Resonance

This control is used to emphasize the amplitude of the frequencies at, and close to, the cutoff frequency. If you are using a low pass filter, increasing resonance will emphasize frequencies around the set Filter Frequency and de-emphasize the rest of the frequency spectrum, making the sound thinner. Further raising the RESONANCE knob will make the sound resonant to a point where the filter adds a ringing quality to the sound. Exactly where in the frequency spectrum this “ringing” appears, depends on the Filter Frequency setting.

The figure shows a 24dB lowpass filter with different resonance amounts (Q-values).

Q = 0.5 represents zero Resonance amount and Q = 4 maximum amount.

If you have the high-pass or LP+Notch filter selected, increasing Resonance will work pretty much as with the LP filter.

When you use the band-pass filter, adjusting the Resonance also adjusts the width of the pass-band.

When you raise the Resonance, the band where frequencies are let through, will become narrower.

Q=0.5 represents zero Resonance amount and Q=4 maximum amount.

Если вы, например, выбирете фильтр низких частот и повернёте ручку Frequency по часовой стрелке, все больше и больше высокочастотного материала будет проходить через фильтр.

Чем больше вы «открываете» фильтр НЧ, тем более высокочастотный сигнал будет на выходе

Обратите внимание, что если Envelope Amount установлено в максимальное левое положение, поворот ручки Frequency не изменит звук, как ожидалось. Для дополнительной информации, см. ниже.
