NON STANDARD EXAMPLES CONFIGURATION:
With the parametric equalization point, you also could simulate shelving and notch
filters.
In order to carry out a shelving filter, you should select the frequency 35 Hz for low
frequencies or 16 KHz for high frequencies and a very small Q of 0.4 for example. The
next picture shows different answers of the equalizer card simulating shelving filters for
low and high frequencies, at different gains and attenu5, +10, +15, -5, -10 & -15:
You could also make a filter type notch, selecting the high Q (15) that the equalizer
card allows. The next picture shows a filter type notch of 15 dB of attenuation at 1 KHz:
