Cutoff Frequency

In a filter, the cutoff frequency is the point where the response is 3 dB down in amplitude from the level of the passband. Beyond the cutoff frequency, the filter will attenuate all other frequencies, depending on the design of the filter. On a sweepable shelving EQ or filter, what you are “sweeping” (or changing) is the cutoff frequency. To our ears, this changes the point at which the filter is operating.
