Once selected the desired Filter Type, its parameters can be accessed for editing just pressing again the ENTER
Button.
Once pressed the ENTER Button, the editing page of the selected filter type will be accessed ONLY if the selected
filter it is not set in Bypass mode.
Depending from the selected filter, the related parameters will be available for editing
Peaking_Eq Filter:
Peaking filters are at constant Q, so with Q not depending from the selected Gain value
If we selected a Peaking_Eq filter within EQ-1, then the Q has to be set at a desired value of say 1.00 using the
PM3 encoder, the GAIN at say +3dB using the PM2 encoder and the center Frequency at say 1.00KHz with the
NAV/PM1 encoder; the EQ sub-menu screen will show the following:
Once in the Peaking_Eq 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, 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/PM1” encoder.
“
Gain
”: the selectable Gain range is from -15dB to +15dB in steps of 0.5 dB and can be adjusted by rotating the
“PM2” 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 “PM3”
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/PM1” encoder will increment/decrement the Frequency value by step of one thousand Hz, the PM2
by steps of one hundred Hz and the PM3 by steps of one Hz..
Hi_Shelv_Q Filter:
These Symmetrical Shelving filters present ½ level of the selected Gain/Attenuation at the
selected cutting frequency, and a slope that is depending from the chosen Q value.
If we selected a High Shelving filter with variable Q within EQ-1, then the GAIN has to be set at a desired value of
say +3dB using the PM2 encoder, the Q at 3.5 and the Lo Cut Frequency at say 1000Hz with the NAV/PM1
encoder; the EQ sub-menu screen will show the following:
Once in the Hi-Shelv_Q 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 Low Cut Frequency, Gain and Q:
“
Low Cut Frequency
”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1Hz and can be
adjusted by rotating the “NAV/PM1” 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 “PM2” 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 “PM3”
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:
Input-A EQ-1
->1.00kHz +3.0dB Q=1.00
Input-A EQ-1
->Edit Freq = 1000Hz
Input-A EQ-1
->1000Hz +3.0dB Q= 3.5
Input-A EQ-1
->Edit Freq = 1000Hz
