The Vitalizer MK2-T is an equaliser concept which makes use of scientific psychoacoustic technology to process audio signals. The Vitalizer-technology has been constantly improved over the past nine years since its invention by SPL's Wolfgang Neumann and Hermann Gier. The Vitalizer MK2-T plug-in is modeled after Hermann's (SPL CEO), original privately owned hardware unit.

The hardware unit is described below:

"The Stereo Vitalizer MK2-T is the tube version of the successful Stereo Vitalizer MK2. The 'MK2-T' utilises two Sovtek 12AX7-double triode tubes. One of them is used within the Mid-Hi Tune filter and gives the mid frequencies even more accurate transparency with a soft, unobtrusive sound. The second tube is used within the Stereo Expander.The stereo image not only gains more width but also more depth, transparency and clarity because of the pleasant tube harmonics. Great emphasis has been put into maintaining mono-compatibility. The treble range is reworked with new LC-filters, which focus on achieving a smooth, silky sound pattern. High frequencies are livened up extremely noiseless without them sounding hard or aggressive."

"As with all Vitalizer models you can choose between a dry, percussive bass (Tight) or a punchy, soft and very deep sound character (Soft). The bass is accentuated without any risk of emphasising the lower mid frequencies unnaturally. An easy to use compressor complements the bass section allowing the correction of level change due to bass processing."

"The Stereo Vitalizer MK2-T is especially designed to serve the needs in recording, mastering, cutting and post production work. Used on complete mixes or being inserted into the subgroups to treat specific parts of the mix, the Stereo Vitalizer MK2-T will perform the same task as those esoteric and costly equalisers often used for audio sweetening but with far greater tonal flexibility and at a much lower cost."
