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.
