Parametric Filter Types and Their Uses
A wide selection of filter types has been made available under the PEQ section when editing input or output
filters. Scrolling through the various filter types is achieved by repeated presses of the ENTER key. Note that
this will only change filter types if the filter is BYPASSED or the GAIN set to 0dB. Bypassing the filter, then
changing types using the ENTER key will automatically set the gain back to 0dB.
Each filter type will be explained in turn in the following section.
Standard Parametric EQ
InA Input A PEQ:1<>
1k00Hz Q=3.0 0.0dB
The standard parametric band has adjustable
frequency, 'Q' (or Bandwidth) and Gain controls.
These affect a range of frequencies symmetrically
about the centre freqency as shown in the graph.
Various levels of cut and boost are shown to the left,
along with various 'Q' settings (gain boosts only are
shown below). Remember that 'Q' is 1/Bandwidth,
so the higher the 'Q', the lower the Bandwidth, and
the smaller the range of frequencies affected.
