Sound equalization
  • Super bass range (60 Hz)

    • When this control is moved up, the bass instrument (double bass, . bass drums, or pipe organ, etc.) sound is increased.
    • When the super bass sound is boomy, move this control down.
  • Bass range (150 Hz)

    • Usually, the listening roam resonance frequency is in this range.
    • To eliminate bass resonance, move this control down.
  • Mid-bass range (400 Hz)
    This range is the basis of music. Whether the sound is rich or not, depends on this range. When the playback sound is not so good, move this control up.

  • Mid range (1 kHz)
    When this control is moved up or down, the baritone or soprano voice is emphasized/de-emphasized. This range is related to the “presence” of music.

  • Mid-high range (2.4 kHz)
    This range is related to stimulus and metallic sound. When this range is well compensated, vivid sound can be obtained Copvfish

  • High range (6 kHz)
    This frequency range is related to the hardness of the sound. When this control is moved up, strings or brass instruments, such as flutes or piccolos, are emphasized. When the control is moved down, the sound will be more soothing.

  • Super high range (15 kHz)
    This frequency range is related to the details of the music. When this control is moved up, super high frequency instruments, such as triangles or cymbals, are emphasized, resulting in wide sound and echoes.
