How to operate the unit with an optional 5.1 ch decoder/AV matrix unit connected
A variety of materials are used inside a vehicle to manufacture the seats and windows, and
these materials absorb and reflect sound in different ways. The parametric equalizer lets you
adjust the peaks and dips of the frequency characteristics inside the vehicle to compensate for
these differences.
these materials absorb and reflect sound in different ways. The parametric equalizer lets you
adjust the peaks and dips of the frequency characteristics inside the vehicle to compensate for
these differences.
An “equalizer” is a function that corrects these peaks and dips in order to flatten frequency
characteristics. However, with a normal graphic equalizer, the median frequency and the Q
(sharpness and bandwidth) are fixed, so that when neighboring bands are corrected, there is a
limit to the amount of distortion in the peak and dip characteristics that can be corrected. A
“parametric equalizer” lets you adjust the median frequency, Q (sharpness and bandwidth)
and gain to variable levels, so that you can make fine adjustments to spot areas of the
frequency band.

Harmonizer
When original sounds are converted to MP3/WMA format,
frequency ranges that are not normally audible to the
human ear are compressed. The harmonizer can be used
to play back these compressed sounds at as close to their
original form as possible so that clear and powerful sound
can be enjoyed.

Loudness
The loudness control may be turned on the emphasize low
and high frequencies at low volume levels. Loudness
compensates for the apparent weakness of low and high
frequencies at low volume by boosting the bass and treble
levels.
