SPL Tube Vitalizer Mastering Processor

The SPL Tube Vitalizer, is a powerful valve-based harmonics processor for mixing, mastering and restoration applications.
The SPL Tube Vitalizer takes SPL’s popular technology and repackages it in a sophisticated more suited to mastering applications with the different processors accessible independently.  In addition to the Vitalizer section, it boasts both a solid-state and valve stage which can be selected at the push of a button.
The SPL Tube Vitalizer uses Psycho acoustic theory to achieve a well-balanced tonality, depth and clarity difficult to achieve with EQ.
