4) A button on a wall switch can be used to select a specific audio
source (absolute source). This is normally achieved by configuring the
button as a scene. If you program a C-Bus DLT wall switch to select an
absolute source, you must create a Group Address in the Trigger
Control Application and an Action Selector (selector) for each scene.
These allow you to send labels to the DLT scenes. Such a Trigger
Control Group Address with selectors is shown in
Figure 21.

5) Two dynamic control buttons can be used on a wall switch to perform
different functions depending on which source is selected. If you use
dynamic control buttons you must create a Group Address in the
Trigger Control Application and a selector for each function. These
selectors are used when configuring the Matrix Switcher with the
MARPA software. A Trigger Control Group Address with selectors
used in the example MRA system is shown in
Figure 22.
