Lo_Shelv_1/2 Filter: These Shelving filters present 3dB less than the selected Gain, or 3dB
more than the selected Attenuation, at the selected cutting frequency, and a slope of 6dB/Oct-
12dB/Oct.
If we selected a Low Shelving filter of the 1st/2nd order within EQ-1, then the GAIN has to be set
at a desired value of say +3dB using the Param.2 encoder and the High Cut Frequency at say
1000Hz with the NAV/Param.1 encoder; the EQ sub-menu screen will show the following:
Once in the Lo-Shelv_1/2 Filter's edit screen, all the filter's parameters can be modified using the
“NAV/Param.1” and “Param.2” encoders for editing the Filter's High Cut Frequency and Gain:
“
High Cut 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.
“
Gain ”: the selectable range of the Gain is from -15dB to +15dB in steps of 0.5 dB and can be
adjusted by rotating the “Param.2” 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.
Lo_Shelv_Q Filter: These Symmetrical Shelving filters present ½ level of the selected
Gain/Attenuation at the selected cutting frequency, and a slope depending from the chosen Q
value.
If we selected a Low Shelving filter with variable Q within EQ-1, then the GAIN has to be set at a
desired value of say +3dB using the Param.2 encoder, the Q at 3.5 using the Param.3 and the Hi
Cut Frequency at say 1000Hz with the NAV/Param.1 encoder; the EQ sub-menu screen will show
the following:
Once in the Lo-Shelv_Q Filter's edit screen, all the filter's parameters can be modified using the
“NAV/Param.1”, “Param.2” and “Param.3” encoders for editing the Filter's High Cut Frequency,
Gain and Q:
“ High Cut 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.
“ Gain ”: the selectable range of the Gain is from -15dB to +15dB in steps of 0.5 dB and can be
adjusted by rotating the “Param.2” 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.
