Parametric Equaliser - Eclipse CD8445E Owner's Manual

Various Settings

Parametric equaliser

A variety of materials are used inside a vehicle to manufacture the seats and windows, and because
these materials absorb and reflect sound in different ways, the parametric equaliser lets you adjust
the peaks and dips of the frequency characteristics inside the vehicle to compensate for this.

An "equaliser" is a function that corrects these peaks and dips in order to flatten the frequency
characteristics. However with a normal graphic equaliser, the median frequency and the Q (sharpness
and band width) are fixed, so that when neighboring bands are corrected, there is a limit to the amount
by which distortion in the peak and dip characteristics can be corrected.
A "parametric equaliser" lets you adjust the median frequency, Q (sharpness and band width) and gain
to variable levels, so that you can make fine adjustments to spot areas of the frequency band.

In the deck's normal mode, 7-bands can be adjusted with a parametric equaliser. In the pro mode, 5
bands in the high frequency range and 5 bands in the mid to low-frequency ranges can be adjusted with
a parametric equaliser, when using 3-way speakers. When using a four-speaker system, 5 bands for
the front and 5 bands for the rear can be adjusted separately.
