2 In - 4 Out Speaker Management System
DPA240P is a cost-effective 2-IN/4-OUT digital speaker management system. Designed to be catered for any
crossover configuration, it provides the suitable processing and control for live application use. It offers 2 analog
inputs,and 4 analog outputs, managed by a powerful DSP Engine, in addition to 24 Bit AD/DA Converters. Each
input channel provides a choice of EQ with a 5-band Parametric EQ, gain control, noise gate function and
configurable delay. Each output offers up to 5-band of parametric equalization in to the crossover filters which
themselves provide slopes from 6dB/Octave up to 48dB/Octave. Each output path also features peak limiter and
driver alignment delay. The DPA240P supports a full matrix mixing mode where inputs may be routed/mixed in any
ratio to any output. For remote configuration and control the DPA240P can be connected via USB or Rs485
connections. The control remote PC software allows simultaneous control up to 32 units, setting all parameters
and showing real time levels.

Encoders and ENTER, ESC buttons
The DPA240P is equipped with 3 Relative Encoders, “NAV/PM1”, “PM2” and “PM3”, These
encoders allow you to navigate the user interface and edit sections of the processor. They allow
the user to navigate within the screen for the selection of sub-menus, pages and parameters and
to select the values to be assigned during the editing operations.
The “ENTER” and “ESC” buttons allow the user to confirm or NOT confirm the operations
performed by the encoders.
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of
the Processor. The A and B buttons allow the User to enter the Editing Menus of the Processor's
Input Channels and buttons 1, 2, 3 and 4, allow the User to enter the Editing Menus of the
Processor's Output Channels.
The A and B buttons as well as the 1, 2, 3 and 4 buttons have double functions dependent
on the push and hold time.
When the A and B buttons are pushed and held for more than one second Input Channels A or B
are either muted or unmuted. The red LED will illuminate when the Channel is muted. When the
“MUTE” LED is OFF, then the related Input Channel is UN-MUTED.
A momentary push of the A and B buttons enters the Editing Mode for the Input Channels (see
later for the Input Channel Editing details).
Th e blue “EDIT” LED will now be ON.
When the 1, 2, 3 and 4 b uttons are pushed and held for more than one second the Output
Channels 1, 2, 3 and 4 a re either muted or unmuted. The red LED will illuminate when the
Channel is muted. When the “MUTE” LED is OFF, then the related Output Channel is UN-MUTED.
A momentary push of the 1, 2, 3 and 4 buttons enters the Editing Menu for the Output
Channels (see later for the Output Channel Editing details). The blue “EDIT” LED will now be ON.
As stated above, the start-up default screen is the following factory preset:
From this point, sub-menus are accessed using the UTILITY”,“A/B”,“1/2/3/4”,“ENTER” and
“ESC” buttons and all parameters and values are navigated by the “NAV/PM1”,“PM2”and“PM3”
encoders. Please refer to the following menu structures:

From the “Default Screen”, it is possible to access the “Input A/B” menu by pushing the “A” or
“B” button. Once the button is pressed the related blue “EDIT” LED will turn ON. The Sub-
Menu pages can now be scrolled through by rotating clockwise and counter-clockwise the
“NAV/PM1” encoder.
For parameter editing it is necessary to press ENTER and an arrow will appear on the left of
the screen “->”. Then use the “PM2” and “PM3” encoders for selecting and setting the
parameter values. On some parameters that have three independent values, you will also need
to use the NAV/PM1 encoder, eg filter parameter settings.
Note: All parameter editing can be done using the “NAV/PM1”, “PM2”, and “PM3” encoders
and the current shown value of the selected option is AUTOMATICALLY loaded during the
encoders' use and stored as the current value once leaving the page is AUTOMATICALLY loaded
during the encoders' use and stored as current value once left the page.
Note1: once the desired options have been selected using the 3 encoders, they are
automatically saved as current and stored in the DPA240P system status once leaving the
page.
Note2: to exit this page, push the “ESC” button.
Gain page – from this screen it is possible to set the Input Channels Level from -15dB to
+15dB, press ENTER an arrow will appear on the left of the screen “->” then use the “PM2”
or “PM3” buttons.
The value set on this screen will only affect the input level of the selected Channel A or B.
The following is an example screen for the “Gain” page that has set the Gain of Input Channel
A, named as Input1, to +0.0dB:
Delay page – from this page it is possible to set the Input Channels Delay Time from
000.0000mS up to 399.0000mS, by steps of 1mS or 20.8uS.
To set the Delay time press ENTER, an arrow will appear on the left of the screen “->”. then
use the “PM2” encoder to set the Delay Time in steps of 1mS and the “PM3” for setting the
“fine” Delay Time in steps of 20.8 microseconds.
The following is an example screen for the “Delay” page where the Delay Time of Input Channel

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

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 -12dB to +12dB 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:
Lo_Shelv_Q Filter: These Symmetrical Shelving filters present ½ level of the selected
Gain/Attenuation at the selected cutting frequency, and a slope depending from the chosen Q
value.
If we selected a Low 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 using the PM3 and the Hi Cut
