Process
Both BASS and MID-HI TUNE work with two differ-
ent signal paths: the original signal and the processed
signal, both of which are mixed together at the output.
The PROCESS control determines the amount of pro-
cessed signal used, i.e. the intensity of the effect gener-
ated by the BASS and MID-HI TUNE filters. Furthermore,
the PROCESS control also determines the damping inten-
sity of dominant mid frequencies (see the previous sec-
tion). Dominant mid frequencies are reduced with higher PROCESS
settings. All frequencies below the cut-off frequency selected with
the MID-HI TUNE control are affected.
LC-EQ
The high frequency filter is a broad band filter too and
can actually affect mid frequencies to add presence and
sharpness, specially to vocals. The frequencies affected
range from 2 kHz (hard left) to 20 kHz (hard right). The
INTENSITY control determines the intensity of the LC-EQ
(see the next section). The LC-EQ gets its name from the
hardware version’s high frequency filter, which is based
on a passive coil filter. Coil filters are inductive filters
and the symbol for inductance is “L”. The abbreviation for coil filter
is “LC” (where C stands for capacitor). This type of filters are well
known for their pleasant, soft sound. Coil filters were standard com-
ponents up to the 1960’s, when they were quickly replaced with the
advent of cheaper resistor-capacitor (RC) filters. The sound of clas-
sic “vintage” gear has a lot to do with the use of these components.
When programming the Vitalizer plug-in we payed special attention
to faithfully emulating the sound character of the original LC-EQ. The
LC-EQ can improve the brilliance of individual or sum signals without
making them sound too sharp. No signal artifacts are created in the
process, as opposed to other high frequency enhancement systems,
like the so-called exciters, in order to avoid ear fatigue. The Vitalizer
simply improves the sound structure of the original signal.
