Functions of the graphic equalizer
Functions of graphic equalizer
Compensation for the audio
characteristics of the listening room
The listening room may contain several objects. Some
of them reflect sound and some absorb sound , thus
the sound reaching your ears is considerably affected
by these objects.
In such cases, the graphic equalizer can be used to
adjust the frequency response of the room for a flat
response from low to high frequencies.
¶Low frequencies are absorbed by beds, chairs, etc.
¶High frequencies are absorbed by curtains, screens,
etc.
¶The room structure can cause the low frequencies to
be unclear, or the sound level to increase or decrease
depending on the frequency.
Adjustment of sound to your individual taste
When the reproduced sound contains several musical
instruments and voices, the graphic equalizer allows
you to enhance or attenuate the sound of specific
instruments or voices.
Super bass range (40 Hz ~ 63 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 (98 Hz ~ 160 Hz)
Usually, the listening room resonance frequency is in this range.
To eliminate bass resonance, move this control down.
Mid-bass range (250 Hz ~ 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 (625 Hz ~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 (1.5 kHz ~ 2.5 kHz)
This range is related to stimulus and metallic sound. When this range
is well compensated, vivid sound can be obtained.
High range (3.9 kHz ~ 6.3 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 (10 kHz ~ 16 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.
