Still rotating the “PM2” counter-clockwise, the Shelving filters and their order will be selectable in the 
following sequence:

1. 1st Order Low Shelving = -6LoSh [on the screen]
2. 2nd Order Low Shelving = -12LoSh [on the screen]
3. 1st Order High Shelving = -6HiSh [on the screen]
4. 2nd Order High Shelving = -12HiSh [on the screen]

Once the desired 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.

Peaking Filter

 - As an example, if we want to set a Peaking filter within EQ-1, then the BW has to be set at 

a desired value of say 1.00 using the “PM2” encoder, the GAIN at say +3dB using the “PM3” 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 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 1/12 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 0.5dB and can be adjusted by 

rotating the 

encoder.

“PM3” 

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.
