HPF sub-menu [Standard Filters]– from the sub-menu page, using the PM2 encoder, it is possible
to set the HPF in Bypass or as one of the 8 Standard Filters: Buttw_1st, Buttw_2nd, LRiley_2nd,
Bessel_2nd, Buttw_3th, Buttw_4th, LRiley_4th, Bessel_4th.
The following is an example of a HPF sub-menu screen with the filter set at 400Hz as 24dB
Linkwitz/Riley on Output1... using the name “High” (see later for assigning a Name to the outputs):
The filter's Frequency can be set already within this editing page using the PM3 encoder, but here
is for Frequency “fine tuning” being the Frequency increment/decrement done by 1Hz steps.
For a quick Low Cut Frequency setting, need to press the ENTER Button for accessing the Low
Cut Frequency Fast Setting Page.
“Low Cut Frequency”: the selectable frequencies range is from 20Hz to 20kHz.
Here, the NAV/PM1” encoder will increment/decrement the Frequency value by step of one
thousand Hz, the PM2 by steps of one hundred Hz and the PM3 by steps of one Hz.
HPF sub-menu [Custom Filters]– from the sub-menu page, using the PM2 encoder, it is also
possible to set the HPF as “Custom Filter”, where this means that the HPF is builded as cascade
of IInd Order Cells, which number is depending from the filter's order and where for each Cell can
be set independently the Low Cut frequency and the Q.
More precisely, the available independent parameters for setting are the following:
1.
Customm_2nd: builded using 1 IInd order Cell, where Low Cut Frequency and Q can be
set
2.
Customm_3rd: builded using 2 IInd order Cell, where Low Cut Frequency can be set on
both the cascaded Cells and the Q on the second one
3.
Customm_4th: builded using 2 IInd order Cell, where Low Cut Frequency and the Q be
set on both the cascaded Cells.
The following is an example of a HPF sub-menu screen with the filter set at 400Hz as Custom_4th
on Output1... using the name “High” (see later for assigning a Name to the outputs):
From this Page, to access the cascaded IInd order Cells, it is necessary to rotate the NAV/PM1
encoder Clockwise or Counterclockwise.
The number of accessible IInd order Cells is depending from the Custom Filter order: Custom_2nd
will allow the editing of just one IInd order Cell, Custom_3rd and Custom_4th, the access to 2 IInd
order Cells.
