STEREO
5. A section within the STEREO VITALIZER with one of the most decisive
influences on the sound is P
ROCESS control. If you continue to turn the
P
ROCESS control up, more of the signal is added to the BASS and MID-HI TUNE
sections whilst dominant mid frequencies are reduced according human
hearing at the same time. The below sections contain more detailed infor-
mation on this aspect. Familiarize yourself with the sound changes before
deciding on the setting which sounds best.
6. We shall now turn our attention to the HARMONICS control. Note the
improved detail in the high frequency range, the further you turn the
control in. In practice, values between 4 and 6 have proved to be the most
common.
The H
ARMONICS are accentuated by the STEREO VITALIZER with equalizer
technology, unlike other procedures. Previously, so-called »Exciters«,
devices to generate harmonic tones, produced their harmonics with the aid
of a generator which mainly added type K3 and type K5 distortions to the
signal (odd harmonics of 3rd and 5th order). The familiar disadvantages of
this principle are as follows: although odd harmonics do add to the brilli-
ance of the audio signal to a significant degree, they tend to be somewhat
sharp, which leeds to hearing fatigue for listeners. Another pitfall is that the
distortions added were not part of the original signal.
The S
TEREO VITALIZER accentuates the harmonics which are also part of the
original signal! The H
ARMONICS filters are designed in such a way that even
and odd harmonics (K2, K3, K4, K5...) are accentuated equally. This makes
the processed signal more natural with a soft, silky-sounding top-end.
Once you have selected the setting for the
HARMONICS control you can sit
back to listen to the new sound image.
7. Finally, activate the SURROUND PROCESSOR turn up the STEREO WIDTH
control to the 12h-position and note the soft spreading stereo image.
8. Switch VITALIZER ACTIVE off to return to the original signal. If you now
say »I don't believe that« or »Booh«, you belong to the overwhelming
majority of those people who have ever heard a V
ITALIZER. It was this sound
impression which led to V
ITALIZER technology winning awards like the
»Golden Ear« from Europe's biggest »Audio« magazine for the most inno-
vative product in 1993.
