Understanding the {{T1}} Para EQ
Understanding the {{T1}} Para EQ


[[Image:T1ParaEQWidth-02.png|Thumb|Width = 0.2 Octave (0.2 Octave (0.10 Octave on either side of the Freq)]]


Starting with the {{T1}} looking like this


[[Image:T1ParaEQWidth-05.png|Thumb|Width = 0.5 Octave (0.5 Octave (0.25 Octave on either side of the Freq)]]
[[Image:T1ParaEQSettings.png]]


imagine that we are increasing the Width parameter.
In the plots below the centre point (lowest representing -6dB ) is the Frequency that you select with the middle button, in this case 165 Hz (E3, not shown in the Simulator). The tick marks on the X-axis are roughly 1 octave. I have deliberately omitted actual frequencies because I wanted to give you a sense of relative differences rather than suggest that this is what is actually happening.

The plots below suggest the widening range of notes that will be affected by the Level (-6 dB) as we go increase the Width. The plots point down because we are applying a *negative* level. The depth of the plot (distance down) would vary up and down as we changed the Level.


The following are extremely rough approximations. For anyone reading - there is nothing scientific about these plots. The appearance suggests a level of precision that is way beyond what I did to create these images. (Normal distribution curve, manipulated the standard deviation). Just go for the rough visual impression. Thanks!
