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.
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.
