How to set the equalizer bass with seven adjustment bars?

The equalizer setting of seven adjusting levers should push 63 up to the top. There is also a total increase attenuation from-12db to+12db. This is useful for all sound bands.

Equalizer adjustment method:

Heavy bass: 20Hz-40Hz, with strong sound when appropriate. Can control thunder, bass drum, organ and bass. Excessive ascension will make music turbid.

Bass: 40Hz- 150Hz, which is the basic part of sound, and its energy accounts for 70% of the whole audio energy, and it is an important part of expressing music style. When appropriate, the bass is relaxed and the voice is full and soft. When it is insufficient, the voice is low, 150Hz. When it is raised excessively, it will make the sound dull, reduce the brightness and enhance the nasal sound.

Midrange: 500Hz-2KHz, including the lower harmonics and overtones of most instruments, is the characteristic sound of snare drum and percussion instruments. The sound is clear and bright when it is appropriate, and hazy when it is insufficient. Excessive lifting will produce a sound similar to a telephone.

Treble: 7KHz-8KHz, which is the frequency that affects the sound layering. Excessive promotion will make piccolo and flute sound prominent, the tooth sound of language will be aggravated, and the timbre will be hairy.

Extremely high sound: 8KHz- 10KHz. When appropriate, the metal permeability of triangle iron and vertical iron is high, and the rhythm of sand clock is clear and distinguishable. Excessive lifting will make the sound unnatural and easily burn out high-frequency units.
