SPL STEREO VITALIZER® JACK

The Stereo Vitalizer

®

Jack represents the entr y
version of the Vitalizer Program EQ line from SPL.
It is used primarily to shape the sound of indi­vidual instruments and optimise mixes utilizing
established psychoacoustic principles of human
hearing. Its outstanding sound characteristic sand
extremely effi cient method of operation makes it
an indispensable tool in the fi elds of recording,
mixing, mastering, digital signal processing and
sound amplifi cation, where it is the reference for
sound optimising.

The SPL Vitalizer technology

The Vitalizer “un-covers” sounds by means of
a slight time shift of the signals as a function of
their loudness. Soft sound components that were
masked by louder ones are thus emphasized – the
smallest details become clearly audible and create
a life-like atmosphere, since the differentiated
reproduction produces a more natural sounding
result. Furthermore the entire sound is ideally
adjusted for our hearing capabilities. The sound
material is perceived as being more transparent
and the sense of loudness is increased while
avoiding listener fatigue.
Note: The Stereo Vitalizer Jack is not an “E xciter”!
In processing the sound all the information is
taken from the original signal. No distor tions are
generated as is the case with generator-type excit­ers. This means the resulting drawback of these
devices, namely the tendency towards sharpness
and with it listener fatigue, has been eliminated
from the Stereo Vitalizer Jack.
The Stereo Vitalizer Jack is equipped with un-
balanced jack connectors.

The SPL Vitalizer in practice

Voluminous b ass sounds you can feel not only
make the DJ’s life bet ter – the Stereo Vitalizer Jack
also allows dance/techno sound amplifi cation to
produce enormous volume without compromising
the fi nal audio quality. In mixing you can clearly
position different bass sounds with ease. E xces­sively hard or sharp sounds in the mid-range are
easy to manage. Intelligibility and accurate detail
are signifi cantly increased and the improved pres­ence brings voices to the fore. The brilliant, silky
highs round out the overall sound perfectly.

Applications

• Recording: Console EQ enhancing, subgroup insert

• Mixing: Fine polishing the fi nal mix

• Mastering: Remaking or preparing (especially
archival recordings)

• Digital signal processing: Lifelike analog sound
with less “digital edge”

• Sound reinforcement: Clearly greater volume
perception, allowing less of a load on the fi nal
stage and signifi cantly greater sound volume at
the same volume level

• Copying tapes: Perfect compensation of hi- and
bass-losses

“All rig ht Jack ! The Vital izer
Jack really works – indeed,
its effect on the bass end
of a track is indescribable.
I ran dancy drum box and
synth mixes through it and
got a kick to the lower fre­quencies that was impo s­sible to achieve w ith EQ
alone. Even some basic
acoustic guitar and voice
demos were lifted with a
pleasing soft bass effect.
‘Detail’ and ‘clarity’ are
much over-used words in
mixing circles, but th e Vital­izer Jack really does provide
them in spades.”

Brian Knave,
Electronic Musician (US)

“For the money, I don’t
know of a bette r spectrum ­enhancing, home-mastering
processor on the market.
The Stereo Vitalizer Jack not
only sounds great, it’s also a
cinch to operate.”
