Improved high and harmonic
frequencies result in a silky
top-end with better
separation and intelligibility.
Sets the amount of LC-EQ
being added to the signal.
In other words, increasing the Process value also increases the
intensity of the Mid-Hi Tune filter and the Bass SOUND filter, whilst
dominant mid frequencies are damped by amplitude-correlated
phase shiftings. This improves the perception of loudness, clarity
and the bass punch, i.e. the strength and fullness of the audio
signal.
The Stereo Vitalizer MK2-T is equipped with LC filters which have
been used in filter designs from the 60s and 70s. The filter-
network processes the high end with a passive coil/condenser
filter.
Coils are known for their pleasant ‘retro’ sound. When getting
saturated they produce a special harmonical structure giving a
certain punchy sound that we know from old filter designs. The
sound gets more mid-range and presence. At the same time a
certain amount of roughness is introduced. This is especially
beneficial to vocals and helps them to stand out in the mix
without altering level.
By influencing the phase relationship in an intelligent fashion,
the filtering emphasises the perception of high and harmonical
frequencies.The effect significantly improves the speech intelligi-
bility and the transparency. Old archived recordings sound fresh
and silky again.The brilliance of any audio signal can be improved
without it sounding sharp.
The control range is 2 kHz to 20 kHz.
The Intensity control sets the amount of LC-EQ being added to
the signal.
You can then listen to the LC-EQ control separately, when you
close the Process control (extreme left). The Bass Sound and Mid-
Hi Tune controls do not function any more.
