MID Frequency determines the center frequency of the equalization, in
Hertz. Range is 250-6000Hz.
MID Gain determines the amount of peak boost or cut (in dB) over a
±
10
dB range.
MID 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 octave is a good starting point.
With Five-Band presets, the audible effect of the midrange equalizer is closely asso-
ciated with the amount of gain reduction in the midrange bands. With small
amounts of gain reduction, it boosts power in the presence region. This can increase
the loudness of such material substantially. As you increase the gain reduction in the
midrange bands (by turning the

control will have progressively less audible effect. The compressor for the
midrange bands will tend to reduce the effect of the
M
ID
frequency boost (in an at-
tempt to keep the gain constant) to prevent excessive stridency in program material
that already has a great deal of presence power. Therefore, with large amounts of
gain reduction, the density of presence region energy will be increased more than
will the level of energy in that region. Because the 3.7 kHz band compressor is par-
