[ROUTING]: you can use this button to select the type of connection between the two filters,
as follows:
The selection made will be shown by illumination of the corresponding LED.
•
[FILTER 1]: sets the type of filter, as follows:
-
LP (Low Pass Filter): you can use this filter to attenuate all the frequencies above the cut-
off frequency, giving a darker, softer sound.
- HP (High Pass Filter): you can use this filter to attenuate all the frequencies below the cut-
off frequency, giving a sharper, brighter sound.
-
BP (Band Pass Filter): you can use this filter to attenuate all the frequencies not present
in the area surrounding the cut-off frequency.
The LED against the code identifying the type of filter illuminates to display the selection has
been made. If no LED is on, the filter will be disabled (FLAT condition).
•
[FILTER 2]: the procedure for selecting the type of the second filter is identical to that described
for [FILTER 1].
The behaviour of the various types of filters is described in the next page.
