Turn the boost/cut control to +18 dB (full clockwise rotation) . This will show the present center frequen- cy and “Q” settings on the analyzer.
Rotate frequency control to the frequency you wish to a d j u s t .
Adjust “Q” setting to match the width of the dip or peak you are addressing .
Finally, adjust the gain control to achieve the desired response curve .
