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.
Vitalizing
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 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 Stereo Vitalizer Mk2-T features a high frequency and harmonics stage with coil filters (LC) and a stereo expander to broaden the stereo image.
The De-Masking
A key feature of the Vitalizer is the unmasking of superimposed sound components. The Vitalizer thereby relates the time of perception of a frequency to its amplitude. Through a minimal temporal offset of loud frequencies, quieter, previously superimposed sound components are “de-masked” and thus become audible.
The Adaptation to Curves of Equal Loudness
The non-linear sensitivity of the human hearing is described already in the 1930s by the “Fletcher-Munson curves”.
These “curves of equal loudness” (today defined by the standard ISO 226:2003) illustrate the equal perception of loudness as a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones.
The Vitalizer adapts the frequency spectrum to the curves of equal loudness, which improves the loudness perception in particular.
Inputs & Outputs
The two channels of the Stereo Vitalizer Mk2-T are equipped with Neutrik XLR sockets and jack sockets connected in parallel. The signal transmission is electronically balanced with a nominal level of +6 dB.
For audio professionals and enthusiasts seeking to elevate their sound processing with precision and clarity, the SPL Audio Stereo Vitalizer Mk2-T offers a sophisticated solution designed to enhance audio signals in the most transparent and effective manner. Whether you are mixing, mastering, or performing live audio adjustments, the Vitalizer Mk2-T provides a powerful tool to enrich your soundstage, increase presence, and improve overall audio quality without introducing unwanted coloration or distortion.
Traditional audio enhancement tools often struggle to maintain the natural integrity of a signal while attempting to add clarity and depth. The SPL Stereo Vitalizer Mk2-T addresses this challenge by using advanced analog circuitry that revitalizes audio sources with minimal noise and distortion. This means that the nuances of your recordings or live audio remain intact, delivering a vibrant yet authentic listening experience. The device’s ability to work seamlessly with various audio setups makes it a versatile asset in any professional studio or live sound environment.
At the core of the Vitalizer Mk2-T’s performance are its meticulously engineered analog inputs and outputs. With a maximum input gain of 22 dBu and an input impedance of 22 kΩ, the unit ensures compatibility with a wide range of audio sources and instruments, maintaining signal integrity and preventing loss of detail. The output impedance of 600 Ω guarantees strong and clean signal transmission to downstream equipment, minimizing interference and preserving audio fidelity. A high common mode rejection ratio of 85 dB at 1 kHz reduces hum and noise from electrical interference, ensuring a cleaner sound.
The device operates across an impressive frequency range from 10 Hz to 100 kHz (-3 dB), which goes well beyond the audible spectrum. This extended bandwidth means the Vitalizer Mk2-T processes audio signals with exceptional precision, preserving the harmonic content that contributes to a natural and full-bodied sound. Its total harmonic distortion plus noise (THD + N) rating of just 0.0019% between 10 Hz and 22 kHz translates into ultra-clean signal processing, so your audio remains pristine and uncolored. The extraordinarily low noise floor at -99 dBu (A-weighted) and a dynamic range of 121 dB allow for a wide range of signal intensities to be handled without compromise, facilitating both subtle enhancements and dramatic improvements.
Powering the Vitalizer Mk2-T is an internal linear power supply equipped with a toroidal transformer, delivering stable and clean operating voltages (+/- 15 V for analog audio and +12 V for relays and LEDs). Unlike switching power supplies, this design minimizes electromagnetic interference and contributes to the overall sonic purity of the device. The unit supports selectable mains voltages of 230 V AC at 50 Hz or 115 V AC at 60 Hz, making it suitable for use in diverse geographical locations. With a maximum power consumption of just 20 watts, the Vitalizer Mk2-T is energy efficient and reliable for extended studio or live use.
In practical terms, the SPL Stereo Vitalizer Mk2-T is ideal for mastering engineers, mixing professionals, and live sound technicians who need a transparent enhancer to bring out the best in their audio sources. Its robust build quality and precise circuitry make it a dependable component in any professional setup. Whether you want to add presence to a vocal track, increase the clarity of a bass line, or simply breathe life into a dull recording, this device offers a straightforward yet powerful approach to audio enhancement.
Investing in the SPL Audio Stereo Vitalizer Mk2-T means choosing a trusted, high-performance analog processor that delivers measurable improvements in sound quality. Backed by SPL’s commitment to audio excellence, it empowers users to achieve professional-grade results with confidence. For those who demand transparency, precision, and reliability in their audio enhancement tools, the Vitalizer Mk2-T stands as a definitive choice to elevate your sound to the next level.
