The 9530 Tube Vitalizer for mastering from SPL is a multi-capable audio processing unit that, with its combination of tube, coil and transistor circuitry, can be used for mixing, mastering and restoration of sound. The Vitalizer offers more than simply equalization. It includes additional processing circuitry to maximize efficiency, and is designed to be simple to use as well, both in single-channel and subgroup processing. It is also a capable unit used in refining summing signals.

The Tube Vitalizer is designed for discerning applications in professional recording, mastering and cutting. All effect intensities and potentiometer values and characteristics are optimized for the refined requirements mastering. The sound processing of the Tube Vitalizer is split into two sections: On the left hand you find the controls of the Vitalizer-circuitry and the compressors. The right side features the tube section, which can be used independently of the Vitalizer-section as a high quality, low-noise tube-line preamp whenever you just want to give your programme material the warmth and smooth bottom-end of tubes.
