DPA480
User Manual

Described below are the functions of the front panel control buttons and encoders for the DPA480.
• Getting Started
As soon as the DPA480 is turned ON the device model name will appear in the LCD screen:
and a status bar will show the progress of the DPA480 initialization process:
After the first time activation, the DPA480 will show on the LCD :
4 IN 8 OUT
SPEAKER PROCESSOR
4 IN 8 OUT
4 IN 8 OUT
P01: Default

• Encoders and ENTER, ESC buttons
The DPA480 is equipped with 3 Relative Encoders, “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/C/D and 1/2/3/4/5/6/7/8 buttons
The UTILITY button allows the User to enter the Sub-menus and set the general characteristics of
the Processor. The A , B , C and D buttons allow the User to enter the Editing Menus of the
Processor's Input Channels and buttons 1, 2, 3 , 4, 5, 6, 7 and 8 allow the User to enter the
Editing Menus of the Processor's Output Channels.
The A , B , C and D buttons as well as the 1, 2, 3 , 4, 5, 6, 7 and 8 buttons have double functions
dependent on the push and hold time.
When the A , B , C and D buttons are pushed and held for more than one second Input Channels
A or B or C or D 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 , B , C and D 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 , 4, 5, 6, 7 and 8 buttons are pushed and held for more than one second the
Output Channels 1, 2, 3 , 4, 5, 6, 7 and 8 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 , 4, 5, 6, 7 and 8 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.
• DPA480 Menu and Sub-Menu Structures
As stated above, the start-up default screen is the following factory preset:
From this point, sub-menus are accessed and exited using the UTILITY”, “A/B/C/D”,
“1/2/3/4/5/6/7/8”, “ENTER” and “ESC” buttons and all parameters and values are navigated by
the “PM1”, “PM2” and “PM3” encoders. Please refer to the following menu structures:

Menu “UTILITY” [access by pushing the “UTILITY” button]
From the “Default Screen”, it is possible access the “UTILITY” menu pushing the “UTILITY” button
and the Sub-Menus pages can be selected just rotating clockwise and counter-clockwise the
“PM1” encoder.
Once selected the sub-menu page, using the “ENTER” button can be accessed the Sub-Menus
pages, again “scrollable” using the “PM1” encoder and accessible for the parameters' editing
pushing again the “ENTER' button.
Note: In each sub-menu choice, the current selected or running choice is what shown on the LCD
screen.
System Utilities Sub-menu – this sub-menu allows to access several operations related to the
DPA480 Start Up and General Configuration:
UTILITY MENU:
From the “System Utilities Sub-menu”, pushing “ENTER” and then using the “PM1” encoder for
scrolling will give access to the following pages:
−Input Source:the DPA480 is equipped with 4 Analog Inputs (Balanced Female XLR) and 2
AES Digital Input (RCA connector).and noise generator
The “Input Source” page allows you to select the desired Input type:
By pressing ENTER on Input Source and then rotating the “PM2” or “PM3” encoders, it is
possible to select the Main Inputs for the DPA480, allowing the User to choose between
Analog , AES Digital Input or Noise Generator.
The selection can be confirmed by pressing the “ENTER” button.
The following screen shows that the Analog Input has been selected:

−Noise Generator:DPA480 equips with 2 types of noise generator: White Noise and Pink
Noise.
By pressing ENTER and rotating the “PM2” encoder, it is possible to select between those 2
choice: “Pink” or “White”. By rotating the “PM3” encoder, it is possible to set the value of level
of white noise generator and pink noise generator, with whose range from 0dB to -40dB.
The following screen shows the selected pink noise with level of -20dB:
Delay Units: this page allows you to select the measurement unit to be used for the Delays:
Time (in milliseconds “ms”) or Distance (in meters “m”):
By pressing ENTER button and rotating the “PM2” or “PM3” encoder, it is possible to select the
measurement unit to be used for the delay, which will be confirmed by pushing the ENTER
button.
The following screen shows the selected delay measurement is Time (milliseconds)
Set Default Value: All setting for DPA480 can be set to default value:
By pressing ENTER button, will show up the following screen of an interface to confirm to set
the default value:
By pressing ENTER button one more time, will show up the following screen:
