1.0 Description
The Multi Room Audio (MRA) Matrix Switcher is the heart of a C-Bus
enabled audio distribution system. Used in conjunction with Multi Room
Audio Amplifiers, the Matrix Switcher accepts inputs from several audio
sources and distributes them to up to eight zones. Each zone (equipped
with one or more Amplifiers) has control over which source it receives.
Two mono audio inputs are provided to broadcast messages to all zones
simultaneously. These can be used with audio sources such as a door bell,
intercom or public address system.
Audio distribution is performed via digital connection to maintain audio
quality. Amplifiers may be located up to 45 metres from the Matrix
Switcher. C-Bus switches are used in each zone to select the source and
adjust the volume, bass and treble.
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.
2.0 Important Notes
• The Matrix Switcher is suitable for operation in moderate to tropical
climates. It should be mounted indoors only.
• Use only the supplied power cord to connect the unit to the mains
supply. A replacement cord can be purchased from Clipsal Integrated
Systems if required.
• Do not expose the unit to dripping or splashing.
• Do not place objects filled with liquid (such as vases) on the unit.
• Do not cover or block the vents on the Matrix Switcher enclosure.
• The digital audio outputs must only be used with MRA Amplifiers.
• Both C-Bus and digital audio cables are terminated with RJ45
connectors. Never plug either of these cables into the wrong socket.
C-Bus cable is pink. The RJ45 sockets on the rear of the Matrix
Switcher are identified in Figure 1.

3.0 Using the Matrix Switcher
This section describes how to use a Matrix Switcher which has been
installed as part of a Multi Room Audio system. Installation details are
provided in the Multi Room Audio System Installation Manual.
3.1 Powering the Unit
The Matrix Switcher must be plugged into an AC mains power outlet, via
the supplied IEC type cable. A switch is located next to the AC power
socket at the rear of the unit. Push the top of the switch inwards to turn
the Matrix Switcher on.
3.2 Front Panel Control
The front panel of the Matrix Switcher (shown in Figure 2) has eight
buttons which are used to view and control the status of each zone.

The power indicator may be disabled by the installer (using the
MARPA configuration software).
Pressing a Zone selection button displays the name and input source of
the zone (as shown in Figure 3). Pressing the button again within 8
seconds selects the next input source which is routed to the zone.
In a typical Multi Room Audio system installation, there are several ways
to change a zone’s input source. You can do this via:
• a Zone selection button on the Matrix Switcher
• the Source selection buttons on a Desktop Amplifier
• a remote control used with a Desktop Amplifier
• an appropriately configured C-Bus wall switch or touch screen.

4.0 Annunciation
The Matrix Switcher has the capability of announcing the name of an input
source whenever it is selected. This annunciation is broadcast through the
speakers in the zone where the input source has changed.
Annunciation provides instant feedback when changing the source
selection using a C-Bus switch, Amplifier or remote control.
The annunciation feature may be disabled by the installer (using
the MARPA configuration software).

Description
Mono broadcast
inputs (×2)
Line level mono audio connected here is broadcast
to all zones which have an analogue input source
selected.
There are two mono inputs with different priorities.
Audio connected to the LO input is transmitted by
Amplifiers at their current level.
Audio connected to the HI input is transmitted at a
preset level. Amplifiers which have a digital input
source selected, change to the fourth analogue
source so they can receive the high priority
broadcast audio.
Note: High priority (HI) broadcast audio uses left
channel speakers. Low priority (LO)
broadcast audio uses right channel speakers.
USB (Type B) This is used by the installer to configure the Matrix
Switcher.

audio format must be 44.1 or 48 kHz stereo. Some
digital audio formats (such as surround sound) are
not compatible with the Matrix Switcher.
Digital zone
outputs (×8)
Each zone output is used to connect the Matrix
Switcher to one Amplifier in each zone. Additional
Amplifiers can be added to a zone by connecting
their Digital Audio In socket to the Digital Audio
Out of an existing Amplifier.

6.1 Replacing the Fuse
The fuse is located next to the AC power socket on the rear of the Matrix
Switcher (as shown in Figure 5). To replace the fuse:
1) Switch the mains off at the power point. Unplug the power cord at
both ends (the power point and Matrix Switcher).
2) Insert your finger against the right edge of the socket and lift the
fuse compartment outwards.
3) Use a small instrument such as a screwdriver or pen. Insert the
instrument through the hole on the right hand side of the fuse
compartment, and push the fuse out.
4) Insert a replacement 3.15 A Fast Blow 20 × 5 mm fuse.
5) Close the fuse compartment by pushing it inwards.

7.0 Broadcast Audio
The Matrix Switcher includes two broadcast inputs; 1 × high priority
(labelled HI) and 1 × low priority (labelled LO). These allow a mono input
such as a door bell, telephone extender or alarm to be broadcast
throughout the Multi Room Audio system.
Audio connected to the low priority input is broadcast at the currently set
volume, to all amplifiers which are switched on and have Source Input 1, 2,
3 or 4 selected.
Audio connected to the high priority input is broadcast to all amplifiers at
a volume set by the installer (using the MARPA configuration software).
Any Amplifiers which are in standby mode are switched on. All Amplifiers
that are not switched off temporarily change to Source Input 4 to ensure
the audio is broadcast as widely as possible. Five seconds after the
broadcast audio ceases, Amplifiers return to standby (if applicable) and to
their previously set volume.
These actions may vary depending on how the installer has configured the
Matrix Switcher.
Audio connected to a high priority broadcast input must be of
sufficient volume to trigger a broadcast.
A high priority (HI) broadcast uses left channel speakers. A low
priority (LO) broadcast uses right channel speakers.

8.0 Troubleshooting
Symptom Possible Explanation
The Matrix Switcher no longer
responds to button presses.
Switch the Matrix Switcher off for
several seconds, then on. Use the
power switch on the rear of the Matrix
Switcher, next to the AC power socket.
Dynamic labels don’t work on
a C-Bus DLT wall switch.
There are several options which need
to be selected for labels to function.
These options are located:
• on the More panel accessed by
clicking the “More....” button on
the Amplifier’s C-Bus Control tab in
Toolkit
• on the DLT wall switch’s Global tab
in Toolkit
• on the Zones branch of the Project
tree in the MARPA software.
An Amplifier emits a high
pitched screeching sound
when a particular source is
selected.
This may occur if an output of an
Amplifier is connected to the input of
the Matrix Switcher. Such a connection
should be avoided as it can cause a
feedback loop.
The Matrix Switcher does not
power up.
The fuse may need replacing. Fuse
replacement is described on Page 11.
Audio is not broadcast via the
Matrix Switcher’s high priority
(HI) broadcast input.
The level of the audio connected to the
broadcast input may not be sufficient
to trigger the broadcast.
Cannot hear any sound when
using the optical input
The digital audio source may be
connected to the optical output instead
of the input. Some digital audio formats
(such as surround sound) are in-
compatible with the MRA system.
