stereo systems does. The high shelf filter is adjusted the same way as the low
shelf filter, except that it works on the high end of the frequency spectrum rather
than the low end.
As a general guide, EQ band 0 should be used for low frequencies, EQ bands 1 through
3 should be used for mids, and EQ band 4 should be used for highs.
Enable EQ: This option controls whether the EQ is on or off.
Graphical EQ: This option brings up a graphic EQ screen, which allows adjustment of
each of the three parameters described above (gain, center frequency, and Q) for
each of the five EQ bands.
Key Action
Up Raises the highlighted parameter.
Down Lowers the highlighted parameter.
Left Moves to the previous EQ band.
Right Moves to the next EQ band.
Navi Toggles the cursor among the three pa-
rameters (gain, center frequency, Q) for
the selected EQ band.
A-B Exits the graphic EQ screen.
Pre-cut: If too much gain is added through the graphical EQ, your music may distort.
The PRECUT setting allows you to adjust the overall gain of the EQ.
If your music distorts when using the EQ, trying changing this setting to a nega-
tive value.
Simple EQ: This option provides an easier alternative for those who are daunted by all
of the parameters that can be adjusted using the graphical EQ. With the SIMPLE
EQ, the only parameter that can be adjusted is the gain.
Advanced EQ: This sub menu provides options for adjusting the same parameters
as the GRAPHICAL EQ. The only difference is that the parameters are adjusted
through textual menus rather than through a graphic interface.
Save EQ Preset: This option saves the current EQ configuration in a .cfg file.
Browse EQ Presets: This menu displays a list of EQ presets, as well as any EQ con-
figurations saved using the SAVE EQ PRESET option. Users unfamiliar with the
operation of a parametric EQ may wish to use the presets instead of trying to
configure the EQ, or use the presets for designing their own custom EQ settings.
