The High Frequency has a Shelving button instead of a Peak button. Since the Constant Energy Curve is so broad in the lower frequencies, there is no need for a low frequency shelf button.
With 4 bands of controls, each of the lower 2 have slightly different frequencies, allowing the lower band to go to 16 Hz, and the upper 2 bands are identical. The IN button is a silent IN/OUT button that does not bypass the unit, but it bypasses the filters.
