III. Parametric Equalizer
The EQ section of the Model 2032 Microphone Preamplifier / Parametric Equalizer
offers precision and adaptability when sculpting the response of any source. Its
operational characteristics, duplicated from the Model 8200 Parametric Equalizer, have
been honed through many years of use in the most critical recording and mixing
situations and have proven both reliable and remarkably accommodating.

The basis of the parametric design topology, in general, specifies control over not only
gain or attenuation, but also over both frequency and “Q” factor in multiple user-defined
bands. In the case of parametric equalization, “Q” is defined as the center frequency of
the alteration (whether gain or attenuation) divided by the bandwidth of that alteration. It
follows, then, that low values of “Q” affect a wide range of frequencies around the cut or
boost, while high values of “Q” specify a narrow slope around the center frequency.

Another important aspect of true parametric equalization, as embodied in the Model
2032 equalizer section, is the existence of overlapping frequency bands, which provide
great precision and flexibility.

great precision and flexibility.
Specifically, this parametric equalizer provides complete control over a wide frequency
range and “Q” setting, along with 15 dB of cut or boost on four individual bands, with the
front panel controls for frequency and “Q” mounted concentrically. The addition of the
“Q” characteristic empowers the user to maintain precise and musical control over the
tonal attributes of the spectrally processed signal.

“Q” characteristic empowers the user to maintain precise and musical control over the
tonal attributes of the spectrally processed signal.
The availability of up to 15 dB of gain or attenuation is significant, affording the user
unprecedented control from minute adjustments to dramatic alterations over completely
flexible overlapping multiple bands. Thus, it is possible to achieve almost any particular
“sound” that is desired, no matter if the goal is a subtle modification or an audible
coloration effect.

Front panel controls for the Model 2032 equalizer section include an illuminated in/out
pushbutton switch plus four color-coded bands with amplitude and dual-concentric
frequency and "Q" potentiometers. The amplitude pots are continuously variable
between +15 dB and -15 dB, with highly accurate 0 dB settings. Each band offers a
wide array of frequencies to select on the outer knob of the dual-concentric
potentiometer, with a good deal of overlap between bands to accommodate almost any
combination of cuts and boosts. The Low and High bands offer counter-clockwise
detents for shelving curves in addition to the variable "Q" values from 0.4 to 4 found in
the other two bands--all on the central knobs of the dual-concentric potentiometers.
Frequency markings can be found along the inner, larger ring of numbers, while the
outer, smaller numbers encircling the dual-concentric potentiometer denotes "Q" value.
