Appendix III: Parametric Filter Types and Their Uses
A wide selection of filter types has been made available under the PEQ sectiosn
when editing input or output filters. Each filter type will be explained in turn in
the following section.
Standard Parametric EQ
The standard parametric band has adjustable frequency, ‘Q’ (or Bandwidth) and
Gain controls. These affect a range of frequencies symmetrically about the centre
frequency as shown in the
graph.
Various levels of cut/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.
