Multi Room Audio System

5.3 C-Bus Cabling
The Amplifiers and Matrix Switcher in a Multi Room Audio system must be
connected to a common C-Bus network. Use Cat-5 Unshielded Twisted
Pair (UTP) C-Bus cable, and appropriately wired RJ45 plugs and wall plates.
Pinouts and cable conductor assignments are provided in
Figure 6 and
Table 1. Label wall plates to differentiate between ot
her RJ45 connection
types (such as Digital Audio and Ethernet). If colour coding, it is suggested
you use pink for C-Bus, green for Digital Audio and blue for Ethernet.
Use a C-Bus wall switch (such as Ulti Saturn, Neo or Reflection) to control
each zone of the Multi Room Audio system. Switches with Dynamic
Labelling Technology (DLT) can be configured to provide visual feedback
of selected audio sources. Typically, an individual C-Bus wall switch is used
to control both lighting and audio.
In the example installation in
Figure 7, Ulti Saturn and Neo wall switches
are used
in BR2 and BR3 respectively (zones 2 and 3), and DLT wall
switches are used to control the remaining Multi Room Audio zones.
