OPERATION OPERATION Cont. Shown below is the typical symmetrical response curve of a swept parametric The two shelving filters are designed to roll off the frequency response of the band filter with the Frequency control set at 1 kHz, the Level set at +15 and -15 Signal; the Low Shelf cuts the frequencies 3 dB at the control’s indicated setting dB, and the Octave control set at .3, .5, 1, and 3. These curves remain consistent and rolls off below, and the High Shelf cuts the frequencies 3 dB at t
