Program Equalizer. Patented. Legendary.

A completely different type of EQ, with which almost virtuoso interventions in the sound image become possible. When mixing, mastering and restoring, the Tube Vitalizer goes beyond traditional equalization.

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.


These 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. The coil filter (LC) makes the bass more pithy 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 Tube Vitalizer has a high frequency and harmonics processing stage with

Frequency and Intensity controls and switchable coil filter (LC) as well as compressor.
The switchable tube stage is constructed with three tubes: first, left and right pass through their channel output tube, then the channels pass jointly through the third tube as a stereo signal.

As a little treat, the Tube Vitalizer offers a shunt limiter. This limits the level according to a characteristic curve tuned to the tubes and provides the signal with a sonic effect similar to the saturation effect of analog tape machines.
