Remember – to change filter types, press BYPASS
to bypass the filter, and then use ENTER to select the
filter type.
The low and high pass variable 'Q' filters have
adjustable frequency and 'Q' (or Bandwidth) controls.
The 'Q' control adjust the damping of the filter, so that
low 'Q' settings show less overshoot at the turnover
frequency, but also slower roll-off.
Remember that 'Q' is 1/Bandwidth, so the higher
the 'Q', the lower the Bandwidth, and the smaller the
range of frequencies affected. The filter is primarily
12dB/Octave, but in achieving this sort of roll-off with
a high 'Q' value will result in quite a large overshoot in
level at the turnover frequency. This type of filter is
often also called a resonant filter.
