Whilst the input EQ and output EQ screens only differ in minor ways – no
crossover filters on the input screen, and one less parametric band – this
screenshot does highlight a couple more points worthy of note for both.
1: Filter number 5 has been set to an elliptical low pass response. This type of
filter has no adjustment for ‘Q’ or gain (being a band pass filter) so these
parameters are removed from the table.
2: Filter number 6 has been selected as a notch filter, and so has a fixed (very
high negative) gain, but still has variable ‘Q’ (which may be increased greatly
above the default value chosen for a much narrower response).
