MEA2100-System Manual
The settings for the high pass and the low pass filter are explained via tool tips:
Select the order of the filter from the first drop down box. The message "The filter order
determines the steepness of the filter" is shown. The higher the order, the steeper the cut off.
Select the cut off frequency of the filter from the second drop down box. The message "The
cut off frequency of the filter. The amplitude is reduced by 3 db at this frequency. A filter with
Bessel characteristic is used." is shown. The option "Custom" can not be selected. If you need
a frequency which is not available on the list, please contact support@multichannelsystems.com.
The selected settings are automatically downloaded to the MEA2100 device as soon as you select
them. If the "Make Permanent" button is not used, the device will be back to the last saved
settings after a reset.
Click the button "Make Permanent" to store the selected filter settings permanently.
Click the button "Defaults" to refresh the factory default settings.
