LPF sub-menu –
from this sub-menu it is possible to set the Output Channels Low Pass Filter
(LPF).
The following is an example of a LPF sub-menu screen with the filter set at 24dB Linkwitz/Riley on
Output1... using the name “Low” (see later for assigning a Name to the outputs):
The filter's parameters can be modified by use the “PM2” and “PM3” encoders for editing the
Filter's High Cut Frequency and the Filter's Type and Order.
The High Cut Frequency of the Low Pass Filter can be edited using the “PM2” encoder and the
Filter's Type and Order can be edited by using the “PM3” encoder.
“
High Cut Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24
of an Octave and can be adjusted by rotating the “PM2” encoder.
“
Low Pass Type and Order
”: this page allows you to select the X-Over's Low Pass Filter Shape
and Order.
The available shapes and orders for the Low Pass Filter that are accessible by rotating the “PM3”
encoder 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)
Note1:
Once the desired options have been selected using the 2 encoders, they are automatically
saved as current and stored in the DS-SP24 system status once leaving the page.
Note2:
To exit this page, push the “ESC” button.
EQ: [x] sub-menu –
from this sub-menu it is possible to set the Output Channels seven available
Parametric or Shelving Filters.
The DS-SP24 allows the user to select either Bell or Shelving Parameters and assign them
Independently using the 7 available filters.
