As a general guide, EQ band 0 should be used for low frequencies, EQ bands 1 through
8 should be used for mids, and EQ band 9 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, centre frequency, and Q) for
each of the five EQ bands.

Left Lowers the highlighted parameter.

Power Exits the graphic EQ screen.
Pre-cut. If too much positive gain is added through the graphical EQ, your music may
distort. The
Precut
setting allows you to apply a global negative gain to decoded
audio, cancelling out positive gain from the EQ. This will prevent distortion when
boosting certain frequency ranges, at the expense of making audio quieter.
Alternatively, precut can be used with a flat EQ curve to implement a volume cap.
For example, on a player that allows overdriving the headphone output to +6dB,
maximum volume can be capped to +0dB by applying 6dB of precut. Note that
precut is not applied if EQ is disabled.
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.
