OPERATION
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,
rather than to notch out small areas of the spectrum.
The LF parametric can be used in the mid-bass region (100-300Hz) to add "warmth"
and "mellowness" to the sound when boosting. When cutting, it can remove a
"woody" or "boxy" sound. In our presets, we tend to use it very sparingly (in the
order of 1 dB boost) to add a bit of extra bass warmth.
One formula for producing a very "big" bass sound on the air is to use a peaking
