Parametric Equalizers
FREQUENCY control
This selects the specific center
frequency to be affected. This
control works along with the
select switch below it to provide
full audio spectrum frequency
range for each band.
FREQUENCY select switch
This ingenious little three-posi-
tion switch allows you to select
one of three frequency ranges,
allowing the
FREQUENCY control
to cover the entire audio spec-
trum with greater resolution. The
“
x0.1” setting allows frequencies
of 10 Hz to 200 Hz to be dialed
in. The “
x1.0” setting provides the
100 Hz to 2 kHz frequencies
silkscreened on the front panel.
The “
x10” setting provides the
frequencies of 1000 Hz (1 kHz) to
20 kHz.
BYPASS switch
This switch allows parametric
equalizers to be bypassed for easy
comparison between equalized
and non-equalized signal.
BAND 2
The controls of this second
parametric are the same as those
found in BAND 1. Two bands
allow for two separate frequencies
to be modified. The two paramet-
ric bands are connected in series,
so simply setting the filters to the
same frequency can double the
amount of boost or cut. Total cut
for a single frequency can
amount to -30 dB!
LEVEL control
This allows between
+12 dB of
boost and -15 dB of cut at the
center frequency.
BW control
BW stands for “bandwidth”. This
allows selection of a skirt as
narrow as
.03 octave (feedback
control) or as wide as 2.0 octaves
(broad tonal shaping) around the
center frequency.
