So be aware the large fixed bass boosts may have a different effect than you expect
because of the way that they interact with the multiband compressor.
Low Frequency Parametric Equalizer is a specially designed parametric equalizer
whose boost and cut curves closely emulate those of a classic Orban analog para-
metric equalizer with conventional bell-shaped curves (within
±
0.15 dB worst-case).
This provides warm, smooth, “analog-sounding” equalization.
LF FREQ determines the center frequency of the equalization, in Hertz.
Range is 20-500Hz.
LF GAIN determines the amount of peak boost or cut (in dB) over a
±
10
dB range.
LF WIDTH determines the bandwidth of the equalization, in octaves. The
range is 0.8-4.0 octaves. If you are unfamiliar with using a parametric
equalizer, 1.5 octaves is a good starting point. These curves are relatively
broad because they are designed to provide overall tonal coloration, ra-
ther than to notch out small areas of the spectrum.
