recently, as soon as the new equalizer EQ231 was put on sale, many customers came to inquire about the purchase. Some customers like its cool LED display, but they don't know what the equalizer is used for. To this end, Sinbosen popularizes the equalizer for you!
Equalizer is an electronic device that can separately adjust the amount of electrical signal amplification of various frequency components. It can compensate for the defects of speakers and sound field by adjusting the electrical signals of various frequencies, compensate and modify various sound sources and other special effects. Some people may see that the mixer also has an equalization function, but the equalizer on the general mixer can only adjust the electrical signals of high frequency, intermediate frequency and low frequency respectively.
The adjustment of the equalizer can be simply understood as: the usual volume adjustment is to adjust the overall amplitude of the sound wave (that is, the overall volume), while the equalizer adjusts the volume of a certain part of the frequency band (or the entire frequency band) of the sound wave. Sinbosen's EQ231 equalizer can adjust 31 bands of frequencies.
How to adjust the equalizer to achieve the best effect?
The debugging of the equalizer needs to be based on the vocal characteristics of the human voice. Because everyone's voice is different, there is no unified standard for specific debugging. In general, the role of the equalizer is mainly to avoid weaknesses and promote strengths.
We can perform scalpel-like cutting of all unnecessary frequency bands for vocals, such as high and low cuts, sibilance attenuation, hum attenuation, and box sound attenuation. There is also the need to give full play to the different sound characteristics of each person, and appropriately enhance the characteristic frequency band. The more common operation is that 2K improves a little clarity, 5K improves a little sense of presence, 8K improves brightness, and 10K or more is gloss and color.
Remember, don't get addicted to boosting the high frequencies. "Equalization, equalization!" Excessive boosting of any one frequency band will make our vocals unbalanced, and then lose the meaning of equalization.
The following describes the adjustment method of the equalizer frequency band:
If adjusted properly, the sound performance is strong and powerful. Too much boost can muddy the music. Mainly used to control the sound of bass drum, organ and bass.
This is the basic frequency band of the sound. This frequency band accounts for a large proportion of the entire audio energy and is an important component for expressing the style of music. When adjusted properly, the bass is relaxed and the tone is plump and soft; if the adjustment is insufficient, the sound performance is quite thin, and if the adjustment is too high, the sound will be dull and the brightness will decrease.
The human voice is in this frequency band. When the debugging is insufficient, the singing sound will be drowned out by the background music, and the sound will appear soft and weak. When properly tuned, it feels powerful. Excessive boost can stiffen the bass and affect the clarity of the sound.
This band contains the lower harmonics and overtones of most instruments and is the characteristic sound of typical snare drums and percussion instruments. When debugging properly, the sound is transparent and bright, and when debugging is insufficient, the sound is hazy. It produces a phone-like sound when boosted too much.
This is the characteristic sound of strings, that is, the friction between the bows and strings of the strings. The penetration of the sound decreases with insufficient tuning, and the recognition of language syllables is masked by over-boosting.
This is an important frequency band that affects the layering of the sound. Excessive adjustment and improvement will make the sound of the piccolo and flute stand out, the sibilance of the language will increase, and the timbre will be hairy.
When adjusted properly, the metal sense of the grand piano and the upright piano is highly transparent, and the rhythm of the sand bell is clearly discernible. Excessive tuning will distort the sound and easily burn the high-frequency speaker unit.
