Eclipse - Fujitsu Ten CD5000 Position selector, SRS Circle Surround II CS, Parametric equalizer

Various Settings

Position selector

When the position of the listener's seat is selected, the time taken for the sound to travel from the speakers to the listener can then be adjusted in order to obtain a more natural sound orientation. This main unit allows up to four different positions to be set.

SRS Circle Surround II (CS II)

SRS Circle Surround II delivers a unique surround sound experience equivalent to 5.1 channels over only four speaker system owing to the three combined effects:

Circle Surround decoder that enables surround sound to 5.1 channels from any stereo format (L/R or Lt/Rt including surround sound information), SRS TruBass that makes us feel the lost fundamental bass sound through psychoacoustic response of the brain that occurs when two adjacent harmonics are carefully selected and amplified, and SRS FOCUS that elevates the sound image vertically resulting from a patented digital sound processing technology based on the HRTF (Head Related Transfer Function) theory.

DSP

The DSP function reproduces the sensation of various factory set performance environments by adding reverberation to the music being played.

Parametric equalizer

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 equalizer lets you adjust the peaks and dips of the frequency characteristics inside the vehicle to compensate for this.

Dip

Low [Frequency] High

An "equalizer" is a function that corrects these peaks and dips in order to flatten the frequency characteristics. However with a normal graphic equalizer, 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 equalizer" 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.
