Local Operation with Front-Panel Display & Buttons (DADS-1)

Default display

This mode uses the front-panel LCD and 7 control buttons. This is for stand-alone operation where the DADS-01 status outputs are connected to external alarm monitoring inputs.

After the splash screen, the screen below shows the display that would typically appear on the DADS-01 during normal operation. The first line displays the input source numbers (1 and 2 for digital and 3 for analog) as well as a simple vertical bar graph indicator showing the levels of the left and right channel on each source.

The second line shows the highest audio level that can be found on the left or right channel for each input source. The minimum value that can be displayed for the digital inputs (1 and 2) is -140 dBFS and the minimum value for the analog input is approximately -105 dBFS.

The exclamation mark is used to indicate a problem with the associated digital input source. This happens in the case of an invalid stream or in the case of no signal.

Menu selection mode

Pressing the MENU button once will display the first menu item. Pressing the UP (or DOWN) button after the first MENU press scrolls to the next (or preceding) menu item. Pressing a second time selects that menu item and allows it to be modified by pressing the UP or DOWN buttons. The desired value being set, pressing MENU again will activate the setting and display the main menu. The table below presents the menu items in their order and their possible settings.

UP/DOWN steps First press on MENU Description / Value
1 Test Tone Activates test tone / Off or ON
2 CH1 Low Level CH1 Low level threshold / 0 to -99 dBFS
3 CH1 Normal Level CH1 Normal level threshold / 0 to -99 dBFS
4 CH1 Low Lvl Dly CH1 Low Level Delay / 0 to 99 s
5 CH1 Norm Lvl Delay CH1 Normal Level Delay / 0 to 99 s
6 CH2 Low Level CH2 Low level threshold / 0 to -99 dBFS
7 CH2 Normal Level CH2 Normal level threshold / 0 to -99 dBFS
8 CH2 Low Lvl Dly CH2 Low Level Delay / 0 to 99 s
9 CH2 Norm Lvl Delay CH2 Normal Level Delay / 0 to 99 s
10 CH3 Low Level CH3 Low level threshold / 0 to -99 dBFS
11 CH3 Normal Level CH3 Normal level threshold / 0 to -99 dBFS
12 CH3 Low Lvl Dly CH3 Low Level Delay / 0 to 99 s
13 CH3 Norm Lvl Delay CH3 Normal Level Delay / 0 to 99 s

1- Test Tone: Outputs two signal tones, one at 1 kHz on the left channel and one at 400 Hz on the right channel.

2- CHX Low Level: Signal level below which the input source will be considered in error (no audio).

3- CHX Normal Level: Signal level above which the input source will be considered normal.

4- CHX Low Level Delay: The time the signal level must be below the low level threshold before declaring a fault.

5- CHX Normal Level Delay: The time the signal level must be above the normal level threshold before clearing a fault.

6- Exit Menu: Exits the Menu selection mode and returns to the default display.

When the source does not meet its settings, an alarm notification is obtained from the corresponding status LED (red) on the front panel and from the SOURCE FAULT terminal associated to the source.
