On/Off (Effect On/Off)
Switches the 3-band parametric EQ effect on and off.
* The following parameters affect the Lo, Mid, and High EQ
together.
Q
The range is narrowed as the value is increased.
This adjusts the equalizer bandwidth (the range of
frequencies to which the equalizer is applied). The
bandwidth is narrowed as the value is increased, resulting in
a more precise (notched) equalization. Use higher Q
settings to affect specific frequencies and give the tone
particular qualities. Conversely, the bandwidth becomes
broader as the value is lowered. Use lower Q settings when
you want to adjust the overall low end or high end and
change the overall tone.
Freq (Frequency)
Adjusts the EDs center frequency (for the range affected).
The frequency (upper range) increases as the value is raised.
Gain
Adjusts the volume level for the equalizer adjusted with the
Q and FREQ settings above. The volume level for the
frequency range is boosted more as the knob is turned
further to the right of center; turning the knob to the left of
the center position cuts those frequencies.
Level
Adjusts the overall volume level of the 3-band equalizer. The
volume level is boosted more as the knob is turned further to
the right of center; turning the knob to the left of the center
position cuts those frequencies.

frequency response of a filter.
