Audio Adjustment <Equalizer>
The points when adjusting the equalizer curve
• Take the recreated frequency bands of the speakers into consideration when adjusting. For example,
when a speaker with a band between 80 Hz and 4 kHz is connected, adjusting the level in 50 Hz or
10 kHz will have no effect.
• Balancing the bass and treble is recommended. The bass tends to be lacking when no subwoofer is
connected. Adjust the treble to a lower volume to match the weaker bass and create a well-balanced
sound.
• Noises coming from the road make the bass seem weak while driving. If the level is below 100 Hz,
adjust to a slightly greater level to maintain superb sound balance while driving.
• When the sound is inadequate or excessive, it is recommended to set the levels after checking the
frequencies of the sounds in question by changing the peripheral frequencies to the maximum or
minimum.
