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:

and a status bar will show the progress of the DPA240P initialization process:

The DPA240P has three factory pre-set working modes:

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.

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:
