2 In - 4 Out Speaker Management System
Introduction
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.

Described below are the functions of the front panel control buttons and encoders for
the DPA240P.
•
Getting Started
As soon as the DPA240P is turned ON the device model name will appear in the LCD screen:
DPA240P
Speaker Management
and a status bar will show the progress of the DPA240P initialization process:
DPA240P
The DPA240P has three factory pre-set working modes: “1x2 Ways Xover” and
“4 Ways Xover”
After the initialization, the DPA240P will show on the LCD the first of the embedded preset
working modes, or the last one selected prior to the unit being turned off.
First time activation will default to the first of the preset working modes.
DPA240P
1x2 WAY XOVER
2 In - 4 Out Speaker Management System
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.
UTILITY, A/B and 1/2/3/4/5/6 buttons
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 buttons are pushed and held for more than one second the Output
Channels 1, 2, 3 and 4 are 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.
DPA240P Menu and Sub-Menu Structures
As stated above, the start-up default screen is the following factory preset:
DPA240P
2x3 WAY XOVER
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:

Input and Output Channels Last Edited Parameter Return Function
Once you have escaped out of parameter editing within the individual Input or Output channels
the DPA240P will remember this last editing action on that Channel. When you return for your
next editing action pressing the EDIT button on that channel will immediately return you to the
screen related to this last editing action.
This function makes fine tuning or modifying easier when it is necessary to make a number of
adjustments to the same parameter in a short time sequence.
Input Channels and output Channels LINK Function
The DPA240P is able to perform a unique LINK MODE between Input Channels as well as a link
between Output Channels to enable quick and immediate editing (you cannot link output to input
channels).
To link channels when editing, you will need to select a“Master”channel that will be the one to be
edited and have it’s parameters displayed on the LCD screen. You can then select and link other
channels (Slaves) that you wish to apply the same changes to.
To enter a link mode session, select the Master channel Edit mode, then link the Slaves by
pressing their related Edit buttons.
All Linked channels will be selected ready for adjustment when their“Blue”LED is lit in the Editing
mode.
Now all Slave channels and only those selected will modify their parameters accordingly as you
edit the Master channel.
All other existing parameters will stay the same within the Slave Channels unless edited by this
link with the Master channel.
Note: The LINK function is NOT a COPY function.
If we want to edit the limiter of the Output channels 1/2/4, we can enter the editing mode of
Output Channel 1 by pressing the related Edit button and turning on the Blue LED below the
Output Channel 1 LED meters. This assigns the “role” of Master and displays this channel’s
parameters on the LCD:
Out-1
Name
Limiter
A: 5ms R: 0.2s +5.0dB
Then press the Edit button of Output Channels 2/4, turning on their related“Blue”LED’s. Now all
parameters edited on Output Channel 1, will also be applied to channels 2 and 4.
If we want to remove one of the linked channels from the Link, press the related Edit button.
Exiting the editing of the Master channel during a Link session will automatically terminate that
session. The Link will also be automatically terminated if, during the editing of Output Channels
you jump across to begin editing an Input channel or vice versa.

Factory Reset
In the event of the password being lost or any other reason the user may require the unit to be
reset to the original factory settings, a“ Factory Reset ” that will clear all settings of the DPA240P
and return the device to the original factory setting, is available to the user.
Note: Continuing with this process will mean the DPA240P will re-initialize to the original factory
settings and any previously stored information and changed parameters will be permanently lost.
–
Use the following procedure to perform the factory reset:
1. While the DPA240P is switched OFF, simultaneously press the ENTER+ESC+UTILITY
buttons on the front panel.
2. Maintain pressure on all three buttons as you turn the power switch to On and the
following LCD screen appears on the DPA240P:
Please Wait......
Memory Reset
3. Release the buttons and wait for the DPA240P to re-initialize.
Once completed, the DPA240P will resume regular operation as though it was a new unit from
the factory and no previously programmed parameters will be available for use.

The DPA240P's microcontroller will check if the Preset is initialized (available or not yet
created...)
B. If YES, then the microcontroller will send back to the User (eg Crestron/AMX Remote Control..)
the same frame used by the command
