SPL Audio Vitalizer Mk3-T

The patented Vitalizer circuitry makes the Vitalizer Mk3-T an unsurpassed sound designer. Whether live or in the studio, audio productions sound more alive, have more details, more transparency, a higher perceived loudness and, if required, an overwhelming bass fundament.

The Vitalizer Mk3-T not only swaps the classic, golden robe of the previous model for the new, black design of the SPL Studio Series – the higher internal audio voltage of +/-18 V elevates this third generation SPL classic to greater sonic results and impresses with an even better and more detailed sound experience.

• The De-Masking
A key feature of the Vitalizer technology is the unmasking of superimposed sound components. The Vitalizer thereby relates the time of perception of a frequency to its amplitude. Through a minimal temporal offset of loud frequencies, quieter, previously superimposed sound components are “de-masked” and thus become audible.

• The Vitalizer adapts the frequency spectrum to the curves of equal loudness, which improves the loudness perception in particular.
The non-linear sensitivity of the human hearing is described already in the 1930s by the “Fletcher-Munson curves”. These “curves of equal loudness” (today defined by the standard ISO 226:2003) illustrate the equal perception of loudness as a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones.
