• Encoders and ENTER, ESC buttons
The DPA240A Speaker Processor 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 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).
The 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.

Menu “Input A/B” Input Channels Editing [access by pushing the “A/B” buttons]
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 button and an arrow will appear on the left
of the screen “->”. Then use the “PM2” and “PM3” encoders for editing and setting the
parameter values. On some parameters that have three independent values, you will also need to
use the PM1 encoder, eg filter parameter settings.
Note: All options 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.
Audio Signal Input (A/B) Path Block Scheme
Name page – from this screen, it is possible to assign input channel a name with 6 characters
For example, name the Input A as “In L” in the Name Page:
By pressing ENTER in the Name page, user can edit the name, and there will be an arrow, as the
following screen shows:
The first character will flash.
Select character from these 6 positions by rotating “PM2” encoder and choose the desired
characters by rotating “PM3” encoder. Once the new name is defined, for example, “In A”, confirm
this new name by pressing ENTER… A new name will display on the screen, after replaced the old
one.
The following screen is shown with the new name “In A”, by replacing the previous one “In L”
N.Gate page– from this page, it is possible to set the Input Channels Noise Gate. Noise gate can
be set as “ON” or “OFF” status. The following screen is the selected “ON” status:
InputA: In L Name
Name = In L
InputA: In L Name
->Name = In L
InputA: In A Name
Name = In A

By pressing ENTER button in this page, an arrow “->” will show up on the left of the screen, and
enter into the setting interface 1 of the noise gate:
By using the “PM2” encoder, it is possible to set the noise gate as “ON” or “OFF”. By using the
“PM3” encoder, it is possible to select its attack threshold from -80dBu to -50dBu.
By rotating “NAV/PM1” encoder, user can enter into the setting interface 2 of the noise gate:
By using “PM2” encoder, user can set noise gate release time: from 10ms to 1000ms, and using
“PM3” encoder to set noise gate attack time: from 1ms to 1000ms.
Gain page – from this screen it is possible to set the Input Channels Level from -18dB to +12dB,
press ENTER button, an arrow will appear on the left of the screen “->” then use the “PM2” or
“PM3” to set parameters.
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 to
+0.0dB:
Delay page – from this page it is possible to set the Input Channels Delay Time from
000.0000mS up to 848.9984mS, by steps of 1mS or 10.4uS.
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 10.4 microseconds.
The following is an example screen for the “Delay” page where the Delay Time of Input Channel A
is set to 160.1872mS:
Phase page– from this page, it is possible to set input channels phase as “Normal” or “Invert”.
The following is an example screen of “Normal” Phase：
Input-A Name Gain
