when working in Parametric, Band-pass and Notch mode where-as in Low-pass mode it will determine the upper, and in High-pass the lower corner frequency.

Below is a chart for pinpointing the exact frequencies. The scale has 11 marks. The center position (12 o´clock) is number 6:

	Band 1	Band 2	Band 3	Band 4
1	10,789	15,778	32,436	110,74
2	19,819	24,895	79,621	195,90
