The DPA880 allows the user to select either Bell or variable Q Shelving Parameters and assign
them independently using the 3 available filters.
The selection can be done just pressing the “Peak Eq” button on top of the filters' gain sliders and
selecting one of the 3 available filters' type: Peaker, variable Q high Shelving and variable Q low
Shelving.
BELL Filter: here Center Frequency, Band Width (Q) and Gain can be adjusted.
“ Center Frequency ”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of
an Octave.
“
Bandwidth BW ”: the selectable BW range is from 0.0312 Octave (Q=10) up to 3.59 Octave
(Q=0.4) in steps of 0.1 Q.
“
Gain ”: the selectable Gain range is from -12dB to +12dB in steps of 0.5 dB.
Variable Q Low Shelving Filter: here Center Frequency, Band Width (Q) (Slope) and Gain can
be adjusted.
“
Center Frequency ”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of
an Octave.
“
Bandwidth BW (Slope) ”: the selectable BW range is from 0.0312 Octave (Q=10) up to 3.59
Octave (Q=0.4) in steps of 0.1 Q.
“
Gain ”: the selectable Gain range is from -12dB to +12dB in steps of 0.5 dB.
Variable Q High Shelving Filter: here Center Frequency, Band Width (Q) (Slope) and Gain can
be adjusted.
“
Center Frequency ”: the selectable frequencies range is from 20Hz to 20kHz in steps of 1/24 of
an Octave.

Bandwidth BW (Slope) ”: the selectable BW range is from 0.0312 Octave (Q=10) up to 3.59
Octave (Q=0.4) in steps of 0.1 Q.
“
Gain ”: the selectable Gain range is from -12dB to +12dB in steps of 0.5 dB.
Note : each single filter can be independently “bypassed” for an easy setting/use of them.
To “Bypass” the single filter, just press the “Bypass” button below the filter’s parameters.
In order to set, if necessary, more Eq of the 8 input channels in tha same way, “Input Linked”
buttons are available and, when pressed, force the all channels corresponding to the pressed
buttons to set the Eq in the same as as the one set for the currently edited channel (which has to
be one of the linked ones)
The set up of the filters and specially their frequency placement can also be done with the use of
the mouse, just activating the “Show Cursor” function, pressing the related button on the left
bottom of the frequency response Graphic.
