EQ Byp page – from this sub-menu it is possible to Bypass or to make active the 5 Bands
Equalizer placed on the Input Signal Path.
When Bypassed the 5 Bands Equalizer, its current setting will not be lost.
EQ: [x] sub-menu – from this sub-menu it is possible to set the Input Channels five available Multi-
Type Filters.
Anyone of the 4 filters of the Eq can be selected choosing from the following list of filter types:
1.
Peaking_Eq: Peaking (Bell) filters, adjustable as Center Frequency, Gain and Q
The DPA240P Peaking filters are at constant Q, so with Q not depending from the selected Gain value.
2.
Hi-Shelv_Q: Symmetrical High Shelving filters with Variable Q.
These 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.
3.
Lo-Shelv_Q: Symmetrical Low Shelving filters with Variable Q.
These 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.
4.
All Pass_2: Filters allowing a FLAT Amplitude response and adding a 180 Degree Phase rotation at the
selected Frequency.
More, the DPA240P Is giving the possibility to “Bypass” any single filter of the 4 available in the
Equalizer section; Once in the editing page of the single filter, a “Byp” field is available for making
the single filter active or not
Pushing the Enter Button, the above window will allow the access to the “Byp” and “Type” fields.
Using the PM2 encoder, the selected Filter can be activated or bypassed.
The DPA240P allows the user to select anyone of the filter's type listed above and assign them
independently using the 5 available filters.
In order to select the filter's type, it is necessary to use the PM3 encoder, rotate it “clockwise”
or “counter-clockwise” to select the desired filter.
So, in order to define the filter type for the filter number 1 (“x”=1), it is necessary from the
above screen, to select the filter, which name will appear on the screen.
If selected a Peaking_Eq filter, then the display will be as follow:
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
