Band Pass Filter: Filters allowing to pass the band “around” the selected frequency; the amount
of passing band is decided by the Q value
I
f we selected a Band Pass filter within EQ-1, then the Q has to be set at a desired value of say
1.00 using the Param.3 encoder, the GAIN at say +3dB using the Param.2 encoder and the center
Frequency at say 1.00KHz with the NAV/Param.1 encoder; the EQ sub-menu screen will show the
following:
Once in the Band Pass 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 Center Frequency, Gain
and Q:
“ Center 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 Gain range 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.
Notch Filt Filter: Filters canceling the band “around” the selected frequency; the amount of
canceled band is decided by the Q value
I
f we selected a Notch Filt filter within EQ-1, then the Q has to be set at a desired value of say
1.00 using the Param.3 encoder and the Notch Frequency at say 1.00KHz with the NAV/Param.1
encoder; the EQ sub-menu screen will show the following:
Once in the Notch Filt 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 Notch Frequency and Q:
“ Notch 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
