Device setup
6.2.1.3 Fallback
The fallback function enables the definition of primary (Regular)
and secondary (Fallback) signal paths for analog and digital input
signals with two different modes (Manual or Auto). This ensures
that any secondary or emergency signal fed to the fallback inputs
is transmitted when required.
Note: The fallback and override functions can be used
simultaneously. However, please note that in this case the
chosen override input channel is no longer available as fallback
input.
Selecting «Fallback» from the «Input settings» menu opens the
corresponding subscreen.
Off
When this button is activated (blue), the «Fallback»
function is disabled.
The On/Off status is also displayed on the
«Device setup» screen.
Manual
You can select the desired signal path manually
(«Source») either locally or via the Web Remote
interface or via the d&b Remote network using R1.
Auto Activate and parameterize Input monitoring («Mon»)
to enable the automatic switch (see chapter
Þ Chapter 6.2.1 "Input management" on page 26
for more information about parameterizing).
After the Fallback function has been triggered, you
can reset it manually by selecting the «Regular ½»
input source.
This can be done either locally or via the Web
Remote interface or via the d&b Remote network
using R1.
When the Fallback function is activated, the input routing screen is
divided into two groups, «Regular» and «Fallback». Both groups
can be selected as the source.
1,2 > 3,4
Select any combination of A1, A2, D1, D2 as
your regular input(s).
Select any combination of A3, A4, D3, D4 as
your fallback input(s).
Digital >
Analog
You select from the complete row digital or
analog as regular or fallback.
Note: The input routing settings are stored when the device
switches to fallback mode. When the fallback mode is
deactivated (either manually or automatically), the last input
routing settings defined are restored.
6.2.1.4 Override
The override function is available for input channels.
The override function allows to set an input channel as a major
signal path. When the function is activated, the input channel has
the highest priority for general messages or emergency services.
Fallback targets: 1,2 > 3,4
Fallback targets: Digital > Analog
