4.6.2 Notch Filters (full-range only)
Each full-range loudspeaker is equipped with eight notch filters, allowing
you to quickly remove feedback. Each notch filter has a Q of 24.
To access these notch filters, tap or click the Notch button on the parametric EQ.
Notch filters On/Off. By default, all notch filters are disabled. To enable notch filters,
click or tap on this button.
Power User Tip: You cannot make changes to a notch filter unless it is enabled.
Reset. To reset every notch filter to 0 dB, simply click or tap the Reset button. This
returns each filter to 0 dB, so that no frequency band is attenuated, and returns all
frequency parameters to their default state.
You can adjust any notch filter by tapping or clicking on any of the bands in
the graph and using your finger or mouse to set the amount of attenuation.
When any band is selected, the two controls at the top of the parametric
EQ will switch to control that band’s frequency and attenuation. These
controls allow you to make fine adjustments to each band.
You can turn off an individual filter by pressing the On/Off button next to the Gain
control or by tapping in the graph.
