Reference Manual for Operation

Rio Rancho, NM – USA

LCD Interface

Operation with Front Panel Controls

Some adjustments, such as levels and mute activity, can
be made to DM Series processors without a computer
using the front panel LCD interface.  While it is highly
recommended that the supplied GUI software be used,
the ability to make minor adjustments without a com-
puter is often valuable.

Direct interaction with the processor is provided using
the front panel buttons, the rotary encoder knob and the
LCD.  A variety of menus and setup screens are pro-
vided.  This interface is used mainly for adjustments to
input and output levels.  Use the GUI for other functions.

Boot Sequence Screens

The first screen displays the model number.

A second screen is then displayed briefly showing the
serial number and the firmware version.

The display then returns to the first screen showing the
model number, indicating that the unit has completed
boot sequence and is running.

Press the rotary encoder knob to move to the Top Menu
after the boot sequence is completed.

PUSH FOR

MENU/SELECT

BACK

Rotary encoder control.  Rotate to
select menu item and press to enter
the submenu or setup screen.

“Back” button used to save settng
and return to previous menu.

Item select buttons used on setup screens.

NOTE:

Adjustments made with the LCD controls are real time.  As each setting is
made, the result will be heard immediately.
