All Pass_1 Filter:
Filters allowing a FLAT Amplitude response and adding a 90 Degree Phase
rotation at the selected Frequency.
If we selected a All Pass filter of the 1st order within EQ-1, then Phase Rotation Frequency has to
be set at a desired value of say 1000Hz with the NAV/Param.1 encoder; the EQ sub-menu screen
will show the following:
Once in the All Pass_1 Filter's edit screen, the “NAV/Param.1” encoder can be used for
editing/modifying the Filter's Phase Rotation Frequency:
“
Phase Rotation Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps
of 1Hz and can be adjusted by rotating the “NAV/Param.1” encoder.
When in the Parameters Editing Page, pushing once more the ENTER Button, it is possible to
access the page of the
Frequency Fast Setting
:
Here, the NAV/Param.1” encoder will increment/decrement the Frequency value by step of one
thousand Hz, the Param.2 by steps of one hundred Hz and the Param.3 by steps of one Hz.
All Pass_2 Filter:
Filters allowing a FLAT Amplitude response and adding a 180 Degree Phase
rotation at the selected Frequency.
If we selected a All Pass_2 filter, with variable Q, within EQ-1, then Phase Rotation Frequency has
to be set at a desired value of say 1000Hz with the NAV/Param.1 encoder and the Q at 3.5 using
the Param.3 encoder; the EQ sub-menu screen will show the following:
Once in the All Pass_2 Filter's edit screen, all the filter's parameters can be modified using the
“NAV/Param.1” and “Param.3” encoders for editing the Filter's Phase Rotation Frequency and Q:
“
Phase Rotation Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps
of 1Hz and can be adjusted by rotating the “NAV/Param.1” encoder.
“
Q
”: the selectable Q range is from 0.3 up to 20.0 in steps of 0.1 and can be adjusted by rotating
the “Param.3” encoder.
When in the Parameters Editing Page, pushing once more the ENTER Button, it is possible to
access the page of the
Frequency Fast Setting
:
Here, the NAV/Param.1” encoder will increment/decrement the Frequency value by step of one
thousand Hz, the Param.2 by steps of one hundred Hz and the Param.3 by steps of one Hz.
