2.0 Important Notes
• The Matrix Switcher has a built-in C-Bus power supply. Take this into
account when determining the power supply requirement of the
C-Bus network.
• Avoid laying analogue or digital audio cable alongside mains cable, to
minimise EMI interference and signal disruption.
• Do not cover or block the vents on the Matrix Switcher enclosure.
• The Matrix Switcher and Amplifiers of a particular Multi Room Audio
(MRA) system must be connected to the same C-Bus network.
Multiple MRA systems may reside on separate C-Bus networks.
• Only use a Clipsal approved power supply to power an MRA Amplifier
or Distribution Unit. Failure to do so may damage the unit, and void
the warranty.
• Units must be installed in accordance with local authority guidelines.
• The digital audio outputs must only be used with MRA Amplifiers.
3.0 System Overview
The Multi Room Audio Matrix Switcher and Amplifiers provide a C-Bus
enabled audio distribution system.
The Matrix Switcher is installed in a room together with audio sources
such as a radio tuner, CD player and digital TV set top box. Connections
are made to the Amplifiers and to C-Bus.
Amplifiers are installed in each room where audio is to be distributed.
They are connected to speakers and the C-Bus network. Using C-Bus
switches (or the controls on a Desktop Amplifier), each Amplifier can select
different audio sources and adjust the volume, bass and treble.
The Distribution Unit allows a single stereo audio input to be added to the
digital input of the Matrix Switcher. It also allows one distributable stereo
audio input to be plugged into the Amplifiers when no Matrix Switcher is
used (when Amplifiers are used in stand-alone mode).
A typical Multi Room Audio system distributes up to four stereo analogue
audio inputs (five if a Distribution Unit is used), and one stereo optical
digital audio input. These inputs are distributed to up to 8 zones (each
consisting of one or more Amplifiers). A special mono audio input can be
