DN9848 Menu System

4.PROGRAMMING SETTINGS

4.1. The DN9848 Programming Panel

All the parameters for input and output signal processing and routing are defined via function specific menu pages that are displayed and edited at the programming panel shown below. As described in the illustration, each menu page uses a standard layout that relates the displayed parameters to the three DATA ENTRY encoder knobs, which are used to adjust the parameter values.

The DATA ENTRY encoder knobs adjust the left, centre and right parameter values at the display, in corresponding order. If there are only one or two parameters, only the active controls are lit.

When the menu page requires text entry, ‘<>’ indicates which knob moves the cursor left and right while ‘chr’ indicates which knob changes the alpha numeric character.

The adjustable parameters are named on the top line. Current values are given below in corresponding order.

When there are sub-menu pages either the left of right knob will be allocated to moving forward ( - - >) or back up ( < - -). This will be indicated here by a knob icon marked L (Left) or R (Right).

The icon indicates that turning the left knob will access the sub-menu page.

4.2. Navigating the DN9848 Menus

The DN9848 menu system is divided logically into Input, Output and Set Up menus, plus two function specific menus for quick access to the Store and Recall commands. A menu map is provided at the end of this section for reference purposes.

4.2.1Input and Output Menus

Each of the four input channels (A-D) and eight output channels (1-8) has their own set of menu pages, accessed and stepped through by pressing the channel’s yellow MENU ACCESS button. When you select a channel, its button lights to show that this channel is currently active at the programming panel. In addition, all the menu pages show the channel number/letter in the top left-hand corner.
