@ Sound equalization
e Super bass range (40 Hz ~ 63 Hz)
When this control is moved up, the bass instrument (double bass,
bass crums. or pipe organ, etc.) sound is increased.
When the super bass sound is boomy, move this control down.
e Bass range (98 Hz ~ 160 Hz)
Usually, the listening room resonance frequency is in this range.
To eliminate bass resonance, move this control down.
e Mid-bass range (250 Hz ~ 400 Hz)
This range is the basis of music. Whether the sound is rich cr
good, move this control up.
e 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.
-
not, depends on this range. When the playback sound is not so.
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 considerabiy 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.
e High frequencies are absorbed by curtains, screens, etc.
e 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.
=
e Mid-high range (1.5 kHz ~ 2.5 kHz)
This range is related to stimulus and metailic sound, When this
range is well compensated, vivid sound can be obtained.
e 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.
e 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.
