The Filter 1 and Filter 2 tabs provide the same set of controls for each filter.
Both Filter 1 and Filter 2 can be set independently. Select from the following Filter Type options:
The Frequency control lets you set the center frequency for the selected Filter Type (from 20 Hz to 21.0 kHz).
When the Filter Type is set to Low Pass or High Pass, the Slope control is available. The Slope control lets you set the slope for the filter from the selected Frequency to –INF (12 dB/O or 24 dB/O).
When the Filter Type is set to Band Pass or Notch, the Q control is available. The Q control changes the width of the filter around the center frequency band. Higher Q values represent narrower bandwidths. Lower Q values represent wider bandwidths.
