Once in the Bell Filter's edit screen all the filter's parameters can be modified using the
“NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter's Center Frequency, Bandwidth BW
and Gain.
The Center Frequency of the Parametric Filter can be edited using the “NAV/PM1” encoder, the BW
the “PM2” encoder and the Gain the “PM3” encoder:
“
Center Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of an
Octave and can be adjusted by rotating the “NAV/PM1” encoder.
“
Bandwidth BW
”: the selectable BW range is from 0.05 Octave to 3 Octave in steps of 0.05 Octave
and can be adjusted by rotating the “PM2” encoder.
“
Gain
”: the selectable Gain range is from -15dB to +15dB in steps of 0.5 dB and can be adjusted by
rotating the “PM3” encoder.
Low Shelving Filter:
As an example if we want to set a low shelving filter within EQ-1 then the
“PM2” encoder has to be rotated counter-clockwise until the desired Low Shelving filter say -6LoSh
appears on the screen, the GAIN at say +3.0dB using the “PM3” encoder and the High Cut
Frequency at say 1.00KHz with the NAV/PM1 encoder.
The EQ sub-menu screen will show the following:
Note:
Once the desired Low Shelving filter is selected, the “PM3” can then be used to select the
desired GAIN and when the GAIN is set at a value different from 0.0dB, then the filter type cannot
be changed until this GAIN is returned to 0.0dB.
Once in the Low Shelving Filter's edit screen all the filter's parameters can be modified using the
“NAV/PM1”, “PM2” and “PM3” encoders for editing the Filter's High Cut Frequency, Filter's Order
and Gain.
The Hi Cut Frequency of the Low Shelving Filter can be edited using the “NAV/PM1” encoder, the
Filter's Order can be adjusted by the “PM2” encoder and the Gain the “PM3” encoder:
“
Hi Cut Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of an
Octave and can be adjusted by rotating the “NAV/PM1” encoder.
“
Low Shelving Order
”: the selectable Low Shelving Filter's range can be selected between the 1st
(Lo-1st.) and the 2nd (Lo-2nd.) one.
“
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 “PM3” encoder.
High Shelving Filter:
As an example if we want to set a high shelving filter within EQ-1 then the
“PM2” encoder has to be rotated counter-clockwise until the desired High Shelving filter say -
6HiSh appears on the screen, the GAIN at say +3dB using the “PM3” encoder and the Low Cut
Frequency at say 1.00KHz with the “NAV/PM1” encoder.
