The most common method of control is via C-Bus switches such as the
Neo, Ulti Saturn and Dynamic Labelling Technology (DLT) range. Buttons
on a C-Bus wall switch can be used to control the volume/on/off
(combined), bass, treble and source selection. A C-Bus wall switch may
provide both lighting and audio control.
Two Dynamic Control buttons may be used to control equipment in
different ways depending on which source is selected. For example such
buttons may be pre-programmed to send IR control codes tailored for the
audio source equipment connected to the MRA system. Whenever the
audio source is changed, the buttons’ IR codes change to match the
selected audio source.
Figure 4 shows an example of a C-Bus DLT wall switch which
has been
configured to control audio in a particular room (zone). The DLT is also
used to control the lights and curtains. When the TV source is selected, the
Dynamic Control buttons are used to change the television channel. When
the Radio source is selected, one Dynamic Control button changes the
radio band (AM/FM) and the other changes the station.

Figure 5 – Possible button assignments on an Ulti Saturn and Neo wall switch
Figure 5 shows possible control configurations for an Ulti Saturn and Neo
wall switch. The top two buttons control a light and the remaining buttons
control audio. The bottom two Neo buttons are used for dynamic control.
Volume buttons are typically multipurpose. A quick-press toggles the
Amplifier between on and standby. A long press (of more than 400 ms)
adjusts the volume. This action may vary depending on how the installer
has configured the system.
