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.
