EQ: [x] sub-menu – from this sub-menu it is possible to set the Input Channels five available
Parametric or Shelving Filters.
The DPA-260A allows the user to select either Bell or Shelving Parameters and assign them
independently using the 5 available filters.
In order to select the filter's type, it is necessary to have the filter's GAIN=0.0dB, then using the
PM2 encoder, rotate it "clockwise" in order to decide the Bell filter's Bandwidth, or "counter-
clockwise" to select the Shelving filter type (Low or High) and its order (1
So, in order to define the filter type for the filter number 1 ("x"=1), it is necessary from the above
screen, to enter the filter's editing page pressing the ENTER button, and the screen has to appear
as follows:
In t this case, the filter's GAIN=0.0dB, and being BW=1.05, the current filter selected is a Bell
type
Now, rotating the PM2 encoder clockwise, the parameter BW will range from 0.05 up to 3 for
identifying a bandwidth value for a Bell filter.
If a Bell filter is selected, then the Gain can be modified from 0.0dB and the BW will range
between 0.05 and 3.
If the user wants to select a Shelving filter from the above setting, with the GAIN=0.0dB [if the
GAIN is not 0.0dB, it is necessary to set it at 0.0dB using the PM3 encoder], rotate the PM2
counter-clockwise. Once BW reaches the 0.05 value, at the next step of the PM2 counter-
clockwise rotation, the selection of the Shelving filters will be entered.
Still rotating the PM2 counter-clockwise, the Shelving filters and their order will be selectable in
the following sequence:
1. 1
st
order Low Shelving = -6LoSh [on the screen]
2. 2
nd
order Low Shelving = -12LoSh [on the screen]
3. 1
st
order High Shelving = -6HiSh [on the screen]
4. 2
nd
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.
