SPL Tube Vitalizer

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.
