OPTIMIZER
The frequency control (Hz) will set the center-frequency
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
