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.

We shall now turn our attention to the H

ARMONICS

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 S

TEREO

V

ITALIZER

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

V

ITALIZER

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.

Finally, activate the S

P

turn up the S

W

IDTH

control to the 12h-position and note the soft spreading stereo image.

Switch V

A

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.
