The Tube Vitalizer presents the patented Vitalizer filter network in the most sophisticated and beautiful way.
Compared to traditional equalizer designs, the Tube Vitalizer offers virtuoso processings with maximum efficiency and ease uf use. In mixing, mastering and restauration the Tube Vitalizer fulfills the highest demands.
With the Tube Vitalizer you can chose between familiar RC filters (condensers) or the often very interesting, warmer sounding LC filters (coils) for filtering bass and high frequencies. The sonic differences are similar to those of tubes compared to semi-conductors – sometimes even more dramatic. LC filters can saturate in a similar way to tubes, producing a pleasant harmonic structure. LC filters activate a passive coil network which is integrated into the active filter path. Bass processing for example results in a subjectively more powerful sound with more sustain. LC filters not only affect the Bass section, but also the mid-damping behaviour of the Hi-Mid Tune so that low-mid frequencies in particular benefit from it. The sound often gets more punch and directness.
An LC filter can also be added to the high frequency filtering to improve presence in the mid-range, which is ideal for vocals. Especially in mastering applications the LC filters add another tonal dimension to your processing repertoire.
The second innovation in the Tube Vitalizer design is the inclusion of two compressors, one for the bass and one for the top-end filtering. These compressors allow to compensate for level changes due to the processing. Alternatively they can also be used for sound shaping of course.
The compressors operate with a soft-knee characteristic to provide unobtrusive results, while Attack, Release and Threshold are pre-set for their frequency range (bass or top-end processing). This results in highest ease of use and perfect level control even when intensive processing is applied.
