3.2D Equalization
Equalization (EQ for short) boosts or cuts response at specified frequencies to
alter a sound's tonal characteristics. With a lozvpass response, signals below
a specific cutoff frequency are either boosted or cut. With a highpass
response, signals above a specific cutoff frequency are either boosted or cut
A bandpass response boosts or cuts at a specific resonant frequency. The
bandwidth setting determines the range of frequencies that are boosted or
cut.
The Ultraverb H's EQ is a two stage type with each filter section connected in
series. Thus, one stage could boost the bass, while the other stage provides a
bandpass response at a higher frequency.
Each of the following parameters is preceded by a 1 or 2, indicating whether
the parameter is part of the 1st or 2nd stage. XX indicates a two-digit
number, YY two letters.
YY Filter Type Lo,bP,Hi
Chooses the tvpe of filter response: lowpass (Lo), highpass (Hi), or bandpass
(bP).
F.XX Filter Frequency .060-6.4 kHz
Sets the cutoff frequency for Lo or Hi modes, and the resonant frequency for
the bP mode.
b, cXX Amount of boost or cut 0-24 dB
Determines the degree to which the selected frequencies will be either
boosted or cut.
o Bandwidth .09-2.5 octaves
Varies the range of frequencies to be boosted or cut. Smaller numbers give a
sharper, more resonant response.
3.2E Exciter
The Exciter effect enhances a sound through a unique combination of phase
shift and amplitude changes at various frequencies. Rather than spend the
next three pages trying to describe what it does, just play with it and listen—
you’ll like it.
F Frequency 00-15
Determines the frequency at which excitement takes place. A setting of 0
will turn off the exciter, but setting the Contour parameter to 0 is preferable.
