Important Notes
The Multi Room Audio (MRA) Amplifiers are suitable for operation in
moderate to tropical climates. The units should be mounted indoors
only.
MRA Amplifiers disperse heat through the fins on their sides. Ensure
at least 50 mm of free space is available at each side of the Amplifier
for ventilation.
Only use a Clipsal approved power supply to power an MRA Amplifier.
Failure to do so may damage the unit, and void the warranty.
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 Desktop Amp
are identified in Figure 1.

Multi Room Audio Amplifier
3.0
Description
A Multi Room Audio (MRA) Amplifier is used as part of a C-Bus enabled
audio distribution system. It provides audio which is controllable via C-Bus
wall switches and other C-Bus devices such as the C-Touch Colour Touch
Screen.
MRA Amplifiers are typically used in conjunction with the MRA Matrix
Switcher. A Matrix Switcher distributes audio from multiple sources (such
as a radio, TV and CD player) to up to eight zones. (A zone consists of one
or more MRA Amplifiers). An example of this configuration is shown in
Figure 2.

MRA Amplifiers can also be used without a Matrix Switcher. In this case a
Distribution Unit is used to distribute audio from a single source (such as a
radio) to one or more MRA Amplifiers. An example of this configuration is
shown in Figure 3.
In addition to the distributed audio, each MRA Amplifier accepts a local
audio source (local input). This allows you to connect audio from a source
such as a PC or portable audio player, which will be available to the
specific Amplifier only.

Using the Amplifier
This section describes how to use an Amplifier which has been installed as
part of a Multi Room Audio system, or as a standalone unit. Installation
details are provided in the Multi Room Audio System Installation Manual.
There are several methods in which a Multi Room Audio system can be
controlled. The methods will vary depending on how the installer has
configured the system and on which components have been used.

User’s Guide
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.
9
Multi Room Audio Amplifier
Other C-Bus devices may be used to provide control over a Multi Room
Audio system or standalone Amplifier. The C-Touch Colour Touch Screen is
one such example. You can use the Colour Touch Screen to control a Multi
Room Audio system according to a schedule.
4.2
Front Panel Control
The Desktop Amplifier (shown in Figure 6), can be controlled from the
front panel. Table 1 describes its button functions. The Remote Amplifier is
controlled entirely from C-Bus, and has no controls on its front panel.

Reticulated IR
Multi Room Audio Amplifiers can distribute infrared (IR) remote control
signals through to a Matrix Switcher or Distribution Unit. IR is received by
IR Targets installed in a wall or ceiling, or plugged directly into a Desktop
Amplifier (refer to Figure 9). IR is distributed to Emitters which are plugged
into the Matrix Switcher or Distribution Unit, and positioned over the IR
receiver of the audio source equipment.
If reticulated IR has been included in your MRA system, you can control
your source equipment (such as a CD Player and TV) from any room which
is fitted with an MRA IR Target. Simply point the source equipment’s IR
remote control at an IR Target.

Using Headphones
The MRA Desktop Amplifier has a 3.5 mm stereo headphone socket on its
rear panel. This allows you to listen to audio through headphones. In some
installations the headphone output may be connected to a wall plate,
possibly together with local inputs.
Set the volume to a low level before connecting headphones. Once you
have plugged headphones into the Amplifier (either via a wall plate socket
or directly into the Amplifier), press the Mute button for more than 400 ms
to silence the speakers. Refer to Mute in Section 4.2 (Page 11).
13
Multi Room Audio Amplifier
7.0
Local Input
MRA Amplifiers have local input connections on their rear panel in the
form of two RCA type sockets (left and right channel). This allows you to
connect a local line level audio source to the Amplifier, such as a
computer, musical instrument or portable audio player.
In some installations local inputs are wired to a wall plate, for easy access.
In such cases alternative connections may be provided (such as a 3.5 mm
stereo socket).
The local input accepts audio from the line output of audio equipment. Do
not connect higher powered audio signals such as speaker outputs, as this
may damage the Amplifier.

10.0 Troubleshooting
Symptom
Possible Explanation
There is no sound after
switching the Amplifier on
(sound worked previously).
The volume may have been set to
minimum, or the Amplifier may have
been Muted (on a Desktop Amplifier)
before the Amplifier was switched off.
The default volume, bass or
treble settings have changed
(when switching the Amplifier
on).
If a power failure occurs when the
Amplifier is on, the volume, bass and
treble settings are saved and become
the new defaults.
A mains circuit breaker trips
when Amplifiers are powered
up.
This may occur if more than five
Amplifier power supplies are connected
to the same circuit, due to a high inrush
current.
Unexpected behaviour occurs
after the digital zone
connections are changed.
The Amplifier’s zone settings are not
reset until all power is removed from
the Amplifier. Alternatively use the
Reset Amplifier function on the unit’s
C-Bus Status tab in the C-Bus Toolkit
software.
The wrong Amplifier is
responding to source
changes.
The “Use Matrix Switcher auto assigned
zone” option may not be enabled. This
option is in the Amplifier’s Zoning tab
in the C-Bus Toolkit software. After
changing the status of this option (on a
live network), use the Reset Amplifier
function on the C-Bus Status tab.
19
Multi Room Audio Amplifier
Symptom
Possible Explanation
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 switches off,
particularly when the volume
is loud.
If insufficient current is available for the
Amplifier, it will switch itself off. This
may occur if the Amplifier receives its
power from a Matrix Switcher. The
Amplifier may need its own external
power supply unit.
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.
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
Some digital audio formats (such as
surround sound) are incompatible with
the MRA system.
