Control Elements For the human ear, the sound is more pleasant and easier to
perceive than the original. In other words, increasing the Process
value also increases the intensity of the Mid-Hi Tune filter and the
Bass filter, whilst dominant mid frequencies are damped by
amplitude-controlled phase shiftings. This improves the percep-
tion of loudness, clarity and the bass punch, i.e. the strength and
fullness of the audio signal.
The Stereo Vitalizer Jack works with coil filters and controlled
changes of the phase relationships of the high frequencies and
harmonics.
We consciously did without the generator principle of “Exciters”.
The Stereo Vitalizer Jack's Brilliance circuitry does not add any
distortions to the original signal, unlike with the generator prin-
ciple. It extracts all the information it needs from the original
signal. This significantly reduces the hearing fatigue effect on the
listener. By influencing the phase relationship in an intelligent
fashion, the filtering emphasizes the perception of high and
harmonical frequencies. The effect significantly improves the
speech intelligibility and the transparency. Old archived recor-
dings sound fresh and silky again. The brilliance of any audio
signal can be improved without it sounding sharp.
If you close the Process control (extreme left), the Bass and Mid-
Hi Tune controls do not function any more. You can then listen to
the Brilliance circuitry control separately.
The Mid-Hi Tune and the Brilliance circuitry complement each
other in an ideal fashion. While the Mid-Hi Tune sets the
frequency above which the programme material is lifted and
below which the damping takes place, the Brilliance circuitry
comes in place to extract certain frequencies from this process.
This is very helpful, when you are processing material with lead
vocals: Using the Mid-Hi Tune will generally damp some speech
frequencies and the voice moves into the mix loosing a bit of its
presence. Use the Brilliance circuitry to bring it back up front.
