User’s Guide 1.0 Product Range 560125D Multi Room Audio Amplifier (Desktop Mounting) 560125R Multi Room Audio Amplifier (Remote Mounting) 2.0 • • • • 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.
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.

Multi Room Audio Amplifier 4.0 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. 4.
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.
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.
User’s Guide Mute Quick press: Sets the audio output (speakers and headphones) to a preset (typically low) level configured by the installer. Returns to the previous volume when pressed again. If the Power button is used to switch between standby and on, the Mute status is retained. Long press: Pressing the button for more than 400 ms causes the speakers (but not headphones) to mute. This state is reversed by another long press.
Multi Room Audio Amplifier 4.3 Desktop Amplifier Remote Control The Desktop Amplifier has an infrared (IR) receiver built into its front panel. This allows you control the Amplifier with an infrared remote such as the MRA Desktop Amplifier Remote Control (shown in Figure 7).
User’s Guide 5.0 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.
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).
User’s Guide 8.0 Rear Panel Connections All connections to the Desktop and Remote Amplifiers are made via the rear panel. Connectors are identified in Figures 10 and 11.
Multi Room Audio Amplifier Connection /Indicator Description Speaker outputs These are used to connect to 4 Ω to 8 Ω speakers which are rated at 25 W RMS @ 4 Ω (or 6 W RMS @ 4 Ω if no external power supply is connected to the Amplifier). Digital audio (zone) input The zone output of the Matrix Switcher is connected to this input. Alternatively a Multi Room Audio Distribution Unit can be connected to this input, providing one stereo audio input.
User’s Guide Connection /Indicator Description Digital optical input Use this to connect a digital optical audio source to the Amplifier instead of the digital audio (zone) source. The digital audio format must be 44.1 or 48 kHz stereo. Some digital audio formats (such as surround sound) are not compatible with the Amplifier. Either a digital audio (zone) or digital optical audio source may be connected to the Amplifier, but not both simultaneously.
Multi Room Audio Amplifier 9.0 Care Instructions Note the following precautions when using Multi Room Audio Amplifiers: • • • • • • • • Clean using a soft lint free cloth. Do not use chemicals or spray cleaners when cleaning. Do not operate with wet hands. Do not use hard, sharp objects to select the controls. Allow adequate ventilation. Do not cover the unit. MRA Amplifiers are designed for indoor use only. Keep the unit away from water and other liquids. Do not expose the unit to high temperatures.
User’s Guide 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.
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.
