DM Series Digital Matrix Processors

LECTROSONICS, INC.

PUSH FOR

MENU/SELECT

BACK

LCD Interface

Operation with Front Panel Controls

Some adjustments, such as levels and mute status, can

be made to DM Series processors without a computer

using the front panel LCD interface. While it is highly

recommended that the supplied DM Control Panel soft-

ware (GUI) be used, the ability to make minor adjust-

ments without a computer is often valuable.
Direct interaction with the processor is provided using

the front panel buttons, the PUSH FOR MENU/SELECT

rotary encoder control and the LCD. A variety of menus

and setup screens are provided. This interface is used

mainly for minor adjustments to rear panel input and

output levels. The GUI is used for other functions, such

as system setup and control.

Rotary encoder control. Rotate

to highlight a menu item or adjust

operating parameter and press to enter

a submenu or setup screen.

BACK button used to 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.

Boot Sequence Screens

The first screen displays the model number.
A second screen briefly displays 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.

Used with the BACK button to lock or

unlock the front panel controls.
