Audio Adjustment <Equalizer>
About the Equalizer Menu
One important factor for creating quality sound is the correction of disturbances in fre-
quency characteristics within the complex shape of a vehicle interior.
Reflected sounds have a strong effect on direct sound in a vehicle because of the vehicle’s
shape, the confined space, absorption of sound by the seats and reflection from the win-
dows. All these cause disturbances in the frequency characteristics. Such disturbances will
be apparent as reduced sound quality.
Graphic equalizer is used under this system. The graphic equalizer adjustment corrects dis-
turbances in frequency characteristics and creates a smooth sound quality.
• As installation conditions differ for the left and right speakers, different corrections must
be made for each. This system’s graphic equalizer is able to correct the left and right
speakers separately.
