The Frequency Graph display in the 1-Band EQ shows a control dot that indicates the center frequency (Peak, Shelf and Notch Filters) or the cutoff frequency (High Pass and Low Pass filters) for the currently selected filter type.

The 1-Band EQ may be set to any one of six EQ types: High Pass, Notch, High Shelf, Low Shelf, Peak, and Low Pass, by clicking the corresponding icon in the EQ Type selector.
