The dotted line shows frequency responses for a soft Bass (SOFT) at varying
PROCESS and a
of 3.5 kHz.
The solid line shows the phase responses, which always drift only a few degrees if the PROCESS inten- sity is increased.
The diagram shows very clearly that the mid attenua- tion gets stronger as the PROCESS value increases.
STEREO VITALIZER alters the frequency spectrum in such a way that the balance is maintained between all frequency ranges even at varying monitor volumes. For the human ear, the sound is more pleasant and easier to perceive than the original. In other words, increasing the PROCESS value also increases the intensity of the

We consciously did without the generator principle of »Exciters«. The STEREO VITALIZER's harmonic filter does not add any distortions to the original signal, unlike with the generator principle. It extracts all the infor- mation it needs from the original signal. This significantly reduces the hearing fatigue effect on the listener. By influencing the phase relationship in an intelligent fashion, the harmonics which have been filtered out are emphasized with increasing addition expressed as a percentage. The effect significantly improves the speech intelligibility and the transparency. Old archived recordings sound fresh and silky again. The brilliance of any audio signal can be improved without it sounding sharp.
The HARMONICS filter derives its input signal from the original signal and the output of the
