SRS Circle Surround II (CS II)

Surround sound is produced by combining The CS II (SRS Circle Surround II) mode enables 4-speaker surround sound. The system achieves surround sound by combining SRS TruBass, which uses the difference between two different frequencies to boost bass tones, and SRS Circle Surround, which uses 2ch (L/R) correlation to expand the sound.

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.

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.
