The available shapes and orders for the Low Pass Filter that are accessible by rotating the
encoder
“PM3”
are listed below:
- No Cut-Off (Low Pass Filter Bypassed)
- Butwrth 6dB (Butterworth Filter 6dB/Oct Slope)
- Butwrth 12dB (Butterworth Filter 12dB/Oct Slope)
- Lnk/Ril 12dB (Linkwitz/Riley Filter 12dB/Oct Slope)
- Bessel 12dB (Bessel Filter 12dB/Oct Slope)
- Butwrth 18dB (Butterworth Filter 18dB/Oct Slope)
- Butwrth 24dB (Butterworth Filter 24dB/Oct Slope)
- Lnk/Ril 24dB (Linkwitz/Riley Filter 24dB/Oct Slope)
- Bessel 24dB (Bessel Filter 24dB/Oct Slope)

: Once the desired options have been selected using the 2 encoders, they are automatically saved as
current and stored in the DS-CP25 system status once leaving the page.

- from this sub-menu it is possible to set the Input Channels 5 available Peaking or
Shelving Filters.
The DS-CP25 allows the user to select either Peaking or Shelving Parameters and assign them
independently using the 5 available filters.
In order to select the filter’s type, it is necessary to have the filter’s GAIN=0.0dB, then using the “PM2”
encoder, rotate it “clockwise” in order to decide the Peaking filter’s Bandwidth, or “counter-clockwise” to
select the Shelving filter type (Low or High) and its order (1
or 2nd).

So, in order to define the filter type for the filter number 1 ( “x” = 1), it is necessary from the above screen,
to enter the filter’s editing page pressing the “ENTER” button, and the screen has to appear as follows:
In this case, the filter’s GAIN=0.0dB, and being BW=1.05, the current filter selected is a Peaking type.
Now, rotating the “PM2” encoder clockwise, the parameter BW will range from 0.05 up to 3 for identifying a
bandwidth value for a Peaking filter.
If a Peaking filter is selected, then the Gain can be modified from 0.0dB and the BW will range between
0.05 and 3.
If the user wants to select a Shelving filter from the above setting, with the GAIN=0.0dB [if the GAIN is not
0.0dB, it is necessary to set it at 0.0dB using the “PM3” encoder], rotate the “PM2” counter-clockwise. Once
BW reaches the 0.05 value, at the next step of the “PM2” counter-clockwise rotation, the selection of the
Shelving filters will be entered.
