Tube Vitalizer is based on sound processing concepts that take advantage of the findings of audiometry and scientific psychoacoustics. Audio productions thus sound livelier, more transparent and have more detail. It also increases perceived loudness. Interventions in the signal sound musical and natural, more deeply layered and more broadly distributed.
- Maximum input level: 24dBu
- Input impedance: 22kΩ
- Output impedance: 600Ω
- Common mode rejection (1kHz): 70dB
- Frequency response (-3dB, tube section off): 10 Hz – 100 kHz
- Frequency response (-3dB, tube section on): 30 Hz – 100 kHz
- THD + N (0dBu, 10 Hz – 22 kHz): 0.002%.
- Noise (A-weighted): -89dB
- Dynamic range: 113dB
Program Equalizer
On the left side of the front panel are the parameters of the patented Vitalizer core circuit. Here, the “Drive” controls the filter network. Via the “Bass” control, the perceived timbre of the bass range can be adjusted from soft to hard. Further a One-Knob compressor is inserted with a LED for the indication of the Gain Reduction. The “Mi-Hi” control sets the application frequency at which frequencies above are boosted and frequencies below are cut. “Process Level” adjusts the intensity of “Hi-Mid” and “Bass”. In addition, there is a high and high frequency stage with coil filter (LC) and a corresponding potentiometer for the intensity.
The tube stage, which can be switched on the right side, consists of three tubes: First, the signal of each channel passes through one tube and. Then the signal is merged and passes through a third tube. Finally, the signal can be limited in level by a shunt limiter and get a tape machine-like saturation sound.
The stereo inputs and outputs of the Vitalizer are each equipped with two Neutrik XLR connectors. The signal transmission is electronically balanced with a nominal level of +6 dB.
The key feature of Vitalizer technology is the unmasking of superimposed sound components. In this process, louder frequencies are minimally offset in time to make quieter signal components audible.
Since the human ear roughly corresponds to “equal loudness curves” and is not linear, the Vitalizer adapts the frequency spectrum to our hearing perception and thus improves the perceived loudness.
