TUBE VITALIZER
SPL´s Tube Vitalizer is the top-of-the-line product of the Vitalizer
range. It is designed for the sound enthusiast in professional
recording, mastering and cutting. The effect intensities are opti-
mized for this delicate sound processing.
The Tube Vitalizer combines the finest audio technologies: Tube
technology, RC & LC-technology, transistor- and semiconductor-
technology. The unique combination of dynamic equalizers,
amplitude-controlled phase correction, harmonic filtering opens
up a whole new listening dimension by adapting the sound
pattern to the non-linearities of the human ear.
The Tube Vitalizer gives the mid frequencies accurate transpa-
rency with a soft, unobtrusive sound.The treble range is reworked
with broadband shelving filters, which focus on achieving a
smooth, silky sound pattern. Filtering can be altered by adding a
passive LC-filter network. High frequencies are livened up without
them sounding hard or aggressive.
The Tube Vitalizer uses an hitherto undocumented filter
network to process the low frequency range. The bass is accentu-
ated without any risk of emphasizing the lower mid frequencies
unnaturally. You can choose between a dry, percussive bass
(Tight) or a punchy, soft and very deep sound character (Soft).
Both sounds can be altered by adding a passive LC-filter network.
The bass and high frequency section are both equipped with
easy to use compressors based around the THAT 4301.
The output section can be switched from solid-state to tube
operation. Now you can add that warm and smooth tube sound
to your mix and directly compare it with the “non-tube” mix. The
tube stage is an original AEG design from 1955. It utilizes three
tubes. This stage reduces crosstalk to 54 dB which is typical for
vinyl-cutting. Responding to latest psychoacoustic research it is
believed that vinyl sounds “better” than CD because of a more
natural sound stage. There are no sounds in nature that are cohe-
rent but have a channel separation of about 90 dB like on CD. This
tube stage gives you the possibility to add vinyl-sound to your CD
production.
The Tube Vitalizer will perform the task of audio sweetening
with great tonal flexibility and musicality. The result of processing
is a pleasanter and livelier sound pattern with an unrivalled
wealth of detail.
