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 foundation. 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 Vitalizer is based on findings of psychoacoustics and audiometry. Its filter network is one of the few patented filters. It makes the richness of detail of audio signals more audible. Interventions in the sound image are more of a musical nature. Music productions sound more natural, lively, differentiated, easier to understand, more deeply layered and more widely spread apart.
