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/PAR1 encoder.
The EQ sub-menu screen will show the following
Input-A
EQ-1
->1.00kHz -6HiSh
+ 3.0dB
Note: Once the desired High 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 High Shelving Filter's edit screen all the filter's parameters can be modified using the
"NAV/PAR1","PM2"and"PM3"encoders for editing the Filter's Low Cut Frequency, Filter's Order
and Gain.
The Lo Cut Frequency of the High Shelving Filter can be edited using the "NAV/PAR1" encoder, the
Filter's Order can be adjusted by the "PM2" encoder and the Gain the "PM3" encoder:
"Lo 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/PAR1" encoder.
"High Shelving Order ": the selectable High Shelving Filter's range can be selected between the
1
(Lo-1st.) and the 2
(Lo-2nd.) one.
st
nd
"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.
Note1 : once the desired options have been selected using the 3 encoders, they are automatically
saved as current and stored in the DPA-260A system status once leaving the page.
Note2 : to exit this page, push the "ESC" button.
