The patented Vitalizer circuitry makes the Mk2-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 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.

There are the five controls of the Vitalizer core circuit.

Drive controls the level going into the filter network.

The bass emphasizes a soft or hard tone  and the compressor catches level peaks.

Mid-Hi Tune sets the frequency of operation above which frequencies are boosted and below which frequencies are cut.

Process Level adjusts the intensity of Mid-Hi Tune and bass.

In addition to the Vitalizer core circuit, the Stereo Vitalizer Mk2-T features a high frequency and harmonics stage with coil filters (LC) and a stereo expander to broaden the stereo image.
